[PATCH 00/13 v2] OMAP: Serial: Add omap-serial driver with platform support

[PATCH 00/13 v2] OMAP: Serial: Add omap-serial driver with platform support

[Govindraj.R]

This patch series adds a serial driver to handle uarts on omap platforms.
Currenlty omap-uarts are handled with 8250 driver, since updating
this driver with omap specific features will over load
the 8250 driver with all omap-specific data thus a new driver
is added to configure and support features like
dma, h/w, s/w flowcontrol for omap-uarts.
Also the patch series updates various low level platform specific
serial data to support omap-uarts with hwmod framework and adds support
for uart4 on OMAP3630.

v1 to v2 changes:
----------------
1) Incorporate timeout check

2) Add wk_st, padconf etc for uart4

Benoit Cousson (1):
  OMAP4: UART: Add uart1-4 hwmods data for omap4

Govindraj.R (8):
  OMAP2: UART: remove set_uart_globals.
  OMAP clock: Add uart4_ick/fck definitions for 3630
  OMAP3: PRCM: Consider UART4 for 3630 chip in prcm_setup_regs
  OMAP3: PM: Add prepare idle and resume idle call for uart4
  OMAP3: serial: Fix uart4 handling for 3630
  serial: Add OMAP high-speed UART driver
  OMAP: SERIAL: Enable omap-serial driver in Kconfig.
  OMAP3: SERIAL: Initialize all omap-uarts for zoom boards

Kevin Hilman (4):
  OMAP2/3: UART: add omap_hwmod data for UARTs 1-4
  OMAP: UART: omap_device converions, remove implicit 8520 assumptions
  OMAP: UART: don't do automatic bus-level suspend/resume
  OMAP: UART: use non-locking versions of hwmod enable/idle functions

3) All UARTs initialized for Zoom2/3

Also, please report platforms this was tested on, and what was tested.
You need to validate retention and off-mode during idle and suspend, as
well as enabling/disabling the UART sleep_timeout values via sysfs.

Thanks,

Kevin
