I have also compiled yours and Henry's work into a patch that applies cleanly to the latest build of v4l source (eedd95da0715). Hope this is of some help. Thanks. /*********************************************************************/ --- a/linux/drivers/media/common/ir-keymaps.c 2007-06-28 10:30:22.000000000 -0400 +++ b/linux/drivers/media/common/ir-keymaps.c 2007-06-29 08:53:51.000000000 -0400 @@ -1503,6 +1503,60 @@ EXPORT_SYMBOL_GPL(ir_codes_hauppauge_new); +IR_KEYTAB_TYPE ir_codes_kworld_atsc110[IR_KEYTAB_SIZE] = { + [ 0x0 ] = KEY_1, + [ 0x1 ] = KEY_2, + [ 0x2 ] = KEY_3, + [ 0x3 ] = KEY_4, + [ 0x4 ] = KEY_5, + [ 0x5 ] = KEY_6, + [ 0x6 ] = KEY_7, + [ 0x7 ] = KEY_8, + [ 0x8 ] = KEY_9, + [ 0xa ] = KEY_0, + [ 0x9 ] = KEY_ESC, /* UP ARROW */ + [ 0xc ] = KEY_POWER, /* POWER */ + [ 0x0a ] = KEY_MUTE, /* MUTE */ + [ 0x0b ] = KEY_SEARCH, /* SEARCH */ + [ 0x0d ] = KEY_EPG, /* GUIDE */ + [ 0x1b ] = KEY_RECORD, /* RECORD */ + [ 0x16 ] = KEY_PAUSE, /* PAUSE */ + [ 0x1a ] = KEY_STOP, /* STOP */ + [ 0x1d ] = KEY_VOLUMEDOWN, /* VOLUME- */ + [ 0x1c ] = KEY_VOLUMEUP, /* VOLUME+ */ + [ 0x1f ] = KEY_CHANNELDOWN, /* CHANNEL/PAGE- */ + [ 0x1e ] = KEY_CHANNELUP, /* CHANNEL/PAGE+ */ + [ 0x10 ] = KEY_UP, /* KEY_SCROLLUP */ + [ 0x12 ] = KEY_LEFT, /* KEY_BACK */ + [ 0xe ] = KEY_ENTER, /* KEY_ENTER */ + [ 0x13 ] = KEY_RIGHT, /* KEY_FORWARD */ + [ 0x11 ] = KEY_DOWN, /* KEY_SCROLLDOWN */ + [ 0x14 ] = KEY_MUTE, /* MUTE */ + [ 0x15 ] = KEY_AUDIO, /* STEREO */ + [ 0x16 ] = KEY_VIDEO, /* SOURCE */ + [ 0x17 ] = KEY_ZOOM, /* ZOOM */ + [ 0x18 ] = KEY_PRINT, /* SHUTDOWN */ + [ 0X19 ] = KEY_T, /* TIMESHIFT */ + [ 0x44 ] = KEY_PLAYPAUSE, /* PAUSE/PLAY */ + [ 0x45 ] = KEY_STOP, /* STOP */ + [ 0x40 ] = KEY_REWIND, /* REWIND */ + [ 0x41 ] = KEY_FORWARD, /* FASTFORWARD */ + [ 0x42 ] = KEY_PREVIOUSSONG, /* PREVIOUS */ + [ 0x43 ] = KEY_NEXTSONG, /* NEXT */ + + // buttons a-h + [ 0x48 ] = KEY_A, + [ 0x49 ] = KEY_B, + [ 0x4a ] = KEY_C, + [ 0x4b ] = KEY_D, + [ 0x4c ] = KEY_E, + [ 0x4d ] = KEY_F, + [ 0x4e ] = KEY_G, + [ 0x4f ] = KEY_H +}; + +EXPORT_SYMBOL_GPL(ir_codes_kworld_atsc110); + IR_KEYTAB_TYPE ir_codes_npgtech[IR_KEYTAB_SIZE] = { [ 0x1d ] = KEY_SWITCHVIDEOMODE, /* switch inputs */ [ 0x2a ] = KEY_FRONT, --- a/linux/drivers/media/video/ir-kbd-i2c.c 2007-06-28 10:30:22.000000000 -0400 +++ b/linux/drivers/media/video/ir-kbd-i2c.c 2007-06-29 09:05:56.000000000 -0400 @@ -60,8 +60,11 @@ #define dprintk(level, fmt, arg...) if (debug >= level) \ printk(KERN_DEBUG DEVNAME ": " fmt , ## arg) +static int polling_interval = 100; /* ms */ + /* ----------------------------------------------------------------------- */ +static int kworldatsc110 = 0; /* Both KNC1 and the Kworld ATSC110 cards use the same i2c address */ static int get_key_haup_common(struct IR_i2c *ir, u32 *ir_key, u32 *ir_raw, int size, int offset) { @@ -155,11 +158,14 @@ /* it seems that 0xFE indicates that a button is still hold down, while 0xff indicates that no button is hold - down. 0xfe sequences are sometimes interrupted by 0xFF */ + down. 0xfe and 0x80 sequences are sometimes interrupted by 0xFF */ dprintk(2,"key %02x\n", b); - if (b == 0xff) + /* KNC1 card = 0xfe */ + /* Kworld ATSC110 card = 0x80 */ + + if ((b == 0xfe)||(b & 0x80)) return 0; if (b == 0xfe) @@ -293,7 +299,7 @@ #endif ir_key_poll(ir); - mod_timer(&ir->timer, jiffies + msecs_to_jiffies(100)); + mod_timer(&ir->timer, jiffies + polling_interval*HZ/1000); } /* ----------------------------------------------------------------------- */ @@ -376,10 +382,17 @@ } break; case 0x30: - name = "KNC One"; + if (adap->id == I2C_HW_SAA7134) /* Handled by saa7134-input */ + polling_interval = 50; /* ms */ ir->get_key = get_key_knc1; ir_type = IR_TYPE_OTHER; - ir_codes = ir_codes_empty; + if (kworldatsc110 == 1) { + name = "Kworld ATSC110"; + ir_codes = ir_codes_kworld_atsc110; + } else { + name = "KNC One"; + ir_codes = ir_codes_empty; + } break; case 0x7a: case 0x47: @@ -494,7 +507,7 @@ */ static const int probe_bttv[] = { 0x1a, 0x18, 0x4b, 0x64, 0x30, -1}; - static const int probe_saa7134[] = { 0x7a, 0x47, 0x71, -1 }; + static const int probe_saa7134[] = { 0x7a, 0x30, 0x47, 0x71, -1 }; static const int probe_em28XX[] = { 0x30, 0x47, -1 }; static const int probe_cx88[] = { 0x18, 0x71, -1 }; const int *probe = NULL; @@ -527,6 +540,30 @@ for (i = 0; -1 != probe[i]; i++) { c.addr = probe[i]; rc = i2c_master_recv(&c,&buf,0); + + /* Special case for Kworld ATSC110 remote */ + if (c.adapter->id == I2C_HW_SAA7134 && probe[i] == 0x30) + { + struct i2c_client c2; + + memset (&c2, 0, sizeof(c2)); + c2.adapter = c.adapter; + + for (c2.addr=127; c2.addr > 0; c2.addr--) { + if (0 == i2c_master_recv(&c2,&buf,0)) { + dprintk(1,"Found another device, at addr 0x%02x\n", c2.addr); + break; + } + } + + /* Now do the probe.
