ac269395cd clk: qcom: Convert to clk_hw based provider APIs
We're removing struct clk from the clk provider API, so switch
this code to using the clk_hw based provider APIs.

293d2e97b3 clk: qcom: Introduce parent_map tables
In the current parent mapping code, we can get duplicate or inconsistent
indexes, which leads to discrepancy between the number of elements in the
array and the number of parents. Until now, this was solved with some
reordering but this is not always possible.

This patch introduces index tables that are used to define the relations
between the PLL source and the hardware mux configuration value.
To accomplish this, here we do the following:
 - Define a parent_map struct to map the relations between PLL source index
 and register configuration value.
 - Add a qcom_find_src_index() function for finding the index of a clock
 matching the specific PLL configuration.
 - Update the {set,get}_parent RCG functions use the newly introduced
 parent_map struct.
 - Convert all existing drivers to the new parent_map tables.

59c0621d4d clk: Remove .owner field for driver
There is no need to init .owner field.

Based on the patch from Peter Griffin <peter.griffin@linaro.org>
"mmc: remove .owner field for drivers using module_platform_driver"

This patch removes the superflous .owner field for drivers which
use the module_platform_driver API, as this is overriden in
platform_driver_register anyway."

229fd4a505 clk: qcom: Add support for banked MD RCGs
The banked MD RCGs in global clock control have a different
register layout than the ones implemented in multimedia clock
control. Add support for these types of clocks so we can change
the rates of the UBI32 clocks.

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.

e216ce60a9 clk: qcom: Add support for APQ8064 multimedia clocks
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.

f87dfcabc6 clk: qcom: mdp_lut_clk is a child of mdp_src
The mdp_lut_clk isn't a child of the mdp_clk. Instead it's the
child of the mdp_src clock. Fix it.

ff20783f7b clk: qcom: Fix MN frequency tables, parent map, and jpegd
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.

404c1ff67d clk: qcom: Support bypass RCG configuration
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.
