This change introduces stm32l5xx clock definitions and separates it from L4xx series. This change comes because of CCIPR missmatch of SAI between L4xx and L5xx series. Signed-off-by: Mario Paja <[email protected]>
This change introduces PLLSAI1 and SAI1 A/B nodes to STM32L5xx series Signed-off-by: Mario Paja <[email protected]>
STM32L5xx series shares several DMA configurations with the other platforms. These changes aim to enable platform specific DMA configuration and align them to other platforms. Signed-off-by: Mario Paja <[email protected]>

This PR enables SAI on STM32L5xx series by:
stm32l5_clockdt-binding due to diffrences with L4xx seriesSAI1 A/Bnodes &PLLSAI1samples/drivers/i2s/outputInformation:
Talking directly to DMA instances (Instead of using DMAMUX) is the only possible solution (today) for drivers implemented using HAL.
Example
Audio: 16bit, 2CH, 44.1KHz, using PCM5102A
