[PATCH v2 0/3] stm32mp: prepare RCC support for STM32MP13

[Patrick Delaunay]

Prepare the support of STM32MP13 RCC, the reset and clock controller
- update of the RCC MISC driver to bind the correct clock and reset driver
- reset driver, same than STM32MP15x = drivers/reset/stm32-reset.c
- clock driver, add a stm32 sub directory to prepare the addition of
  stm32mp13 drivers named "stm32mp13_clk";
  the stm32mp1 driver is only required for STM32MP15x family
- Add RCC node in SOC device tree with the needed tag
  u-boot,dm-pre-reloc property

This serie is only a preliminary step for STM32MP13 clock and reset support
in U-Boot, based on Linux kernel binding [1];
It prepares the next device tree alignment with Linux kernel and simplify
the review of the serie with addition of STMP13 clock driver based on CCF
and on SCMI clocks provided by OP-TEE, with files
- drivers/clk/stm32/clk-stm32mp13.c
- drivers/clk/stm32/clk-stm32-core.c

In the V2, I remove the addition of a dummy stm32mp13 clock driver:
  [2/4] clk: stm32mp13: add a STM32MP13 RCC clock driver
