Convert Amlogic AXG Audio Clock Controller binding to yaml. Signed-off-by: Alexander Stein <alexander.stein@xxxxxxxxxxx> --- As it is the same directory I picked the same maintainers as Documentation/devicetree/bindings/clock/amlogic,a1-peripherals-clkc.yaml. I'm not 100% sure about the optional clocks constraints. As mentioned in the .txt version only pclk is mandatory, others are optional. .../bindings/clock/amlogic,axg-audio-clkc.txt | 59 -------- .../clock/amlogic,axg-audio-clkc.yaml | 136 ++++++++++++++++++ 2 files changed, 136 insertions(+), 59 deletions(-) delete mode 100644 Documentation/devicetree/bindings/clock/amlogic,axg-audio-clkc.txt create mode 100644 Documentation/devicetree/bindings/clock/amlogic,axg-audio-clkc.yaml diff --git a/Documentation/devicetree/bindings/clock/amlogic,axg-audio-clkc.txt b/Documentation/devicetree/bindings/clock/amlogic,axg-audio-clkc.txt deleted file mode 100644 index 3a8948c04bc9..000000000000 --- a/Documentation/devicetree/bindings/clock/amlogic,axg-audio-clkc.txt +++ /dev/null @@ -1,59 +0,0 @@ -* Amlogic AXG Audio Clock Controllers - -The Amlogic AXG audio clock controller generates and supplies clock to the -other elements of the audio subsystem, such as fifos, i2s, spdif and pdm -devices. - -Required Properties: - -- compatible : should be "amlogic,axg-audio-clkc" for the A113X and A113D, - "amlogic,g12a-audio-clkc" for G12A, - "amlogic,sm1-audio-clkc" for S905X3. -- reg : physical base address of the clock controller and length of - memory mapped region. -- clocks : a list of phandle + clock-specifier pairs for the clocks listed - in clock-names. -- clock-names : must contain the following: - * "pclk" - Main peripheral bus clock - may contain the following: - * "mst_in[0-7]" - 8 input plls to generate clock signals - * "slv_sclk[0-9]" - 10 slave bit clocks provided by external - components. - * "slv_lrclk[0-9]" - 10 slave sample clocks provided by external - components. -- resets : phandle of the internal reset line -- #clock-cells : should be 1. -- #reset-cells : should be 1 on the g12a (and following) soc family - -Each clock is assigned an identifier and client nodes can use this identifier -to specify the clock which they consume.
