From e343d34a9c912fc5c321e2a9fbc02e9dc9534ade Mon Sep 17 00:00:00 2001 From: Jack Yu Date: Mon, 7 Jun 2021 17:22:35 -0500 Subject: [PATCH] ASoC: rt715-sdca: fix clock stop prepare timeout issue MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Fix clock stop prepare timeout issue (#2853). The trigger of internal circuit which belong to “SDCA preset stuffs” was not set correctly in previous driver, which could block clock_stop_preparation state. Add the correct register setting to fix it.
