clk: keystone: syscon-clk: Enable audio reference clock
|
expand
|
TI's AM62 SoC can optionally provide two audio reference clocks (AUDIO_REFCLKx) to external peripherals. By default the reference clock is looped-back inside the SoC to a mux that goes to McASP AHCLK, but can optionally be enabled as an output to peripherals outside the SoC by setting a bit through the syscon (CTRL_MMR) registers. This patch series extends the existing syscon-clk driver to support the audio reference clock, and also adds new device tree bindings documentation.
