2025-03-25cpu: imx8_cpu: Print Speed grade if IMX_TMUAdam Ford
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.

2024-10-18cpu: imx8_cpu: Avoid revision to corrupt device treePeng Fan
U-Boot device tree is padded just after U-Boot proper. After the whole stuff loaded to DRAM space, the device tree area is conflict with BSS region before U-Boot relocation. So any write to BSS area before reloc_fdt will corrupt the device tree. Without the fix, there is issue that “binman_init failed:-2” on i.MX8MP-EVK board. Drop 'revision' and use malloc area in cpu_imx_plat->rev. Signed-off-by: Peng Fan <peng.fan@nxp.com>

2021-02-02common: Drop asm/global_data.h from common headerSimon Glass
Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

2020-12-13dm: treewide: Rename 'platdata' variables to just 'plat'Simon Glass
We use 'priv' for private data but often use 'platdata' for platform data. We can't really use 'pdata' since that is ambiguous (it could mean private or platform data). Rename some of the latter variables to end with 'plat' for consistency. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-12-13dm: treewide: Rename auto_alloc_size members to be shorterSimon Glass
This construct is quite long-winded. In earlier days it made some sense since auto-allocation was a strange concept. But with driver model now used pretty universally, we can shorten this to 'auto'. This reduces verbosity and makes it easier to read. Coincidentally it also ensures that every declaration is on one line, thus making dtoc's job easier. Signed-off-by: Simon Glass <sjg@chromium.org>

2020-05-22cpu: imx8: use intended cpu-thermal device when getting temp valueAnatolij Gustschin
This fixes getting DT alert and critical pdata values in imx_scu_thermal driver. On i.MX8QXP using not initialized alert pdata value resulted in boot hang and endless loop outputting: CPU Temperature (47200C) has beyond alert (0C), close to critical (0C) waiting... While at it, preset CPU type values once to avoid multiple calls of device_is_compatible() for same property.
