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. V2: Replace dev_* prints with drm_* prints in drm (xe and i915) patches. Enable NVM device on Battlemage HW (xe driver patch) Fix overwrite register address (xe driver patch) Add Rodrigo's r-b 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 MAINTAINERS | 7 + drivers/gpu/drm/i915/Makefile | 4 + drivers/gpu/drm/i915/i915_driver.c | 6 + drivers/gpu/drm/i915/i915_drv.h | 3 + drivers/gpu/drm/i915/i915_reg.h | 1 + drivers/gpu/drm/i915/intel_nvm.c | 117 ++++ drivers/gpu/drm/i915/intel_nvm.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_nvm.c | 130 ++++ drivers/gpu/drm/xe/xe_nvm.h | 15 + drivers/gpu/drm/xe/xe_pci.c | 6 + drivers/mtd/devices/Kconfig | 11 + drivers/mtd/devices/Makefile | 1 + drivers/mtd/devices/mtd-intel-dg.c | 841 ++++++++++++++++++++++++++ include/linux/intel_dg_nvm_aux.h | 27 + 19 files changed, 1201 insertions(+), 4 deletions(-) create mode 100644 drivers/gpu/drm/i915/intel_nvm.c create mode 100644 drivers/gpu/drm/i915/intel_nvm.h create mode 100644 drivers/gpu/drm/xe/xe_nvm.c create mode 100644 drivers/gpu/drm/xe/xe_nvm.h create mode 100644 drivers/mtd/devices/mtd-intel-dg.c create mode 100644 include/linux/intel_dg_nvm_aux.h -- 2.43.0
