Subject: ARM: dts: am335x-sl50: Fix cannot claim requested pins for spi0
From: Enric Balletbo i Serra <[email protected]>
commit db145db99f5bf30acc12d7450b9ad0707072a7be upstream.
We don't need to bitbang these pins anymore, instead we muxed these pins as SPI, after this change, done in commit 6c69f726, we introduced the following error:
pinctrl-single 44e10800.pinmux: pin PIN85 already requested \
by 44e10800.pinmux; cannot claim for 48030000.spi pinctrl-single 44e10800.pinmux: pin-85 (48030000.spi) status -22
