From 75c6f1a0191a8d0c5c8e9cc5d33daa47d88783e1 Mon Sep 17 00:00:00 2001 From: Jacky Bai Date: Tue, 14 Sep 2021 14:52:04 +0800 Subject: [PATCH] clk: imx: Add 'CLK_SET_RATE_NO_REPARENT' for composite-7ulp For the imx_composite-7ulp clock type, The clock parent should be changed explicitly by end user of this clock, if the the 'CLK_SET_RATE_NO_REPARENT' flag is not set, when user want to set a clock frequency that can NOT get from HW accurately, then the clock's parent will be switch to another clock parent sometimes. This is NOT what we expected and introduced some additional debug effort, so add the 'CLK_SET_RATE_NO_REPARENT' to avoid such unexpected result.
