From 24a4b7855f569ee36b63798c0ca2da4581dec105 Mon Sep 17 00:00:00 2001 From: Srinivas Kandagatla Date: Thu, 23 Mar 2023 11:01:25 +0000 Subject: [PATCH] FROMGIT: ASoC: codecs: lpass: fix the order or clks turn off during suspend The order in which clocks are stopped matters as some of the clock like NPL are derived from MCLK. Without this patch, Dragonboard RB5 DSP would crash with below error: qcom_q6v5_pas 17300000.remoteproc: fatal error received: ABT_dal.c:278:ABTimeout: AHB Bus hang is detected, Number of bus hang detected := 2 , addr0 = 0x3370000 , addr1 = 0x0!!! Turn off fsgen first, followed by npl and then finally mclk, which is exactly the opposite order of enable sequence.
