From 07f8f060edd759f6f1bbaea3c078fe526f4dcbf9 Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Sun, 4 Dec 2022 10:47:13 +0100 Subject: [PATCH] dt-bindings: mmc: sdhci: document sdhci-caps and sdhci-caps-mask The Linux SDHCI driver core reads 'sdhci-caps' and 'sdhci-caps-mask' properties and few devices already use it (e.g. Qualcomm SM8450), so add them to a shared SDHCI bindings.
