-STMicroelectronics STM32 Peripheral Reset Clock Controller
-==========================================================
-
-The RCC IP is both a reset and a clock controller.
-
-RCC makes also power management (resume/supend and wakeup interrupt).
-
-Please also refer to reset.txt for common reset controller binding usage.
-
-Please also refer to clock-bindings.txt for common clock controller
-binding usage.
-
-
-Required properties:
-- compatible: "st,stm32mp1-rcc", "syscon"
-- reg: should be register base and length as documented in the datasheet
-- #clock-cells: 1, device nodes should specify the clock in their
- "clocks" property, containing a phandle to the clock device node,
- an index specifying the clock to use.
-- #reset-cells: Shall be 1
-- interrupts: Should contain a general interrupt line and a interrupt line
- to the wake-up of processor (CSTOP).
-
-Example:
- rcc: rcc@50000000 {
- compatible = "st,stm32mp1-rcc", "syscon";
- reg = <0x50000000 0x1000>;
- #clock-cells = <1>;
- #reset-cells = <1>;
- interrupts = <GIC_SPI 5 IRQ_TYPE_NONE>,
- <GIC_SPI 145 IRQ_TYPE_NONE>;
- };
-
-Specifying clocks
-=================
-
-All available clocks are defined as preprocessor macros in
-dt-bindings/clock/stm32mp1-clks.h header and can be used in device
-tree sources.
-
-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 on STM32MP1, for LTDC reset:
- ltdc = APB4_RSTSETR_offset / 4 * 32 + LTDC_bit_offset
- = 0x180 / 4 * 32 + 0 = 3072
-
-The list of valid indices for STM32MP1 is available in:
-include/dt-bindings/reset-controller/stm32mp1-resets.h
-
-This file implements defines like:
-#define LTDC_R 3072
