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.

With this we have: dev_add_param_<type><access> "type" is one of: int32, uint32, int64, uint64, string, mac, ipv4, enum, bitmask The improvement here is that we now can exactly specify the width of the int type parameters and also correctly distinguish between signed and unsigned variables which means that a variable no longer ends up with INT_MAX when it's assigned -1. "access" can be empty for regular read/write parameter, "_ro" for readonly parameters which get their value from a variable pointer in the background or "_fixed" for parameters which are set to a fixed value (without a pointer in the background). Some more exotic types are not (yet) implemented, like dev_add_param_ip_ro. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Sascha Hauer committed on 11 Apr 2017
