    clk: Add driver for Palmas clk32kg and clk32kgaudio clocks · 942d1d67
    Peter Ujfalusi authored
    Palmas class of devices can provide 32K clock(s) to be used by other devices
    on the board. Depending on the actual device the provided clocks can be:
    CLK32K_KG and CLK32K_KGAUDIO
    or only one:
    CLK32K_KG (TPS659039 for example)
    
    Use separate compatible flags for the two 32K clock.
    A system which needs or have only one of the 32k clock from
    Palmas will need to add node(s) for each clock as separate section
    in the dts file.
    The two compatible property is:
    "ti,palmas-clk32kg" for clk32kg clock
    "ti,palmas-clk32kgaudio" for clk32kgaudio clock
    
    Apart from the register control of the clocks - which is done via
    the clock API there is a posibility to enable the external sleep
    control. In this way the clock can be enabled/disabled on demand by the
    user of the clock.
    
    See the documentation for more details.
