cpu: imx8_cpu: Fix CPU segment information print

2026-06-04T20:25:22Z

Should not use CONFIG_IMX_TMU to determine the print of CPU market segment information. Only iMX8 platforms don't have segment fuse. And there is no extended commercial part on iMX9 (91/93/94/95), fix it to extended industrial. Signed-off-by: Ye Li

cpu: imx952: Add i.MX952 support

2026-03-16T21:44:00Z

This patch is used to add the imx type string of i.MX952 so that the i.MX952 CPU info can be printed. Signed-off-by: Alice Guo Reviewed-by: Peng Fan

treewide: Clean up DECLARE_GLOBAL_DATA_PTR usage

2026-02-17T19:50:22Z

Remove DECLARE_GLOBAL_DATA_PTR from files where gd is not used, and drop the unnecessary inclusion of asm/global_data.h. Headers should be included directly by the files that need them, rather than indirectly via global_data.h.

thermal: Convert .get_temp() return value to millicelsius

2025-10-08T19:54:59Z

Linux kernel .get_temp() callback reports values in millicelsius, U-Boot currently reports them in celsius. Align the two and report in millicelsius. Update drivers accordingly. Update callsites that use thermal_get_temp() as well. The 'temperature' command now reports temperature in millicelsius as well, with additional accuracy. This changes command line ABI slightly.

cpu: imx94: Add support for i.MX94 in get_imx_type_str()

2025-09-26T12:51:21Z

Add a case for i.MX94 to return the correct string identifier in the get_imx_type_str() function. This ensures proper CPU type reporting for i.MX94 platforms. Signed-off-by: Alice Guo

cpu: imx8_cpu: Provide default temperatures

2025-08-07T11:15:00Z

Add setting default temperatures to the weak version of get_cpu_temp_grade so these values will not be used uninitialised. This issue was found by Smatch. Signed-off-by: Andrew Goodbody

cpu: imx8_cpu: Print Speed grade if IMX_TMU

2025-03-25T11:32:16Z

Much of the data that is display by imx8_cpu.c is also displayed from arch/arm/mach-imx/cpu.c, except the temperature grade and active temperature are only displayed when SoC is an i.MX9. Since IMX9 now implies IMX_TMU, change this to check for IMX_TMU in the same way it's done in mach-imx/cpu.c to enable displaying this information for any SoC with either of this config enabled. Since additional text may appear due to this commit, remove the extra space in the message displaying the temperature grade.
