From d0804085c5a7feb557bd3219777b51f5598dfdc6 Mon Sep 17 00:00:00 2001 From: Moudy Ho Date: Fri, 10 Jun 2022 14:34:18 +0800 Subject: soc: mediatek: mutex: add common interface for modules setting In order to allow multiple modules to operate MUTEX hardware through a common interfrace, two flexible indexes "mtk_mutex_mod_index" and "mtk_mutex_sof_index" need to be added to replace original component ID so that like DDP and MDP can add their own MOD table or SOF settings independently. In addition, 2 generic interface "mtk_mutex_write_mod" and "mtk_mutex_write_sof" have been added, which is expected to replace the "mtk_mutex_add_comp" and "mtk_mutex_remove_comp" pair originally dedicated to DDP in the future.
