Subject: [PATCH] dt-bindings: mfd: syscon: Add missing simple syscon compatibles
Date: Tue,  2 Apr 2024 15:24:11 -0500
Message-ID: <20240402202413.757283-1-robh@kernel.org>
Precedence: bulk
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

Add various "simple" syscon compatibles which were undocumented or
still documented with old text bindings.

apm,xgene-csw, apm,xgene-efuse, apm,xgene-mcb, apm,xgene-rb,
fsl,ls1088a-reset, marvell,armada-3700-cpu-misc,
mediatek,mt2712-pctl-a-syscfg, mediatek,mt6397-pctl-pmic-syscfg, and
mediatek,mt8173-pctl-a-syscfg were all undocumented, but are in use
already. Remove the old text binding docs for the others.
