[PATCH v2 0/3] Use STM32 access controller for STM32MP25 clocks

[gabriel.fernandez at foss.st.com]

From: Gabriel Fernandez <gabriel.fernandez at foss.st.com>

Use an STM32 access controller to filter the registration of clocks.
Don't register a clock if this clock is secured or declared as shared (this
clock is generally managed by the security world).

This series depends on the stm32_firewall framework (merged since
next-20240419) notably for the include file 'linux/bus/stm32_firewall_device.h'.

Changes in v2:
  - rebased on next-20240514
  - YAML patch was apllied on next
  - use appropriate include
  - manage the case if 'access-contoller' property is not present in the DT
  - rename DT patch (RCC support part was merged)

Gabriel Fernandez (3):
  clk: stm32mp2: use of STM32 access controller
  clk: stm32mp25: add security clocks
  arm64: dts: st: enable STM32 access controller for RCC
