power: reset: nvmem-reboot-mode: respect cell size for nvmem_cell_write

2026-03-04T12:19:48+00:00

[ Upstream commit 36b05629226413836cfbb3fbe6689cd188bca156 ] Some platforms expose reboot mode cells that are smaller than an unsigned int, in which cases lead to write failures. Read the cell first to determine actual size and only write the number of bytes the cell can hold.

power: reset: at91-reset: Optimize at91_reset()

2025-06-27T10:07:07+00:00

[ Upstream commit 62d48983f215bf1dd48665913318101fa3414dcf ] This patch adds a small optimization to the low-level at91_reset() function, which includes: - Removes the extra branch, since the following store operations already have proper condition checks. - Removes the definition of the clobber register r4, since it is no longer used in the code.

pwr-mlxbf: extend Kconfig to include gpio-mlxbf3 dependency

2023-10-25T10:03:09+00:00

[ Upstream commit 82f07f1acf417b81e793145c167dd5e156024de4 ] The BlueField power handling driver (pwr-mlxbf.c) provides functionality for both BlueField-2 and BlueField-3 based platforms. This driver also depends on the SoC-specific BlueField GPIO driver, whether gpio-mlxbf2 or gpio-mlxbf3. This patch extends the Kconfig definition to include the dependency on the gpio-mlxbf3 driver, if applicable.
