Subject: [PATCH v2 00/11] ARM:STixxxx: Add STixxxx platform and board support

Here is new patch-set incorporating all the review comments.

This patch-set adds basic support for STMicroelectronics STixxxx SOCs
which includes STiH415 and STiH416 with B2000 and B2020 board support.

STiH415 and STiH416 are dual-core ARM Cortex-A9 CPU, designed for use in
Set-top-boxes. The SOC support is available in mach-stixxxx which contains
support code for STiH415, STiH416 SOCs including the generic board support.

Only device drivers included in this patch set are UART and pinctrl, other
drivers will be added in future.

The reason for adding two SOCs at this patch set is to show that no new
C code is required for second SOC(STiH416) support.

Thankyou all for reviewing the first set of RFC patches.
I would appreciate any feedback on these patches.

Changes since RFC:
 - st-asc Serial driver:
	- modified kconfig to remove default y
	- removed all the forward declaration.
	- use dynamic major numbering.
	- merge header-file in to driver.

 - ARM Global timer:
	- moved to drivers/clocksource.
	- added revision check in driver.
	- removed unused header file.
	- moved to u64 from union gt_counter
	- comments added in get_counter
	- removed leftover debug code.
	- moved code to use __raw_readl/writel.
	- used DIV_ROUND_CLOSEST
	- added check in interrupt handler.
	- expanded CE and CS acronyms usage.
	- Fixed minimum clock ticks value.
	- move to use clocksource_register_hz
	- added arch sched_clock support.
	- added ERRATA 740657 workaround.

 - ST-System Configuration Registers:
	- moved from syscon usage to st specific driver.

 - ST Pinctrl support:
	- fixed few typos in the documentation.
	- moved some of the retime offset information to driver.
	
 - STixxxx Support:
	- all the SOC support code is moved to mach-stixxxx
	- seperated DEBUG_LL code to new patch.
	- removed unnecessary #interrupt-cells
	- renamed uart to serial
	- moved to multi_v7_defconfig
	- used menuconfig in mach-stixxx/Kconfig
	- removed of_platform_populate as generic code does it for you.
	- scu address is ioremaped.

Thanks,
srini
