From 2a8d9b371566e798421ef877c5757e2c4a11ad6f Mon Sep 17 00:00:00 2001 From: Tao Zhang Date: Thu, 28 Sep 2023 14:29:35 +0800 Subject: [PATCH] dt-bindings: arm: Add support for DSB element size Add property "qcom,dsb-elem-size" to support DSB(Discrete Single Bit) element for TPDM. The associated aggregator will read this size before it is enabled. DSB element size currently only supports 32-bit and 64-bit.
