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. 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 | 97 +++ drivers/gpu/drm/i915/spi/intel_spi.h | 15 + drivers/gpu/drm/xe/Makefile | 1 + drivers/gpu/drm/xe/regs/xe_gsc_regs.h | 5 + 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 | 104 ++++ 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, 1178 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
