clk: qcom: Fix parent_map translations

2015-04-08T18:07:38+00:00

When we introduced the parent_map tables, we missed to update
some of the functions where mapping is translated. Fix this.

clk: qcom: Add EBI2 clocks for IPQ806x

2015-04-06T21:07:49+00:00

The NAND controller within EBI2 requires EBI2_CLK and
EBI2_ALWAYS_ON_CLK clocks.  Create structs for these clocks so
that they can be used by the NAND controller driver. Add an entry
for EBI2_AON_CLK in the gcc-ipq806x DT binding document.

clk: qcom: Fix ipq806x LCC frequency tables

2015-03-27T05:43:30+00:00

These frequency tables list the wrong rates. Either they don't
have the correct frequency at all, or they're specified in kHz
instead of Hz. Fix it.

clk: qcom: Add MSM8916 Global Clock Controller support

2015-03-23T23:09:22+00:00

This patch adds support for the global clock controller found on the MSM8916
based devices. It allows the various device drivers to probe and control
their clocks and resets.

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.

clk: qcom: Do some error handling in configure_bank()

2015-03-23T23:09:18+00:00

Currently configure_bank() returns void. Add some error
checking on the regmap calls and propagate if there is
any error.
