As done first in lgdt330x.c, calculate signal strength from SNR up to 35dB Even though the SNR can go higher than 35dB, there is some comfort factor in having a range of strong signals that can show at 100% Signed-off-by:

In the original code, probe_out could be reached when res was null and then when the irq had not yet been requested. In those cases, the call to free_irq is not needed, so move probe_out down and introduce a new label for the case where calling free_irq is useful. The semantic match that finds this problem is as follows: // <smpl> @r@ expression E, E1; identifier f; statement S1,S2,S3; @@ if (E == NULL) { ... when != if (E == NULL || ...) S1 else S2 when != E = E1 *E->f ... when any return ...; } else S3 // </smpl> Signed-off-by:Julia Lawall <julia@diku.dk> Signed-off-by:

The ADV7170/ADV7171 can operate in either 8-bit or 16-bit YCrCb Mode. * 8-Bit YCrCb Mode This default mode accepts multiplexed YCrCb inputs through the P7-P0 pixel inputs. The inputs follow the sequence Cb0, Y0 Cr0, Y1 Cb1, Y2, etc. The Y, Cb and Cr data are input on a rising clock edge. * 16-Bit YCrCb Mode This mode accepts Y inputs through the P7–P0 pixel inputs and multiplexed CrCb inputs through the P15–P8 pixel inputs. The data is loaded on every second rising edge of CLOCK. The inputs follow the sequence Cb0, Y0 Cr0, Y1 Cb1, Y2, etc. Signed-off-by:

The RGB mode does not work correctly. It captures fine at 640x480 but whenever the scaling engine is used to produce another resolution, color corruption occurs (lots of erroneous pink and green). It is not clear how the scaling engine is supposed to work and how it knows which pixel format it is dealing with. Work around this problem by disabling RGB support. YUYV scaling works just fine. Test case: gst-launch v4l2src ! video/x-raw-rgb,bpp=16,width=320,height=240 ! \ ffmpegcolorspace ! xvimagesink Signed-off-by:

There is no limit to the number of displays that can registered with DSS2. The current value of MAX_DISPLAYS is 3, set this to 10 so that the 'displays' member of omap2video_device struct can store more omap_dss_device pointers. This fixes a crash seen in omap_vout_probe when DSS2 registers for more than 3 displays. Signed-off-by:

Add support for DSI panels. DSI video mode panels will work directly. For command mode panels, we will need to trigger updates regularly. This isn't done by the omap_vout driver currently. It can still be supported if we connect a framebuffer device to the panel and configure it in auto update mode. Signed-off-by:

Currently, in omap_vout_isr(), if the panel type is DPI, and if we get either VSYNC or VSYNC2 interrupts, we proceed ahead to set the current buffers state to VIDEOBUF_DONE and prepare to display the next frame in the queue. On OMAP4, because we have 2 LCD managers, the panel type itself is not sufficient to tell if we have received the correct irq, i.e, we shouldn't proceed ahead if we get a VSYNC interrupt for LCD2 manager, or a VSYNC2 interrupt for LCD manager. Fix this by correlating LCD manager to VSYNC interrupt and LCD2 manager to VSYNC2 interrupt. Signed-off-by:

Currently, there is a lot of redundant code is between DPI and VENC panels, this can be made common by moving out field/interlace specific code to a separate function called omapvid_handle_interlace_display(). There is no functional change made. Signed-off-by:

The commit 383e4f69 makes reqbuf prevent requesting a larger size buffer than what is allocated at kernel boot during omap_vout_probe. In omap_vout_buffer_setup callback API, the requested size is compared with vout->buffer_size, this isn't correct as vout->buffer_size is later set to the size requested in reqbuf. When the video device is opened the next time, this check will prevent us to allocate a buffer which is larger than what we requested the last time. Don't use vout->buffer_size, always check with the parameters video1_bufsize or video2_bufsize. Signed-off-by:

If "i" is 2 then when we call cx25821_video_mux() we'd end up going past the end of the cx25821_boards[dev->board]->input[]. The INPUT() macro obfuscates what's going on in that function so it's a bit hard to follow. And as Mauro points out the hard coded 2 is not very helpful. Signed-off-by:

The Kconfig symbol RADIO_TEA5764_XTAL is unused. The code does use a RADIO_TEA5764_XTAL macro, but does that rather peculiar. But there seems to be a way to keep both. (The easiest way out would be to rip out both the Kconfig symbol and the macro.) Note there's also a module parameter 'use_xtal' to influence all this. Signed-off-by:

The macros that define the minimum/maximum input and output sizes are defined in seperate files and have no consistent naming.
