In a first step, we just copy (and update) the existing defconfig file for the mpc5121ads board. When new boards get added, the old arch/powerpc/configs/mpc5121_defconfig file will get adjusted to allow for a generic kernel image for MPC512x based boards.

For some reason which I don't understand yet, the Ethernet interface on the ARIA board does not work in the default configuration, because MII probing fails. What I'm seeing is this; the problem is with this part of code in "drivers/net/fs_enet/mii-fec.c": 156 fec->mii_speed = ((ppc_proc_freq + 4999999) / 5000000) << 1; ... 163 out_be32(&fec->fecp->fec_mii_speed, fec->mii_speed); I added some debug messages, and this is what I see: On the ADS5121, we have the CPU clocked at 400 MHz. I get: ... ## ppc_proc_freq = 399999996, fec->mii_speed = 160 FEC MII Bus: probed ... It works fine. According to the Ref. Man.: A value of 0 in this field turns off the MDC and leaves it in a low-voltage state. Any non-zero value results in the MDC frequency of 1/(mii_speed*2) of the system clock frequency. that means we have a MDC frequency of 400 MHz / (2 * 160) = 1.25 MHz which is obviously within the 2.5 MHz limit. Now ARIA is currently running at 316.8 MHz, and this is what I get: ... ## ppc_proc_freq = 316800000, fec->mii_speed = 128 fsl-fec-mdio: probe of 80002800.mdio failed with error -5 ... It fails. MDC frequency is 316.8 MHz / (2 * 128) = 1.24 MHz which should be fine. However, If I change the code to fec->mii_speed = (((ppc_proc_freq / 1000000) / 30) + 1) << 1; then I get: ... ## ppc_proc_freq = 316800000, fec->mii_speed = 22 FEC MII Bus: probed ... and it's working!!! However, I compute MDC frequency as 316.8 MHz / (2 * 22) = 7.2 MHz which is far above the maximum allowed clock of 2.5 MHz ???

Good idea. The RM documents the register at offset 0x44 and describes it as 32 bits... and it's working fine on the MPC5121ADS board, but fails on ARIA. Thanks.

OK, this is just a guess too: Some odd byte order requirements? No more ideas, sorry. Jocke ^ permalink raw reply [flat|nested] 54+ messages in thread

(3F << 1). The Freescale code tries to address this, but just clipping the data is incorrect as we can see above. The funny thing is that the RefMan says: "...MDC frequency of 1/(mii_speed*2) of the system clock frequency" "To be compliant with the IEEE MII specification, the MII_SPEED field must be programmed with a value that provides an MDC frequency of less than or equal to 2.5 MHz." The big question seems to be what the RefMan means when talking about the "system clock frequency". Obiously it is NOT the CPU clock as code variants above assume. The examples in "Table 17-24. Programming Examples for MII_SPEED Register" list "system clock frequencies" of 25, 33, 40 and 50 MHz - which also indiocates that some other frequency might be referenced here. But which one is it?

I think I stated in a I fully agree. a) Table 16-18 in the manual mentions ips and the values given there look much more like ips than ppc_proc_freq (25MHz?) b) the excerpt from clock.c Wolfgang posted mentions ips as parent c) I cannot imagine a divider wrapping around at a frequency which is inside the range of what the processor is capable of. MII only up to 300MHz seems like a show-stopper to me :) d) According to the MPC5200B-manual, ipb _is_ used there (and the linux-driver adheres to that).

Yes, it seems very much as if you were right again. When using ips/ibp everything makes sense, and works. Hm... so that means on MPC512x we should use mpc512x_find_ips_freq(), while on MPC5200 we should use mpc52xx_find_ipb_freq() - but hey, apart from the name these two functions are identical.

What about implementing the more generic clk api for the MPC5200 as done for the MPC512x? http://lxr.linux.no/linux+v2.6.29/arch/powerpc/platforms/512x/clock.c The MSCAN can also operate with other clock sources, e.g. the external oscillator (ref_clk).

Seeing as the function just walks up the parent nodes looking for the "bus-frequency" property; how about "mpc5xxx_get_bus_frequency()"? It should go somewhere in arch/powerpc/sysdev/ Alternately, it is a pretty trivial function; 52xx and 512x could both have their own versions of it. Whichever makes the most sense to you (I haven't personally looked at the device driver impact). g. --=20 Grant Likely, B.Sc., P.Eng.

* [PATCH] mpc5xxx_get_bus_frequency(): use common code on MPC512x and MPC52xx 2009-06-08 14:37 ` Grant Likely @ 2009-06-11 20:19 ` Wolfgang Denk 2009-06-17 6:14 ` Grant Likely 2009-06-11 20:19 ` [PATCH RFC] fs_enet/mii-fec.c: fix MII speed calculation Wolfgang Denk 1 sibling, 1 reply; 54+ messages in thread From: Wolfgang Denk @ 2009-06-11 20:19 UTC (permalink / raw) To: linuxppc-dev; +Cc: Wolfgang Denk So far, MPC512x used mpc512x_find_ips_freq() to get the bus frequency, while MPC52xx used mpc52xx_find_ipb_freq(). Despite the different clock names (IPS vs. IPB) the code was identical. Use common code for both processor families.

* [PATCH RFC] fs_enet/mii-fec.c: fix MII speed calculation 2009-06-08 14:37 ` Grant Likely 2009-06-11 20:19 ` [PATCH] mpc5xxx_get_bus_frequency(): use common code on MPC512x and MPC52xx Wolfgang Denk @ 2009-06-11 20:19 ` Wolfgang Denk 2009-07-14 13:42 ` [PATCH v2] " Wolfgang Denk 1 sibling, 1 reply; 54+ messages in thread From: Wolfgang Denk @ 2009-06-11 20:19 UTC (permalink / raw) To: linuxppc-dev; +Cc: Wolfgang Denk The MII speed calculation was incorrectly based on the CPU clock (ppc_proc_freq) instead of the bus clock; it worked only by chance and for some CPU clock frequencies. This patch makes it use the correct clock and adds some error handling. Signed-off-by: Wolfgang Denk <wd@denx.de> Cc: Grant Likely <grant.likely@secretlab.ca> Cc: Kumar Gala <galak@kernel.crashing.org> --- This is mostly a fix for an old bug - it's starnge that this went unnoticed so far. It worked only because the incorrectly computed value was truncated due to the fact that the MII_SPEED field in the rebister is only 6 bits wide - but, depending on the system clock frequency, non working systems (MII_SPEED set to zero or DIS_PREAMBLE set to one) might result as well. This patch is marked a RFC for the following reasons: 1) drivers/net/fs_enet/mii-fec.c now uses mpc5xxx_get_mii_speed() which makes it 5xxx specific. I don't really like this, but did not see a clean way to avoid it either. 2) We probably should also use mpc5xxx_get_mii_speed() in drivers/net/fec_mpc52xx.c and drivers/net/fec_mpc52xx_phy.c, which also contain code to calculate the MII speed. But then we should also add some error checking to the code there, and we should make sure that only the bits that belong to the MII_SPEED field get written when setting the MII speed. I'm not sure if such changes are considered necessary, and if, if they should be added to this patch or handled in a separate one. arch/powerpc/sysdev/mpc5xxx_clocks.c | 37 ++++++++++++++++++++++++++++++++++ drivers/net/fs_enet/mii-fec.c | 9 ++++++- 2 files changed, 44 insertions(+), 2 deletions(-) diff --git a/arch/powerpc/sysdev/mpc5xxx_clocks.c b/arch/powerpc/sysdev/mpc5xxx_clocks.c index 34e12f9..3e9584b 100644 --- a/arch/powerpc/sysdev/mpc5xxx_clocks.c +++ b/arch/powerpc/sysdev/mpc5xxx_clocks.c @@ -31,3 +31,40 @@ mpc5xxx_get_bus_frequency(struct device_node *node) return p_bus_freq ? *p_bus_freq : 0; } EXPORT_SYMBOL(mpc5xxx_get_bus_frequency); + +/** + * mpc5xxx_get_get_mii_speed - Get the MII_SPEED value + * @node: device node + * + * Returns the MII_SPEED value for MPC512x and MPC52xx systems. + * The value gets computed such that the resulting MDC frequency + * is 2.5 MHz or lower. + */ + +int +mpc5xxx_get_mii_speed(struct of_device *ofdev) +{ + unsigned int clock, speed; + + clock = mpc5xxx_get_bus_frequency(ofdev->node); + + if (!clock) { + dev_err(&ofdev->dev, "could not determine IPS/IPB clock\n"); + return -ENODEV; + } + + /* scale for a MII clock <= 2.5 MHz */ + speed = (clock + 2499999) / 2500000; + + /* only 6 bits available for MII speed */ + if (speed > 0x3F) { + speed = 0x3F; + dev_err(&ofdev->dev, + "MII clock (%d MHz) exceeds max (2.5 MHz)\n", + clock / speed); + } + + /* Field is in bits 25:30 of MII_SPEED register */ + return speed << 1; +} +EXPORT_SYMBOL(mpc5xxx_get_mii_speed); diff --git a/drivers/net/fs_enet/mii-fec.c b/drivers/net/fs_enet/mii-fec.c index 28077cc..a2693b4 100644 --- a/drivers/net/fs_enet/mii-fec.c +++ b/drivers/net/fs_enet/mii-fec.c @@ -36,6 +36,7 @@ #include <asm/pgtable.h> #include <asm/irq.h> #include <asm/uaccess.h> +#include <asm/mpc5xxx.h> #include "fs_enet.h" #include "fec.h" @@ -152,13 +153,17 @@ static int __devinit fs_enet_mdio_probe(struct of_device *ofdev, if (!fec->fecp) goto out_fec; - fec->mii_speed = ((ppc_proc_freq + 4999999) / 5000000) << 1; + i = mpc5xxx_get_mii_speed(ofdev); + if (i < 0) + goto out_unmap_regs; + + fec->mii_speed = i; setbits32(&fec->fecp->fec_r_cntrl, FEC_RCNTRL_MII_MODE); setbits32(&fec->fecp->fec_ecntrl, FEC_ECNTRL_PINMUX | FEC_ECNTRL_ETHER_EN); out_be32(&fec->fecp->fec_ievent, FEC_ENET_MII); - out_be32(&fec->fecp->fec_mii_speed, fec->mii_speed); + clrsetbits_be32(&fec->fecp->fec_mii_speed, 0x7E, fec->mii_speed); new_bus->phy_mask = ~0; new_bus->irq = kmalloc(sizeof(int) * PHY_MAX_ADDR, GFP_KERNEL); -- 1.6.0.6 ^ permalink raw reply related [flat|nested] 54+ messages in thread

The 5200 and 5121 are different devices and it is a tiny bit of code. I don't think there is any benefit to having it as a common function. Just roll the get_mii_speed function in the mii-fec driver itself. Also, this patch can be quite a bit simpler if you use the .data pointer in the drivers match table to specify the function used to return the bus clock speed. Something like this: static struct of_device_id fs_enet_mdio_fec_match[] =3D { { .compatible =3D "fsl,pq1-fec-mdio", }, #if defined(CONFIG_PPC_MPC512x) { .compatible =3D "fsl,mpc5121-fec-mdio", .data =3D mpc5xxx_get_bus_frequency, }, #endif {}, }; and int *get_bus_freq(of_node *) =3D data; if (get_bus_freq) bus_freq =3D get_bus_freq(np); else bus_freq =3D ppc_proc_freq / 2; ... then do the regular calculation here and add in the additional robustification you did in this patch. Heck, you could even eliminate the if/else above if the normal case you have a get_bus_speed function for the original ppc_proc_freq case, but I'm not sure if it is worth it. > =A0drivers/net/fs_enet/mii-fec.c =A0 =A0 =A0 =A0| =A0 13 +++++++++-- > =A03 files changed, 57 insertions(+), 3 deletions(-) > > diff --git a/arch/powerpc/include/asm/mpc5xxx.h b/arch/powerpc/include/as= m/mpc5xxx.h > index 5ce9c5f..86ab29f 100644 > --- a/arch/powerpc/include/asm/mpc5xxx.h > +++ b/arch/powerpc/include/asm/mpc5xxx.h > @@ -15,8 +15,18 @@ > > =A0#ifndef __ASM_POWERPC_MPC5xxx_H__ > =A0#define __ASM_POWERPC_MPC5xxx_H__ > +#include <linux/of_platform.h> > > =A0extern unsigned long mpc5xxx_get_bus_frequency(struct device_node *nod= e); > > +#if defined(CONFIG_PPC_MPC512x) || defined(CONFIG_PPC_MPC52xx) > +extern int mpc5xxx_get_mii_speed(struct of_device *ofdev); > +#else > +static inline int mpc5xxx_get_mii_speed(struct of_device *ofdev) > +{ > + =A0 =A0 =A0 return -1; > +} > +#endif > + > =A0#endif /* __ASM_POWERPC_MPC5xxx_H__ */ > > diff --git a/arch/powerpc/sysdev/mpc5xxx_clocks.c b/arch/powerpc/sysdev/m= pc5xxx_clocks.c > index 34e12f9..e26d12b 100644 > --- a/arch/powerpc/sysdev/mpc5xxx_clocks.c > +++ b/arch/powerpc/sysdev/mpc5xxx_clocks.c > @@ -31,3 +31,40 @@ mpc5xxx_get_bus_frequency(struct device_node *node) > =A0 =A0 =A0 =A0return p_bus_freq ? *p_bus_freq : 0; > =A0} > =A0EXPORT_SYMBOL(mpc5xxx_get_bus_frequency); > + > +/** > + * =A0 =A0 mpc5xxx_get_mii_speed - Get the MII_SPEED value > + * =A0 =A0 @node: =A0device node > + * > + * =A0 =A0 Returns the MII_SPEED value for MPC512x and MPC52xx systems. > + * =A0 =A0 The value gets computed such that the resulting MDC frequency > + * =A0 =A0 is 2.5 MHz or lower. > + */ > + > +int > +mpc5xxx_get_mii_speed(struct of_device *ofdev) > +{ > + =A0 =A0 =A0 unsigned int clock, speed; > + > + =A0 =A0 =A0 clock =3D mpc5xxx_get_bus_frequency(ofdev->node); > + > + =A0 =A0 =A0 if (!clock) { > + =A0 =A0 =A0 =A0 =A0 =A0 =A0 dev_err(&ofdev->dev, "could not determine I= PS/IPB clock\n"); > + =A0 =A0 =A0 =A0 =A0 =A0 =A0 return -ENODEV; > + =A0 =A0 =A0 } > + > + =A0 =A0 =A0 /* scale for a MII clock <=3D 2.5 MHz */ > + =A0 =A0 =A0 speed =3D (clock + 2499999) / 2500000; > + > + =A0 =A0 =A0 /* only 6 bits available for MII speed */ > + =A0 =A0 =A0 if (speed > 0x3F) { > + =A0 =A0 =A0 =A0 =A0 =A0 =A0 speed =3D 0x3F; > + =A0 =A0 =A0 =A0 =A0 =A0 =A0 dev_err(&ofdev->dev, > + =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 "MII clock (%d MHz) exceeds= max (2.5 MHz)\n", > + =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 clock / speed); > + =A0 =A0 =A0 } > + > + =A0 =A0 =A0 /* Field is in bits 25:30 of MII_SPEED register */ > + =A0 =A0 =A0 return speed << 1; > +} > +EXPORT_SYMBOL(mpc5xxx_get_mii_speed); > diff --git a/drivers/net/fs_enet/mii-fec.c b/drivers/net/fs_enet/mii-fec.= c > index 75a0999..a28d39f 100644 > --- a/drivers/net/fs_enet/mii-fec.c > +++ b/drivers/net/fs_enet/mii-fec.c > @@ -36,6 +36,7 @@ > =A0#include <asm/pgtable.h> > =A0#include <asm/irq.h> > =A0#include <asm/uaccess.h> > +#include <asm/mpc5xxx.h> > > =A0#include "fs_enet.h" > =A0#include "fec.h" > @@ -103,7 +104,6 @@ static int fs_enet_fec_mii_reset(struct mii_bus *bus) > =A0static int __devinit fs_enet_mdio_probe(struct of_device *ofdev, > =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 = =A0 =A0 const struct of_device_id *match) > =A0{ > - =A0 =A0 =A0 struct device_node *np =3D NULL; > =A0 =A0 =A0 =A0struct resource res; > =A0 =A0 =A0 =A0struct mii_bus *new_bus; > =A0 =A0 =A0 =A0struct fec_info *fec; > @@ -133,13 +133,20 @@ static int __devinit fs_enet_mdio_probe(struct of_d= evice *ofdev, > =A0 =A0 =A0 =A0if (!fec->fecp) > =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0goto out_fec; > > - =A0 =A0 =A0 fec->mii_speed =3D ((ppc_proc_freq + 4999999) / 5000000) <<= 1; > + =A0 =A0 =A0 if (of_device_is_compatible(ofdev->node, "fsl,mpc5121-fec-m= dio")) { > + =A0 =A0 =A0 =A0 =A0 =A0 =A0 i =3D mpc5xxx_get_mii_speed(ofdev); > + =A0 =A0 =A0 =A0 =A0 =A0 =A0 if (i < 0) > + =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 goto out_unmap_regs; > + =A0 =A0 =A0 =A0 =A0 =A0 =A0 fec->mii_speed =3D i; > + =A0 =A0 =A0 } else { > + =A0 =A0 =A0 =A0 =A0 =A0 =A0 fec->mii_speed =3D ((ppc_proc_freq + 499999= 9) / 5000000) << 1; > + =A0 =A0 =A0 } > > =A0 =A0 =A0 =A0setbits32(&fec->fecp->fec_r_cntrl, FEC_RCNTRL_MII_MODE); > =A0 =A0 =A0 =A0setbits32(&fec->fecp->fec_ecntrl, FEC_ECNTRL_PINMUX | > =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 = =A0 =A0 =A0FEC_ECNTRL_ETHER_EN); > =A0 =A0 =A0 =A0out_be32(&fec->fecp->fec_ievent, FEC_ENET_MII); > - =A0 =A0 =A0 out_be32(&fec->fecp->fec_mii_speed, fec->mii_speed); > + =A0 =A0 =A0 clrsetbits_be32(&fec->fecp->fec_mii_speed, 0x7E, fec->mii_s= peed); > > =A0 =A0 =A0 =A0new_bus->phy_mask =3D ~0; > =A0 =A0 =A0 =A0new_bus->irq =3D kmalloc(sizeof(int) * PHY_MAX_ADDR, GFP_K= ERNEL); > -- > 1.6.0.6 > > --=20 Grant Likely, B.Sc., P.Eng.

No, there's a deeper issues here. I'm bothered that the mac driver is impacting the mdio driver. I'd like to find a way for this whole thing to be handled cleaner, and not have two different drivers calculate it. g. > > > Best regards, > > Wolfgang Denk > > -- > DENX Software Engineering GmbH, =A0 =A0 MD: Wolfgang Denk & Detlev Zundel > HRB 165235 Munich, Office: Kirchenstr.5, D-82194 Groebenzell, Germany > Phone: (+49)-8142-66989-10 Fax: (+49)-8142-66989-80 Email: wd@denx.de > What is mind? =A0No matter. =A0What is matter? =A0Never mind. > =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 = =A0-- Thomas Hewitt Key, 1799-1875 > --=20 Grant Likely, B.Sc., P.Eng.
