2023-03-13clk: qcom: branch: Clean up branch enable registersKonrad Dybcio
Prefix the "branch enable" registers with CBCR_ to be closer to what they are actually called in Qualcomm terms, use GENMASK instead of shifting values around and adjust their usage accordingly.

2023-03-13clk: qcom: branch: Add helper functions for setting SLEEP/WAKE bitsKonrad Dybcio
HLOS-controlled branch clocks on non-ancient Qualcomm platforms feature SLEEP and WAKE fields which can be written to to configure how long the clock hardware should wait internally before being (un)gated. Some very sensitive clocks need to have these values programmed to prevent putting the hardware in a not-exactly-good state. Add definitions of these fields and introduce helpers for setting them inside clock drivers.

2023-03-13clk: qcom: branch: Add helper functions for setting retain bitsKonrad Dybcio
Most Qualcomm branch clocks come with a pretty usual set of bits that can enable memory retention by means of not turning off parts of the memory logic. Add them to the common header file and introduce helper functions for setting them instead of using magic writes.

2019-04-11clk: qcom: branch: Add AON clock opsBjorn Andersson
Some clocks can only be turned on by resetting the block containing them, provide a clock type that allow us to reference these clocks and have the client drivers enable and "disable" them. Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org> Signed-off-by: Stephen Boyd <sboyd@kernel.org>

2018-05-08clk: qcom: Add support for BRANCH_HALT_SKIP flag for branch clocksAmit Nischal
There could be few clocks where the clock status bit is not required to be polled as the clock on/off would be controlled by enabling/disabling external source. Add support for the same by introducing new flag named as 'BRANCH_HALT_SKIP'.
