serial: pl011: Remove legacy serial driver options

2026-04-02T17:13:16+00:00

There are no longer any users of the legacy non-DM pl01x serial driver.
This lets us remove both CONFIG_PL011_SERIAL as well as
CONFIG_PL011_SERIAL_RLCR references. We still have SPL users of the
non-DM portions of the code.

Drop all duplicate newlines. No functional change.

kbuild: Remove uncmd_spl logic

2022-12-23T15:15:13+00:00

At this point in the conversion there should be no need to have logic to
disable some symbol during the SPL build as all symbols should have an
SPL counterpart.

The main real changes done here are that we now must make proper use of
CONFIG_IS_ENABLED(DM_SERIAL) rather than many of the odd tricks we
developed prior to CONFIG_IS_ENABLED() being available.

dm: treewide: Rename ofdata_to_platdata() to of_to_plat()

2020-12-13T23:51:09+00:00

This name is far too long. Rename it to remove the 'data' bits. This makes
it consistent with the platdata->plat rename.

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.

bcm283x_pl011: Flush RX queue after setting baud rate

2018-03-09T17:31:04+00:00

After the UART was initialized, we may still have bogus data in the
RX queue if it was enabled with incorrect pin muxing before.

So let's flush the RX queue whenever we initialize baud rates.

This fixes a regression with the dynamic pinmuxing code when enable_uart=1
is not set in config.txt on Raspberry Pis that use pl011 for serial.

bcm2835_pl011_serial: Add BCM2835 specific serial driver

2018-01-28T17:27:36+00:00

On bcm2835 we need to ensure we only access serial devices that are
muxed to the serial output pins of the pin header. To achieve this
for the pl011 device, add a bcm2835 specific pl011 wrapper device
that does this check but otherwise behaves like a pl011 device.

dm: serial: Tidy up the pl01x driver

2014-10-22T16:36:57+00:00

Adjust the driver so that leaf functions take a pointer to the serial port
register base. Put all the global configuration in the init function, and
use the same settings from then on.

This makes it much easier to move to driver model without duplicating the
code, since with driver model we use platform data rather than global
settings.

The driver is compiled with either the CONFIG_PL010_SERIAL or
CONFIG_PL011_SERIAL option and this determines the uart type. With driver
model this needs to come in from platform data, so create a new
CONFIG_PL01X_SERIAL config which brings in the driver, and adjust the
driver to support both peripheral variants.
