[PATCH v2 0/4] ARM: OMAP2+: dmtimer: cleanup related to devm API and clk usage

[Tarun Kanti DebBarma]

The devm API usage in probe() simplifies error handling operation.
Since iclk is not used in the driver it is removed from wherever
not needed.
Corrected the timer fck name mis-match between clock44xx_data.c and
omap_hwmod_44xx_data.c.
Added omap_hwmod_get_main_clk() API. There is no more need to construct
clock names using sprintf() to be used in clk_get() during initialization.

Commit: e816b57a337ea3b755de72bec38c10c864f23015 (Linux 3.4-rc3)

Series is available here for reference:
git://gitorious.org/~tarunkanti/omap-sw-develoment/tarunkantis-linux-omap-dev dmtimer_cleanup_for_3.5

Tested on following platforms:
OMAP5, OMAP4430SDP, OMAP3430SDP, OMAP2430SDP.
Could not test on OMAP2420 due to unavailability of board.

v2:
- Use devm_request_and_ioremap() instead of request_mem_region() and ioremap()
- Add omap_hwmod_get_main_clk() API
- Reverted changes of clock names from OMAP2 and OMAP3 platforms
