Merge drm/drm-next into drm-intel-gt-nextWe need4ba4f1afb6a9 ("perf: Generic hotplug support for a PMU with a scope")in order to land a i915 PMU simplification and a fix. That landed in 6.12and we are stuck at 6.9 so lets bump things forward.Signed-off-by: Tvrtko Ursulin List of files: /linux/Documentation/ABI/testing/sysfs-driver-spi-intel

Otherwise the big changes are the new drivers that have been added: - Completion of the conversion to spi_alloc_host()/_target() and removal of the old naming. - Cleanups for Rockchip drivers, these brought in a new logging helper in the driver core for warnings during probe. - Support for configuration of the word delay via spidev_test. - Support for AMD HID2 controllers, Apple SPI controller and Realtek SPI-NAND controllers"* tag 'spi-v6.13' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi: (58 commits) spi: imx: support word delay spi: imx: pass struct spi_transfer to prepare_transfer() spi: cs42l43: Add GPIO speaker id support to the bridge configuration spi: Delete useless checks spi: apple: Remove unnecessary .owner for apple_spi_driver spi: spidev_test: add support for word delay spi: apple: Add driver for Apple SPI controller spi: dt-bindings: apple,spi: Add binding for Apple SPI controllers spi: Use of_property_present() for non-boolean properties spi: zynqmp-gqspi: Undo runtime PM changes at driver exit time spi: spi-mem: rtl-snand: Correctly handle DMA transfers spi: tegra210-quad: Avoid shift-out-of-bounds spi: axi-spi-engine: Emit trace events for spi transfers dt-bindings: spi: sprd,sc9860-spi: convert to YAML spi: Replace deprecated PCI functions spi: dt-bindings: samsung: Add a compatible for samsung,exynos8895-spi spi: spi-mem: Add Realtek SPI-NAND controller dt-bindings: spi: Add realtek,rtl9301-snand spi: make class structs const spi: dt-bindings: brcm,bcm2835-aux-spi: Convert to dtschema ...

b1258105f9ce5203f48a47fd2f2cec8c38c41841 - spi: intel: Add protected and locked attributes

Wed, 09 Oct 2024 08:22:44 +0200

spi: intel: Add protected and locked attributesThe manufacturing access to the PCH/SoC SPI device is traditionallyperformed via userspace driver accessing registers via /dev/mem but dueto security concerns /dev/mem access is being much restricted, hence thereason for utilizing dedicated Intel PCH/SoC SPI controller driver,which is already implemented in the Linux kernel.Intel PCH/SoC SPI controller protects the flash storage via twomechanisms one is the via region protection registers and second viaBIOS lock. The BIOS locks only the BIOS regions usually 0 and/or 6.The device always boots with BIOS lock set, but during manufacturing theBIOS lock has to be lifted in order to enable the write access. This canbe done by passing "writeable=1" in the command line when the driver isloaded. This "locked" state is exposed through new sysfs attributes(intel_spi_locked, intel_spi_bios_locked).Second, also the region protection status is exposed via sysfs attribute(intel_spi_protected) as the manufacturing will need the both files inorder to validate that the device is properly sealed.Includes code written by Tamar Mashiah.Signed-off-by: Alexander Usyskin Co-developed-by: Tomas Winkler Signed-off-by: Tomas Winkler Reviewed-by: Andy Shevchenko Signed-off-by: Mika Westerberg Link: https://patch.msgid.link/20241009062244.2436793-1-mika.westerberg@linux.intel.comSigned-off-by: Mark Brown List of files: /linux/Documentation/ABI/testing/sysfs-driver-spi-intel
