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 "wm,wm8750-pll-clock" - for a WM8750 PLL clock
12 "wm,wm8850-pll-clock" - for a WM8850 PLL clock
13 "via,vt8500-device-clock" - for a VT/WM device clock
15 Required properties for PLL clocks:
16 - reg : shall be the control register offset from PMC base for the pll clock.
17 - clocks : shall be the input parent clock phandle for the clock. This should
18 be the reference clock.
19 - #clock-cells : from common clock binding; shall be set to 0.
21 Required properties for device clocks:
22 - clocks : shall be the input parent clock phandle for the clock. This should
24 - #clock-cells : from common clock binding; shall be set to 0.
29 Device clocks are required to have one or both of the following sets of
36 - enable-reg : shall be the register offset from PMC base for the enable
38 - enable-bit : shall be the bit within enable-reg to enable/disable the clock.
41 Divisor device clocks:
44 - divisor-reg : shall be the register offset from PMC base for the divisor
47 - divisor-mask : shall be the mask for the divisor register. Defaults to 0x1f
