[PATCH v5 01/10] clk: qcom: branch: Add helper functions for setting retain bits

[PATCH v5 01/10] clk: qcom: branch: Add helper functions for setting retain bits

[Konrad 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.

[PATCH v5 02/10] clk: qcom: branch: Add helper functions for setting SLEEP/WAKE bits

[Konrad 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.

[PATCH v5 04/10] clk: qcom: branch: Clean up branch enable registers

[Konrad 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.
