When sim_enet_root_clk is ready, clk_core_reparent_orphans_nolock will set enet_qos_root_clk parent to sim_enet_root_clk. Because CLK_OPS_PARENT_ENABLE is set, sim_enet_root_clk will be enabled and disabled during the enet_qos_root_clk reparent phase. All the above are correct.

It fails on "clk_periph_timer" - which uses a different parent, that it tries to find using the macro: \#define PARENT_CLK(PARENT) (&mpfs_cfg_clks[CLK_##PARENT].cfg.hw) If parent is RTCREF, so the macro becomes: &mpfs_cfg_clks[33].cfg.hw which is well beyond the end of the array. Amazingly, builds with GCC 11.1 see no problem here, booting correctly and hooking the parent up etc. Builds with clang-15 do not, with the above panic. Change the macro to use specific offsets depending on the parent rather than the dt-binding's clock IDs.

Although imx_clk_hw_gate4_flags is used here, it not strictly match i.MX93. i.MX93 has such design: - LPCG_DIRECT use BIT0 as on/off gate when LPCG_AUTHEN CPU_LPM is 0 - LPCG_LPM_CUR use BIT[2:0] as on/off gate when LPCG_AUTHEN CPU_LPM is 1 The current implementation suppose CPU_LPM is 0, and use LPCG_DIRECT BIT[1:0] as on/off gate. Although BIT1 is touched, actually BIT1 is reserved. And imx_clk_hw_gate4_flags use mask 0x3 to determine whether the clk is enabled or not, but i.MX93 LPCG only use BIT0 to control when CPU_LPM is 0. So clk disabled unused during kernel boot not able to gate off the unused clocks. To match i.MX93 LPCG, introduce imx93_clk_gate.

From 855ae87a2073ebf1b395e020de54fdf9ce7d166f Mon Sep 17 00:00:00 2001 From: Lin Yujun Date: Wed, 14 Sep 2022 11:32:06 +0800 Subject: clk: imx: scu: fix memleak on platform_device_add() fails No error handling is performed when platform_device_add() fails. Add error processing before return, and modified the return value.
