There are some YAML issues reported. Some are linked to the 
stm32mp151.dts or common bindings and are going to be fixed. But some 
looks more linked to your board. Can you have a look on those:


arch/arm/boot/dts/stm32mp157c-lxa-tac-gen1.dtb: gpio@24: 
'gpio-line-names' does not match any of the regexes: 'pinctrl-[0-9]+'
	From schema: /Documentation/devicetree/bindings/gpio/gpio-pca9570.yaml

arch/arm/boot/dts/stm32mp157c-lxa-tac-gen1.dtb: display@0: compatible:0: 
'shineworld,lh133k' is not one of ['sainsmart18']
	From schema: 
/Documentation/devicetree/bindings/display/panel/panel-mipi-dbi-spi.yaml

arch/arm/boot/dts/stm32mp157c-lxa-tac-gen1.dtb: display@0: Unevaluated 
properties are not allowed ('compatible', 'spi-3wire' were unexpected)
	From schema: 
/Documentation/devicetree/bindings/display/panel/panel-mipi-dbi-spi.yaml

arch/arm/boot/dts/stm32mp157c-lxa-tac-gen1.dtb: 
/soc/spi@44005000/display@0: failed to match any schema with compatible: 
['shineworld,lh133k', 'panel-mipi-dbi-spi']

/arch/arm/boot/dts/stm32mp157c-lxa-tac-gen1.dtb: switch@0: Unevaluated 
properties are not allowed ('spi-cpha', 'spi-cpol', 'interrupt-parent', 
'interrupts' were unexpected)
	From schema: /Documentation/devicetree/bindings/net/dsa/microchip,ksz.yaml

arch/arm/boot/dts/stm32mp157c-lxa-tac-gen2.dtb: can@4400f000: 
'termination-gpios', 'termination-ohms' do not match any of the regexes: 
'pinctrl-[0-9]+'
	From schema: /Documentation/devicetree/bindings/net/can/bosch,m_can.yaml

Thanks in advance
