Subject: [PATCH v5 1/2] dt-bindings: mmc: Add full-pwr-cycle-in-suspend property
Date: Tue, 7 Jul 2020 20:58:41 +0900 [thread overview]
Message-ID: <1594123122-13156-2-git-send-email-yoshihiro.shimoda.uh@renesas.com> (raw)
In-Reply-To: <1594123122-13156-1-git-send-email-yoshihiro.shimoda.uh@renesas.com>
The commit 5a36d6bcdf23 ("mmc: core: Add DT-bindings for
MMC_CAP2_FULL_PWR_CYCLE") added the "full-pwr-cycle" property which
is possible to perform a full power cycle of the card at any time.
However, some environment (like r8a77951-salvator-xs) is possible
to perform a full power cycle of the card in suspend via firmware
(PSCI on arm-trusted-firmware). So, add a new property for such
environment.
