2010-02-26V4L/DVB (13930): dib0700: rework IR logic for firmware 1.20Devin Heitmueller
When firmware 1.20 was introduced, the dib0700 switched from a polling model using a USB control message, to the messages being delivered on a USB bulk pipe. The code I originally added would do a blocking read on the pipe with a 50ms timeout. Because the dvb-usb-remote code makes use of the global workqueue, this resulted in the global workqueue being blocked 50% of the time. Also, the synchronous urb_bulk_msg() call would burn excess CPU time (reflected as an abnormal increase in the system's load average when devices were connected). Rework the logic so that we now setup an asynchronous callback on the bulk pipe, so that we now only handle RC data when it arrives on the pipe. Note that we provide a stub function for the RC polling callback so that we can continue to leverage the shared code in dvb-usb-rc for the setting up of the input device.

2009-12-16V4L/DVB (13586): DiB0700: Add parameter to change the buffer sizeOlivier Grenie
Add parameter to change the buffer size. This buffer size is specified in number of Ts packet. This parameter is stored inside the state. For firmware higher than 1.21, the xfer buffer size can be changed inside the dib0700 usb bridge the firware version is stored inside the state Signed-off-by: Patrick Boettcher <pboettcher@kernellabs.com> Signed-off-by: Olivier Grenie <olivier.grenie@dibcom.fr> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2008-11-16V4L/DVB (9639): Make dib0700 remote control support work with firmware v1.20Devin Heitmueller
The format for reading the IR controller changed in firmware 1.20. It now provides the events on bulk endpoint 1 instead of using a control request. Support the new format, providing backward compatibility for users who might be using older firmware. Thanks to Patrick Boettcher <patrick.boettcher@desy.de> for providing the required information on how the version 1.20 firmware works.

2008-10-12V4L/DVB (9039): Add support for new i2c API provided in firmware version 1.20Devin Heitmueller
The Pinnacle PCTV HD Pro has an xc5000, which exposed a bug in the dib0700's i2c implementation where it did not properly support a single i2c read request (sending it as an i2c write request instead). Version 1.20 of the firmware added support for a new i2c API which supported such requests. This change defaults to fw 1.20 for all devices, but does not default to using the new i2c API (since initial testing suggests problems interacting with the mt2060). Maintainers can enable the use of the new i2c API by putting the following into their frontend initialization: struct dib0700_state *st = adap->dev->priv; st->fw_use_new_i2c_api = 1; Also note that the code expects i2c repeated start to be supported. If the i2c slave does not support repeated start, i2c messsages should have the I2C_M_NOSTART flag set. Thanks to Patrick Boettcher <patrick.boettcher@desy.de> for providing new firmware fixing the issue as well as example i2c code utilizing the interface.

2008-04-24V4L/DVB (7474): support key repeat with dib0700 ir receiverPatrick Boettcher
This patch enables support for repeating last event when a key is holded down with dib0700 devices. It works with rc5 and nec remotes. It also fixes an annoying bug that floods kernel log with "Unknown key" messages after each keypress. This happened because the driver was not resetting infrared register after each poll so it kept polling last key even if nothing was being pressed. Fixing this, (calling rc_setup after each poll), permits to implement key repeat.

2007-10-09V4L/DVB (5964): Fixed remote control for dib0700 with new firmwareJanne Grunau
The new firmware returns the data of the REQUEST_POLL_RC request in reversed order. The default is RC5, but it can be adjusted using a module parameter.
