The imx8_cpu driver uses the driver model to represent the processor
cores in the dm tree as well as display the processor type and speed
on boot. Currently, the imx8_cpu driver only displays the temperature
grade of the processor if the processor is IMX9, so in order to display
that info, the check in imx8_cpu is changed to check for IMX_TMU
and IMX_TMU is implied for IMX8, IMX8M and IMX9 SoC familes. If
users want to fall back to the older method to display the SoC type
or remove the temperature grade information, they can. Doing this
at the SoC family level reduces the number of duplicated config options
for each board, and was done at the request of the IMX U-Boot custodian.
Any testing on an i.MX8Q or i.MX9 would be appreciated as I don't have
a board that runs either of these platforms.
V3: Added the imply IMX_TMU for the 8M family and added the imply for
CPU and CPU_IMX to IMX8, IMX8M and IMX9 families
V2: Changed the check in imx8_cpu to drop the IMX9 check and instead
imply IMX_TMU in the IMX9 family
Adam Ford (6):
imx: imx9: Imply IMX_TMU
imx: imx8m: Imply IMX_TMU
cpu: imx8_cpu: Print Speed grade if IMX_THERMAL or IMX_TMU
imx: imx8m: Imply CPU_IMX by default
imx: imx8: Imply CPU_IMX by default
imx: imx9: Imply CPU_IMX by default
