From 3a711e0dd4e68f6b202db3f9e2c0086a8780da25 Mon Sep 17 00:00:00 2001 From: "H. Nikolaus Schaller" Date: Sat, 10 Mar 2018 12:00:01 +0100 Subject: [PATCH] gpio: pca953x: add compatibility for pcal6524 and pcal9555a The Pyra-Handheld originally used the tca6424 but recently we have replaced it by the pin and package compatible pcal6524. So let's add this to the bindings and the driver. And while we are at it, the pcal9555a does not have a compatible entry either but is already supported by the device id table. Signed-off-by: H.
