2008-02-06pvrusb2: Allow digital streaming without encoder firmwareMike Isely
From: Mike Isely <isely@pobox.com> The encoder is not a part of the pipeline when in digital mode, so streaming is OK in this case even when the encoder's firmware is not loaded. Modify the driver core handling of this scenario to permit streaming. Signed-off-by: Mike Isely <isely@pobox.com>

2008-02-03pvrusb2: Enhance core logic to also control digital streamingMike Isely
From: Mike Isely <isely@pobox.com> This is a major pvrusb2 change. The driver core has an algorithm that is used to cleanly sequence the changes needed to enable / disable video streaming. The algorithm had originally been written for analog streaming, but when in digital mode the pipeline is considerably different - for example the mpeg encoder is not used. These changes to the core logic implement correct pipeline control when in digital mode. Knowing which pipeline to handle and how to handle it is completely driven by the current input selection. So, in theory, to perform digital stream now all one has to do is switch input to dtv and start streaming as usual. Well, in theory. The reality is that digital tuner and demod control are still not in the driver core yet so until that is present there's nothing to actually stream. Signed-off-by: Mike Isely <isely@pobox.com>
2008-02-03pvrusb2: Define digital control scheme device attributesMike Isely
From: Mike Isely <isely@pobox.com> Unlike analog control, control of the digital side is not nearly as uniform among different devices. So we have to specify the correct digital control scheme as a new device attribute. Signed-off-by: Mike Isely <isely@pobox.com>

2008-02-03pvrusb2: Ensure that default input selection is actually validMike Isely
From: Mike Isely <isely@pobox.com> Previously the pvrusb2 driver just started with the default input to be "television". But if the device doesn't support an analog tuner then this default must be different. New logic here selects a reasonable default based on the actual valid set of available inputs. Signed-off-by: Mike Isely <isely@pobox.com>
2008-02-03pvrusb2: Improve control validation for enumerationsMike Isely
From: Mike Isely <isely@pobox.com> When an enumeration control is changed, the pvrusb2 driver assumed that the enumeration values were continuous. That is no longer true; this change allows for properly input validation even when not all enumeration values are legal (which can happen with input selection based on what the hardware supports).

2008-02-03pvrusb2: v4l2 implementation fixes for input selectionMike Isely
From: Mike Isely <isely@pobox.com> Now that the pvrusb2 driver can dynamically choose which inputs to make available depending on the hardware, the enumeration of input choices is no longer a contiguous range of integers. Unfortunately this causes a problem in the v4l2 implementation since the input enumeration requires continuity in the API. This change implements a mapping in order to preserve the v4l2 interface requirement. Signed-off-by: Mike Isely <isely@pobox.com>

2008-02-03pvrusb2: Account for dtv choice (a bit) in v4l2 implementationMike Isely
From: Mike Isely <isely@pobox.com> The v4l2 implementation in pvru2b2 must produce a sane answer when asked, when the input choice is set to dtv. Signed-off-by: Mike Isely <isely@pobox.com>
2008-02-03pvrusb2: Dynamically control range of input selectionsMike Isely
From: Mike Isely <isely@pobox.com> This follows from defining the available inputs as device attributes. This change causes the driver to adjust its list of inputs based on those attributes. Now, for example, the FM radio will appear as a choice only if the hardware supports an FM radio. Signed-off-by: Mike Isely <isely@pobox.com>
2008-02-03pvrusb2: Define device attributes for all input modesMike Isely
From: Mike Isely <isely@pobox.com> Different devices support different input types. Up until now we've really been assuming that everyone has an analog tuner, an FM radio, composite, and s-video inputs. But as we add other devices, these assumptions are no longer true. The way to deal with this is to define the available inputs as additional device attributes, so that the driver can adjust its internal behavior accordingly.

2008-02-26 em28xx: Correct use of ! and &Mauro Carvalho Chehab
From: Julia Lawall <julia@diku.dk> In commit e6bafba5b4765a5a252f1b8d31cbf6d2459da337, a bug was fixed that involved converting !x & y to !(x & y). The code below shows the same pattern, and thus should perhaps be fixed in the same way. This is not tested and clearly changes the semantics, so it is only something to consider. The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ expression E1,E2; @@ ( !E1 & !E2 | - !E1 & E2 + !(E1 & E2) ) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

2008-02-05Add support for xc3028-based boardsMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> This patch adds support for the following saa7134 xc3028 based boards: 132 -> AVerMedia Cardbus TV/Radio (E506R) [1461:f436] 133 -> AVerMedia Hybrid TV/Radio (A16D) [1461:f936] 134 -> Avermedia M115 [1461:a836] 135 -> Compro VideoMate T750 [185b:c900] This is based on a original patch thanks to Markus Rechberger that added xc3028 gpio init code for the above boards. This patch moves saa7134_tuner_callback to saa7134-cards, originally used only by tda8290 DVB-S boards. The callback was made more generic to support other tuners. Currently, it supports both tda8290 and xc2028/xc3028 tuners. Added also the basis for xc5000 tuner callback.
