-Clock bindings for ST-Ericsson U300 System Controller Clocks
-
-Bindings for the gated system controller clocks:
-
-Required properties:
-- compatible: must be "stericsson,u300-syscon-clk"
-- #clock-cells: must be <0>
-- clock-type: specifies the type of clock:
- 0 = slow clock
- 1 = fast clock
- 2 = rest/remaining clock
-- clock-id: specifies the clock in the type range
-
-Optional properties:
-- clocks: parent clock(s)
-
-The available clocks per type are as follows:
-
-Type: ID: Clock:
--------------------
-0 0 Slow peripheral bridge clock
-0 1 UART0 clock
-0 4 GPIO clock
-0 6 RTC clock
-0 7 Application timer clock
-0 8 Access timer clock
-
-1 0 Fast peripheral bridge clock
-1 1 I2C bus 0 clock
-1 2 I2C bus 1 clock
-1 5 MMC interface peripheral (silicon) clock
-1 6 SPI clock
-
-2 3 CPU clock
-2 4 DMA controller clock
-2 5 External Memory Interface (EMIF) clock
-2 6 NAND flask interface clock
-2 8 XGAM graphics engine clock
-2 9 Shared External Memory Interface (SEMI) clock
-2 10 AHB Subsystem Bridge clock
-2 12 Interrupt controller clock

-Example:
-
-gpio_clk: gpio_clk@13M {
- #clock-cells = <0>;
- compatible = "stericsson,u300-syscon-clk";
- clock-type = <0>; /* Slow */
- clock-id = <4>;
- clocks = <&slow_clk>;
-};
-
-gpio: gpio@c0016000 {
- compatible = "stericsson,gpio-coh901";
- (...)
- clocks = <&gpio_clk>;
-};
-
-
-Bindings for the MMC/SD card clock:
-
-Required properties:
-- compatible: must be "stericsson,u300-syscon-mclk"
-- #clock-cells: must be <0>
-
-Optional properties:
-- clocks: parent clock(s)
-
-mmc_mclk: mmc_mclk {
- #clock-cells = <0>;
- compatible = "stericsson,u300-syscon-mclk";
- clocks = <&mmc_pclk>;
-};
-
-mmcsd: mmcsd@c0001000 {
- compatible = "arm,pl18x", "arm,primecell";
- clocks = <&mmc_pclk>, <&mmc_mclk>;
- clock-names = "apb_pclk", "mclk";
- (...)
