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: Andy Walls

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: Andy Walls

Add v4l2_subdev_ir_ops and IR notify defines for v4l2_device. This change
is specifically needed at this time to support the integrated IR controller in
the CX2388[58] chips.Signed-off-by: Andy Walls

The prior mechanism wasn't reliable with the cx23887. This new mechanism

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: Andy Walls

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: Andy Walls

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: Andy Walls

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: Andy Walls

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: Andy Walls

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.Signed-off-by: Andy Walls

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: Andy Walls

Add identifiers for CX2388[578] chips, CX2310[012] chips, integrated
A/V decoders cores, integrated IR controller core, and the CX23417
MPEG encoder. The cx23885 module and cx25840 module will use these
identifiers in upcoming changes.Signed-off-by: Andy Walls

XS (em2882).Note by djh: Thanks go out fo Andrej Suligoi for his contribution in providing
and testing pretty much the exact same patch as provided by Uros. Between
the two of them, they got all the core functionality working for the device.Cc: Andrej Suligoi

Seems that the reference design used for the KWorld 2800d switched from the
em2860 to em2862, so we need to add the new USB id (and the i2c hash remains
so all we need is the default em2862 id.Thanks to Ian Young for reporting the issue and testing the fix.
