From 1f1e46b83b7db08c8db31816c857e27da84d4ca3 Mon Sep 17 00:00:00 2001 From: Benedikt Niedermayr Date: Wed, 2 Nov 2022 14:30:47 +0100 Subject: [PATCH] dt-bindings: memory-controllers: ti,gpmc: add wait-pin polarity The GPMC controller has the ability to configure the polarity for the wait pin. The current properties do not allow this configuration. This binding directly configures the WAITPINPOLARITY bit in the GPMC_CONFIG register by setting the "ti,wait-pin-polarity" dt-property.
