Merge tag 'spi-v5.17' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi

Pull spi updates from Mark Brown:
 "This has mostly been a quiet release for the SPI subsystem, almost all
  cleanups and fixes to existing drivers.

  A couple of changes that stand out:

   - Cleanups and support for version specific features in the
     DesignWare controller.

   - Removal of support for Netlogic devices from the XLP driver, the
     platform had previously been removed by MIPS so the support
     couldn't be used.

   - Conversion of several DT bindings to YAML format"

+
+description:
+  Many SPI controllers need to add properties to peripheral devices. They could
+  be common properties like spi-max-frequency, spi-cpha, etc. or they could be
+  controller specific like delay in clock or data lines, etc. These properties
+  need to be defined in the peripheral node because they are per-peripheral and
+  there can be multiple peripherals attached to a controller. All those
+  properties are listed here. The controller specific properties should go in
+  their own separate schema that should be referenced from here.
