v2 cover Add Global Clock controller (GCC) driver for SC7180

[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.

PATCH v2 1/3 clk: qcom: rcg: update the DFS macro for RCG

Update the init data name for each of the dynamic frequency switch controlled clock associated with the RCG clock name, so that it can be generated as per the hardware plan. Thus update the macro accordingly.

PATCH v2 2/3 dt-bindings: clk: qcom: Add YAML schemas for the GCC clock bindings

In reply to Taniya Das

The GCC clock provider have a bunch of generic properties that are needed in a device tree. Add a YAML schemas for those. Also update the compatible for SC7180 along with example for clocks & clock-names.

Re: [PATCH v2 2/3] dt-bindings: clk: qcom: Add YAML schemas for the GCC clock bindings

Hello Rob,

Thank you for your review comments.

Quoted 14 lines · Rob Herring

The GCC clock provider have a bunch of generic properties that are needed in a device tree. Add a YAML schemas for those. Also update the compatible for SC7180 along with example for clocks & clock-names.

You need to remove the old doc.

Would remove it in the next patch.

Don't need a description if there's only 1 entry.

Standard property, you don't need the type here. What's needed is the size.

Would take care of it in the next patch.

Don't need the type (and this would have to be under an 'allOf' to actually work).

PATCH v2 3/3 clk: qcom: Add Global Clock controller (GCC) driver for SC7180

In reply to Taniya Das

Add support for the global clock controller found on SC7180 based devices. This should allow most non-multimedia device drivers to probe and control their clocks.
