From 0204fe2a20da12ddae1b564712ceeebc55214f97 Mon Sep 17 00:00:00 2001 From: Jarod Wilson Date: Tue, 1 Jun 2010 17:30:35 -0300 Subject: V4L/DVB: IR: add RC6 keymap for Windows Media Center Ed. remotes This is the RC6 keymap for the Windows Media Center Edition remotes that come bundled with MCE/eHome Infrared Remote transceivers. Tested with 3 different variants of the remote, but its possible there are still some additional keys missing, but its simple enough to add them in later... This patch also adds an IR_TYPE_ALL convenience macro to make life easier for receivers that support all IR protocols. v2: fix an erroneous comment that referred to imon devices Signed-off-by: Jarod Wilson Signed-off-by: Mauro Carvalho Chehab --- include/media/rc-map.h | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'include') diff --git a/include/media/rc-map.h b/include/media/rc-map.h index c78e99a435b6..36ee280d42a9 100644 --- a/include/media/rc-map.h +++ b/include/media/rc-map.h @@ -19,6 +19,9 @@ #define IR_TYPE_SONY (1 << 4) /* Sony12/15/20 protocol */ #define IR_TYPE_OTHER (1u << 31) +#define IR_TYPE_ALL (IR_TYPE_RC5 | IR_TYPE_NEC | IR_TYPE_RC6 | \ + IR_TYPE_JVC | IR_TYPE_SONY | IR_TYPE_OTHER) + struct ir_scancode { u32 scancode; u32 keycode; @@ -107,6 +110,7 @@ void rc_map_init(void); #define RC_MAP_PV951 "rc-pv951" #define RC_MAP_RC5_HAUPPAUGE_NEW "rc-rc5-hauppauge-new" #define RC_MAP_RC5_TV "rc-rc5-tv" +#define RC_MAP_RC6_MCE "rc-rc6-mce" #define RC_MAP_REAL_AUDIO_220_32_KEYS "rc-real-audio-220-32-keys" #define RC_MAP_TBS_NEC "rc-tbs-nec" #define RC_MAP_TERRATEC_CINERGY_XS "rc-terratec-cinergy-xs" -- cgit v1.2.3 From 0dc50942d6f23989ffb3024aa2271941ec44aea8 Mon Sep 17 00:00:00 2001 From: David Härdeman Date: Mon, 7 Jun 2010 16:32:33 -0300 Subject: V4L/DVB: ir-core: partially convert ir-kbd-i2c.c to not use ir-functions.c MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Partially convert drivers/media/video/ir-kbd-i2c.c to not use ir-functions.c Signed-off-by: David Härdeman Signed-off-by: Mauro Carvalho Chehab --- drivers/media/video/ir-kbd-i2c.c | 14 ++++---------- include/media/ir-kbd-i2c.h | 2 +- 2 files changed, 5 insertions(+), 11 deletions(-) (limited to 'include') diff --git a/drivers/media/video/ir-kbd-i2c.c b/drivers/media/video/ir-kbd-i2c.c index 29d439742653..27ae8bbfb477 100644 --- a/drivers/media/video/ir-kbd-i2c.c +++ b/drivers/media/video/ir-kbd-i2c.c @@ -47,7 +47,7 @@ #include #include -#include +#include #include /* ----------------------------------------------------------------------- */ @@ -272,11 +272,8 @@ static void ir_key_poll(struct IR_i2c *ir) return; } - if (0 == rc) { - ir_input_nokey(ir->input, &ir->ir); - } else { - ir_input_keydown(ir->input, &ir->ir, ir_key); - } + if (rc) + ir_keydown(ir->input, ir_key, 0); } static void ir_work(struct work_struct *work) @@ -439,10 +436,7 @@ static int ir_probe(struct i2c_client *client, const struct i2c_device_id *id) dev_name(&client->dev)); /* init + register input device */ - err = ir_input_init(input_dev, &ir->ir, ir_type); - if (err < 0) - goto err_out_free; - + ir->ir_type = ir_type; input_dev->id.bustype = BUS_I2C; input_dev->name = ir->name; input_dev->phys = ir->phys; diff --git a/include/media/ir-kbd-i2c.h b/include/media/ir-kbd-i2c.h index 0506e45c9a4f..5e96d7a430be 100644 --- a/include/media/ir-kbd-i2c.h +++ b/include/media/ir-kbd-i2c.h @@ -11,7 +11,7 @@ struct IR_i2c { struct i2c_client *c; struct input_dev *input; struct ir_input_state ir; - + u64 ir_type; /* Used to avoid fast repeating */ unsigned char old; -- cgit v1.2.3 From 9b7c54d926284c5277cff3ef3cfe29f26568306a Mon Sep 17 00:00:00 2001 From: Jarod Wilson Date: Wed, 16 Jun 2010 17:55:25 -0300 Subject: V4L/DVB: IR: add tx callbacks to ir-core Signed-off-by: Jarod Wilson Signed-off-by: Mauro Carvalho Chehab --- include/media/ir-core.h | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-) (limited to 'include') diff --git a/include/media/ir-core.h b/include/media/ir-core.h index ad1303f20e00..9b957af21588 100644 --- a/include/media/ir-core.h +++ b/include/media/ir-core.h @@ -47,15 +47,21 @@ enum rc_driver_type { * is opened. * @close: callback to allow drivers to disable polling/irq when IR input device * is opened. + * @s_tx_mask: set transmitter mask (for devices with multiple tx outputs) + * @s_tx_carrier: set transmit carrier frequency + * @tx_ir: transmit IR */ struct ir_dev_props { enum rc_driver_type driver_type; unsigned long allowed_protos; u32 scanmask; - void *priv; + void *priv; int (*change_protocol)(void *priv, u64 ir_type); int (*open)(void *priv); void (*close)(void *priv); + int (*s_tx_mask)(void *priv, u32 mask); + int (*s_tx_carrier)(void *priv, u32 carrier); + int (*tx_ir)(void *priv, const char *buf, u32 n); }; struct ir_input_dev { -- cgit v1.2.3 From f6a20eb1a2d35660240cd1eb8dc2bd6504a0c6c5 Mon Sep 17 00:00:00 2001 From: Klaus Schmidinger Date: Thu, 1 Jul 2010 01:37:34 -0300 Subject: V4L/DVB: Add FE_CAN_TURBO_FEC Some (North American) providers use a non-standard mode called "8psk turbo fec".

01:07:53 -0300 Subject: V4L/DVB: IR: add ir-core to lirc userspace decoder bridge driver v2: copy of buffer data from userspace done inside this plugin/driver, keeping the actual drivers minimal, and more flexible in what we can deliver to them later on (they may be fed from within kernelspace later on, by an in-kernel IR encoder).

The videobuf_sg_dma_map/unmap then become unused and can be removed.

Move all those definitions to linux/usb/video.h where they can be shared by the two drivers (and be available for userspace applications).

dib0700: break keytable into NEC and RC-5 variants Instead of having one big keytable with 2 protocols inside, break it into two separate tables, being one for NEC and another for RC-5 variants, and properly identify what variant should be used at the boards entries.
