DT core:
- Add of_machine_device_match() and of_machine_get_match_data()
helpers and convert users treewide
- Fix bounds checking of address properties in FDT code. Rework the
code to have a single implementation of the bounds checks.
- Rework of_irq_init() to ignore any implicit interrupt-parent (i.e.
in a parent node) on nodes without an interrupt. This matches the
spec description and fixes some RISC-V platforms.
- Avoid a spurious message on overlay removal

Merge series from Andreas Kemnade <andreas@kemnade.info>:
Add a driver for the FP9931/JD9930 regulator which provides the
comparatively high voltages needed for electronic paper displays.
Datasheet for the FP9931 is at
https://www.fitipower.com/dl/file/flXa6hIchVeu0W3K
Although it is in English, it seems to be only downloadable
from the Chinese part of that website.
For the JD9930 there can be a datasheet found at
https://e2e.ti.com/cfs-file/__key/communityserver-discussions-components-files/196/JD9930_2D00_0.7_2D00_JUN_2D00_2019.pdf
To simplify things, include the hwmon part directly which is only
one register read and there are not other functions besides
regulators in this chip.
|
|
Document the FP9931/JD9930. As the FP9931 is a clear subset of the JD9930,
define it as a fallback compatible. GPIO names are same as in the datasheet
except for the EN pad which is described as "enable".

Merge series from AngeloGioacchino Del Regno <angelogioacchino.delregno@collabora.com>:
This series adds support for three new MediaTek PMICs: MT6316, MT6363
and MT6373 and their variants - used in board designs featuring the
MediaTek MT8196 Chromebook SoC, or the MT6991 Dimensity 9400 Smartphone
SoC.
In particular, MT6316 is a regulator, but the MT6363 and MT6373 PMICs
are multi-function devices, as they have and expose multiple sub-devices;
moreover, some of those also contain an interrupt controller, managing
internal IPs interrupts: for those, a chained interrupt handler is
registered, which parent is the SPMI controller itself.
This series adds support for all of the MT6316 regulator variants and
for MT6363, MT6373 SPMI PMICs and their interrupt controller.

MT6373 PMICs.

Merge series from Oleksij Rempel <o.rempel@pengutronix.de>:
This series adds input supply definitions for the NXP PCA9450 PMIC.
Some systems detect power events such as undervoltage before the PMIC.
To allow correct propagation of such events, each regulator must define
its upstream input supply. The first patch updates the devicetree
binding to document new *-supply properties, and the second patch adds
matching .supply_name entries in the driver.
Changes in this series:
- Document INL1, INB13, INB26 and INB45 supply properties
- Link all LDO and BUCK regulators to their corresponding input groups
|
|
Add missing supply properties for PCA945x input pin groups:
- inl1-supply (for LDOs)
- inb13-supply (for BUCK1/3)
- inb26-supply (for BUCK2/6)
- inb45-supply (for BUCK4/5)
These properties describe external power sources for each input group.

Merge series from Kamal Wadhwa <kamal.wadhwa@oss.qualcomm.com>:
This series contains patches to update rpmh-regulator driver and

boards with Qualcomm's next gen compute SoC - Glymur.
Device tree changes aren't part of this series and will be posted
separately after the official announcement of the Glymur SoC.

CMD-DB
Currently, CMD-DB names for RPMH regulators follow this format:
`^(smps|ldo|bob|vs)[a-n][1-9][0-9]?$`
Here, the `[a-n]` value is read from the `pmic-id` DT property,
which is unique to each PMIC present on the board.
Note that in this older CMD-DB name format the SPMI bus on which
a particular PMIC regulator exists was not apparent from its
CMD-DB name.
New targets like Glymur, where we have multiple SPMI buses,
overcome this limitation by following a new CMD-DB name format:
`^(L|S|B)[1-9][0-9]?[A-N]_E[0-3]$`
Here `[A-N]_E[0-3]` part will now be read from the `pmic-id` DT
prop and it includes the SPMI bus id `[0-3]` as well.
However, the PMIC ID part `[A-N]` of the CMD-DB name is now
unique only to the SPMI bus that the PMIC regulator is present
on. which means `L1B_E0` and `L1B_E1` are both possible CMD-DB
names for two different regulator LDOs present on two different
SPMI buses (bus id 0 and 1) on the same board.
Note that since the new `pmic-id` DT property is a combo of
PMIC ID and SPMI bus ID, so its still unique to each PMIC
present on the board.
Update the `pmic-id` property pattern information to reflect this
change in the driver handling to support this new CMD-DB naming
format while maintaining backward compatiblilty with old CMD-DB
naming format which is still supported for older/existing
targets.

The active-semi,act8945a binding is documented in multiple places. The
charger child node is documented in regulator/active-semi,act8945a.yaml
and power/supply/active-semi,act8945a-charger.yaml. An old text binding
is in mfd/act8945a.txt.
Update the regulator/active-semi,act8945a.yaml with the additional
descriptions and constraints from
power/supply/active-semi,act8945a-charger.yaml, and then remove it and
mfd/act8945a.txt.

Convert devicetree bindings for the Broadcom BCM59056 PMU MFD from
TXT to YAML format. This patch does not change any functionality;
the bindings remain the same.
The bindings have been split into two parts: the MFD binding and
a separate binding for the regulator node, to simplify the addition
of other models later (which have different regulators).

Some of the regulators on the MT6357 PMIC currently reference the
fixed-regulator dt-binding, which enforces the presence of a
regulator-fixed compatible. However since all regulators on the MT6357
PMIC are handled by a single mt6357-regulator driver, probed through
MFD, the compatibles don't serve any purpose. In fact they cause
failures in the DT kselftest since they aren't probed by the fixed
regulator driver as would be expected. Furthermore this is the only
dt-binding in this family like this: mt6359-regulator and
mt6358-regulator don't require those compatibles.
Commit d77e89b7b03f ("arm64: dts: mediatek: mt6357: Drop regulator-fixed
compatibles") removed the compatibles from Devicetree, but missed
updating the binding, which still requires them, introducing dt-binding
errors. Remove the compatible requirement by referencing the plain
regulator dt-binding instead to fix the dt-binding errors.
