Split into two parts:
 1. Device tree only to be used with board-generic (only serial works)
 2. Full board support via custom machine file for board-testing

Sorry for double-posting: I've put wrong linux-arm-kernel address in
the first post.

Very basic support for HTKW mcx board. Able to boot via board-generic
and ramdisk/initramfs, however most of peripherals is unsupported.
Produces tons of twl4030 related errors as this board doesn't have
twl4030 installed.

Changes from V2:

 - None

Changes from V1:

 - device tree move to the separate patch
 - iva node is disabled instead of using custom includes
 - removed bootargs entry

Support for the HTKW mcx board (TI AM3517 based) including serial,
Ethernet, I2C, USB host, HSMMC, DSS and RTC.

Requires updated machine-type file, recently posted AM35xx-EMAC patch
and "Disable PM init on AM35{05,17} patch.

Changes from V2:
 - Rebased onto the current linux-omap/master
  - Added "common.h" include
  - Added .handle_irq field to machine description
  - Added omap_sdrc_init() call
 - Removed unneeded pullup from output pins
 - Moved pin muxing before GPIO accesses
 - Removed .ocr_mask field (it's overwritten anyway)
 - Moved touchscreen init out of I2C init
 - some readability improvements (empty lines, comments)

Changes from V1:
 - Kconfig option name fixed
 - Makefile entry sanitized
 - Unneeded headers removed
 - EMAC initialization moved to separate file/patch
 - Use gpio_{request,free}_{array,one} where possible
 - don't use platform data for touchscreen, we only need to pass
   irq number, do it via client.irq
 - check mcx_ts_init return value
 - Moved DEBUG_LL_OMAP3 entry to be in aplhabetical order
 - check return value of gpio_request for USB pwr pin
 - use pr_err instead of printk for error printing
 - added a fixed regulator for vdds_dsi
 - added SDcard card-detect pin

* [PATCH V3 2/2] mcx: support for HTKW mcx board
@ 2011-12-21 15:53   ` Ilya Yanok

From: Ilya Yanok @ 2011-12-21 15:53 UTC (permalink / raw)
  To: linux-arm-kernel

Support for the HTKW mcx board (TI AM3517 based) including serial,
Ethernet, I2C, USB host, HSMMC, DSS and RTC.

Signed-off-by: Ilya Yanok <yanok@emcraft.com>

---
Requires updated machine-type file, recently posted AM35xx-EMAC patch
and "Disable PM init on AM35{05,17} patch.

Changes from V2:
 - Rebased onto the current linux-omap/master
  - Added "common.h" include
  - Added .handle_irq field to machine description
  - Added omap_sdrc_init() call
 - Removed unneeded pullup from output pins
 - Moved pin muxing before GPIO accesses
 - Removed .ocr_mask field (it's overwritten anyway)
 - Moved touchscreen init out of I2C init
 - some readability improvements (empty lines, comments)

Changes from V1:
 - Kconfig option name fixed
 - Makefile entry sanitized
 - Unneeded headers removed
 - EMAC initialization moved to separate file/patch
 - Use gpio_{request,free}_{array,one} where possible
 - don't use platform data for touchscreen, we only need to pass
   irq number, do it via client.irq
 - check mcx_ts_init return value
 - Moved DEBUG_LL_OMAP3 entry to be in aplhabetical order
 - check return value of gpio_request for USB pwr pin
 - use pr_err instead of printk for error printing
 - added a fixed regulator for vdds_dsi
 - added SDcard card-detect pin

This one I can carry in testing-board until device tree works
for us in a usable way. But probably some rebasing is needed
for this after the hsmmc stuff is cleared out of the way.

Actually a version of this you already acked as

Support for the HTKW mcx board (TI AM3517 based) including serial,
Ethernet, I2C, USB host, HSMMC, DSS and RTC.

Signed-off-by: Ilya Yanok <yanok@emcraft.com>

---
Requires updated machine-type file, recently posted AM35xx-EMAC patch
and "Disable PM init on AM35{05,17} patch.

Changes from V2:
 - Rebased onto the current linux-omap/master
  - Added "common.h" include
  - Added .handle_irq field to machine description
  - Added omap_sdrc_init() call
 - Removed unneeded pullup from output pins
 - Moved pin muxing before GPIO accesses
 - Removed .ocr_mask field (it's overwritten anyway)
 - Moved touchscreen init out of I2C init
 - some readability improvements (empty lines, comments)

Changes from V1:
 - Kconfig option name fixed
 - Makefile entry sanitized
 - Unneeded headers removed
 - EMAC initialization moved to separate file/patch
 - Use gpio_{request,free}_{array,one} where possible
 - don't use platform data for touchscreen, we only need to pass
   irq number, do it via client.irq
 - check mcx_ts_init return value
 - Moved DEBUG_LL_OMAP3 entry to be in aplhabetical order
 - check return value of gpio_request for USB pwr pin
 - use pr_err instead of printk for error printing
 - added a fixed regulator for vdds_dsi
 - added SDcard card-detect pin
