Subject: [PATCH] ARM: lpc3250: fix uda1380 gpio numbers
Date: Wed, 10 Jan 2018 17:22:00 +0100 [thread overview]
Message-ID: <20180110162220.224945-1-arnd@arndb.de> (raw)
dtc warns about obviously incorrect GPIO numbers for the audio codec
on both lpc32xx boards:
arch/arm/boot/dts/lpc3250-phy3250.dtb: Warning (gpios_property): reset-gpio property size (12) too small for cell size 3 in /ahb/apb/i2c at 400A0000/uda1380 at 18
arch/arm/boot/dts/lpc3250-phy3250.dtb: Warning (gpios_property): power-gpio property size (12) too small for cell size 3 in /ahb/apb/i2c at 400A0000/uda1380 at 18
arch/arm/boot/dts/lpc3250-ea3250.dtb: Warning (gpios_property): reset-gpio property size (12) too small for cell size 3 in /ahb/apb/i2c at 400A0000/uda1380 at 18

It looks like the nodes are written for a different binding that combines
the GPIO number into a single number rather than a bank/number pair.
I found the right numbers on stackexchange.com, so this patch fixes
the warning and has a reasonable chance of getting things to actually
work.
