Series clk: qcom: gcc-sdm845: Swicth from expanded definitions to compact macros | expand

Commit Message

Abel Vesa July 26, 2022, 2:22 p.m. UTC 
Add macros for a visually more compact branch clocks definition,
one for the common branch and one for branch_aon. They differ
from ops point of view, like their name suggest. There are also
three different macros to define the clk.hw.init depending on the
number and type of parent passed on as argument. Also, the macros
added here are only the ones used by gcc-sdm845 driver.
More will be added later on.
