u-boot.git/drivers/thermal, branch v2016.07

Fix various typos, scattered over the code.

2016-05-06T01:39:26+00:00

Spelling corrections for (among other things):

* environment
* override
* variable
* ftd (should be "fdt", for flattened device tree)
* embedded
* FTDI
* emulation
* controller

imx: mx7: fix the temperature checking for Rev1.1

2016-01-07T16:53:11+00:00

To TO1.0, we can not rely on finish bit to read temperature. But to
TO1.1, the issue was fixed by IC, we can rely on finish bit for
temperature reading for TO1.1.

thermal: imx_thermal: Do not print on error

2015-09-13T08:49:21+00:00

It is not very useful to have the message below on every boot
(especially when we are using early silicon):

U-Boot 2015.10-rc2-23945-g37cf215 (Sep 08 2015 - 14:12:14 -0300)

CPU:   Freescale i.MX6UL rev1.0 792 MHz (running at 396 MHz)
CPU:   Commercial temperature grade (0C to 95C)CPU:   Thermal invalid data, fuse: 0x0
 - invalid sensor device

, so turn the error message into debug level.

thermal: imx_thermal: fix busywait if IMX6 temp <0C

2015-07-10T08:15:19+00:00

The temperature calculation must be typecasted to keep the compiler
from sign extending a negative value prior to division.

This fixes an issue where if the CPU temperature is <0C it will get stuck
in the busywait loop until the CPU heats up to 0C.

thermal:imx_thermal: enter busywait cooling loop when over max CPU temp

2015-07-10T07:23:32+00:00

Remove the check for temperature being within the min/max range and enter the
busywait cooling loop whenever the CPU temperature is over the critical temp.
This fixes the issue where if a board was booted at a temp greater than
the CPU temperature max, it would skip the loop and never indicate or try
to address the overtemp issue.

thermal: imx_thermal: increase critical temperature threshold

2015-05-26T12:21:25+00:00

The CPU temperature grade from OTP is now used to define the critical
threshold at which point we busyloop until we are below, however this
threshold is still too low.

Instead of 20C below the max CPU temperature, change it to 5C defined now
by TEMPERATURE_HOT_DETLA for clarity. Rename 'passive' to 'critical'
as that better defines our use case here. Additionally change the output
of the busyloop message to show the max CPU temperature as well as current.

Before:
CPU Temperature is 101 C, too hot to boot, waiting...
CPU Temperature is 101 C, too hot to boot, waiting...

After:
CPU Temperature (101C) too close to max (105C) waiting...
CPU Temperature (101C) too close to max (105C) waiting...
