Damlogic,axg-audio-clkc.txt1 * Amlogic AXG Audio Clock Controllers
3 The Amlogic AXG audio clock controller generates and supplies clock to the
4 other elements of the audio subsystem, such as fifos, i2s, spdif and pdm
9 - compatible : should be "amlogic,axg-audio-clkc" for the A113X and A113D,
10 "amlogic,g12a-audio-clkc" for G12A,
11 "amlogic,sm1-audio-clkc" for S905X3.
12 - reg : physical base address of the clock controller and length of
14 - clocks : a list of phandle + clock-specifier pairs for the clocks listed
15 in clock-names.
16 - clock-names : must contain the following:
