[Varshini Rajendran <varshini.rajendran@microchip.com>]

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
