cx18: Improve handling of outgoing mailboxes detected to be busy. When encountering a busy mailbox, sleep instead of polling, and wait for interrupt or timeout. If the mailbox is still busy, force it free. When sending commands, make sure we never create a situation where we mark the mailbox busy upon sending, and ensure we always have a method to cleanly recover from a busy mailbox. Signed-off-by:

Add mutexes to ensure exclusive access for outgoing driver to CX23418 mailboxes. Also wait on a waitq for mailbox acknowledgement from the CX23418 instead of polling. Signed-off-by:

cx18: Use default kernel work queue; fix streaming flag for work handler. Eliminate cx18 specific work queue and use the kernel default work queue. Fixed the F_STREAMING_FLAG for the TS stream so cx18_dvb_work_handler() can know when it is not safe to send MDLs to the firmware. Signed-off-by:

cx18: Reduce number of mmio read retries to improve performance. Experiments have shown 2 things: read retries never improve the result of a suspect mmio read from the CX23418 (the result stays all 0xff's), and that most of the suspected read failures are actually proper reads of values that should be all 0xff's. This change reduces the number of read retries and keeps the count separate from write retries. Signed-off-by:

Note: * At High Symbol Rates we do not have enouph machine cycles to handle the incoming symbols and hence might run into problems at the very end of the specified definition * Most of the equations have been calculated for a master clock of 99 MHz, running at 90MHz, raises lot of issues such as the need to recalculate all of them , which is eventually very painful.

Several chips may be turned off when the device is not used, like audio, video and dvb demods. This patch adds a gpio callback at the core structs to allow turning off such devices. Signed-off-by: -

A previous changeset moved gpio from em28xx struct into em28xx_board. However, the driver were not updated to properly honor those gpio's. Signed-off-by: -

Before this patch, several devices without tuner were kept the value 0 for tuner_type. However, this means TUNER_TEMIC_PAL. Replace those entries for the proper TUNER_ABSENT value. Signed-off-by: -

Instead of a large, ugly switch specifying the gpio tables for each device, let's move it into the boards struct. This also helps to see what boards have already the gpio's for DVB. Signed-off-by: -

Replaces all occurrences of em28xx_write_regs_req() and em28xx_write_reg() used to setup register names by em28xx_write_reg(). Also, documents the register names that are known. This patch were generated by this small perl script: my %reg_map = ( # Register table - the same as defined on parse_em28xx.pl script ); while (<>) { if (m/(.*)em28xx_write_regs_req\(dev\,\s*0x00\,\s*(.*)\,\s*\"\\x(..)\",\s*1\)\;(.*)/) { my $reg = $2; my $val = $3; $val =~ tr/A-f/a-f/; $reg = $reg_map{$reg} if defined($reg_map{$reg}); printf "$1em28xx_write_reg(dev, %s, 0x%s);$4\n", $reg, $val; } elsif (m/(.*)em28xx_write_regs\(dev\,\s*(.*)\,\s*\"\\x(..)\",\s*1\)\;(.*)/) { my $reg = $2; my $val = $3; $val =~ tr/A-f/a-f/; $reg = $reg_map{$reg} if defined($reg_map{$reg}); printf "$1em28xx_write_reg(dev, %s, 0x%s);$4\n", $reg, $val; } else { print $_; } } Signed-off-by: -

Since saa7115 has saa711x chip auto-detection, there's no need on differenciating it at cards table. Just use the generic name for all boards that use a philips saa711x decoder. Signed-off-by: -

Several fields are duplicated on both structs. Let's just copy em28xx_board instead. A later cleanup could just copy the fields that are changed, in order to keep em28xx_board const. Signed-off-by: -

Remove unused em28xx_board.vchannels and em28xx.video_channels. Also, .is_em2800 = 0 is not needed, as all data is zeroed by kernel loader. The table also included a notice that svideo weren't test on Hauppauge USB2. Remove this notice, since this input also works properly. Also, it does some whitespace cleanups. Signed-off-by: -

The previous patches removed XCLK and I2C magic. Now, we finally know what those registers do. Also, only a very few cards need different setups for those. Instead of keeping the setups for those values inside the per-device hack magic switch, move the uncommon values to the board-specific struct, and have a common setup for all other boards. So, almost 100 lines of hacking magic were removed. A co-lateral effect of this patch is that it also fixes a bug at em28xx-core, where xclk were set, without taking any care about not overriding a previous xclk setup. Signed-off-by: -

The OmniVision OV534 is the USB bridge chip used in Sony Playstation EYE, it is found also in other webcams like Hercules Blog Webcam and Hercules Dualpix HD. This driver is the port to gspca of a prototype driver by Mark Ferrell based on vivi. The original code to initialize the camera and start the capture is from Jim Paris on ps2dev.org, here integrated with the analysis of the USB communications taken by the windows driver.
