[PATCH v3 1/4] gpio: pca953x: set the PCA_PCAL flag also when matching by DT
From: H. Nikolaus Schaller
Date: Tue Apr 10 2018 - 12:07:25 EST
The of_device_table is missing the PCA_PCAL flag so the
pcal6524 would be operated in tca6424 compatibility mode which
does not handle the new interrupt mask registers.
