Hi all,
The patch series are used to support SPI via the OF SPI subsystem
(driver/of/of_spi.c). Now the driver is able to manage its own
chip selects, and doesn't need any auxiliary support from the
board files or fsl_soc constructors.
The series also contains PowerPC portions of the MMC SPI support.
Since the series touches spi and powerpc trees, I think it would
be most convenient to pass it via one of these trees. The patches
doesn't touch any SPI functionality, only some probe routines, so
I believe powerpc.git is the best candidate...
The other reason for powerpc tree is that the patches depends on
other patches as found in paulus/powerpc.git + of_gpio_count()
as found here:
http://ozlabs.org/pipermail/linuxppc-dev/2008-December/065917.html
David, if you're OK with the patches, may I ask you to sign off on
the ones that touch drivers/spi so that we could pass it via Kumar's
powerpc.git?
The queue:
[1/7] powerpc: Implement get_brgfreq() and get_baudrate() stubs
[2/7] spi_mpc83xx: Fix sparse warnings
[3/7] spi_mpc83xx: Rework chip selects handling
[4/7] spi_mpc83xx: Add OF platform driver bindings
[5/7] powerpc/fsl_soc: Isolate legacy fsl_spi support to mpc832x_rdb boards
[6/7] powerpc: Add mmc-spi-slot bindings
[7/7] powerpc/83xx: Add mmc-spi support via the device tree for MPC8323E-RDB
Thanks,

* [PATCH 4/7] spi_mpc83xx: Add OF platform driver bindings @ 2008-12-05 20:10 ` Anton Vorontsov 0 siblings, 0 replies; 72+ messages in thread From: Anton Vorontsov @ 2008-12-05 20:10 UTC (permalink / raw) To: Kumar Gala, David Brownell; +Cc: linuxppc-dev, spi-devel-general This patch implements full support for OF SPI bindings. Now the driver can manage its own chip selects without any help from the board files and/or fsl_soc constructors. The "legacy" code is well isolated and could be removed as time goes by.

* [PATCH 2/6] spi_mpc83xx: Rework chip selects handling 2009-01-23 19:49 ` Anton Vorontsov (?) @ 2009-01-23 19:50 ` Anton Vorontsov -1 siblings, 0 replies; 72+ messages in thread From: Anton Vorontsov @ 2009-01-23 19:50 UTC (permalink / raw) To: David Brownell Cc: linux-kernel-u79uwXL29TY76Z2rM5mHXA, linuxppc-dev-mnsaURCQ41sdnm+yROfE0A, spi-devel-general-5NWGOfrQmneRv+LV9MX5uipxlwaOVQ5f, Andrew Morton The main purpose of this patch is to pass 'struct spi_device' to the chip select handling routines. This is needed so that we could implement full-fledged OpenFirmware support for this driver. While at it, also: - Replace two {de,activate}_cs routines by single cs_contol(). - Don't duplicate platform data callbacks in mpc83xx_spi struct.

* [PATCH v2 2/2] powerpc/83xx: Move gianfar mdio nodes under the ethernet nodes @ 2009-03-17 18:59 Anton Vorontsov 2009-03-18 13:21 ` Kumar Gala 0 siblings, 1 reply; 72+ messages in thread From: Anton Vorontsov @ 2009-03-17 18:59 UTC (permalink / raw) To: Kumar Gala; +Cc: Scott Wood, linuxppc-dev, Li Yang Currently it doesn't matter where the mdio nodes are placed, but with power management support (i.e. when sleep = <> properties will take effect), mdio nodes placement will become important: mdio controller is a part of the ethernet block, so the mdio nodes should be placed correctly. Otherwise we may wrongly assume that MDIO controllers are available during sleep.

Yeah - basically Jon got busy with other things, so we no longer had critical mass to keep things moving. I have an idea for a partway step that will be enough for at least some applications without making life awkward for a more complete approach later. Basically the idea is just to have "weak" property assignments - you can have an include file which has a bunch of these, but they can be silently overriden by normal property assignments afterwards. -- David Gibson | I'll have my music baroque, and my code david AT gibson.dropbear.id.au | minimalist, thank you.

* [PATCH v3 1/4] powerpc/83xx: Add power management support for MPC837x boards 2009-03-18 19:59 ` Anton Vorontsov @ 2009-03-18 20:00 ` Anton Vorontsov 2009-03-18 20:00 ` [PATCH v3 2/4] powerpc/83xx: Move gianfar mdio nodes under the ethernet nodes Anton Vorontsov ` (2 subsequent siblings) 3 siblings, 0 replies; 72+ messages in thread From: Anton Vorontsov @ 2009-03-18 20:00 UTC (permalink / raw) To: Kumar Gala; +Cc: Scott Wood, linuxppc-dev, Li Yang This patch adds pmc nodes to the device tree files so that the boards will able to use standby capability of MPC837x processors. The MPC837x PMC controllers are compatible with MPC8349 ones (i.e. no deep sleep). sleep = <> properties are used to specify SCCR masks as described in "Specifying Device Power Management Information (sleep property)" chapter in Documentation/powerpc/booting-without-of.txt. Since I2C1 and eSDHC controllers share the same clock source, they are now placed under sleep-nexus nodes. A processor is able to wakeup the boards on LAN events (Wake-On-Lan), console events (with no_console_suspend kernel command line), GPIO events and external IRQs (IRQ1 and IRQ2). The processor can also wakeup the boards by the fourth general purpose timer in GTM1 block, but the GTM wakeup support isn't yet implemented (it's tested to work, but it's unclear how can we use the quite short GTM timers, and how do we want to expose the GTM to userspace).

Otherwise we may wrongly assume that MDIO controllers are available during sleep.

Otherwise we may wrongly assume that MDIO controllers are available during sleep. NOTE: mpc8572ds_camp_core1.dts now fully specifies ethernet@24000 layout. ethernet@24000 node is disabled via status = "disabled on core1" property.

Technically, yes. In practice, MDIO and MAC drivers are probed separately.

Dunno. From simply looking into the device tree, I'd assume the same.

I mean do you see any problem with giving Linux knowledge of the -slave name? p.s. Actually, we can stay with status = ".." property, and if things ever change, it's always driver's duty to check for of_device_is_available(), and so the driver can simply check for if (!strcmp(status, "disabled on core")) probe_children_only(). -- Anton Vorontsov email: cbouatmailru@gmail.com irc://irc.freenode.net/bd2 ^ permalink raw reply [flat|nested] 72+ messages in thread

So that's just a bit complicated GPIO controller. I believe you should describe it in the device tree and use it's muxed lines as usual GPIOs.
