mtd: rawnand: pl353: make sure optimal timings are applied

2026-03-18T17:08:25Z

Timings of the nand are adjusted by pl35x_nfc_setup_interface() but actually applied by the pl35x_nand_select_target() function. If there is only one nand chip, the pl35x_nand_select_target() will only apply the timings once since the test at its beginning will always be true after the first call to this function. As a result, the hardware will keep using the default timings set at boot to detect the nand chip, not the optimal ones. With this patch, we program directly the new timings when pl35x_nfc_setup_interface() is called.

mtd: rawnand: pl353: Fix software ECC support

2026-02-05T18:12:36Z

We need to set also write_page_raw in ecc structure to allow choosing SW ECC instead of HW one, otherwise write operation fail.

mtd: rawnand: pl353: drop unused module alias

The driver has never supported anything but OF probing so drop the unused platform module alias. Signed-off-by: Johan Hovold Signed-off-by: Miquel Raynal

mtd: rawnand: pl353: Use int type to store negative error codes

2025-09-01T13:01:09Z

Change the 'ret' variable from u32 to int in pl35x_nand_probe() to store negative error codes or zero; Storing the negative error codes in unsigned type, doesn't cause an issue at runtime but can be confusing. Additionally, assigning negative error codes to unsigned type may trigger a GCC warning when the -Wsign-conversion flag is enabled. No effect on runtime.

SPI-NAND changes: A load of fixes to Winbond manufacturer driver have been done, plus a structure constification. Raw NAND changes: The GPMI driver has been improved on the power management side. The Davinci driver has been cleaned up. A leak in the Atmel driver plus some typos in the core have been fixed.

mtd: Switch back to struct platform_driver::remove()

2024-10-21T09:58:07Z

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.
