[PATCH v3 0/6] Add support for IR transmitters

[Andi Shyti]

Hi,

The main goal is to add support in the rc framework for IR
transmitters, which currently is only supported by lirc but that
is not the preferred way.

The last patch adds support for an IR transmitter driven by
the MOSI line of an SPI controller, it's the case of the Samsung
TM2(e) board which support is currently ongoing.

Thanks Sean for your prompt reviews.

Changelog from version 1:

The RFC is now PATCH. The main difference is that this version
doesn't try to add the any bit streaming protocol and doesn't
modify any LIRC interface specification.

patch 1: updates all the drivers using rc_allocate_device
patch 2: fixed errors and warning reported from the kbuild test
         robot
patch 5: this patch has been dropped and replaced with a new one
         which avoids waiting for transmitters.
patch 6: added new properties to the dts specification
patch 7: the driver uses the pulse/space input and converts it to
         a bit stream.


Changelog from version 2:

The original patch number 5 has been abandoned because it was not
bringing much benenfit.

patch 1: rebased on the new kernel.
patch 3: removed the sysfs attribute protocol for transmitters
patch 5: the binding has been moved to the leds section instead
         of the media. Fixed all the comments from Rob
patch 6: fixed all the comments from Sean added also Sean's
         review.

[PATCH v3 1/6] [media] rc-main: assign driver type during allocation

[Andi Shyti]

The driver type can be assigned immediately when an RC device
requests to the framework to allocate the device.

This is an 'enum rc_driver_type' data type and specifies whether
the device is a raw receiver or scancode receiver. The type will
be given as parameter to the rc_allocate_device device.

Change accordingly all the drivers calling rc_allocate_device()
so that the device type is specified during the rc device
allocation. Whenever the device type is not specified, it will be
set as RC_DRIVER_SCANCODE which was the default '0' value.

[PATCH v3 3/6] [media] rc-core: add support for IR raw transmitters

[Andi Shyti]

IR raw transmitter driver type is specified in the enum
rc_driver_type as RC_DRIVER_IR_RAW_TX which includes all those
devices that transmit raw stream of bit to a receiver.

The data are provided by userspace applications, therefore they
don't need any input device allocation, but still they need to be
registered as raw devices.

The ir-spi is a simple device driver which supports the
connection between an IR LED and the MOSI line of an SPI device.

The driver, indeed, uses the SPI framework to stream the raw data
provided by userspace through an rc character device. The chardev
is handled by the LIRC framework and its functionality basically
provides:

 - write: the driver gets a pulse/space signal and translates it
   to a binary signal that will be streamed to the IR led through
   the SPI framework.
 - set frequency: sets the frequency whith which the data should
   be sent. This is handle with ioctl with the
   LIRC_SET_SEND_CARRIER flag (as per lirc documentation)
 - set duty cycle: this is also handled with ioctl with the
   LIRC_SET_SEND_DUTY_CYCLE flag. The driver handles duty cycles
   of 50%, 60%, 70%, 75%, 80% and 90%, calculated on 16bit data.

The character device is created under /dev/lircX name, where X is
and ID assigned by the LIRC framework.

Example of usage:

        fd = open("/dev/lirc0", O_RDWR);
        if (fd < 0)
                return -1;

        val = 608000;
        ret = ioctl(fd, LIRC_SET_SEND_CARRIER, &val);
        if (ret < 0)
                return -1;

	val = 60;
        ret = ioctl(fd, LIRC_SET_SEND_DUTY_CYCLE, &val);
        if (ret < 0)
                return -1;

        n = write(fd, buffer, BUF_LEN);
        if (n < 0 || n != BUF_LEN)
                ret = -1;

        close(fd);

Hi Andi,

at least patches 1 and 2 conflict with recent extensions. See commits
ddbf7d5a698c "rc: core: add managed versions of rc_allocate_device and
rc_register_device" and b6f3ece38733 "[media] rc: nuvoton: use managed
versions of rc_allocate_device and rc_register_device".

It would be good if you could rebase your patch set on top of the
latest master branch of media tree. Most likely you will have to make
changes to the recently introduced managed versions of
rc_allocate_device and rc_register_device.

Rgds, Heiner

Re: [PATCH v3 5/6] Documentation: bindings: add documentation for ir-spi device driver

[Jacek Anaszewski]

Hi Andi,

Only DT bindings of LED class drivers should be placed in
Documentation/devicetree/bindings/leds. Please move it to the
media bindings.

Thanks,
Jacek Anaszewski

that's where I placed it first, but Rob asked me to put it in the
LED directory and Cc the LED mailining list.

That's the discussion of the version 2:

https://lkml.org/lkml/2016/9/12/380

Rob, Jacek, could you please agree where I can put the binding?

Thanks,
Andi

I'm not sure if this is a good approach. I've noticed also that
backlight bindings have been moved to leds, whereas they don't look
similarly.

We have common.txt LED bindings, that all LED class drivers' bindings
have to follow. Neither backlight bindings nor these ones do that,
which introduces some mess.

Eventually adding a sub-directory, e.g. remote_control could make it
somehow logically justified, but still - shouldn't bindings be
placed in the documentation directory related to the subsystem of the
driver they are predestined to?

In principle I agree with you, also because I understood that the
led kind of bindings are for those LEDs which main function is to
emit light.

There is no need for a remote control directory, because there is
one already under bindings/media, where all the remote
controllers are placed.

Now this is a matter of interpretation, is this an IR LED used by
the driver as remote controller or is this a remote controller
with just an IR LED?

In any case, I will wait for you and Rob to agree where is best
to place the binding, then I will send a new version.

Thanks,
Andi

And there are probably LED bindings that don't follow common.txt either.

No. While binding directories often mirror the driver directories, they 
are not the same. Bindings are grouped by types of h/w and IR LEDs are a 
type of LED.

If you prefer a sub-dir, that is fine with me.

Fine. So how about sub-dir "ir" ?

would we put here all the remote control bindings that currently
are under media?

No. Only if they are just an LED that happens to be IR.
