From 8122dc58cb3e3ea1ee10d44e37bf1cd0a4374116 Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Sat, 17 Jul 2021 15:09:24 +0300 Subject: bus: ti-sysc: Add quirk for OMAP4 McASP to disable SIDLE mode The McASP module in OMAP4 does not work if the SIDLE mode is enabled, most like due to module integration issue that the signaling is not working correctly. Add a quirk for the module to select only NOIDLE mode when it is in use.
