From 496069b87eea631274c2c35fb6f8c45ad838436b Mon Sep 17 00:00:00 2001 From: Biju Das Date: Tue, 7 Aug 2018 08:57:02 +0100 Subject: [PATCH] gpio: rcar: Add GPIO hole support GPIO hole is present in RZ/G1C SoC. Valid GPIO pins on bank3 are in the range GP3_0 to GP3_16 and GP3_27 to GP3_29. The GPIO pins between GP3_17 to GP3_26 are unused. Add support for handling unused GPIO's.
