Subject: [PATCH v2 1/2] bus: sunxi-rsb: Remove shutdown callback
Date: Sun, 6 Nov 2022 23:21:59 -0600 [thread overview]
Message-ID: <20221107052201.65477-2-samuel@sholland.org> (raw)
In-Reply-To: <20221107052201.65477-1-samuel@sholland.org>
Shutting down the RSB controller prevents communicating with a PMIC
inside pm_power_off(), so it breaks system poweroff on some boards.
Reported-by: Ivaylo Dimitrov <ivo.g.dimitrov.75@gmail.com>
Tested-by: Ivaylo Dimitrov <ivo.g.dimitrov.75@gmail.com>
Acked-by: Jernej Skrabec <jernej.skrabec@gmail.com>
Fixes: 843107498f91 ("bus: sunxi-rsb: Implement suspend/resume/shutdown callbacks")
