Restore patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet"

2024-05-20T19:35:03+00:00

As part of bringing the master branch back in to next, we need to allow
for all of these changes to exist here.

Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet""

2024-05-19T14:16:36+00:00

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.

pinctrl: sunxi: remove GPIO_EXTRA_HEADER

2023-10-22T22:40:57+00:00

U-Boot's generic GPIO_EXTRA_HEADER is a convenience symbol to allow code
to more easily include platform specific GPIO headers. This should not
be needed in a DM world anymore, since the generic GPIO framework
handles that nicely.
For Allwinner boards we still need to deal with non-DM GPIO in the SPL,
but this should become the exception, not the rule.

Make this more obvious by removing the definition of GPIO_EXTRA_HEADER,
and just force every legacy user of platform specific GPIO to include
the new sunxi_gpio.h header explicitly. Everyone doing so should feel
ashamed and should find a way to avoid it from now on.

dm: core: Create a new header file for 'compat' features

2020-02-06T02:33:46+00:00

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.

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12+00:00

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.

video: ssd2828: Allow using 'pclk' as the PLL clock source

2015-01-22T11:34:56+00:00

Instead of using the internal 'tx_clk' clock source, it is also
possible to use the pixel clock signal from the parallel LCD
interface ('pclk') as the reference clock for PLL.

The 'tx_clk' clock speed may be different on different boards/devices
(the allowed range is 8MHz - 30MHz). Which is not very convenient,
especially considering the need to know the exact 'tx_clk' clock
speed. This clock speed may be difficult to identify without having
device schematics and/or accurate documentation/sources every time.

Using 'pclk' is free from all these problems.

video: Add support for SSD2828 (parallel LCD to MIPI bridge)

2015-01-22T11:34:56+00:00

SSD2828 can take pixel data coming from a parallel LCD interface
and translate it on the fly into MIPI DSI interface for driving
a MIPI compatible TFT display. SSD2828 is configured over SPI
interface, which may or may not have MISO pin wired up on some
hardware. So a write-only SPI mode also has to be supported.

The SSD2828 support code is implemented as a utility function
and needs to be called from real display drivers, which are
responsible for driving parallel LCD hardware in front of the
video pipeline. The usage instructions are provided as comments
in the header file.
