arm: imx9: Fix LPCG number in ccm_reg structure

2025-09-21T12:08:50Z

The LPCG number on iMX93 and iMX91 is 127 not 122. The wrong value is used in ccm_reg structure and Coverity reports several issues as out-of-bounds write. Signed-off-by: Ye Li Reviewed-by: Peng Fan

imx9: scmi: add i.MX95 SoC and clock related code

2025-05-03T19:55:32Z

This patch adds i.MX95 SoC and clock related code. Because they are based on SCMI, put them in the scmi subfolder. Signed-off-by: Alice Guo Signed-off-by: Frank Li Signed-off-by: Ji Luo Signed-off-by: Jindong Yue Signed-off-by: Peng Fan Signed-off-by: Ranjani Vaidyanathan Signed-off-by: Ye Li

imx: Add iMX91 support

2024-12-07T12:07:04Z

iMX91 is reduced part from iMX93 with part number: i.MX9131/11/01 It removed A55_1, M33, MIPI DSI, LVDS, etc. i.MX9131: - Support 2.4GT/s DDR and HWFFC at 1.2GT/s i.MX9121: - A55 at 800Mhz and DDR at 1600MTS, with low drive mode. i.MX9111: - Support 1.6GT/s DDR and HWFFC at 800MT/s i.MX9101: - Support 800Mhz ARM clock - Support 1.6GT/s DDR and HWFFC at 800MT/s - No parallel display, eQOS, flexcan Updated Clock/Container/CPU and etc for i.MX91 Signed-off-by: Ye Li Signed-off-by: Peng Fan

imx9: clock: Update clock init function and sequence

2024-09-19T03:12:41Z

Since we use SPEED GRADE fuse to set A55 frequency, remove the set_arm_core_low_drive_clk function which has hard coded frequency. And adjust clock_init called sequence and split it to early and late functions. Set the authen register in early function, because CCF driver checks NS bit. Set bus and core clock in late function, because the fuse read and SoC type/rev depend on ELE. Reviewed-by: Peng Fan Signed-off-by: Ye Li Signed-off-by: Peng Fan
