This adds an soc-camera / v4l2-subdev driver for the RJ54N1CB0C CMOS camera sensor from Sharp. The sensor is very picky about initialisation and configuration sequences. The driver limits artificially maximum window size by 800x600, although the sensor supports 1600x1200. Sizes above 800x600 don't seem to work correctly, besides, examples from the system integrator use sizes above 640x480 only for still photography. Unfortunately, I had to use "magic" register-value pairs for undocumented and "reserved" registers. This version of the driver also omits some functionality, like cropping, which hasn't been sufficiently tested yet and will be added later. create mode 100644 drivers/media/video/rj54n1cb0c.c Signed-off-by:

The length check in reg_w_var() function is because the buffer contents is copied to gspca_dev->usb_buf which has the size of USB_BUF_SZ bytes as defined in drivers/media/video/gspca/gspca.h. Replace the number with symbol for better readability and maintainability. Signed-off-by:

This changes adds IR Rx keypress input event handling to the CX23885 module. This change specifically only adds input handling for IR devices implemented as v4l2_subdevices, using only the pulse width mode (for now), and only with RC-5 remotes. The V4L-DVB infrastructure is missing too much to support RC-6 mode 6A as used in many media center remotes. The grey Hauppauge RC-5 remote and HVR-1850 IR receiver work now. Signed-off-by:

This change completes the v4l2_subdev implementation for IR receive for the IR controller built into the CX23888. This changes almost completes the IR transmit side also, but doesn't. Instead notes in the comments describe what needs to be done for IR Tx to work in the subdevice implementation. The current Tx behavior is skeletal and benign. If left alone, it does nothing. It will only ever generate a Tx interrupt on Tx init by a caller or when the tx_write() method is called. The ISR, when called, will then disable the Tx FIFO service interrupt. Signed-off-by:

For the IR controller on the CX23888 to work for the HVR-1850 and in general, the A/V core must be initialized to get the VID_CLK going. The VID_CLK is the timing reference for the CX23888's integrated IR controller. Signed-off-by:

The SYS and AUX PLLs need to be initialized to different values based on the chip: CX23885, CX23887, CX23888, as each uses a different crystal frequency: 28.6363 MHz, 25.0 MHz, 50.0 MHz. Signed-off-by:

Separate out the set_audclk_freq() function into separate functions for the four families of cores. These cores all use slightly different sample clock schemes and may be assuming slightly (+/- 3 Hz) different reference frequencies. The code resuse was not worth the maintenance and testing headache of have all chips use the same function peppered with conditional logic. Added comments on how PLL and SRC parameters values are computed. Fixed a few bugs related to the shared code having a large number of conditional statements. Noted inconsistencies with FIXME in the comments. This is done in preparation for getting the CX2388[578] PLL/clock setting logic cleaned up for CX23888 analog video and IR (which need the VID PLL set right). Signed-off-by:

Change logic to check for various chip or core families to inline functions. Checks for specific chips should be made against the state->id field now. This is in preparation for chip/core specific code for setting up PLLs for the CX2388[578] family of cores, that all run with different crystal frequencies. Signed-off-by:

Add improved logic to detect the exact CX2388[578] A/V core that is being probed. Also cleaned up detection and logging for CX2310[12], CX2583[67], and CX2584[0123] cores and chips. Also added code to identify a CX2388[578] A/V decoder core that is not responding properly. Typical symptoms include registers 0x00-0xff responding properly but all other registers returning the same value (0x13 and 0x5 have been observed). This state will cause proper detection of '885 vs. '887 vs. '888 to fail and the chip won't respond to get configured properly anyway. I have no method of reseting the core to a working state at this time; but I didn't try too hard to work one out either. The problem likely only occurs in development. I suspect configuring the SYS PLL VCO to oscillate too slowly (286.3 MHz?) before post divide may be the root cause, when encountered. Signed-off-by:

This change adds a skeletal implementation of a v4l2_subdevice to provide encapsulation and abstraction of the CX23888's integrated consumer infrared controller. This change also instantiates the cx23888_ir subdev for the HVR-1850 which has IR hardware physically wired up to a CX23888. The cx23888_ir subdev code is being written with long-term objectives to: 1. port it to the cx25840 module for the CX2584x, CX2583x, CX23885, & CX231xx IR controllers 2. possibly port it to the cx18 module for the CX23418 IR controller 3. have the IR subdevice accessed abstractly in the cx23885 module, so the driver can ignore the difference between the CX23885 and CX23888.

This changes corrects the ioctl() operations for both the CX2388[578] analog video and MPEG video device nodes to properly and consistently support VIDIOC_G_CHIP_IDENT, VIDIOC_DBG_G_REGISTER and VIDIOC_DBG_S_REGISTER ioctl()s. This caused some ioctl() support routines to be broken out into a separate source file. Now v4l2-dbg can be used to manipulate CX2388[578] and CX23417 registers including the CX2388[57] functions handled by the cx25840 module. This was done in anticipation of developing a new v4l2_subdev for the integrated IR controller of the CX23888. Signed-off-by:
