clk: qcom: Fix sdc 144kHz frequency entry

2014-09-02T23:52:28+00:00

The pre-divider for the sdc clocks only has 2 bits in it, so we
can't possibly divide by anything larger than 4 here.
Furthermore, we program the value of ~(n - m) and the n value is
larger than 8 bits (max of 256). Replace this entry with 200kHz
which is close enough to 144kHz to be usable.

Merge tag 'qcom-clocks-for-3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/galak/linux-qcom into clk-next-msm

qcom clock changes for 3.17

These patches add support for a handful of Qualcomm's SoC clock
controllers: APQ8084 gcc and mmcc, IPQ8064 gcc, and APQ8064.
There's also a small collection of bug fixes that aren't critical
-rc worthy regressions because the consumer drivers aren't present
or using the buggy clocks and one optimization for HDMI.

clk: qcom: Add support for APQ8064 multimedia clocks

2014-07-15T23:39:03+00:00

The APQ8064 multimedia clock controller is fairly similar to the
8960 multimedia clock controller, except that gfx2d0/1 has been
removed and the gfx3d frequency is slightly faster when using the
newly introduced PLL15. We also add vcap clocks and a couple new
TV clocks.

clk: qcom: pll: Add support for configuring SR PLLs

2014-07-15T23:39:02+00:00

Some SR type PLLs need to be configured for a certain rate when
linux boots. Add support for these types of PLLs so that we can
program PLL15's rate on apq8064.

clk: qcom: mdp_lut_clk is a child of mdp_src

2014-07-15T23:39:01+00:00

The mdp_lut_clk isn't a child of the mdp_clk. Instead it's the
child of the mdp_src clock. Fix it.

clk: qcom: Fix PLL rate configurations

2014-07-15T23:39:00+00:00

Sometimes we need to program PLLs with a fixed rate
configuration during driver probe. Doing this after we register
the PLLs with the clock framework causes the common clock
framework to assume the rate of the PLLs are 0. This causes all
sorts of problems for rate recalculations because the common
clock framework caches the rate once at registration time unless
a flag is set to always recalculate the rates.

Split the qcom_cc_probe() function into two pieces, map and
everything else, so that drivers which need to configure some
PLL rates or otherwise twiddle bits in the clock controller can
do so before registering clocks. This allows us to properly
detect the rates of PLLs that are programmed at boot.

clk: qcom: Fix MN frequency tables, parent map, and jpegd

2014-07-15T23:39:00+00:00

Clocks that don't have a pre-divider don't list any pre-divider
in their frequency tables, but their tables are initialized using
aggregate initializers. Use tagged initializers so we properly
assign the m and n values for each frequency. Furthermore, the
mmcc_pxo_pll8_pll2_pll3 array improperly mapped the second
element to pll2 instead of pll8, causing the clock driver to
recalculate the wrong rate for any clocks using this array along
with a rate that uses pll2. Plus the .num_parents field is 3
instead of 4 so you can't even switch the parent to pll3. Finally
I noticed that the jpegd clock improperly indicates that the
pre-divider width is only 2, when it's actually 4 bits wide.

clk: qcom: Support bypass RCG configuration

2014-07-15T23:38:59+00:00

In the case of HDMI clocks, we want to bypass the RCG's ability
to divide the output clock and pass through the parent HDMI PLL
rate. Add a simple set of clk_ops to configure the RCG to do
this. This removes the need to keep adding more frequency entries
to the tv_src clock whenever we want to support a new rate.

clk: qcom: Add support for IPQ8064's global clock controller (GCC)

2014-07-15T23:38:58+00:00

Add a driver for the global clock controller found on IPQ8064 based
platforms. This should allow most non-multimedia device drivers to probe
and control their clocks.

This is currently missing clocks for USB HSIC and networking devices.
