Subject: [PATCH v6 00/27] Add support for sam9x7 SoC family
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 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
