Lots of tiny driver core changes and cleanups happened this cycle, but the two major things are: - firmware_loader reorganization and additions including the ability to have XZ compressed firmware images and the ability for userspace to initiate the firmware load when it needs to, instead of being always initiated by the kernel. FPGA devices specifically want this ability to have their firmware changed over the lifetime of the system boot, and this allows them to work without having to come up with yet-another-custom-uapi interface for loading firmware for them. - physical location support added to sysfs so that devices that know this information, can tell userspace where they are located in a common way. Some ACPI devices already support this today, and more bus types should support this in the future. Smaller changes include: - driver_override api cleanups and fixes - error path cleanups and fixes - get_abi script fixes - deferred probe timeout changes. It's that last change that I'm the most worried about. It has been reported to cause boot problems for a number of systems, and I have a tested patch series that resolves this issue. But I didn't get it merged into my tree before 5.18-final came out, so it has not gotten any linux-next testing. I'll send the fixup patches (there are 2) as a follow-on series to this pull request. All have been tested in linux-next for weeks, with no reported issues other than the above-mentioned boot time-outs" * tag 'driver-core-5.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (55 commits) driver core: fix deadlock in __device_attach kernfs: Separate kernfs_pr_cont_buf and rename_lock. topology: Remove unused cpu_cluster_mask() driver core: Extend deferred probe timeout on driver registration MAINTAINERS: add Russ Weight as a firmware loader maintainer driver: base: fix UAF when driver_attach failed test_firmware: fix end of loop test in upload_read_show() driver core: location: Add "back" as a possible output for panel driver core: location: Free struct acpi_pld_info *pld driver core: Add "*" wildcard support to driver_async_probe cmdline param driver core: location: Check for allocations failure arch_topology: Trace the update thermal pressure kernfs: Rename kernfs_put_open_node to kernfs_unlink_open_file. export: fix string handling of namespace in EXPORT_SYMBOL_NS rpmsg: use local 'dev' variable rpmsg: Fix calling device_lock() on non-initialized device firmware_loader: describe 'module' parameter of firmware_upload_register() firmware_loader: Move definitions from sysfs_upload.h to sysfs.h firmware_loader: Fix configs for sysfs split selftests: firmware: Add firmware upload selftests ... 2022-06-01T17:30:18Z Linus Torvalds torvalds@linux-foundation.org 2022-06-01T17:30:18Z urn:sha1:129bdb30fb054875f2068ccce376b865076d9934 Pull spi fixes from Mark Brown: "A couple of fixes that came in during the merge window: a driver fix for spurious timeouts in the fsi driver and an improvement to make the core display error messages for transfer_one_message() to help people debug things" * tag 'spi-fix-v5.19-rc0' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi: spi: core: Display return code when failing to transfer message spi: fsi: Fix spurious timeout 2022-05-26T17:43:09Z Linus Torvalds torvalds@linux-foundation.org 2022-05-26T17:43:09Z urn:sha1:ecf0aa5317b0ad6bb015128a5b763c954fd58708 Pull ARMv4T/v5 multiplatform support from Arnd Bergmann: "This series has been 12 years in the making, it mostly finishes the work that was started with the founding of Linaro to clean up platform support in the kernel. The largest change here is a cleanup of the omap1 platform, which is the final ARM machine type to get converted to the common-clk subsystem. All the omap1 specific drivers are now made independent of the mach/*.h headers to allow the platform to be part of a generic ARMv4/v5 multiplatform kernel. The last bit that enables this support is still missing here while we wait for some last dependencies to make it into the mainline kernel through other subsystems. The s3c24xx, ixp4xx, iop32x, ep93xx and dove platforms were all almost at the point of allowing multiplatform kernels, this work gets completed here along with a few additional cleanup. At the same time, the s3c24xx and s3c64xx are now deprecated and expected to get removed in the future. The PXA and OMAP1 bits are in a separate branch because of dependencies. Once both branches are merged, only the three Intel StrongARM platforms (RiscPC, Footbridge/NetWinder and StrongARM1100) need separate kernels, and there are no plans to include these" * tag 'arm-multiplatform-5.19-1' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (61 commits) ARM: ixp4xx: Consolidate Kconfig fixing issue ARM: versatile: Add missing of_node_put in dcscb_init ARM: config: Refresh IXP4xx config after multiplatform ARM: omap1: add back omap_set_dma_priority() stub ARM: omap: fix missing declaration warnings ARM: omap: fix address space warnings from sparse ARM: spear: remove include/mach/ subdirectory ARM: davinci: remove include/mach/ subdirectory ARM: omap2: remove include/mach/ subdirectory integrator: remove empty ap_init_early() ARM: s3c: fix include path MAINTAINERS: omap1: Add Janusz as an additional maintainer ARM: omap1: htc_herald: fix typos in comments ARM: OMAP1: fix typos in comments ARM: OMAP1: clock: Remove noop code ARM: OMAP1: clock: Remove unused code ARM: OMAP1: clock: Fix UART rate reporting algorithm ARM: OMAP1: clock: Fix early UART rate issues ARM: OMAP1: Prepare for conversion of OMAP1 clocks to CCF ARM: omap1: fix build with no SoC selected ... 2022-05-26T13:43:29Z Eddie James eajames@linux.ibm.com 2022-05-25T16:58:52Z urn:sha1:ebf2a3521738520e12849b221fea24928b3f61ff All the other calls to the controller driver display the error return code.

This driver takes a slightly different approach to cover all 6 controllers. It does not make use of the controller register disabling Address and Data byte lanes because is not available on the AST2400 SoC. We could introduce a specific handler for new features available on recent SoCs if needed. As there is not much difference on performance, the driver chooses the common denominator: "User mode" which has been heavily tested in [1]. "User mode" is also used as a fall back method when flash device mapping window is too small. Problems to address with spi-mem were the configuration of the mapping windows and the calibration of the read timings. The driver handles them in the direct mapping handler when some knowledge on the size of the flash device is know. It is not perfect but not incorrect either. The algorithm is one from [1] because it doesn't require the DMA registers which are not available on all controllers. Direct mapping for writes is not supported (yet). I have seen some corruption with writes and I preferred to use the safer and proven method of the initial driver [1]. We can improve that later. The driver supports Quad SPI RX transfers on the AST2600 SoC but it didn't have the expected results. Therefore it is not activated yet. There are some issues on the pinctrl to investigate first.
