2023-10-22video: simple_panel: use regulator_set_enable_if_allowedSvyatoslav Ryhel1-5/+5
With the commit 4fcba5d556b4 ("regulator: implement basic reference counter") the return value of regulator_set_enable may be EALREADY or EBUSY for fixed/gpio regulators and may be further expanded on all regulators. Change to use the more relaxed regulator_set_enable_if_allowed to continue if regulator already was enabled or disabled. Signed-off-by: Svyatoslav Ryhel <clamor95@gmail.com>

2020-12-13dm: treewide: Rename ofdata_to_platdata() to of_to_plat()Simon Glass1-2/+2
This name is far too long. Rename it to remove the 'data' bits. This makes it consistent with the platdata->plat rename. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-12-13dm: treewide: Rename auto_alloc_size members to be shorterSimon Glass1-1/+1
This construct is quite long-winded. In earlier days it made some sense since auto-allocation was a strange concept. But with driver model now used pretty universally, we can shorten this to 'auto'. This reduces verbosity and makes it easier to read. Coincidentally it also ensures that every declaration is on one line, thus making dtoc's job easier. Signed-off-by: Simon Glass <sjg@chromium.org>

2018-10-09panel: Expand the backlight supportSimon Glass1-2/+18
At present the panel can be turned on but not off, and the brightness cannot be controlled at run-time. Add a new API function to both the panel and backlight uclasses to handle this. Enhance the PWM backlight driver to deal with custom levels properly and allow the backlight to be turned on and off. Update the test to cover thes new features.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini1-2/+1
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

2016-05-25exynos: video: Convert several boards to driver model for videoSimon Glass1-0/+2
Update several boards to use driver model for video. This involves changes to the EDP and FIMD (frame buffer) drivers. Existing PWM, simple-panel and pwm-backlight drivers are used. These work without additional configuration since they use the device tree settings in the same way as Linux. Boards converted are: - snow - spring - peach-pit - peach-pi All have been tested. Not converted: - MIPI display driver - s5pc210_universal - smdk5420 - smdk5250 - trats - trats2 Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Anatolij Gustschin <agust@denx.de> Signed-off-by: Minkyu Kang <mk7.kang@samsung.com>

At present simple-panel requires regulator support and will not build without it. But some panels do not have a power supply, or at least not one that can be controlled.

Adjust the driver to use driver model. The SOR becomes a bridge device. We use the normal simple_panel driver to handle the display itself.
