We could get rid of the tables after "backlight: pwm_bl: Fix heuristic to determine number of brightness levels" (https://lore.kernel.org/patchwork/patch/1087809/) lands. Ideally we would also have something like this series https://lore.kernel.org/patchwork/project/lkml/list/?series=399607 , to provide userspace information about the brightness scale. Currently Chrome OS would interpret Enric's table as being linear and adjust the brightness slider incorrectly. _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
