Subject: [RESEND PATCH v3 00/11] Introduce STM32MP1 RCC in secured mode

From: Gabriel Fernandez <gabriel.fernandez@...s.st.com>

Platform STM32MP1 can be used in configuration where some clocks and
IP resets can relate as secure resources.
These resources are moved from a RCC clock/reset handle to a SCMI
clock/reset_domain handle.

The RCC clock driver is now dependent of the SCMI driver, then we have
to manage now the probe defering.

v2 -> v3:
  - use determine_rate op instead of round_rate for ck_rtc
  - remove DT patches from patchset to keek Kernel device tree as there are in basic boot.
     We will applied scmi clock phandle thanks dtbo in U-boot.
v1 -> v2:
  - fix yamllint warnings.

Gabriel Fernandez (11):
  clk: stm32mp1: merge 'clk-hsi-div' and 'ck_hsi' into one clock
  clk: stm32mp1: merge 'ck_hse_rtc' and 'ck_rtc' into one clock
  clk: stm32mp1: remove intermediate pll clocks
  clk: stm32mp1: convert to module driver
  clk: stm32mp1: move RCC reset controller into RCC clock driver
  reset: stm32mp1: remove stm32mp1 reset
  dt-bindings: clock: add IDs for SCMI clocks on stm32mp15
  dt-bindings: reset: add IDs for SCMI reset domains on stm32mp15
  dt-bindings: reset: add MCU HOLD BOOT ID for SCMI reset domains on
    stm32mp15
  dt-bindings: clock: stm32mp1 new compatible for secure rcc
  clk: stm32mp1: new compatible for secure RCC support
