[PATCH v4 00/39] Add support for sam9x7 SoC family

[PATCH v4 00/39] 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 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

Remove microchip,sam9x60-spi compatible from the list as the driver used
has the compatible atmel,at91rm9200-spi and sam9x60 devices also use the
same compatible as fallback. So removing the microchip,sam9x60-spi
compatible from the list since it is not needed.

[PATCH v4 29/39] irqchip/atmel-aic5: Add support to get nirqs from DT for sam9x60 & sam9x7

[Varshini Rajendran]

Add support to get number of IRQs from the respective DT node for sam9x60
and sam9x7 devices. Since only this factor differs between the two SoCs,
this patch adds support for the same. Adapt the sam9x60 dtsi
accordingly.

Changes in v4:
- Changed the implementation to fetch the NIRQs from DT as per the
  comment to avoid introducing a new compatible when this is the only
  difference between the SoCs related to this IP.

Thanks!

[13/39] ASoC: dt-bindings: atmel-classd: add sam9x7 compatible
        commit: 89f3180d5915d4ea40e044ee102cd5c1ec81e7ef
[17/39] ASoC: dt-bindings: microchip: add sam9x7
        commit: c06a7a8e885753a024163bbb0dfd7349e8054643

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark

This doesn't make sense - this enum should be a const.
I don't really understand the idea behind of the original binding here that
allowed:
"microchip,sam9x60-dbgu", "microchip,sam9x60-usart", "atmel,at91sam9260-dbgu", "atmel,at91sam9260-usart"

Specifically, I don't get the purpose of the "microchip,sam9x60-usart".
Either make it
      - items:
          - enum:
              - microchip,sam9x60-dbgu
              - microchip,sam9x7-dbgu
          - const: microchip,sam9x60-usart
          - const: atmel,at91sam9260-dbgu
          - const: atmel,at91sam9260-usart
or add
      - items:
          - const: microchip,sam9x60-dbgu
          - const: atmel,at91sam9260-dbgu
          - const: atmel,at91sam9260-usart
or explain exactly why this needs to be
"chipa-dgbu", "chipa-usart", "chipb-dbgu", "chipb-dbgu"

Thanks,
Conor.

I find this wrong. I though we shall add compatibles for each SoC. Are
the registers and fields the same for the SPI IPs in these 2 SoCs? Even
if they are the same, are you sure the IPs are integrated in the same way?

The compatible has to be "chipa-usart", "chipb-usart", "chipa-dbgu", 
"chipb-dbgu" for the device to work as a debug console over UART
wher the chipa-<periph> is the device specific compatible
and the chipb-<periph> is the fallback compatible that the driver 
actually uses.

Maybe putting the 2 compatibles as 2 enums is not right. I will rephrase 
it as below.

       - items:
           - const: microchip,sam9x60-dbgu
           - const: microchip,sam9x60-usart
           - const: atmel,at91sam9260-dbgu
           - const: atmel,at91sam9260-usart
       - items:
           - const: microchip,sam9x7-dbgu
           - const: microchip,sam9x7-usart
           - const: atmel,at91sam9260-dbgu
           - const: atmel,at91sam9260-usart

Which two SoCs are you referring to ?
I am not removing the device specific compatible. I am only removing the 
additional fallback compatible.

As in,

compatible = "microchip,sam9x7-spi", "atmel,at91rm9200-spi";

instead of,

compatible = "microchip,sam9x7-spi", "microchip,sam9x60-spi", 
"atmel,at91rm9200-spi";

for the sam9x7 devices.

Hope this is clear. If I have it wrong please let me know.

it's clear now, thanks.

I see in the driver that microchip,sam9x60-spi compatible is not yet
used, thus removing the fallback to "microchip,sam9x60-spi" brings no
functional change. Would have made a difference if sam9x60-spi
implemented additional support that sam9x7-spi could have used as a
fallback. If you think that sam9x7-spi will not fallback to sam9x60-spi
in the future then:

This examples why you have "microchip,sam9x60-dbgu", "atmel,at91sam9260-dbgu"
and "atmel,at91sam9260-usart".
It does not explain "microchip,sam9x60-usart" though, I don't see what
purpose that serves. If used as a debug uart, you fall back to the
sam9260 debug uart compatible and if not you fall back to the sam9260
usart compatible.

In addition, the current setup implies that sam9x60 usart supports all
the features that the sam9260 debug usart does. I doubt that that is
true.

Thanks,
Conor.

[16/39] spi: dt-bindings: atmel,at91rm9200-spi: remove 9x60 compatible from list
        commit: 666db8fd4265f938795004838d2a9335ce7b9da1

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Here, if it is not used as debug uart it has to fallback to the default 
usart compatible which in this case should have a device specific 
compatible too right?

The common usart compatible looks as follows,

     compatible = "microchip,sam9x60-usart", "atmel,at91sam9260-usart";

meaning the 1st one is the device specific usart compatible and the 2nd 
one is the fallback compatible which the driver actually supports.

The debug uart looks as follows,

compatible = "microchip,sam9x60-dbgu", "atmel,at91sam9260-dbgu", 
"microchip,sam9x60-usart", "atmel,at91sam9260-usart";

In this case, there is a device specific debug uart compatible, a 
fallback tot he debug uart compatible and as you said if not used as a 
debug uart it should fallback and work as a normal uart device which has 
both a device specific compatible and a fallback to work.

In case the device specific compatible is supported with some other 
features in the driver in the future, the debug uart also should get its 
perk. Does this make sense?

This version here makes a lot more sense than what is currently in use
and what is being added in your original patch. I wouldn't object to
this being used.

Keep it alphanumerically sorted, thus after sam9x60 entry.

I don't know if you got any review comments w/ regards to this in the
previous email but having flexcoms and inner node grouped together is
easier to follow (at least to me). e.g.:

I can't find the schematics for this but these values here should reflect
the voltage that the board support not the ones that the PMIC itself
supports. Valid for all the other regulators.

Try to be compliant with coding style from here (valid everywhere):
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/devicetree/bindings/dts-coding-style.rst#n167

usually pinctrl label is something like the following in Microchip AT91 DTSes:
pinctrl_<ip-name>_default and node name is <ip-name>-default.

Please use the same rule everywhere.

This breaks the ABI. You should ensure old device trees are still working
with this patch.

As of [1] the order should be something like:
1/ compatible
2/ reg
3/ ranges
4/ #address-cells
   #size-cells

Please check the rest of the file to comply with this [1]

This one                               ^

and this one                            ^ should be alligned as of coding
style (see [1] above). Same for the rest of occurencies I will not comment on.

Usually the node name for this is poweroff. Any reason you changed it like
this?

Node name should be generic, e.g. clock-controller

microchip,sam9x7-gbpr seems undocummented.

This is documented in patch 28 [1] of this series. But double checking

version

I think poweroff fits better. Documentation is also using poweroff for node
name. The rest of at91 device uses it. And poweroff is what this controller
does (it is named shutdown controller).

The only older device that uses this API is sam9x60 and the newly added 
sam9x7. This change has been tested to be working fine in both the 
devices. If you still want me to use the macros as a fallback in the 
failure case I can do it. But this change was proposed to avoid adding 
macros in the first place. I can remove the error check just like they 
do while getting other device tree properties. Or if this is just a 
concern of the old devices working with the new change, then sam9x60 
works. Please let me know how to proceed.

There is a conflict. My bad, I missed mentioning it since the other node 
support is not added yet. I will add it in the next version.

Driver and binding changes should be in different patches. Having them
in the same patch is usually a red flag for ABI breakage.

Does it still work for a sam9x60 that does not have "microchip,nr-irqs"?
I can't see how it would, because you remove the define and return an
error. That's a pretty clear ABI breakage to me and I don't think it is
justified.

I just noticed that this property is not documented in a binding. The
first thing you would will be asked when trying to add that is "why can
this not be determined based on the compatible", which means back to
having a define in the driver.
That said, having specific $soc_aic5_of_init() functions for each SoC
seems silly when usually only the number of interrupts changes. The
number of IRQs could be in the match data and you could use
aic5_of_init in your IRQCHIP_DECLARE directly.

As Conor explained, the code in this patch should work with device trees
from previous kernel releases (thus not having microchip,nr-irqs DT binding).

Other maintainers picked some patches from this thread and I didn't get
an answer to my question. To be able to close this thread on my side I
applied this patch now to my for-nexxt branch

	https://git.kernel.org/pub/scm/linux/kernel/git/ukleinek/linux.git for-nexxt

. This is expected to be rebased once v6.9-rc1 is available, but it
won't get lost this way.

Best regards
Uwe
