[PATCH v7 00/15] ARM: mxs: Add initial support for MX23 and MX28

[Shawn Guo]

Changes for v7 of this patch series:
 - Use clocksource_register_hz
 - Add mxs namespace for the missing ones
 - Use CLKCTRL_RESET_CHIP over RTC_WATCHDOG to implement arch_reset
 - Define naked pad and introduce validity bits for mA/vol/pull
   to ease the pad modification
 - List all pad definitions at once generated from Freescale
   pinmux Excel sheet
 - Add more comments for timrot instance used for MX23 and MX28
 - Use HW_TIMROT_TIMCOUNTn for v1 to avoid confusion
 - Detect timrot version by reading register HW_TIMROT_VERSION
 - Switch over to use gpiolib __gpio_to_irq()
 - Fix some checkpatch warnings
