Subject: [PATCH v4 07/10] dt-bindings: mfd: samsung,s2mps11: convert to dtschema
Date: Fri,  8 Oct 2021 13:39:29 +0200	[thread overview]
Message-ID: <20211008113931.134847-4-krzysztof.kozlowski@canonical.com> (raw)
In-Reply-To: <20211008113723.134648-1-krzysztof.kozlowski@canonical.com>

Convert the MFD part of Samsung S2MPS11/S2MPS13/S2MPS14/S2MPS15/S2MPU02
family of PMICs to DT schema format.  Previously the bindings were
mostly in mfd/samsung,sec-core.txt.

The conversion copies parts of description from existing bindings
therefore the license is not changed from GPLv2.

+  This is a part of device tree bindings for S2M and S5M family of Power
+  Management IC (PMIC).
+
+  The Samsung S2MPS11/13/14/15 and S2MPU02 is a family of Power Management IC
+  which include voltage and current regulators, RTC, clock outputs and other
+  sub-blocks.
