[PATCH v2 0/2] Add Global Clock controller (GCC) driver for SC7280

[PATCH v2 0/2] Add Global Clock controller (GCC) driver for SC7280

[Taniya Das]

Add driver support for Global Clock controller for SC7280 and also update
device tree bindings for the various clocks supported in the clock controller.

[v2]
 * Add UFS phy rx/tx symbol clocks in bindings.
 * Remove protected-clocks node & description.
 * Add support for extra clocks for QSPI/WPSS/MSS/LPASS/PCIE clocks.
 * Update the floor rcg ops for SDCC/QSPI clock.
 * Add comment for cpuss critical clocks.

[v1]
 * Documentation binding for GCC clock for SC7280.
 * GCC clock driver for SC7280.
