pwm-backlight: Enable/disable the PWM before/after LCD enable toggle.
commit 5fb5caee92ba35a4a3baa61d45a78eb057e2c031 upstream. Before this patch the enable signal was set before the PWM signal and vice-versa on power off. This sequence is wrong, at least, it is on the different panels datasheets that I checked, so I inverted the sequence to follow the specs. For reference the following panels have the mentioned sequence: - N133HSE-EA1 (Innolux) - N116BGE (Innolux) - N156BGE-L21 (Innolux) - B101EAN0 (Auo) - B101AW03 (Auo) - LTN101NT05 (Samsung) - CLAA101WA01A (Chunghwa) Signed-off-by: Enric Balletbo i Serra <firstname.lastname@example.org> Acked-by: Daniel Thompson <email@example.com> Acked-by: Jingoo Han <firstname.lastname@example.org> Acked-by: Thierry Reding <email@example.com> Signed-off-by: Lee Jones <firstname.lastname@example.org> Signed-off-by: Arnd Bergmann <email@example.com> Signed-off-by: Greg Kroah-Hartman <firstname.lastname@example.org>
