Subject: [PATCH 0/4] Use STM32 access controller for STM32MP25 clocks

From: Gabriel Fernandez <gabriel.fernandez@...s.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).
