[PATCH v2 0/2] clk: keystone: Add support for AM64 specific ehrpwm-tbclk

[Lokesh Vutla]

This series adds support for AM64 specific ehrpwm Time-base submodule
clock.

Changes since v1:
- Fixed register offsets and bits for clocks.
- Update the compatible to ti,am64-epwm-tbclk, as high resolution is not
  supported in AM64.

[PATCH v2 2/2] clk: keystone: syscon-clk: Add support for AM64 specific epwm-tbclk

[Lokesh Vutla]

AM64 has 9 instances of EPWM modules. And each instance has a clk to
Timer-Base sub-module that can be controlled by Control module. Update
the driver with all the 9 instance of clocks associated to
ti,am64-epwm-tbclk.

Gentle ping on this series. If there are no objections, can we merge this series.

Thanks and regards,
