c84251bb12 [media] cx24120: Rework vco function to remove xxyyzz variable
Change calculate_vco function to send_vco to tidy up cx24120_init
function.
xxyyzz variable is remnants of a manual div & remainder codepath
to perform a u64 rounded div; replace with kernel macro
DIV_ROUND_CLOSEST_ULL
Hex values provided to the message are mainly variables calculated
within this function, replace with these to remove hardcoding.

270e70713b [media] cx24120: Add missing command to cx24120_check_cmd
This patch adds in a missing command to cx24120_check_cmd. This part
of the old reverse engineered driver was quite hard to follow - it's
presumed the compiler did some neat optimisation that wasn't easy to
decode. This command was checked for in that version but not copied
across to the new switch statement.

For reference, old reverse engineered code:
xxzz = cmd->id - 0x11;			// look for specific message id
if ( xxzz <= 0x13 ) {
	msg_cmd_mask = 1 << xxzz;
	//0x0F8021 // if cmd_id 17 or 22 or 33-36, 42, 47, 57-61 etc. disable mpeg output
	if ( msg_cmd_mask & 0x0F8021 ) {	// 000011111000000000100001b
		cx24120_msg_mpeg_output_global_config(state, 0);
		msleep(100);
		state->dvb_s2_mode &=  0xFD;	// reset mpeg out enable flag
	}
}

5afc9a25be [media] Add support for TechniSat Skystar S2
This patch adds support for the Technisat Skystar S2 - this
has been tried before but the cx24120 driver was a bit out of shape
and it didn't got any further:

https://patchwork.linuxtv.org/patch/10575/

It is an old card, but currently being sold off for next to nothing,
so it's proving quite popular of late. Noticing it's quite similar
to the cx24116 and cx24117 I've rewritten the driver in a similar way.

There were a few registers and commands from those drivers
missing from this one I've tested out and found they do something so
they've been added in to speed up tuning and to make get_frontend
return something useful.

For every frontend entry, we need to add the adapter's size. There
are already two patches fixing it. So, it doesn't seem trivial to
keep it there at the right place.

Also, currently, the indentation is wrong on all places.

So, it seems that keeping it right is not too trivial.

Better to use a macro that would do it for us, at least while
this is not converted to dvb-usb-v2.

Add support in rc-core for drivers which implement the wakeup scancode
filter by encoding the scancode using the raw IR encoders. This is by
way of rc_dev::encode_wakeup which should be set to true to make the
allowed wakeup protocols the same as the set of raw IR encoders.

As well as updating the sysfs interface to know which wakeup protocols
are allowed for encode_wakeup drivers, also ensure that the IR
decoders/encoders are loaded when an encode_wakeup driver is registered.

a0466f15b4 [media] rc: ir-rc5-decoder: Add encode capability
Add the capability to encode RC-5, RC-5X and RC-5-SZ scancodes as raw
events. The protocol is chosen based on the specified protocol mask,
and whether all the required bits are set in the scancode mask, and
none of the unused bits are set in the scancode data. For example a
scancode filter with bit 16 set in both data and mask is unambiguously
RC-5X.

The Manchester modulation helper is used, and for RC-5X it is used twice
with two sets of timings, the first with a short trailer space for the
space in the middle, and the second with no leader so that it can
continue the space.

The encoding in RC-5-SZ first inserts a pulse and then simply utilizes
the generic Manchester encoder available in rc-core.
