  • 51c26a8c4   MLK-23165-22 nxp_tmu: Update TMU thermal driver to support imx8mp ... Browse Code »

    Update TMU driver for imx8mp thermal which has two probes and supports
    temperature range from -40 to 125. The driver still uses default 1p HW
    calibration at 25C and loads calibration parameters from fuse.

  • febffa35a   MLK-21019 TMU: Check the TEMP range for iMX8MM ... Browse Code »

    On iMX8MM, the V flag in TRISTR register only reflect the state of SNSR
    value, not the calibrated TEMP value. So checking this flag is not
    reliable. Per IC suggestion, change to read the TEMP/AVG_TEMP directly
    and check whether it in valid range 10-125C.

  • 0581e51ff   MLK-20966 TMU: Fix for temperature out of range ... Browse Code »

    When the temperature is out of sensor's range, the Valid bit won't be
    set in TRITSR register. So the polling loop won't go out.

    Change the codes to retry 10 times with 100ms interval for the Valid bit.
    If the timeout, we give a warning for the invalid data.

    Since imx8mm TMU needs to load some registers from fuse, this is arch
    dependent operation and may vary on different platforms. So add
    a interface for arch level initialization.

    The analog sensors on iMX8MM are new, used for 14LPP process. So the
    Temperature Sensor Monitoring Unit (TMU) has some change accordingly.
    We use version 2 in TMU driver to represent the new TMU, so the one driver
    can service for both MQ and MM.

  • 83d290c56   SPDX: Convert all of our single license tags to Linux Kernel style ... Browse Code »
    56

    When U-Boot started using SPDX tags we were among the early adopters and
    there weren't a lot of other examples to borrow from. So we picked the
    area of the file that usually had a full license text and replaced it
    with an appropriate SPDX-License-Identifier: entry. Since then, the
    Linux Kernel has adopted SPDX tags and they place it as the very first
    line in a file (except where shebangs are used, then it's second line)
    and with slightly different comment styles than us.

    In part due to community overlap, in part due to better tag visibility
    and in part for other minor reasons, switch over to that style.

    This commit changes all instances where we have a single declared
    license in the tag as both the before and after are identical in tag
    contents. There's also a few places where I found we did not have a tag
    and have introduced one.

  • 4fac41716   imx: thermal: update imx6 thermal driver according new equation ... Browse Code »

    >From IC guys:
    "
    After a thorough accuracy study of the Temp sense circuit,
    we found that with our current equation, an average part can
    read 7 degrees lower than a known forced temperature.
    We also found out that the standard variance was around 2C;
    which is the tightest distribution that we could create.
    We need to change the temp sense equation to center the average
    part around the target temperature.
    "

    New equation:
    Tmeas = (Nmeas - n1) / slope + t1 + offset
    n1= fused room count
    t1= 25
    offset=3.580661
    slope= 0.4148468 – 0.0015423*n1

    According the new equation, update the thermal driver.
    c1 and c2 changed to u64 type and update comments.

  • be56de6f3   thermal: imx_thermal: increase critical temperature threshold ... Browse Code »

    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...

  • 7267c925b   thermal: imx_thermal: Do not display calibration data ... Browse Code »

    Printing the calibration data on every boot does not provide really useful
    information:

    U-Boot 2015.01-rc1-18266-ge7eb277 (Nov 24 2014 - 11:29:51)

    CPU: Freescale i.MX6Q rev1.2 at 792 MHz
    CPU: Thermal calibration data: 0x5d85067d
    CPU: Temperature 33 C
    Reset cause: POR
    Board: MX6-SabreSD

    Do not display the calibration data in order to have a cleaner boot log.
