From 0b0cb52bd80eda76c4b9921f5cf9c1b709d44e83 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Fri, 18 Oct 2019 17:41:53 +0200 Subject: video: backlight: tosa: Use GPIO lookup table The driver should not require a machine specific header. Change it to pass the GPIO line through a lookup table, and move the timing generator definitions into the drivers itself.
