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. V5: depend solely on AUXILIARY_BUS, not on COMPILE_TEST disable spi driver on virtual function in Xe, no spi device there 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 MAINTAINERS | 7 + drivers/gpu/drm/i915/Makefile | 4 + drivers/gpu/drm/i915/i915_driver.c | 6 + drivers/gpu/drm/i915/i915_drv.h | 4 + drivers/gpu/drm/i915/i915_reg.h | 1 + drivers/gpu/drm/i915/spi/intel_spi.c | 101 +++ drivers/gpu/drm/i915/spi/intel_spi.h | 15 + drivers/gpu/drm/xe/Makefile | 1 + drivers/gpu/drm/xe/regs/xe_gsc_regs.h | 4 + drivers/gpu/drm/xe/xe_device.c | 3 + drivers/gpu/drm/xe/xe_device_types.h | 8 + drivers/gpu/drm/xe/xe_heci_gsc.c | 5 +- drivers/gpu/drm/xe/xe_pci.c | 5 + drivers/gpu/drm/xe/xe_spi.c | 113 ++++ drivers/gpu/drm/xe/xe_spi.h | 15 + drivers/spi/Kconfig | 11 + drivers/spi/Makefile | 1 + drivers/spi/spi-intel-dg.c | 863 ++++++++++++++++++++++++++ include/linux/intel_dg_spi_aux.h | 27 + 19 files changed, 1190 insertions(+), 4 deletions(-) create mode 100644 drivers/gpu/drm/i915/spi/intel_spi.c create mode 100644 drivers/gpu/drm/i915/spi/intel_spi.h create mode 100644 drivers/gpu/drm/xe/xe_spi.c create mode 100644 drivers/gpu/drm/xe/xe_spi.h create mode 100644 drivers/spi/spi-intel-dg.c create mode 100644 include/linux/intel_dg_spi_aux.h
