clk: qcom: msm8960: Fix dsi1/2 halt bits

2015-10-27T20:10:13+00:00

The halt bits for these clocks seem wrong. I get the following
warning while booting on an msm8960-cdp:

Fix the status bits and the errors go away.

clk: qcom: mmcc-8960: Add DSI related clocks

2015-10-16T22:08:43+00:00

Add rcg and branch clk structs for DSI1 and DSI2 blocks found in MSM8960
and APQ8064. Each DSI instance has 4 pairs of rcg and branch clocks.
Populate arrays mmcc_msm8960_clks and mmcc_apq8064_clks with these clocks.

clk: qcom: Drop calls to qcom_cc_remove()

2015-10-09T06:53:01+00:00

Now that qcom_cc_remove() is a nop, drop calls to
qcom_cc_remove() and any empty driver remove functions.

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.

clk: qcom: Introduce parent_map tables

2015-03-23T23:09:19+00:00

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.
