-* Core Clock bindings for Marvell MVEBU SoCs
-
-Marvell MVEBU SoCs usually allow to determine core clock frequencies by
-reading the Sample-At-Reset (SAR) register. The core clock consumer should
-specify the desired clock by having the clock ID in its "clocks" phandle cell.
-
-The following is a list of provided IDs and clock names on Armada 370/XP:
- 0 = tclk (Internal Bus clock)
- 1 = cpuclk (CPU clock)
- 2 = nbclk (L2 Cache clock)
- 3 = hclk (DRAM control clock)
- 4 = dramclk (DDR clock)
-
-The following is a list of provided IDs and clock names on Armada 375:
- 0 = tclk (Internal Bus clock)
- 1 = cpuclk (CPU clock)
- 2 = l2clk (L2 Cache clock)
- 3 = ddrclk (DDR clock)
-
-The following is a list of provided IDs and clock names on Armada 380/385:
- 0 = tclk (Internal Bus clock)
- 1 = cpuclk (CPU clock)
- 2 = l2clk (L2 Cache clock)
- 3 = ddrclk (DDR clock)
-
-The following is a list of provided IDs and clock names on Armada 39x:
- 0 = tclk (Internal Bus clock)
- 1 = cpuclk (CPU clock)
- 2 = nbclk (Coherent Fabric clock)
- 3 = hclk (SDRAM Controller Internal Clock)
- 4 = dclk (SDRAM Interface Clock)
- 5 = refclk (Reference Clock)
-
-The following is a list of provided IDs and clock names on 98dx3236:
- 0 = tclk (Internal Bus clock)
- 1 = cpuclk (CPU clock)
- 2 = ddrclk (DDR clock)
- 3 = mpll (MPLL Clock)
-
-The following is a list of provided IDs and clock names on Kirkwood and Dove:
- 0 = tclk (Internal Bus clock)
- 1 = cpuclk (CPU0 clock)
- 2 = l2clk (L2 Cache clock derived from CPU0 clock)
- 3 = ddrclk (DDR controller clock derived from CPU0 clock)
-
-The following is a list of provided IDs and clock names on Orion5x:
- 0 = tclk (Internal Bus clock)
- 1 = cpuclk (CPU0 clock)
- 2 = ddrclk (DDR controller clock derived from CPU0 clock)
-
-Required properties:
-- compatible : shall be one of the following:
- "marvell,armada-370-core-clock" - For Armada 370 SoC core clocks
- "marvell,armada-375-core-clock" - For Armada 375 SoC core clocks
- "marvell,armada-380-core-clock" - For Armada 380/385 SoC core clocks
- "marvell,armada-390-core-clock" - For Armada 39x SoC core clocks
- "marvell,armada-xp-core-clock" - For Armada XP SoC core clocks
- "marvell,mv98dx3236-core-clock" - For 98dx3236 family SoC core clocks
- "marvell,dove-core-clock" - for Dove SoC core clocks
- "marvell,kirkwood-core-clock" - for Kirkwood SoC (except mv88f6180)
- "marvell,mv88f6180-core-clock" - for Kirkwood MV88f6180 SoC
- "marvell,mv98dx1135-core-clock" - for Kirkwood 98dx1135 SoC
- "marvell,mv88f5181-core-clock" - for Orion MV88F5181 SoC
- "marvell,mv88f5182-core-clock" - for Orion MV88F5182 SoC
- "marvell,mv88f5281-core-clock" - for Orion MV88F5281 SoC
- "marvell,mv88f6183-core-clock" - for Orion MV88F6183 SoC
-- reg : shall be the register address of the Sample-At-Reset (SAR) register
-- #clock-cells : from common clock binding; shall be set to 1
-
-Optional properties:
-- clock-output-names : from common clock binding; allows overwrite default clock
- output names ("tclk", "cpuclk", "l2clk", "ddrclk")
-
-Example:
-
-core_clk: core-clocks@d0214 {
- compatible = "marvell,dove-core-clock";
- reg = <0xd0214 0x4>;
- #clock-cells = <1>;
-};
-
-spi0: spi@10600 {
- compatible = "marvell,orion-spi";
- /* ... */
- /* get tclk from core clock provider */
- clocks = <&core_clk 0>;
-};
