[PATCH 1/3] ARM: dts: Fix WLAN regression on omap5-uevm

[Tony Lindgren]

Commit 99f84cae43df ("ARM: dts: add wl12xx/wl18xx bindings") added
device tree bindings for the TI WLAN SDIO on many omap variants.

I recall wondering how come omap5-uevm did not have the WLAN
added and this issue has been bugging me for a while now, and
I finally tracked it down to a bad pinmux regression, and a missing
deferred probe handling for the 32k clock from palmas that's
requested by twl6040.

Basically 392adaf796b9 ("ARM: dts: omap5-evm: Add mcspi data")
added pin muxing for mcspi4 that conflicts with the onboard
WLAN. While some omap5-uevm don't have WLAN populated, the
pins are not reused for other devices. And as the SDIO bus
should be probed, let's try to enable WLAN by default.

Let's fix the regression and add the WLAN configuration as
done for the other boards in 99f84cae43df ("ARM: dts: add
wl12xx/wl18xx bindings"). And let's use the new MMC pwrseq for
the 32k clock as suggested by Javier Martinez Canillas
<javier@dowhile0.org>.

Note that without a related deferred probe fix for twl6040,
the 32k clock is not initialized if palmas-clk is a module
and twl6040 is built-in.

Let's also use the generic "non-removable" instead of the
legacy "ti,non-removable" property while at it.

And finally, note that omap5 seems to require WAKEUP_EN for
the WLAN GPIO interrupt.

[PATCH 2/3] ARM: dts: Move most of omap5-uevm.dts to omap5-board-common.dtsi

[Tony Lindgren]

Looks like thevarious omap5-uevm models and igepv5 are very similar. So let's
create omap5-board-common.dtsi to allow fixing up things properly for mainline
kernel to support all these.

Even if we eventually end up having only PMIC + MMC + eMMC + SDIO WLAN + SATA +
USB + HDMI configuration in the omap5-board-common.dtsi, this is the easiest
way to add support for other boards rather than diffing various versions of
out of tree dts files.

My guess is that also omap5-sbc-t54.dts can use this, but I don't have that
board so that will need to be dealt with later on.

[PATCH 3/3] ARM: dts: Add basic support for isee igepv5

[Tony Lindgren]

With omap5-board-common.dtsi, we can now easily add support for various omap5
board variants. Let's add minimal support for isee igepv5.

So far I've tested that basic things work, such as serial, USB Ethernet, HDMI
and WLAN.

Note that like omap5-uevm, these boards seem to need to reserve 16MB for a
trap section as in commit 03178c66d289 ("ARM: dts: omap5-evm: Update
available memory to 2032 MB") and also noted in a u-boot commit at
http://marc.info/?l=u-boot&m=134376852603255 and also at
http://patchwork.ozlabs.org/patch/159881/.

Not sure why this is not needed for omap5-cm-t54.dts, maybe because of
different u-boot configuration.

Enric, can you please check if there are some critical pieces compared
to omap5-uevm that should be updated for this patch?

Unfortunately I don't have the schematic and any IGEPv5 to verify your
patches. From a quick view I can say that it's ok but let me cc
Agust?, Eduard and Pau that will have access to the hardware and the
schematics.

Cheers,

Enric

OK thanks. The thing to do is check against the omap5-board-common.dtsi in
this patch series so there's nothing unsuitable in omap5-board-common.dtsi
that needs an override in omap5-igep0050.dts.

Also mSATA works too BTW.

I'm using the isee git tree u-boot with the following enabled in the
omap5_igep0050.h:

#define IGEPv5_MEMORY_4G
#define CONFIG_SUPPORT_RAW_INITRD
#define CONFIG_ENV_IS_IN_FAT
#define FAT_ENV_INTERFACE		"mmc"
#define FAT_ENV_DEVICE			1
#define FAT_ENV_PART			1
#define FAT_ENV_FILE			"uboot.env"
#define CONFIG_FAT_WRITE

The CONFIG_SUPPORT_RAW_INITRD is needed to support raw initramfs instead of
using mkimage on it for bootz command. I don't think these changes should
affect booting though.

Looks like I only enabled CONFIG_USB_NET_SMSC75XX.

My guess is that you need to play with initrd_high etc, try doing something
like this in u-boot:

setenv fdtaddr 80a00000
setenv loadaddr 80c00000
setenv rdaddr 81400000
setenv fdt_high 8c000000
setenv initrd_high ffffffff

And see if that helps?

BTW, we really need to use initramfs based booting on these for NFS to
avoid having to compile all the USB into the kernel. Well at least for
the mainline omap2plus_defconfig.

Tony

OK good to hear. Applying this series into omap-for-v4.4/dt then.

Thanks,
