This is snapshot of the clock framework files as of msm-4.9
'commit cc7a1542d987 ("msm: ipa: Fix assignment warning with clang").
Below is the brief description of the additional changes made:
1. Add COMMON_CLK_MSM config flag for conditional compilation for
some common files used between COMMON_CLK_MSM and COMMON_CLK_QCOM
clock framework files.
2. Add reset controller framework files for BCR operation.
3. Add conditional compilation support for FTRACE clock functions
to maintain compatibility for clock framework based on
COMMON_CLK_MSM and COMMON_CLK_QCOM.
4. Add files for GDSC operation.
5. Add BCR reset maps.
6. Resolve compilation issue for qti-quin-gvm.
Some PLL HWs require an additional delay for the PLL lock detect
to stabilize after being brought out of reset and SW to poll for
lock detect status. Add delay of 50uSec before polling lock_det
bit by introducing new pll ops.
Also if PLL fails to lock, record additional PLL debug information
in the kernel log before panic().
'commit 90cb5ecd7cfd ("clk: msm: Add delay of 50uSec before polling
lock_detect status")'.
1:1 is the MN divider preference for DSI PCLK for the regular
24 bpp use-case for display as per hardware recommendation.
Update the divider array to give first priority to 1:1
divider combination.
'commit a270c07a1e21 ("clk: msm: update the fractional divider
array for DSI PCLK")'.
For some PLLs, there could be need to configure the calibration
L value for auto calibration which PLL would use whenever it will
come out of reset. Add support for the same by writing into
USER_CTL_HI register.
'commit 05bd8759e347 ("clk: msm: Add support to configure
calibration L value")'.
