1 | Device Tree Clock bindings for arch-vt8500 | ||
2 | |||
3 | This binding uses the common clock binding[1]. | ||
4 | |||
5 | [1] Documentation/devicetree/bindings/clock/clock-bindings.txt | ||
6 | |||
7 | Required properties: | ||
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 | ||
12 | |||
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. | ||
18 | |||
19 | Required properties for device clocks: | ||
20 | - clocks : shall be the input parent clock phandle for the clock. This should | ||
21 | be a pll output. | ||
22 | - #clock-cells : from common clock binding; shall be set to 0. | ||
23 | |||

25 | Device Clocks | ||
26 | |||
27 | Device clocks are required to have one or both of the following sets of | ||
28 | properties: | ||
29 | |||
30 | |||
31 | Gated device clocks: | ||
32 | |||
33 | Required properties: | ||
34 | - enable-reg : shall be the register offset from PMC base for the enable | ||
35 | register. | ||
36 | - enable-bit : shall be the bit within enable-reg to enable/disable the clock. | ||
37 | |||
38 | |||
39 | Divisor device clocks: | ||
40 | |||
41 | Required property: | ||
42 | - divisor-reg : shall be the register offset from PMC base for the divisor | ||
43 | register. | ||
44 | Optional property: | ||
45 | - divisor-mask : shall be the mask for the divisor register. Defaults to 0x1f | ||
46 | if not specified. | ||
47 | |||
48 | |||
49 | For example: | ||
50 | |||
51 | ref25: ref25M { | ||
52 | #clock-cells = <0>; | ||
53 | compatible = "fixed-clock"; | ||
54 | clock-frequency = <25000000>; | ||
55 | }; | ||
56 | |||
57 | plla: plla { | ||
58 | #clock-cells = <0>; | ||
59 | compatible = "wm,wm8650-pll-clock"; | ||
60 | clocks = <&ref25>; | ||
61 | reg = <0x200>; | ||
62 | }; | ||
63 | |||
64 | sdhc: sdhc { | ||
65 | #clock-cells = <0>; | ||
66 | compatible = "via,vt8500-device-clock"; | ||
67 | clocks = <&pllb>; | ||
68 | divisor-reg = <0x328>; | ||
69 | divisor-mask = <0x3f>; | ||
70 | enable-reg = <0x254>; | ||
71 | enable-bit = <18>; | ||
