From fd712118aa1aa758da1fd1546b3f8a1b00e42cbc Mon Sep 17 00:00:00 2001 From: Mantas Pucka Date: Tue, 23 Jan 2024 11:26:09 +0200 Subject: [PATCH] clk: qcom: gcc-ipq6018: add qdss_at clock needed for wifi operation Without it system hangs upon wifi firmware load. It should be enabled by remoteproc/wifi driver. Bindings already exist for it, so add it based on vendor code.
