Merge branch 'omap/uart' into next/pm 

* omap/uart: (32 commits)
  ARM: omap: pass minimal SoC/board data for UART from dt
  arm/dts: Add minimal device tree support for omap2420 and omap2430
  omap-serial: Add minimal device tree support
  omap-serial: Use default clock speed (48Mhz) if not specified
  omap-serial: Get rid of all pdev->id usage
  ARM: OMAP2+: UART: Fix compilation/sparse warnings
  ARM: OMAP2+: UART: Remove omap_uart_can_sleep and add pm_qos
  ARM: OMAP2+: UART: Do not gate uart clocks if used for debug_prints
  ARM: OMAP2+: UART: Avoid uart idling on suspend for no_console_suspend usecase
  ARM: OMAP2+: UART: Avoid console uart idling during bootup
  ARM: OMAP2+: UART: remove temporary variable used to count uart instance
  ARM: OMAP2+: UART: Make the RX_TIMEOUT for DMA configurable for each UART
  ARM: OMAP2+: UART: Allow UART parameters to be configured from board file.
  ARM: OMAP2+: UART: Remove old and unused clocks handling funcs
  ARM: OMAP2+: UART: Add wakeup mechanism for omap-uarts
  ARM: OMAP2+: UART: Move errata handling from serial.c to omap-serial
  ARM: OMAP2+: UART: Get context loss count to context restore
  ARM: OMAP2+: UART: Remove uart reset function.
  ARM: OMAP2+: UART: Ensure all reg values configured are available from port structure
  ARM: OMAP2+: UART: Remove context_save and move context restore to driver

OMAP UART controller



Required properties:

- compatible : should be "ti,omap2-uart" for OMAP2 controllers

- compatible : should be "ti,omap3-uart" for OMAP3 controllers

- compatible : should be "ti,omap4-uart" for OMAP4 controllers

- ti,hwmods : Must be "uart<n>", n being the instance number (1-based)



Optional properties:

- clock-frequency : frequency of the clock input to the UART
