This patchset adds clkdev based clock lookup support and device tree based
discovery for Samsung uart controller driver. Passing of clock names in
platform data is removed.
In the process of adding these features, other changes have also been made
that merges all the SoC specfic extensions into the parent driver.
This patch has been tested with a following addtional macro suggested by
Russell King (<rmk+kernel@xxxxxxxxxxxxxxxx>) but this macro is not
included in this patch nor is it available in any tree yet. There is a
seperate work going on to prepare a patch series that consolidates
the macros used to instantiate a 'struct clk_lookup'. This patchset
would use that work when it is submitted.

This patchset is based on the following tree
https://github.com/kgene/linux-samsung.git branch: for-next
with the following two patches applied
[PATCH] serial: samsung: Add unified interrupt handler for s3c64xx and later SoC's
[PATCH] ARM: SAMSUNG: Remove uart irq handling from plaform code
and tested on the following boards.
SMDK2440, SMDK2416, SMDK6410, SMDK6440, SMDK6450, SMDKC100, SMDKV210, SMDKV310.
Thomas Abraham (9):
serial: samsung: Keep a copy of the location of platform data in driver's private data
serial: samsung: move handling of fclk/n clock to platform code
serial: samsung: switch to clkdev based clock lookup
serial: samsung: remove struct 's3c24xx_uart_clksrc' and all uses of it
serial: samsung: remove all uses of get_clksrc and set_clksrc
arm: samsung: register uart clocks to clock lookup list
