1 Device Tree Clock bindings for arch-vt8500
3 This binding uses the common clock binding[1].
5 [1] Documentation/devicetree/bindings/clock/clock-bindings.txt
8 - compatible : shall be one of the following:
9 "via,vt8500-pll-clock" - for a VT8500/WM8505 PLL clock
10 "wm,wm8650-pll-clock" - for a WM8650 PLL clock
11 "via,vt8500-device-clock" - for a VT/WM device clock
13 Required properties for PLL clocks:
14 - reg : shall be the control register offset from PMC base for the pll clock.
15 - clocks : shall be the input parent clock phandle for the clock. This should
16 be the reference clock.
17 - #clock-cells : from common clock binding; shall be set to 0.
19 Required properties for device clocks:
20 - clocks : shall be the input parent clock phandle for the clock. This should
22 - #clock-cells : from common clock binding; shall be set to 0.
27 Device clocks are required to have one or both of the following sets of
34 - enable-reg : shall be the register offset from PMC base for the enable
36 - enable-bit : shall be the bit within enable-reg to enable/disable the clock.
39 Divisor device clocks:
42 - divisor-reg : shall be the register offset from PMC base for the divisor
45 - divisor-mask : shall be the mask for the divisor register. Defaults to 0x1f
