2024-12-24mtd: rawnand: davinci: Implement setup_interface() operationBastien Curutchet
The setup_interface() operation isn't implemented. It forces the driver to use the ONFI mode 0, though it could use more optimal modes. Implement the setup_interface() operation. It uses the aemif_set_cs_timings() function from the AEMIF driver to update the chip select timings. The calculation of the register's contents is directly extracted from §20.3.2.3 of the DaVinci TRM [1] MAX_TH_PS and MAX_TSU_PS are the worst case timings based on the Keystone2 and DaVinci datasheets.

2024-12-05mtd: rawnand: arasan: Fix double assertion of chip-selectMaciej Andrzejewski
When two chip-selects are configured in the device tree, and the second is a non-native GPIO, both the GPIO-based chip-select and the first native chip-select may be asserted simultaneously. This double assertion causes incorrect read and write operations. The issue occurs because when nfc->ncs <= 2, nfc->spare_cs is always initialized to 0 due to static initialization. Consequently, when the second chip-select (GPIO-based) is selected in anfc_assert_cs(), it is detected by anfc_is_gpio_cs(), and nfc->native_cs is assigned the value 0. This results in both the GPIO-based chip-select being asserted and the NAND controller register receiving 0, erroneously selecting the native chip-select. This patch resolves the issue, as confirmed by oscilloscope testing with configurations involving two or more chip-selects in the device tree.

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/mtd 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.

git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Pull non-MM updates from Andrew Morton: "Many singleton patches - please see the various changelogs for details. Quite a lot of nilfs2 work this time around. Notable patch series in this pull request are: - "mul_u64_u64_div_u64: new implementation" by Nicolas Pitre, with assistance from Uwe Kleine-König. Reimplement mul_u64_u64_div_u64() to provide (much) more accurate results. The current implementation was causing Uwe some issues in the PWM drivers. - "xz: Updates to license, filters, and compression options" from Lasse Collin. Miscellaneous maintenance and kinor feature work to the xz decompressor. - "Fix some GDB command error and add some GDB commands" from Kuan-Ying Lee. Fixes and enhancements to the gdb scripts. - "treewide: add missing MODULE_DESCRIPTION() macros" from Jeff Johnson. Adds lots of MODULE_DESCRIPTIONs, thus fixing lots of warnings about this. - "nilfs2: add support for some common ioctls" from Ryusuke Konishi. Adds various commonly-available ioctls to nilfs2. - "This series fixes a number of formatting issues in kernel doc comments" from Ryusuke Konishi does that. - "nilfs2: prevent unexpected ENOENT propagation" from Ryusuke Konishi. Fix issues where -ENOENT was being unintentionally and inappropriately returned to userspace. - "nilfs2: assorted cleanups" from Huang Xiaojia. - "nilfs2: fix potential issues with empty b-tree nodes" from Ryusuke Konishi fixes some issues which can occur on corrupted nilfs2 filesystems. - "scripts/decode_stacktrace.sh: improve error reporting and usability" from Luca Ceresoli does those things" * tag 'mm-nonmm-stable-2024-09-21-07-52' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm: (103 commits) list: test: increase coverage of list_test_list_replace*() list: test: fix tests for list_cut_position() proc: use __auto_type more treewide: correct the typo 'retun' ocfs2: cleanup return value and mlog in ocfs2_global_read_info() nilfs2: remove duplicate 'unlikely()' usage nilfs2: fix potential oob read in nilfs_btree_check_delete() nilfs2: determine empty node blocks as corrupted nilfs2: fix potential null-ptr-deref in nilfs_btree_insert() user_namespace: use kmemdup_array() instead of kmemdup() for multiple allocation tools/mm: rm thp_swap_allocator_test when make clean squashfs: fix percpu address space issues in decompressor_multi_percpu.c lib: glob.c: added null check for character class nilfs2: refactor nilfs_segctor_thread() nilfs2: use kthread_create and kthread_stop for the log writer thread nilfs2: remove sc_timer_task nilfs2: do not repair reserved inode bitmap in nilfs_new_inode() nilfs2: eliminate the shared counter and spinlock for i_generation nilfs2: separate inode type information from i_state field nilfs2: use the BITS_PER_LONG macro ...

2024-09-09mtd: rawnand: mtk: Fix init error pathMiquel Raynal
Reviewing a series converting the for_each_chil_of_node() loops into their _scoped variants made me realize there was no cleanup of the already registered NAND devices upon error which may leak memory on systems with more than a chip when this error occurs. We should call the _nand_chips_cleanup() function when this happens.

2024-09-06mtd: rawnand: mtk: Factorize out the logic cleaning mtk chipsMiquel Raynal
There are some un-freed resources in one of the error path which would benefit from a helper going through all the registered mtk chips one by one and perform all the necessary cleanup. This is precisely what the remove path does, so let's extract the logic in a helper. There is no functional change.

2024-09-06mtd: rawnand: meson: Fix typo in function nameMiquel Raynal
There is a reason why sometime we write "NAND chip" with an 's'. It usually means several chips can be managed by the same controller. So when initializing a single chip at a time, the wording "chip" must be used, otherwise when talking about all the chips managed by the controller, we want to use "chips". Fix the function name to clarify the meson_nfc_nand_chip*s*_cleanup() helper intend.
