2008-04-17em28xx: Select reg wait time based on chip IDMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> This is more conservative than just removing the msleep() from em28xx_write_regs_req(), since some old hardware may still need it. So, it will remove the sleep time only for those chips where this removal were tested. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-04-17em28xx-core: speed-up firmware loadMauro Carvalho Chehab
From: Devin Heitmueller <devin.heitmueller@gmail.com> em28xx-core.c: - Remove sleep in i2c message routine which slows down i2c by a factor 10x. Load time for BASE firmware went from 13s to .973s Signed-off-by: Devin Heitmueller <devin.heitmueller@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-04-17em28xx-dvb: Some cleanups and fixesMauro Carvalho Chehab
From: Devin Heitmueller <devin.heitmueller@gmail.com> em28xx-dvb.c: - Remove unneeded xc3028_ctrl structure. The driver automatically preserves the previous value tuner-xc2028.c: - Make the return type for xc2028_get_reg signed, since all of the callers are looking for "< 0" to detect errors.

2008-04-17tuner-xc3028: Avoids too much firmware reloadsMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> xc3028_sleep function is being used with a different meaning. This should be called only before doing S1/S3 sleep. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-04-17em28xx-dvb: Fix analog modeMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> The analog entries are wrong. Fix it. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-04-17em28xx-dvb: don't use videobuf-dvbMauro Carvalho Chehab
From: Aidan Thornton <makosoft@googlemail.com> Modifies em28xx-dvb not to use videobuf-dvb, but instead to include the code for registering dvb devices locally and use the URB management code in the em28xx driver directly. DVB data streaming should now work. Signed-off-by: Aidan Thornton <makosoft@googlemail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-04-17em28xx: generalise URB setup code.Mauro Carvalho Chehab
From: Aidan Thornton <makosoft@googlemail.com> Move the URB setup and management code to em28xx-core.c and generalise it slighlty so that the DVB code can use it. Signed-off-by: Aidan Thornton <makosoft@googlemail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-04-17em28xx-dvb: add support for the HVR-900Mauro Carvalho Chehab

2008-04-17em28xx: Sets frequency when changing to analog modeMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> This will make tuner-xc2028 to change to analog, if needed. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-04-17em28xx-dvb: videobuf callbacks are waiting for em28xx_fhMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> Thanks to Devin Heitmueller <devin.heitmueller@gmail.com> for pointing this issue. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-04-17em28xx: several fixes on gpio programmingMauro Carvalho Chehab
From: Devin Heitmueller <devin.heitmueller@gmail.com> em28xx-cards.c: - Fix reversed val/rst values in both analog_gpio and digital_gpio vectors - Fix crash that would was occurring during every analog startup while looping over gpio_ctl - Remove what appears to be a redundant setting of gpio_ctl->val - Don't use OREN538 demodulation for the HVR-950 (prevents ATSC scanning from working) em28xx-dvb.c: - Tuner should be in digital mode when issuing the reset - Add copyright - Change struct definition (corresponds to fix in em28xx-cards.c for gpio_ctl looping) Signed-off-by: Devin Heitmueller <devin.heitmueller@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-04-17em28xx: share the same xc3028 setup for analog and digital modesMauro Carvalho Chehab

2008-04-17em28xx-dvb: Add support for HVR950Mauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> This patch adds DVB support for Hauppauge HVR950. Thanks to Michael Krufky <mkrufky@linuxtv.org> for getting those values. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-04-17Improve generic support for setting gpio valuesMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> em28xx based devices with xc3028 may require some specific gpio values. This patch adds a generic handling for such values. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-04-17em28xx: Fix KconfigMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> Some devices have msp3400 audio decoder chip. Selects it, if em28xx. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-04-17em28xx: add a module to handle dvbMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> This patch adds em28xx-dvb. This driver is highly based on cx88-dvb and saa7134-dvb. This code currently loads and unloads successfully. However, some changes are needed to properly support the mpeg streams and to setup em28xx to work on DVB mode. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

2008-03-28pvrusb2: Fix slop involving use of struct which might not be definedMike Isely
From: Mike Isely <isely@pobox.com> When the DVB interface is not compiled, the pvr2_dvb_props struct is not available - so it really should be ifdef'ed out as well. This didn't cause an error because in this context its usage was as an opaque pointer. But it really shouldn't be present at all if DVB is not enabled. Signed-off-by: Mike Isely <isely@pobox.com>

2008-03-28pvrusb2: Rework USB streaming start/stop executionMike Isely
From: Mike Isely <isely@pobox.com> The commands to start / stop USB streaming for an analog device are fairly standard, owing to the fact that all supported devices apparently started from the same common reference design. However with digital mode, the commands seem to vary by vendor. This change makes that variance more explicit. It also cleans up a related problem for OnAir devices which prevented digital mode from working at all. Signed-off-by: Mike Isely <isely@pobox.com>
2008-03-28pvrusb2: Centralize handling of simple FX2 commandsMike Isely
From: Mike Isely <isely@pobox.com> Numerous places in the driver need to issue simple commands to the FX2 microcontroller (e.g. only 1 or 2 bytes, no reply needed). Previously each place that did this, had to take lock, set up a central buffer, and call the function to perform the handshake. This change puts these steps into a single spot. This also has the effect of removing the need to mess with the control lock from numerous places in the code. Signed-off-by: Mike Isely <isely@pobox.com>
2008-03-28pvrusb2: Make FX2 command codes unsigned constantsMike Isely

2008-03-28pvrusb2: Implement statistics for USB I/O performance / trackingMike Isely
From: Mike Isely <isely@pobox.com> Implement a mechanism in the pvrusb2 driver for gathering statistics on the stream buffering, including bytes transferred, buffers handled, buffers in flight, etc. This is useful for debugging certain classes of streaming issues and for determining if the buffer pool size is generally correct for the driver.

2008-02-09pvrusb2-dvb: Further clean up dvb init/tear-downMike Isely
From: Mike Isely <isely@pobox.com> Move pvr2_dvb_adapter usage out of the pvrusb2 driver core - it's really private to the pvrusb2-dvb module and nothing outside of the dvb implementation should care about it. Creation / destruction of the pvr2_dvb_adapter instance is now contained entirely within pvrusb2-dvb.c. Signed-off-by: Mike Isely <isely@pobox.com>
2008-02-09pvrusb2-dvb: Don't initialize if device lacks a digital sideMike Isely
From: Mike Isely <isely@pobox.com> In the end we'd like the dvb interface to always be present - even for analog devices (via the mpeg encoder). However right now pvrusb2-dvb won't operate correctly if the hardware doesn't have a digital tuner, so don't initialize the DVB interface unless we know we have a digital tuner. Signed-off-by: Mike Isely <isely@pobox.com>
2008-02-09pvrusb2-dvb: Remove digital_up flagMike Isely
From: Mike Isely <isely@pobox.com> Other pvrusb2-dvb changes have made the digital_up flag obsolete. So kill it. Signed-off-by: Mike Isely <isely@pobox.com>
2008-02-09pvrusb2-dvb: Rework module tear-downMike Isely
From: Mike Isely <isely@pobox.com> Rather than making an explicit call to tear down the pvrusb2-dvb module, use the callback in the pvr2_channel structure. This has the advantage that now tear-down only happens when it makes sense. The previous implementation had scenarios where it was possible for the tear-down call to happen without a prior initialization. Signed-off-by: Mike Isely <isely@pobox.com>
2008-02-06pvrusb2: Clean up dvb streaming start/stopMike Isely
From: Mike Isely <isely@pobox.com> Eliminate the need for a separate pvr2_dvb_fh; since in the DVB context there can only ever be a single instance then there is no need for a separate instance to handle streaming state. This simplifies the module. Also move streaming start/stop out of the feed thread and into the driver's main context - which makes it possible for streaming start up failures to be detected by the DVB core. Signed-off-by: Mike Isely <isely@pobox.com>
2008-02-05pvrusb2: Fix oops in pvrusb2-dvbMike Isely
From: Mike Isely <isely@pobox.com> The pvrusb2-dvb feed thread cannot be allowed to exit by itself without first waiting for kthread_should_stop() to return true. Otherwise the driver will have a dangling task_struct context, which will cause a very nasty kernel oops. Signed-off-by: Mike Isely <isely@pobox.com>

2008-02-03pvrusb2: add DVB API frameworkMike Isely
From: Michael Krufky <mkrufky@linuxtv.org> Add basic framework for the DVB API. This is enough to control the tuner & demod of the digital frontend, but the stream & buffer handling is still missing. Additional note from Mike Isely <isely@pobox.com> - also, since these changes are still very experimental arrange for DVB changes to be compiled in via new CONFIG_VIDEO_PVRUSB2_DVB option, for now.
