The first patch updates the device tree bindings for leds-qcom-lpg to
include support for PMI8950 PWM.
The second patch adds a pwm node to the device tree for the PMI8950. This
node is found on some msm8953 devices, such as the Xiaomi Mido, and its
inclusion in the device tree will enable infrared LED functionality on
these devices.
The final patch adds support for the PMI8950 PWM to the leds-qcom-lpg
driver.
The PMI8950 PMIC contains one PWM channel.

* [PATCH net-next 0/3] net: stmmac: Add support for RZN1 GMAC devices

Hello everyone,
This is version one of my series that adds support for a Gigabit Ethernet
controller featured in the Renesas r9a06g032 SoC, of the RZ/N1 family. This
GMAC device is based on a Synopsys IP and is compatible with the stmmac driver.
My former colleague Clément Léger originally sent a series for this driver,
but an issue in bringing up the PCS clock had blocked the upstreaming
process. This issue has since been resolved by the following series:
https://lore.kernel.org/all/20240326-rxc_bugfix-v6-0-24a74e5c761f@bootlin.com/
This series consists of a devicetree binding describing the RZN1 GMAC
controller IP, a node for the GMAC1 device in the r9a06g032 SoC device
tree, and the GMAC driver itself which is a glue layer in stmmac.
Best Regards,
Romain Gantois

The RZ/N1 series of MPUs feature up to two Gigabit Ethernet controllers.
These controllers are based on Synopsys IPs. They can be connected to
RZ/N1 RGMII/RMII converters.
Add a binding that describes these GMAC devices.

Should I set the reqsize as below in sha_cra_init()? Seeing this in other crypto drivers.

This way of mapping is not only useful for the RK3399 but would also
help for the addition of other future PCI endpoint controller drivers.
For example, on several FPGA PCI endpoint IPs the window mapping is
also done by passing N bits from the mapped address and M bits from
the window mapping address (where N+M=bus width, e.g., 32 or 64).
Using AND/OR masks/operations to combine the bits for the hardware
address from the mapped address and map base uses less resources than
using add/subtract to get the hardware address from an unaligned map
base and offset. So I guess that more than a few IPs, being hard or
soft IPs, use this kind of mapping (to reduce size, logic, improve max
operating frequency, improve efficiency etc.)
Two major examples come to mind :
1) The AMD/Xilinx PCIe endpoint IP. The mapping is documentented in
"AXI Bridge for PCI Express Gen3 Subsystem Product Guide (PG194)" [1]
section BAR and Address Translation (Figure AXI to PCIe Address
Translation).
2) The Intel/Altera PCIe endpoint IP. The mapping is documented in
"Multi Channel DMA Intel® FPGA IP for PCI Express* User Guide" [2]
section 3.6. Root Port Address Translation Table Enablement.
Both those IPs don't have mainline support yet as PCIe endpoint
controllers but also use a similar kind of mapping as suggested here
for the RK3399. So these changes would also make the addition of these
controller drivers easier.
The new mapping scheme also makes it much clearer in the PCI endpoint
framework. Because without it some mapping operation would fail
because of alignment requirements in the controller, this requires
extra code and checks in the drivers that implement the endpoint
functions. With the current state of the PCI endpoint controller
framework there is no good way to express that the controller does an
AND/OR mask combination to create the hardware address and therefore
requires the map to be aligned to the window size, rather than doing a
window base addition with an offset (subtraction) in the mapping. This
could benefit from further clarification in the endpoint framework.
Best regards,
Rick

Yes if you places the fallback request at the end of reqctx then
this is the correct reqsize.

- rebase patch "arm64: dts: st: add rcc support for STM32MP25"
with next-20240207 tag
v8:
- use .index of clk_parent_data struct to define a parent
- remove unnecessary dependency check with SCMI clock driver
- convert to platform device APIs
- convert to devm_of_clk_add_hw_provider()
- convert single value enum to a define

dt-bindings: stm32: add clocks and reset binding for stm32mp25
- remove unnecessary includes
- migrate clock parents to struct clk_parent_data and remove
CLK_STM32_XXX() macros to have a more readble code
- use platform device APIs (devm_of_iomap() instead of_iomap())
- move content of stm32mp25_rcc_init() to stm32mp25_rcc_clocks_probe()
- simply get_clock_deps()
- add const to stm32mp25_data struct

The majority of parents are SCMI clocks, then dt-bindings must be fixed.

In-Reply-To: <20240402125312.277052-1-gabriel.fernandez@foss.st.com>
From: Gabriel Fernandez <gabriel.fernandez@foss.st.com>
This driver is intended for the STM32MP25 clock family and utilizes
the stm32-core API, similar to the stm32mp13 clock driver.

The new symbol doesn't exist in the pinctrl tree, so the driver will
cease to be compilable. Yangyu sent a standalone version of these symbol
changes:
https://lore.kernel.org/all/tencent_DB11214C8D0D7C48829ADA128E7BB8F13108@qq.com/
That whole series needs to go through one tree though, for the same reason.
If your ack transfers to that (identical patch) I can take the whole lot
via the soc tree for v6.10.

The documentation here is called "a common sense".
The C language is built like this and we expect that nobody will
invest into the dependency hell that we have already, that's why IWYU

This sounds like a mess. devm_ is expected to be used only for the
->probe() stage, otherwise you may consider cleanup.h (__free() macro)
to have automatic free at the paths where memory is not needed.
And the function naming doesn't suggest that you have a probe-remove
pair. Moreover, if the init-deinit part is called in the probe-remove,
the devm_ must not be mixed with non-devm ones, as it breaks the order
and leads to subtle mistakes.

* [RFC PATCH 0/6] Support ROHM BD96801 scalable PMIC

Support ROHM BD96801 "scalable" PMIC.
The ROHM BD96801 is automotive grade PMIC, intended to be usable in
multiple solutions. The BD96801 can be used as a stand-alone, or together
with separate 'companion PMICs'. This modular approach aims to make this
PMIC suitable for various use-cases.
This RFC series is a product of a _long_ process. The product has been
re-designed a few times and this series has been sitting in my git
forgotten for long periods of time, then been re-worked when new design
has been available, after which it has again been forgotten. Last week I
finally received the word that this product should've been stabilized,
digged up my last set of patches (from Nov 2021 - cover letter
reminding me the driver development had been done during 3 years...)
I think this is valid information for reviewers as it's good to keep an
eye on obsoleted practices - even though I tried updating this series.
This is sent as an RFC because of the regulator features which can be
configured only when the PMIC is in STBY state. This is described more
detailed in the regulator patch.
Another "oddity" is that the PMIC has two physical IRQ lines. When I
last wrote this patch in 2021 I had some naming collison in debugfs for
the IRQ domains. Back then I used:
irq_domain_update_bus_token(intb_domain, DOMAIN_BUS_WIRED);
to work-around the issue. Now, when rebasing to v6.9-rc1 the naming
collision was gone and things seemed to work. However, it'd be great if
the IRQ code in MFD driver was reviewed by greater minds :)
Rest of the series ought to be business as usual.

+ The PMIC provides intb and errb IRQ lines. The errb IRQ line is used

+ connecting/handling the errb can be omitted. However, there are cases
+ where the SoC is not powered by the PMIC. In that case it may be
+ useful to connect the errb and handle errb events.

* [RFC PATCH 5/6] watchdog: ROHM BD96801 PMIC WDG driver
From: Matti Vaittinen @ 2024-04-02 13:11 UTC (permalink / raw)
To: Matti Vaittinen, Matti Vaittinen

[-- Attachment #1: Type: text/plain, Size: 12479 bytes --]
Introduce driver for WDG block on ROHM BD96801 scalable PMIC.
This driver only supports watchdog with I2C feeding and delayed
response detection. Whether the watchdog toggles PRSTB pin or
just causes an interrupt can be configured via device-tree.
The BD96801 PMIC HW supports also window watchdog (too early
feeding detection) and Q&A mode. These are not supported by
this driver.
