Subject: [PATCH] ARM: dts: imx27-phytec-phycard-s-rdk: Fix the I2C1 pinctrl entries
Date: Fri, 27 Mar 2020 10:36:24 -0300	[thread overview]
Message-ID: <20200327133624.26160-1-festevam@gmail.com> (raw)

The I2C2 pins are already used and the following errors are seen:

imx27-pinctrl 10015000.iomuxc: pin MX27_PAD_I2C2_SDA already requested by 10012000.i2c; cannot claim for 1001d000.i2c
imx27-pinctrl 10015000.iomuxc: pin-69 (1001d000.i2c) status -22
imx27-pinctrl 10015000.iomuxc: could not request pin 69 (MX27_PAD_I2C2_SDA) from group i2c2grp  on device 10015000.iomuxc
imx-i2c 1001d000.i2c: Error applying setting, reverse things back
imx-i2c: probe of 1001d000.i2c failed with error -22

Fix it by adding the correct I2C1 IOMUX entries for the pinctrl_i2c1 group.
