Philipp Zabel 06445994fe clk: mediatek: make dpi0_sel propagate rate changes
This mux is supposed to select a fitting divider after the PLL
is already set to the correct rate.

James Liao 75ce0cdb62 clk: mediatek: Add MT8173 MMPLL change rate support
MT8173 MMPLL frequency settings are different from common PLLs.
It needs different post divider settings for some ranges of frequency.
This patch add support for MT8173 MMPLL frequency setting by adding
div-rate table to lookup suitable post divider setting under a
specified frequency.

Stephen Boyd c726639bbe clk: mediatek: Properly include clk.h
We don't need to include clk.h in header files, just forward
declare struct clk here. This leads us to a few places where the
include of clk.h was missing in C files. Add them.

Sascha Hauer d633fb7ac1 clk: mediatek: Add reset controller support
The pericfg and infracfg units also provide reset lines to several
other SoC internal units. This adds a function which can be called
from the pericfg and infracfg initialization functions which will
register the reset controller using reset_controller_register. The
reset controller will provide support for resetting the units
connected to the pericfg and infracfg controller. The units resetted
by this controller can use the standard reset device tree binding
to gain access to the reset lines.
