  - Ram: 512MB (4x Nanya NT5TU128M8GE-AC)
  - NAND Flash: 256MB (Samsung 216 K9F2G08U0C)
  - Lan: 1x GBE (Marvell 88E1116R-NNC1)
  - Storage: 2x SATA HDD 3.5" Slot
  - USB: 2x USB 2.0 port
  - Console: Internal J3 connector (1: Vcc, 2: Rx, 3: Tx, 4: GND)
  - LEDs: 13x GPIO controlled
  - Buttons: 2x GPIO controlled

Hi Pawel

Thanks for adding the mvebu Maintainers to the list of recipients.

One more process point. It would be normal to set the To: to whoever
you think should actually accept this patch. There are a lot of
Maintainers listed in Cc: so actually pointing a finger at somebody
can help.

Gregory will be the person to actually take this patch.

Thanks for adding a comment. So you need something like a PWM driving
it? Have you tried playing with drivers/input/misc/pwm-beeper.c ?
Some of the mvebu family have a simple PWM functionality as part of
the GPIO controller. I don't remember if kirkwood has this.

I used get_maintainer script. But I will pick manually addresses for cc.

It use a PWM device. Driver gpio-pwm isn't accepted in mainline so far.

Kirkwood have very simple blink mode only: GPIO pin make visible blinks.

[Goes and looks at the datasheet]

Yes, Kirkwood has fixed rate blinking. It is the later generation of
devices which have true PWM capabilities.

Think about adding chassis thermal zone for this sensor,

I suppose you don't have any active control of cooling (fan)?
This often sits on GPIO...

In that case just add a critical temperature so it can't burn
down the house.

See:
arch/arm/boot/dts/gemini-dlink-dns-313.dts
node thermal-zones {} for an example of how to do this
quick and easy. You need CONFIG_THERMAL and
CONFIG_THERMAL_HWMON for this to work.

Hi Linus,
It has a fan controlled by the lm63: PWM controller. But the fan blows
only on disks, board temperature won't change even when PWM = 100%.
It should be controlled by hdd temperature.

Patch it's merged now, I will add critical temperatures in a separate patch.

Aha it is one of those combo things, sorry for my ignorance.

We have a way to even monitor the temperature of individual hard disks
these days and I create a thermal zone and use it here to control a fan
in this DTS:
