From b1f12a685d459c3fc898b12d0b052acfab2e3018 Mon Sep 17 00:00:00 2001 From: Abel Vesa Date: Mon, 7 Nov 2022 16:50:07 +0800 Subject: [PATCH] clk: imx8mp: Add audio shared gate According to the RM, the CCGR101 is shared for the following root clocks: - AUDIO_AHB_CLK_ROOT - AUDIO_AXI_CLK_ROOT - SAI1_CLK_ROOT - SAI2_CLK_ROOT - SAI3_CLK_ROOT - SAI5_CLK_ROOT - SAI6_CLK_ROOT - SAI7_CLK_ROOT - PDM_CLK_ROOT IMX8MP_CLK_AUDIO_ROOT is same as AUDIO_AHB_CLK_ROOT which can avoid break any users.
