-STMicroelectronics STM32H7 Reset and Clock Controller
-=====================================================
-
-The RCC IP is both a reset and a clock controller.
-
-Please refer to clock-bindings.txt for common clock controller binding usage.
-Please also refer to reset.txt for common reset controller binding usage.
-
-Required properties:
-- compatible: Should be:
- "st,stm32h743-rcc"
-
-- reg: should be register base and length as documented in the
- datasheet
-
-- #reset-cells: 1, see below
-
-- #clock-cells : from common clock binding; shall be set to 1
-
-- clocks: External oscillator clock phandle
- - high speed external clock signal (HSE)
- - low speed external clock signal (LSE)
- - external I2S clock (I2S_CKIN)
-
-Optional properties:
-- st,syscfg: phandle for pwrcfg, mandatory to disable/enable backup domain
- write protection (RTC clock).
-
-Example:
-
- rcc: reset-clock-controller at 58024400 {
- compatible = "st,stm32h743-rcc", "st,stm32-rcc";
- reg = <0x58024400 0x400>;
- #reset-cells = <1>;
- #clock-cells = <1>;
- clocks = <&clk_hse>, <&clk_lse>, <&clk_i2s_ckin>;
-
- st,syscfg = <&pwrcfg>;
-};
-
-The peripheral clock consumer should specify the desired clock by
-having the clock ID in its "clocks" phandle cell.
-
-Example:
-
- timer5: timer at 40000c00 {
- compatible = "st,stm32-timer";
- reg = <0x40000c00 0x400>;
- interrupts = <50>;
- clocks = <&rcc TIM5_CK>;
- };
-
-Specifying softreset control of devices
-=======================================
-
-Device nodes should specify the reset channel required in their "resets"
-property, containing a phandle to the reset device node and an index specifying
-which channel to use.
-The index is the bit number within the RCC registers bank, starting from RCC
-base address.
-It is calculated as: index = register_offset / 4 * 32 + bit_offset.
-Where bit_offset is the bit offset within the register.
-
-For example, for CRC reset:
- crc = AHB4RSTR_offset / 4 * 32 + CRCRST_bit_offset = 0x88 / 4 * 32 + 19 = 1107
-
-Example:
-
- timer2 {
- resets = <&rcc STM32H7_APB1L_RESET(TIM2)>;
- };
