Support for HTKW mcx

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.

1.7.6.4

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

Grant, care to ack this one?

Actually a version of this you already acked as
"[PATCH 1/2] mt_ventoux: very basic support for TeeJet Mt.Ventoux board" so using that instead

Regards,

Tony

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

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.
