Huh? Lircd is not needed for the IR to work. All it needs is to fix the RC remote keycode table.
Once fixed, every time someone would use the board, the IR will work.
Michel,
By default, the driver will use an empty table, unless something else is specified at saa7134-input.c.
All you need to do is to add an extra case to saa7134_probe_i2c_ir, specifying your IR keytable.
Something like:
void saa7134_probe_i2c_ir(struct saa7134_dev *dev)
{
...
case SAA7134_BOARD_TEVION_DVBT_220RF:
dev->init_data.name = "Tevion/Kworld/Conceptronic DVB-T 220RF";
dev->init_data.ir_codes = RC_MAP_KWORLD_PLUS_TV_ANALOG;
info.addr = 0x30;
break;
The actual name of the keymap (RC_MAP_KWORLD_PLUS_TV_ANALOG) may need to be changed. Take a look at
drivers/media/rc/keymaps/ for the existing keymaps. Maybe your IR is like this one:
drivers/media/rc/keymaps/rc-kworld-plus-tv-analog.c
You basically need to type each key on your remote, and check for the message,
comparing the scancode with the key name. If none of the existing maps match, just copy one
file with another name, edit it, and add your entries. Don't forget to add it to drivers/media/rc/keymaps/Makefile.
After having it fixed, please send us the patch, for its addition upstream.
Thanks,
Mauro
