-Subject: [PATCH] Revert "i2c: pxa: move to generic GPIO recovery"
-
-This reverts commit 0b01392c18b9993a584f36ace1d61118772ad0ca.
-
-Conversion of PXA to generic I2C recovery, makes the I2C bus completely
-lock up if recovery pinctrl is present in the DT and I2C recovery is
-enabled.
-
-So, until the generic I2C recovery can also work with PXA lets revert
-to have working I2C and I2C recovery again.
