From bd25f9a69fa5accde66cf914154bdd64604d8f64 Mon Sep 17 00:00:00 2001 From: John Robertson Date: Tue, 1 Sep 2020 18:02:20 +0000 Subject: [PATCH] mips: dts: Fix PIC32MZDA GPIO register definitions The GPIO bank name for banks J and K are not correct when using the 'gpio' command from the console. The driver derives the bank name from the device tree instance string by using the instance value and adding 'A': gpio0@xxaddrxx is Bank A, gpio1@yyaddryy is Bank B and so on. On the PIC32, there is no Bank I so instances 8 and 9 need to be incremented as a minimum change. An alternative (less opaque) implementation would be to use a bank-name property instead but this would require modifying the driver code too.
