this compatible doesn't match with an existing yaml. Can you please add
it maybe in

Can you please move this spi pins group definition in
stm32mp15-pinctrl.dtsi. I see no issue to update existing pin group
nodes in your board file as you do (even if the past I was not in favor
of it but I'm changing :)) but I think that all pins node have to be
defined at the same place to have something consistent about node names:
spi1-0, spi1-1 ...
