Subject: [PATCH v4 0/5] Add Global Clock controller (GCC) driver for SC7180

[v4]
  * convert current documentation to YAML schemas.
  * Update license to use GPL-2.0-only.
  * define nvmem-cells/nvmem-cell-names only for the required compatible.
  * split the dt-bindings for SC7180 to a separate patch.
  * remove registering the CRITICAL clocks to clock provider and leave them
    always ON from the GCC probe.
  * Return NULL from qcom_cc_clk_hw_get where clk hw is not registered.
  * gcc_sc7180_init moved from subsys to core init.

[v3]
  * Remove old documentation and fix comments for binding.
  * Cleanup few CRITICAL clocks and add comments for the CRITICAL clocks.
  * Add reference clocks for UFS & USB.

[v2]
 * Update the DFS macro for RCG to reflect the hw init similar to clock
   name.
 * Update the Documentation binding of GCC to YAML schemas.
 * Add comments for CRITICAL clocks, remove PLL forward declarations and
   unwanted comments/prints.

[v1]
  * Add driver support for Global Clock controller for SC7180 and also
    update device tree bindings for the various clocks supported in the
    clock controller.

Taniya Das (5):
  clk: qcom: rcg: update the DFS macro for RCG
  clk: qcom: common: Return NULL from clk_hw OF provider
  dt-bindings: clock: Add YAML schemas for the QCOM GCC clock bindings
  dt-bindings: clock: Introduce QCOM GCC clock bindings
  clk: qcom: Add Global Clock controller (GCC) driver for SC7180
