Subject: [PATCH v11 1/6] dt-bindings: mmc: Extend keep-power-in-suspend beyond SDIO
Date: Fri, 30 Oct 2026 14:10:28 -0400 [thread overview]
Message-ID: <20261030181034.3811225-2-kamal.dasu@broadcom.com> (raw)
In-Reply-To: <20261030181034.3811225-1-kamal.dasu@broadcom.com>
keep-power-in-suspend is currently documented as SDIO-only, but the
requirement it describes -- preserving card power across a
suspend/resume cycle -- applies just as well to any card type. Drop
the SDIO-only restriction so eMMC and SD platforms can use it too.
