[PATCH v4 0/6] clk/exynos5250: add clocks for hdmi subsystem

[PATCH v4 0/6] clk/exynos5250: add clocks for hdmi subsystem

[Rahul Sharma]

Add clock changes for hdmi subsystem for exynos5250 SoC. These
include addition of new clocks like mout_hdmi and smmu_tv, associating
ID to clk_hdmiphy and some essential corrections.

This set is based on kukjin's for-next branch at
http://git.kernel.org/cgit/linux/kernel/git/kgene/linux-samsung.git.

V4:
1) Added Arun's patch hdmi clock number correction in this series.
2) Corrected clock number for smmu_mixer

V3:
1) Rebase to kgene for-next based on 3.11-rc1.
2) Added Tushar's patch in the series.

V2:
1) Dropped "clk/exynos5250: Fix HDMI clock number in documentation" as
it already get merged.

[PATCH v4 3/6] clk/exynos5250: add mout_hdmi mux clock for hdmi

[Rahul Sharma]

hdmi driver needs to change the parent of hdmi clock
frequently between pixel clock and hdmiphy clock. hdmiphy is
not stable after power on and for a short interval while changing
the phy configuration. For this duration pixel clock is used to
clock hdmi.

This patch is exposing the mux for changing parent.

[PATCH v4 5/6] clk/exynos5250: add clock for mixer sysmmu

[Rahul Sharma]

Adding sysmmu clock for mixer for exynos5250 SoC. It also
adds aclk200_disp1 mux which is the real parent of the
disp1 block (contains hdmi, mixer, sysmmu_mixer).

[PATCH v4 6/6] clk/exynos5250: change parent to aclk200_disp1 for hdmi subsystem

[Rahul Sharma]

parent of hdmi and mixer block is mentioned as aclk200 which is
not correct. It is clocked by the ouput of aclk200_disp1. Hence
parent for mixer and hdmi clocks is changed to aclk200_disp1.

You can drop this patch as it is fixed in the clk-next branch already by

I've taken patches 2-4 into the clk-next branch. Patch #1 can be
dropped.

Patches 5 & 6 need to be rebased onto clk-next as the g2d clock has
reserved mapping 345.  Also I've cc'd Cho KyongHo who is rebasing his
system mmu clock patch[1] onto clk-next. Can the two of your coordinate
your changes to avoid mapping conflicts in the binding? Perhaps Rahul
can carry Cho's patch in his next version when he rebases patches 5 & 6.

Thanks,
Mike
