2024-10-02spi: spi-ti-qspi: remove redundant assignment to variable retColin Ian King
Variable ret is being assigned a value but it is never read, instead the variable is being reassigned later in the exit path via label no_dma. Remove the redundant assignment.

2024-10-01spi: spi-fsl-lpspi: Some calculation improvementsMark Brown
Merge series from Stefan Wahren <wahrenst@gmx.net>: This series contains some improvements for spi-fsl-lpspi which are related to the calculations within fsl_lpspi_set_bitrate.
2024-09-30Improve error handling in Rockchip SPI driversMark Brown
Merge series from Dragan Simic <dsimic@manjaro.org>: This is a small series that improves error handling in the probe path of the Rockchip SPI drivers, by using dev_err_probe() properly in multiple places. It also performs a bunch of small, rather trivial code cleanups, to make the code neater and a bit easier to read.

2024-09-30spi: spi_amd: Performance Optimization Patch SeriesMark Brown
Merge series from Raju Rangoju <Raju.Rangoju@amd.com>: AMD SPI controller’s index mode performance is constrained by the hardware limitation of the FIFO queue length. This patch series introduces optimizations to the spi_amd driver, aiming to maximize throughput and enhance overall performance. The changes includes, - Enable SPI dual and quad I/O modes and update SPI-MEM support function to reflect AMD SPI0 hardware capabilities. - Utilize efficient kernel APIs to streamline SPI I/O operations for enhanced performance. - Refine the set tx/rx count functions to optimize SPI I/O throughput. - Minimize the number of data read calls by efficiently retrieving data from FIFO queues, improving SPI I/O efficiency. - Add changes to support AMD HID2 SPI controller and update SPI-MEM support function to reflect AMD HID2 hardware capabilities. - Add changes to set SPI controller address mode before initiating the commands - Add changes to implement HIDDMA read operation support for HID2 SPI controller

2024-09-30spi: Switch back to struct platform_driver::remove()Uwe Kleine-König
After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/spi to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer. The change for the spi-npcm-fiu stands out in the diffstat because the inconsistent formatting style of the platform_driver initializer is fixed to match the other struct initializer in the file.

2024-09-30spi: spi_amd: Add HIDDMA basic read supportRaju Rangoju
SPI index mode has hardware limitation of reading only 64 bytes per transaction due to fixed number of FIFO registers. This constraint leads to performance issues when reading data from NAND/NOR flash devices, as the controller must issue multiple requests to read 64-byte chunks, even if the slave can send up to 2 or 4 KB in single transaction. The AMD HID2 SPI controller supports DMA mode, which allows reading up to 4 KB of data in single transaction. This patch introduces changes to implement HID2 DMA read support for the HID2 SPI controller.

Pull more bcachefs updates from Kent Overstreet: "Assorted minor syzbot fixes, and for bigger stuff: Fix two disk accounting rewrite bugs: - Disk accounting keys use the version field of bkey so that journal replay can tell which updates have been applied to the btree. This is set in the transaction commit path, after we've gotten our journal reservation (and our time ordering), but the BCH_TRANS_COMMIT_skip_accounting_apply flag that journal replay uses was incorrectly skipping this for new updates generated prior to journal replay. This fixes the underlying cause of an assertion pop in disk_accounting_read. - A couple of fixes for disk accounting + device removal. Checking if acocunting replicas entries were marked in the superblock was being done at the wrong point, when deltas in the journal could still zero them out, and then additionally we'd try to add a missing replicas entry to the superblock without checking if it referred to an invalid (removed) device. A whole slew of repair fixes: - fix infinite loop in propagate_key_to_snapshot_leaves(), this fixes an infinite loop when repairing a filesystem with many snapshots - fix incorrect transaction restart handling leading to occasional "fsck counted ..." warnings - fix warning in __bch2_fsck_err() for bkey fsck errors - check_inode() in fsck now correctly checks if the filesystem was clean - there shouldn't be pending logged ops if the fs was clean, we now check for this - remove_backpointer() doesn't remove a dirent that doesn't actually point to the inode - many more fsck errors are AUTOFIX" * tag 'bcachefs-2024-09-28' of git://evilpiepirate.org/bcachefs: (35 commits) bcachefs: check_subvol_path() now prints subvol root inode bcachefs: remove_backpointer() now checks if dirent points to inode bcachefs: dirent_points_to_inode() now warns on mismatch bcachefs: Fix lost wake up bcachefs: Check for logged ops when clean bcachefs: BCH_FS_clean_recovery bcachefs: Convert disk accounting BUG_ON() to WARN_ON() bcachefs: Fix BCH_TRANS_COMMIT_skip_accounting_apply bcachefs: Check for accounting keys with bversion=0 bcachefs: rename version -> bversion bcachefs: Don't delete unlinked inodes before logged op resume bcachefs: Fix BCH_SB_ERRS() so we can reorder bcachefs: Fix fsck warnings from bkey validation bcachefs: Move transaction commit path validation to as late as possible bcachefs: Fix disk accounting attempting to mark invalid replicas entry bcachefs: Fix unlocked access to c->disk_sb.sb in bch2_replicas_entry_validate() bcachefs: Fix accounting read + device removal bcachefs: bch_accounting_mode bcachefs: fix transaction restart handling in check_extents(), check_dirents() bcachefs: kill inode_walker_entry.seen_this_pos ...

2024-09-28Reduce Coccinelle choices in string_choices.cocciJulia Lawall
The isomorphism neg_if_exp negates the test of a ?: conditional, making it unnecessary to have an explicit case for a negated test with the branches inverted. At the same time, we can disable neg_if_exp in cases where a different API function may be more suitable for a negated test. Finally, in the non-patch cases, E matches an expression with parentheses around it, so there is no need to mention () explicitly in the pattern. The () are still needed in the patch cases, because we want to drop them, if they are present. Signed-off-by: Julia Lawall <Julia.Lawall@inria.fr>
