AMD/Xilinx Versal device serial IP has its own power domain, so add an optional property to describe it.

2021-05-27dt-bindings: serial: pl011: Delete an incorrect compatible stringZhen Lei1-6/+3
The compatible strings "zte,zx296702-uart" and "arm,primecell" are a combination, but commit 89d4f98ae90d ("ARM: remove zte zx platform") removes only the former. It is incorrect to match driver pl011 based only on the remaining "arm,primecell". Delete it.

I made a list and asked around which ones are no longer in use, and received confirmation about six ARM platforms and the TI C6x architecture that have all reached the end of their life upstream, with no known users remaining: - efm32 - added in 2011, first Cortex-M, no notable changes after 2013 - picoxcell - added in 2011, abandoned after 2012 acquisition - prima2 - added in 20111, no notable changes since 2015 - tango - added in 2015, sporadic changes until 2017, but abandoned - u300 - added in 2009, no notable changes since 2013 - zx - added in 2015 for both 32, 2017 for 64 bit, no notable changes - arch/c6x - added in 2011, but work stalled soon after that A number of other platforms on the original list turned out to still have users. In some cases there are out-of-tree patches and users that plan to contribute them in the future, in other cases the code is complete and works reliably" Link: https://lore.kernel.org/lkml/CAK8P3a2DZ8xQp7R=H=wewHnT2=a_=M53QsZOueMVEf7tOZLKNg@mail.gmail.com/ * tag 'arm-platform-removal-v5.12' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: ARM: remove u300 platform ARM: remove tango platform ARM: remove zte zx platform ARM: remove sirf prima2/atlas platforms c6x: remove architecture MAINTAINERS: Remove deleted platform efm32 ARM: drop efm32 platform ARM: Remove PicoXcell platform support ARM: dts: Remove PicoXcell platforms
2021-01-29dt-bindings: Cleanup standard unit propertiesRob Herring1-2/+0
Properties with standard unit suffixes already have a type and don't need type definitions. They also default to a single entry, so 'maxItems: 1' can be dropped. adi,ad5758 is an oddball which defined an enum of arrays. While a valid schema, it is simpler as a whole to only define scalar constraints.

2021-01-20ARM: remove zte zx platformArnd Bergmann1-2/+0
The ZTE ZX set-top-box SoC platform was added in 2015 by Jun Nie, with Baoyou Xie and Shawn Guo subsequently becoming maintainers after the addition of the 64-bit variant. However, the only machines that were ever supported upstream are the reference designs, not actual set-top-box devices that would benefit from this support. All ZTE set-top-boxes from the past few years seem to be based on third-party SoCs. While there is very little information about zx296702 and zx296718 on the web, I found some references to other chips from the same family, such as zx296716 and zx296719, which were never submitted for upstream support. Finally, there is no support for the GPU on either of them, with the lima and panfrost device drivers having been added after work on the zx platform had stopped. Shawn confirmed that he has not seen any interest in this platform for the past four years, and that it can be removed. Thanks to Jun and Shawn for maintaining this platform over the past five years.

2020-05-03dt-bindings: Remove cases of 'allOf' containing a '$ref'Rob Herring1-6/+4
json-schema versions draft7 and earlier have a weird behavior in that any keywords combined with a '$ref' are ignored (silently). The correct form was to put a '$ref' under an 'allOf'. This behavior is now changed in the 2019-09 json-schema spec and '$ref' can be mixed with other keywords. The json-schema library doesn't yet support this, but the tooling now does a fixup for this and either way works. This has been a constant source of review comments, so let's change this treewide so everyone copies the simpler syntax. Scripted with ruamel.yaml with some manual fixups. Some minor whitespace changes from the script.

2019-01-18dt-bindings: serial: Convert arm,pl011 to json-schemaRob Herring1-0/+126
Convert the arm,pl011 binding to DT schema using json-schema. The zte,zx296702-uart binding appears to be broken as the dts files are missing 'arm,primecell'. That's included in the schema here to throw a warning.
