[PATCH v4 00/12] spi: add driver for Intel discrete graphics

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.

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

V4: fix white-spaces
    add check for discrete graphics missed in i915 intel_spi_fini

V3: rebase over drm-xe-next to enable CI run

V2: fix review comments
    fix signatures order
    depend spi presence in Xe on special flag,
     as not all new discrete cards have such spi

Alexander Usyskin (6):
  spi: add driver for intel graphics on-die spi device
  spi: intel-dg: align 64bit read and write
  spi: intel-dg: wake card on operations
  drm/i915/spi: add support for access mode
  drm/xe/spi: add on-die spi device
  drm/xe/spi: add support for access mode

Tomas Winkler (6):
  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
  drm/i915/spi: add spi device for discrete graphics
  drm/i915/spi: add intel_spi_region map
