Subject: OMAPDSS: HDMI: use common DSS PLL support
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c84c3a5bb78ff271787a1fec9218768aed555e8d;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

OMAPDSS: HDMI: use common DSS PLL support

Now that we have the common DSS PLL support, change HDMI to use it. This
results in quite a lot of changes, but almost all of them are trivial
name changes.

The function to program the PLL settings can be removed from hdmi_pll.c,
as the common PLL API contains the same functionality.
