Subject: [PATCH 00/10] mtd: add driver for Intel discrete graphics

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

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

This series intended to be pushed through drm-xe-next.

Alexander Usyskin (10):
  mtd: add driver for intel graphics non-volatile memory device
  mtd: intel-dg: implement region enumeration
  mtd: intel-dg: implement access functions
  mtd: intel-dg: register with mtd
  mtd: intel-dg: align 64bit read and write
  mtd: intel-dg: wake card on operations
  drm/i915/nvm: add nvm device for discrete graphics
  drm/i915/nvm: add support for access mode
  drm/xe/nvm: add on-die non-volatile memory device
  drm/xe/nvm: add support for access mode
