[PATCH 00/13] spi: add driver for Intel discrete graphics

[Alexander Usyskin]

Add driver for access to Intel discrete graphics card
internal SPI device.
Expose device on auxiliary bus by i915 and Xe drivers and
provide spi driver to register this device with MTD framework.

This is a rewrite of "drm/i915/spi: spi access for discrete graphics"
series with connection to the Xe driver and splitting
the spi driver part to separate module in spi subsystem.

Alexander Usyskin (13):
  spi: add auxiliary device for intel dg spi
  drm/i915/spi: add spi device for discrete graphics
  drm/i915/spi: add intel_spi_region map
  drm/i915/spi: add support for access mode
  spi: add driver for intel graphics on-die spi device
  spi: intel-dg: implement region enumeration
  spi: intel-dg: implement spi access functions
  spi: intel-dg: spi register with mtd
  spi: intel-dg: implement mtd access handlers
  spi: intel-dg: align 64bit read and write
  spi: intel-dg: wake card on operations
  drm/xe/spi: add on-die spi device
  drm/xe/spi: add support for access mode
