From ffeee420912eecf525564bb35b095b6bfa5d0de6 Mon Sep 17 00:00:00 2001 From: Julius Werner Date: Tue, 27 Mar 2018 16:22:00 -0700 Subject: rockchip: Add gpio_set() function The API is supposed to include a gpio_set() function that just toggles the state of a GPIO already configured as an output, even though we rarely need it since gpio_output() can already be used to initialze a GPIO to a default value while configuring it as an output. This function was forgotten on Rockchip, so this patch adds it now.
