From fd712118aa1aa758da1fd1546b3f8a1b00e42cbc Mon Sep 17 00:00:00 2001

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.
