[PATCH 0/3] Subject: [PATCH 0/3] clk: stm32mp1: add I2S_CKIN as PLL4 source and keep boot-enabled clocks running

[Gabriel Fernandez]

This series contains three small, independent improvements to the
STM32MP15 clock driver:

 - Patch 1 adds I2S_CKIN to the possible PLL4 reference clocks
   (PLL4SRC = 3).

 - Patch 2 makes pll_disable() keep PLLON set while one of the DIVPEN,
   DIVQEN or DIVREN bits is set. A P/Q/R output enabled by an earlier
   boot stage and not yet claimed by its consumer is unknown to the
   clock framework. Enabling and then disabling another output of the
   same PLL would otherwise switch the PLL off and cut that output.

- Patch 3 adds CLK_IGNORE_UNUSED to ck_trace, as already done for
   ck_sys_dbg, so that a trace session set up by the bootloader or a
   debugger is not stopped at the end of the boot.
