[RESEND PATCH v9 0/3] Add support for lan966x flexcom chip-select configuration

[RESEND PATCH v9 0/3] Add support for lan966x flexcom chip-select configuration

[Kavyasree Kotagiri]

This patch series converts atmel-flexcom bindings into json-schema format.
Adds support for lan966x flexcom chip-select configurations and its
DT bindings.

v8 -> v9:
 - generated patches on linux-next v6.0.0-rc4 to resend.
 - Changed reference provided for spi bindings to atmel,at91rm9200-spi.yaml

v7 -> v8:
 - Added back patternProperties for child nodes.
 - Changed compatible string to microchip,lan9668-flexcom.

v6 -> v7:
 - Change filename to atmel,sama5d2-flexcom.yaml
 - Add #address-cells, #size-cells to flexcom node - Fixed warnings.

v5 -> v6:
 - Removed spi node from example as suggested by Rob and
   also pattern properties(spi dt-bindings conversion to yaml patch is under review).
   https://patchwork.kernel.org/project/linux-arm-kernel/patch/20220629125804.137099-1-sergiu.moga@microchip.com/
   Once this is accepted, I will add back spi example through new patch.

v4 -> v5:
 - Fix indentations of DT example.
 - Fix dt-schema errors - removed minItems, maxItems for allOf:if:then
   "reg" property as it is not required.

v3 -> v4:
 - Fix dtschema errors.
 - Add a condition to flexcom chip-selects configuration as chip-select
   lines are optional.

v2 -> v3:
 - changed IRQ flag in dt-bindings example.
 - added reg property specific to lan66x which is missed in v2.
 - used goto label for clk_disable in error cases.

v1 -> v2:
 - minor fix in title of dt-bindings.
 - Modified new dt properties usage in atmel,flexcom.yaml.
 - Used GENMASK and macros for maximum allowed values.
 - Use u32 values for flexcom chipselects instead of strings.
 - disable clock in case of errors.

-
-The Atmel Flexcom is just a wrapper which embeds a SPI controller, an I2C
-controller and an USART. Only one function can be used at a time and is chosen

-
-Required properties:
-- compatible:		Should be "atmel,sama5d2-flexcom"
-- reg:			Should be the offset/length value for Flexcom dedicated
-			I/O registers (without USART, TWI or SPI registers).
-- clocks:		Should be the Flexcom peripheral clock from PMC.
-- #address-cells:	Should be <1>
-- #size-cells:		Should be <1>
-- ranges:		Should be one range for the full I/O register region
-			(including USART, TWI and SPI registers).
-- atmel,flexcom-mode:	Should be one of the following values:
-			- <1> for USART
-			- <2> for SPI
-			- <3> for I2C
-
-Required child:
-A single available child device of type matching the "atmel,flexcom-mode"
-property.
-
-The phandle provided by the clocks property of the child is the same as one for
-the Flexcom parent.
-
-For other properties, please refer to the documentations of the respective
-device:

Running 'make dtbs_check' with the schema in this patch gives the

Note that it is not yet a requirement to have 0 warnings for dtbs_check.
This will change in the future.

this means it cannot be currently tested. Are you sure that there are no
warnings in all DTBs with your patches?

when both patchsets land).

[RESEND PATCH v9 2/3] dt-bindings: mfd: atmel,sama5d2-flexcom: Add new compatible string for lan966x

[Kavyasree Kotagiri]

LAN966x SoC flexcoms has two optional I/O lines. Namely, CS0 and CS1
in flexcom SPI mode. CTS and RTS in flexcom USART mode. These pins
can be mapped to lan966x FLEXCOM_SHARED[0-20] pins and usage depends on
functions being configured.

Signed-off-by: Kavyasree Kotagiri <kavyasree.kotagiri@microchip.com>
---
v8 -> v9:
 - No changes.

v7 -> v8:
 - Changed compatible string to microchip,lan9668-flexcom.

v6 -> v7:
 - Add #address-cells, #size-cells to flx3 example.

v5 -> v6:
 - Removed spi node from flx3 example.

v4 -> v5:
 - Fixed indentations and dt-schema errors.
 - No errors seen with 'make dt_binding_check'.

v3 -> v4:
 - Added else condition to allOf:if:then.

v2 -> v3:
 - Add reg property of lan966x missed in v2.

v1 -> v2:
 - Use allOf:if:then for lan966x dt properties

[RESEND PATCH v9 2/3] dt-bindings: mfd: atmel,sama5d2-flexcom: Add new compatible string for lan966x

[Kavyasree Kotagiri]

LAN966x SoC flexcoms has two optional I/O lines. Namely, CS0 and CS1
in flexcom SPI mode. CTS and RTS in flexcom USART mode. These pins
can be mapped to lan966x FLEXCOM_SHARED[0-20] pins and usage depends on
functions being configured.

Signed-off-by: Kavyasree Kotagiri <kavyasree.kotagiri@microchip.com>
---
v8 -> v9:
 - No changes.

v7 -> v8:
 - Changed compatible string to microchip,lan9668-flexcom.

v6 -> v7:
 - Add #address-cells, #size-cells to flx3 example.

v5 -> v6:
 - Removed spi node from flx3 example.

v4 -> v5:
 - Fixed indentations and dt-schema errors.
 - No errors seen with 'make dt_binding_check'.

v3 -> v4:
 - Added else condition to allOf:if:then.

v2 -> v3:
 - Add reg property of lan966x missed in v2.

v1 -> v2:
 - Use allOf:if:then for lan966x dt properties

Please add Acked-by/Reviewed-by tags when posting new versions. However,
there's no need to repost patches *only* to add the tags. The upstream
maintainer will do that for acks received on the version they apply.

https://elixir.bootlin.com/linux/v5.17/source/Documentation/process/submitting-patches.rst#L540

If a tag was not added on purpose, please state why and what changed.


Best regards,
Krzysztof

Yes, You are right.
I missed adding reviewed-by tag for 2/3 and 3/3 patches(which doesn't have any issues
while applying on latest version)
I haven't added tag for patch-1/3 as there is small change
(i.e., Changed reference provided for spi bindings to atmel,at91rm9200-spi.yaml)
while applying changes on latest version.

   chip-select lines are optional.

v2 -> v3:
 - used goto label for clk_disable in error cases.

v1 -> v2:
 - use GENMASK for mask, macros for maximum allowed values.
 - use u32 values for flexcom chipselects instead of strings.
 - disable clock in case of errors.

Hi All,

Please ignore this v9 patch series. I just now found that it is conflicting with https://lore.kernel.org/linux-arm-kernel/20220913142205.162399-6-sergiu.moga@microchip.com/
So, I will re-send my v8 patch series which is already reviewed by Rob Herring and claudiu.beznea
