All of the changes were kept to a minimum and limited to impedance matching between Barebox/Linux driver API.

2018-06-21	898ec20 Browse files » video: backlight: add slew time parameter ... Currently the backlight implementation stretches a brightness change over a period of 100ms. While this is a fine default for PWM backlights, a user might wish to change this slew time to meet other constraints or even completely disable it for some backlight devices. Add a parameter and provide the default value from the backlight device.

From `b1cb4bb` Mon Sep 17 00:00:00 2001 From: Sam Ravnborg <sam@ravnborg.org> Date: Sat, 6 Jan 2018 14:33:53 +0100 Subject: [PATCH] atmel_lcdfb: introduce driver data Introduce driver data like known from the kernel. This allows us to get rid of the hack where the intensity bit support was included in the lcd wiring mode. (No longer any support for IBGR, IRBG) It has the nice side-effect that all places where we test for hacks can now use flags and not a set of cpu's. So we keep all the configuration in one place. The configuration is included for non-DT users.

2017-09-06	e272a2b Browse files » atmel_lcdfb: add DT support ... Some boards use "have_intensity_bit". To support this the syntax for lcd_wiring_mode was extended to include this info. This is an extension compared to the documented bindings, and an extension the kernel does not support (yet). The binding documents that there can be more than one gpio to power on/off the display but current implmentation supports only one gpio. There are no users that requires more than one gpio so this is good enough. The clk name used for hclk differs from device trees and platform data. We could rename the clocl used in platform data but the name "hclk" is not unique. Configure clockname based on configuration method. Devicetree => hclk Platform data => hck1 Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Sam Ravnborg authored on 20 Jul 2017 Sascha Hauer committed on 6 Sep 2017

	de7963e Browse files » atmel_lcdfb: define power_control gpio in platform_data ... Simplify board specific code by specifying the power_control gpio direct in platform data. Move registration of the GPIO to the driver so we no longer need to duplicate this for each board. As an intended side-effect there is no longer any references to platform_data outside atmel_lcdc_register() so remove it from struct atmel_lcdfb_info The implementation assumes that GPIO=0 is the same as no power control. This prevents us from using any GPIO=0 for power control, but this is not considered a problem for current users. Future DT users will not have this limitation. This commit include a fix so we will actually power down if requested. Previously this was hardcoded to ON.
