I would apply this but there are some warnings like:

/home/claudiu/repos/linux-microchip/arch/arm/boot/dts/microchip/at91-sama5d29_curiosity.dtb:
leds: 'blue', 'green', 'red' do not match any of the regexes:
'(^led-[0-9a-f]$|led)', 'pinctrl-[0-9]+'

/home/claudiu/repos/linux-microchip/arch/arm/boot/dts/microchip/at91-sama5d29_curiosity.dtb:
pinctrl@...38000: i2c0-gpio: {'pinmux': [[63, 64]], 'bias-disable': True,
'phandle': [[23]]} is not of type 'array'
        from schema $id:
http://devicetree.org/schemas/gpio/gpio-consumer.yaml#
/home/claudiu/repos/linux-microchip/arch/arm/boot/dts/microchip/at91-sama5d29_curiosity.dtb:
pinctrl@...38000: i2c1-gpio: {'pinmux': [[100, 101]], 'bias-disable': True,
'phandle': [[36]]} is not of type 'array'

Can you, please, run make dtbs_check arch/arm/boot/dts/microchip and fix
the warnings introduced by your dts (not the ones comming from dtsi at the
moment)?

Thank you,
Claudiu Beznea
