[PATCH v7 00/12] Add support for sam9x7 SoC family

[PATCH v7 00/12] Add support for sam9x7 SoC family

[Varshini Rajendran]

This patch series adds support for the new SoC family - sam9x7.
 - The device tree, configs and drivers are added
 - Clock driver for sam9x7 is added
 - Support for basic peripherals is added
 - Target board SAM9X75 Curiosity is added

 Changes in v7:
 --------------

 - Addressed all the review comments in the patches
 - Dropped patches that are applied from the series
 - Removed sfr node from the DT to add it later after creating the right
   DT documentation for microchip sfr IPs.
 - All the specific changes are captured in the corresponding patches

 Changes in v6:
 --------------

 - Addressed all the review comments in the patches
 - Picked up all Acked-by and Reviewed-by tags
 - Reverted the IRQ patch to that of version 3 of the same series
 - All the specific changes are captured in the corresponding patches

 Changes in v5:
 --------------

 - Addressed all the review comments in the patches
 - Picked up all Acked-by and Reviewed-by tags
 - Dropped applied patches from the series
 - Addressed the ABI breakage reported in the IRQ patch
 - All the specific changes are captured in the corresponding patches

 Changes in v4:
 --------------

 - Addressed all the review comments in the patches
 - Picked up all Acked-by and Reviewed-by tags
 - Dropped applied patches from the series
 - Added pwm node and related dt binding documentation
 - Added support for exporting some clocks to DT
 - Dropped USB related patches and changes. See NOTE.
 - All the specific changes are captured in the corresponding patches

 NOTE: Owing to the discussion here
 https://lore.kernel.org/linux-devicetree/CAL_JsqJ9PrX6fj-EbffeJce09MXs=B7t+KS_kOinxaRx38=WxA@mail.gmail.com/
 the USB related changes are dropped from this series in order to enable
 us to work on the mentioned issues before adding new compatibles as
 said. The issues/warnings will be addressed in subsequent patches.
 After which the USB related support for sam9x7 SoCs will be added. Hope
 this works out fine.

 Changes in v3:
 --------------

 - Fixed the DT documentation errors pointed out in v2.
 - Dropped Acked-by tag in tcb DT doc patch as it had to be adapted
   according to sam9x7 correctly.
 - Picked by the previously missed tags.
 - Dropped this patch "dt-bindings: usb: generic-ehci: Document clock-names
   property" as the warning was not found while validating DT-schema for
   at91-sam9x75_curiosity.dtb.
 - Dropped redundant words in the commit message.
 - Fixed the CHECK_DTBS warnings validated against
   at91-sam9x75_curiosity.dtb.
 - Renamed dt nodes according to naming convention.
 - Dropped unwanted status property in dts.
 - Removed nodes that are not in use from the board dts.
 - Removed spi DT doc patch from the series as it was already applied
   and a fix patch was applied subsequently. Added a patch to remove the
   compatible to adapt sam9x7.
 - Added sam9x7 compatibles in usb dt documentation.


 Changes in v2:
 --------------

 - Added sam9x7 specific compatibles in DT with fallbacks
 - Documented all the newly added DT compatible strings
 - Added device tree for the target board sam9x75 curiosity and
   documented the same in the DT bindings documentation
 - Removed the dt nodes that are not supported at the moment
 - Removed the configs added by previous version that are not supported
   at the moment
 - Fixed all the corrections in the commit message
 - Changed all the instances of copyright year to 2023
 - Added sam9x7 flag in PIT64B configuration
 - Moved macro definitions to header file
 - Added another divider in mck characteristics in the pmc driver
 - Fixed the memory leak in the pmc driver
 - Dropped patches that are no longer needed
 - Picked up Acked-by and Reviewed-by tags

Applied to at91-soc, thanks!

[PATCH v7 03/12] dt-bindings: interrupt-controller: Add support for sam9x7 aic

[Varshini Rajendran]

Document the support added for the Advanced interrupt controller(AIC)
chip in the sam9x7 SoC family. New compatible is introduced to capture
the differences like the number of interrupts supported in the
integration of the IP to that of the previous designs.

The driver and dts changes in this patch series looks good to me.

This is an RGB LED like on other Microchip Curiosity boards, right?
So three colors in a single package?  What about using the
"leds-group-multicolor" driver instead of adding these as separate
LEDs?

See Documentation/devicetree/bindings/leds/leds-group-multicolor.yaml
for reference.  I tried that lately on the SAM9X60 Curiosity out of
curiosity, and it's a nice interface from userspace POV.

Besides: According to
Documentation/devicetree/bindings/leds/common.yaml the group name
should be 'led-controller' instead of 'leds'.

Yes this is an RGB LED like the others. But we have different pinctrls 
and some of them are multiplexed. In this case, the pin pioC 21 is used 
both as green LED and a PWM for an LVDS display (device node support to 
be added once the base DTS is merged, driver support already in place 
[1]). This is the reason these LEDs have different pinctrls and cannot 
be added as a single multicolor node. Hope this answers your question 
here and in the other mail.

I can maybe send another version for this change.

Related to above.  These three can be configured together in one
group.  See other microchip board dts files for reference.

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade

Re: [PATCH v7 00/12] Add support for sam9x7 SoC family

[Varshini.Rajendran]

Hi all,

I would like to express my sincere gratitude for the time and effort you 
offered to review this series. This has led to almost 38 patches getting 
merged and integrated in linux-next. Thanks !

Could the rest of the series be merged ? since this 7th version has not 
received any review comments that needs to be resolved. Thanks again.
