From bfc43a9c0ce5f3fcf98c972d7b7f21a742b7c957 Mon Sep 17 00:00:00 2001 From: Srinivas Kandagatla Date: Thu, 8 Jun 2023 13:53:10 +0100 Subject: [PATCH] dt-bindings: clock: Add LPASSCC and reset controller for SC8280XP The LPASS (Low Power Audio Subsystem) clock controller provides reset support when it is under the control of Q6DSP. Add support for those resets and adds IDs for clients to request the reset.
