062ee99e0a clk: stm32mp1: Add support for USART1 clock
Add USART1 clock parents and mux configuration. This allows
support for configuring the USART1 as the serial console in
SPL and U-Boot via device tree. Without this patch the SPL
with usart1 serial console enabled crashes because it can
not find the clock specified in the device tree for usart1.

141e232dbd clk: stm32mp1: remove error for disabled clock in stm32mp1_clk_get_parent
To disabled a clock in clock tree initialization for a mux of STM32MP15,
the selected clock source index is set with the latest possible index for
the number of bit used. Today this valid configuration cause a error
in U-Boot messages, for example with CLK_ETH_DISABLED, when this clock
is not needed for the used ETH PHY without crystal:

   no parents defined for clk id 123

This patch change the level of this message to avoid this trace for
valid clock tree.

c8df960c8d clk: stm32mp13: introduce STM32MP13 RCC driver
STM32MP13 RCC driver uses Common Clock Framework and also a
'clk-stm32-core' API. Then STM32MPx RCC driver will contain only data
configuration (gates, mux, dividers and the way to check security)
or some specific clocks.
This API will be used by all new other generations of ST Socs.

b99293338e clk: Add directory for STM32 clock drivers
Add a directory in drivers/clk to regroup the clock drivers for all
STM32 Soc with CONFIG_ARCH_STM32 (MCUs with cortex M) or
CONFIG_ARCH_STM32MP (MPUs with cortex A).
