Subject: [PATCH v3 06/18] mux: mmio: add resume support
Date: Thu, 15 Feb 2024 16:17:51 +0100 [thread overview]
Message-ID: <20240102-j7200-pcie-s2r-v3-6-5c2e4a3fac1f@bootlin.com> (raw)
In-Reply-To: <20240102-j7200-pcie-s2r-v3-0-5c2e4a3fac1f@bootlin.com>
From: Théo Lebrun <theo.lebrun@bootlin.com>
No need to save something during the suspend stage, as the mux core has an
internal cache to store the state of muxes.
This cache is used by mux_chip_resume() to restore all muxes.
