Currently, the logic to load ir i2c ancillary module is broken. It is associated to Hauppauge devices with IR flag on their eeprom, no matter if the device uses i2c or em28xx direct IR support. That's wrong. Instead, add a flag to the boards that use i2c IR chips and load the module only for those devices and if ir is not disabled. Signed-off-by:Mauro Carvalho Chehab <mchehab@redhat.com>

ir-kbd-i2c's ir_probe() function can be called much later (i.e. at ir-kbd-i2c module load), than the lifetime of a struct IR_i2c_init_data allocated off of the stack in cx18_i2c_new_ir() at registration time. Make sure we pass a pointer to a persistent IR_i2c_init_data object at i2c registration time. Thanks to Brian Rogers, Dustin Mitchell, Andy Walls and Jean Delvare to rise this question. Before this patch, if ir-kbd-i2c were probed after SAA7134, trash data were used. Compile tested only, but the patch is identical to em28xx one. So, it should work properly. Signed-off-by: -

Various frontend driver have parameter checks in their set_frontend functions and return an error if the parameters are not supported, tda10021 and cx24116 to name two. The tuning ioctls FE_SET_FRONTEND/FE_SET_PROPERTY only change values in the property cache and return before set_frontend is called. If a set_frontend call in software zigzag algorithm fails and the card was previously locked it will report a lock and the new parameters but is still tuned to the old transport. This is not detectable from userspace. This change checks the return values of fe->ops.set_frontend and changes the state to the added FESTATE_ERROR for software zigzag. No lock will be reported to userspace if the State is FESTATE_ERROR. Signed-off-by:

Now that we've figured out the higher compression settings (supported in libv4l-0.6.0 and later, so after this patch the driver should be used with libv4l-0.6.0 or higher only!), we can enable higher framerates. Which means lower exposure times, which is important for the use of the pac207 in full daylight. This patch also tweakes the brightness default and the per color gain balances to use the values which are adviced by Pixart in the pac207 application note. Signed-off-by:

Depending on the model there are three different firmwares to choose from. Unfortunately if a cx23885 is loaded first, then the global firmware name is overwritten with that firmware and if ivtv is loaded next, then it tries to load the wrong firmware. In addition, the original approach would also overwrite any firmware that the user specified explicitly. Cc: Jarod Wilson <jarod@wilsonet.com> Signed-off-by:

The input subsystem checks if get_keycode works for a scan code. Due to that, we need to return a valid value when there's some space at the table that can be used by a scancode. Signed-off-by: -

Implements handler for EVIOCGKEYCODE/EVIOCSKEYCODE via adding two new callbacks to the input device. Since on dvb-usb a scan code has 16 bits, to fulfill rc5 standard codes, the default getkeycode/setkeycode input methods would require the driver to spend up to 64 Kb of a sparse table. Instead, add two new callbacks to the event device. With this, it is now possible to replace the keycode tables. There are, however, a few implementation details at the current patch: 1) It will replace the existing device keytable, instead of creating an instance of the data. This works. However, if two devices pointing to the same table were connected, changing the IR table of one will also change the IR table for the other (the solution for this one is simple: just kmalloc some memory); 2) In order to change the scan code, you need first to change the key to KEY_RESERVED or KEY_UNKNOWN to free some space at the table (solution: allocate some additional space for newer scan codes or allow dynamic table grow); 3) The table size cannot be extended. It would be easy to allow the table to grow dynamically: just calling kmalloc(size+1); kfree(old). Yet, maybe we can just create a bigger table with a fixed size, like for example a table with 128 entries. This should be enough even for a very big IR. The current issues should be addressed on a later patch. Signed-off-by: -

In order to be closer to V4L IR implementation, it is needed to replace u8 custom, data to: u16 scan This allows using non-rc5 mappings, like the 8 bit keycodes used on older protocols. It will also allow future implementations of rc6 keystrokes when needed. Signed-off-by: -

Currently, V4L uses a scancode table whose index is the scancode and the value is the keycode. While this works, it has some drawbacks: 1) It requires that the scancode to be at the range 00-7f; 2) keycodes should be masked on 7 bits in order for it to work; 3) due to the 7 bits approach, sometimes it is not possible to replace the default keyboard to another one with a different encoding rule; 4) it is different than what is done with dvb-usb approach; 5) it requires a typedef for it to work. This is not a recommended Linux CodingStyle. This patch is part of a larger series of IR changes. It basically replaces the IR_KEYTAB_TYPE tables by a structured table: struct ir_scancode { u16 scancode; u32 keycode; }; This is very close to what dvb does. So, a further integration with DVB code will be easy. While we've changed the tables, for now, the IR keycode handling is still based on the old approach. The only notable effect is the redution of about 35% of the ir-common module size: text data bss dec hex filename 6721 29208 4 35933 8c5d old/ir-common.ko 5756 18040 4 23800 5cf8 new/ir-common.ko In thesis, we could be using above u8 for scancode, reducing even more the size of the module, but defining it as u16 is more convenient, since, on dvb, each scancode has up to 16 bits, and we currently have a few troubles with rc5, as their scancodes are defined with more than 8 bits. This patch itself shouldn't be doing any functional changes. Signed-off-by: -
