From: Vadim Pasternak Date: Tue, 22 Aug 2023 11:34:42 +0000 (+0000) Subject: platform: mellanox: mlx-platform: Modify power off callback X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=75e09ab42066b93ec30ba1a9d5d252e40916320a;p=linux.git platform: mellanox: mlx-platform: Modify power off callback Extend platform power off callback with kernel_halt() call. When powering off, the process involves setting a halt bit in the register space, which is then activated after a certain delay and power off auxiliary power. By invoking `kernel_halt()` within this timeframe, the intention is to facilitate a clean system power-off sequence.
