2024-05-20Restore patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet"Tom Rini
As part of bringing the master branch back in to next, we need to allow for all of these changes to exist here. Reported-by: Jonas Karlman <jonas@kwiboo.se> Signed-off-by: Tom Rini <trini@konsulko.com>
2024-05-19Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet""Tom Rini
When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay Ethernet"' I failed to notice that b4 noticed it was based on next and so took that as the base commit and merged that part of next to master. This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

2022-04-28led: gpio: Use NOP uclass driver for top-level nodeMarek Vasut
The top level DT node of gpio-leds is not a LED itself, bind NOP uclass driver to it, and bind different LED uclass driver to its subnodes which represent the actual LEDs. This simplifies the probe() implementation and fixes the bogus top-level not-an-LED in 'led list' command output: ``` => led list led Error -121 <--- This is removed/fixed by this patch green:user0 off ``` Signed-off-by: Marek Vasut <marex@denx.de> Cc: Patrice Chotard <patrice.chotard@foss.st.com> Cc: Patrick Delaunay <patrick.delaunay@foss.st.com> Cc: Sean Anderson <seanga2@gmail.com> Cc: Simon Glass <sjg@chromium.org> Cc: Steven Lawrance <steven.lawrance@softathome.com> Reviewed-by: Patrice Chotard <patrice.chotard@foss.st.com> Tested-by: Patrice Chotard <patrice.chotard@foss.st.com>
2022-04-28led: gpio: Check device compatible string to determine the top level nodeMarek Vasut
Since 2d1deaf88ed ("led: gpio: Drop duplicate OF "label" property parsing"), all LED nodes have some sort of label. Use device_is_compatible(..."leds-gpio") to determine whether this is a top-level node, since it is only the top level node which is compatible with "leds-gpio", the GPIO LEDs subnodes are not.

2020-12-13dm: treewide: Rename 'platdata' variables to just 'plat'Simon Glass
We use 'priv' for private data but often use 'platdata' for platform data. We can't really use 'pdata' since that is ambiguous (it could mean private or platform data). Rename some of the latter variables to end with 'plat' for consistency. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-12-13dm: treewide: Rename auto_alloc_size members to be shorterSimon Glass
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>
2020-10-08led: gpio: Default to using node name if label is absentSean Anderson
This more closely mirrors Linux's behaviour, and will make it easier to transition to using function+color in the future. Signed-off-by: Sean Anderson <seanga2@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org>

2020-02-05dm: core: Create a new header file for 'compat' featuresSimon Glass
At present dm/device.h includes the linux-compatible features. This requires including linux/compat.h which in turn includes a lot of headers. One of these is malloc.h which we thus end up including in every file in U-Boot. Apart from the inefficiency of this, it is problematic for sandbox which needs to use the system malloc() in some files. Move the compatibility features into a separate header file.

2018-08-10dm: led: move default state support in led uclassPatrick Delaunay
This patch save common LED property "default-state" value in post bind of LED uclass. The configuration for this default state is only performed when led_default_state() is called; It can be called in your board_init() or it could added in init_sequence_r[] in future.

2018-08-10Revert "dm: led: auto probe() LEDs with "default-state""Patrick Delaunay
This reverts commit bc882f5d5c7b4d6ed5e927bf838863af43c786e7. because this patch adds the probe of LED driver during the binding phasis. It is not allowed in driver model because the drivers (clock, pincontrol) needed by the LED driver can be also probed before the binding of all the device and it is a source of problems.

2018-05-08dm: led: auto probe() LEDs with "default-state"Patrick Bruenn

2018-05-08dm: led: Support "default-state" propertyPatrick Bruenn
Add support for the device tree property "default-state". This feature might be useful for LEDs indicating "power on" or similar states. Note: Even with this commit gpio-leds remain in reset state. That's because the led_gpio is not probed until DM_FLAG_ACTIVATED is set. Signed-off-by: Patrick Bruenn <p.bruenn@beckhoff.com>
2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
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>
2018-04-27Remove unnecessary instances of DECLARE_GLOBAL_DATA_PTRTom Rini
