clk: mediatek: Add MT8173 MMPLL change rate support

2015-07-28T18:58:57+00:00

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.

clk: mediatek: Fix calculation of PLL rate settings

2015-07-28T18:58:54+00:00

Avoid u32 overflow when calculate post divider setting, and
increase the max post divider setting from 3 (/8) to 4 (/16).

clk: mediatek: Fix PLL registers setting flow

2015-07-28T18:58:52+00:00

Write postdiv and pcw settings at the same time for PLLs if postdiv
and pcw settings are on the same register.

This is need by PLLs such as MT8173 MMPLL and ARM*PLL.

clk: mediatek: Properly include clk.h

2015-07-20T17:53:09+00:00

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.

clk: mediatek: mt8173: Fix enabling of critical clocks

2015-07-06T22:54:13+00:00

On the MT8173 the clocks are provided by different units. To enable
the critical clocks we must be sure that all parent clocks are already
registered, otherwise the parents of the critical clocks end up being
unused and get disabled later. To find a place where all parents are
registered we try each time after we've registered some clocks if
all known providers are present now and only then we enable the critical
clocks

clk: mediatek: Fix apmixedsys clock registration

2015-06-04T21:07:07+00:00

The size of clk_data should be the same as CLK_APMIXED_NR_CLK
instead of ARRAY_SIZE(plls). CLK_APMIXED_* is numbered from 1, so
CLK_APMIXED_NR_CLK will be greater than ARRAY_SIZE(plls).

clk: mediatek: Initialize clk_init_data

2015-05-20T01:40:48+00:00

The variable init (struct clk_init_data) is allocated on the stack.
We weren't initializing the .flags field, so it contains random junk,
which can cause all kinds of interesting issues when the flags are
parsed by clk_register.
