[PATCH v3 0/5] Fix a trivial typo and support rk3228/rk3399 SoCs for thermal driver.

[PATCH v3 0/5] Fix a trivial typo and support rk3228/rk3399 SoCs for thermal driver.

[Caesar Wang]

This series pacthes to support the next soc for this thermal driver.
I don't add the dts thermal data since these SoCs have *_not_* land
in this mainline. I believe these SoCs dts will land in this mainline
lately,
then I will add the thermal data for Heiko.

This series patches can apply into Eduardo branch.
https://git.kernel.org/cgit/linux/kernel/git/evalenti/linux-soc-thermal.git

Also, this series pacthes have built on github branch.
https://github.com/rockchip-linux/kernel/commits/develop4.4

PATCH[1/5]:
That's bit ugly typo, sorry for sending again :(.

PATCH[2/5]:
To fix a build warning came from Dan Carpenter report smatch check,
Thanks. :)

PATCH[3/5]:
Add the rk3228/rk3399 SoCs compatible for dt-bindings.

PATCH[4/5]:
Add the rk3228 SoCs for thermal driver.

PATCH[5/5]:
Add the rk3399 SoCs for thermal driver based on PATCH[4/5].

I'd appreciate if someone have free time to review that. :)


Changes in v3:
- As Brian comments on https://patchwork.kernel.org/patch/7580661/,
  let's remove the impossible condition.

Changes in v2:
- As Heiko comments, move to documenting the fields in the header
  instead of inside the table.

Changes in v1:
- Search more trivial typo for me.
- As Heiko comments, fix a copy incorrect name.
- Add a Acked from Rob.
- fix a irq ack is similar with RK3228 SoCs.

[PATCH v3 2/5] thermal: rockchip: fix a impossible condition caused by the warning

[Caesar Wang]

As the Dan report the smatch check the thermal driver warning:
drivers/thermal/rockchip_thermal.c:551 rockchip_configure_from_dt()
warn: impossible condition '(thermal->tshut_temp > ((~0 >> 1))) =>
(s32min-s32max > s32max)'

Let's we remove the imposssible condition Since the Temperature is
currently represented as int not long in the thermal driver.

Fixes: commit 437df2172e8d

Well, that is not entirely correct. The value that we read from DT is
u32, but we convert it down to int. I believe you want to move the check
up so that you do:

	} else if (tshut_temp > INT_MAX) {
		dev_err(dev, "Invalid tshut temperature specified: %d\n",
			thermal->tshut_temp);
		return -ERANGE;
	} else {
		thermal->tshut_temp = shut_temp;
	}

Thanks.

Do we really account for the possibility of sizeof(int) < sizeof(u32)?

EDIT: A bit after writing the above line, I notice my error, but in case
anyone else is thinking the same thing... I guess you're referring to
the sign bit, since we're casting unsigned to signed.

Okay,
that's seem the following wll be resonable since the checkcode is a warning.

if (of_property_read_u32(np, "rockchip,hw-tshut-temp", &shut_temp)) {
         dev_warn(dev,
              "Missing tshut temp property, using default %d\n",
              thermal->chip->tshut_temp);
         thermal->tshut_temp = thermal->chip->tshut_temp;
     } else {
         if (tshut_temp > INT_MAX) {
             dev_err(dev, "Invalid tshut temperature specified: %d\n",
                 tshut_temp);
             return -ERANGE;
         }
         thermal->tshut_temp = shut_temp;
     }

[PATCH v3 5/5] thermal: rockchip: Support the RK3399 SoCs in thermal driver

[Caesar Wang]

The RK3399 SoCs have two Temperature Sensors, channel 0 is for CPU.
channel 1 is for GPU.
