[PATCH V4 2/2] thermal: imx: add i.MX7 thermal sensor support
Anson Huang
Anson.Huang at nxp.com
Sat Feb 24 00:02:49 PST 2018
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 V3:
use "fsl,imx7d-tempmon" instead of "fsl,imx7-tempmon" as compatible string;
rebase to latest 4.16-rc2;
improve local variable definition sequence.

* Temperature Monitor (TEMPMON) on Freescale i.MX SoCs
Required properties:
-- compatible : "fsl,imx6q-tempmon" for i.MX6Q, "fsl,imx6sx-tempmon" for i.MX6SX.
- i.MX6SX has two more IRQs than i.MX6Q, one is IRQ_LOW and the other is IRQ_PANIC,
+- compatible : must be one of following:
+ - "fsl,imx6q-tempmon" for i.MX6Q,
+ - "fsl,imx6sx-tempmon" for i.MX6SX,
+ - "fsl,imx7d-tempmon" for i.MX7S/D.
+- interrupts : the interrupt output of the controller:
+ i.MX6Q has one IRQ which will be triggered when temperature is higher than high threshold,
+ i.MX6SX and i.MX7S/D have two more IRQs than i.MX6Q, one is IRQ_LOW and the other is IRQ_PANIC,
when temperature is below than low threshold, IRQ_LOW will be triggered, when temperature
is higher than panic threshold, system will auto reboot by SRC module.
- fsl,tempmon : phandle pointer to system controller that contains TEMPMON
