From 54c16b522e00583ba1151501286b0cf4c91e08c3 Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Tue, 12 Jul 2022 16:42:42 +0200 Subject: [PATCH] dt-bindings: mmc: sdhci-msm: constrain reg-names per variants The entries in arrays must have fixed order, so the bindings and Linux driver expecting various combinations of 'reg' addresses was never actually conforming to guidelines. The 'core' reg entry is valid only for SDCC v4 and lower, so disallow it in SDCC v5. SDCC v4 supports CQE and ICE, so allow them, even though the qcom,sdhci-msm-v4 compatible is used also for earlier SoCs with SDCC v2 or v3, so it is not entirely accurate.
