[V2,2/2] thermal: imx: add i.MX7 thermal sensor support

Commit Message

Anson Huang Jan. 26, 2018, 8:09 a.m. UTC

This patch adds i.MX7 thermal sensor support, most
of the i.MX7 thermal sensor functions are same with
i.MX6 except the registers offset/layout, so we move
those registers offset/layout definitions to soc data
structure.

i.MX7 uses single calibration data @25C, the calibration
data is located at OCOTP offset 0x4F0, bit[17:9], the
formula is as below:

Tmeas = (Nmeas - n1) + 25; n1 is the fuse value for 25C.

changes since V1:
	1. remove MX7 operation in imx_set_panic_temp since MX7 does NOT support it;
	2. add const for struct imx_thermal_data in imx_init_from_tempmon_data;
	3. add .low_alarm_ctrl for MX6SX and use it in .probe function.
