In commit 567aba0b7997dad5fe3fb4aeb174ee9018df8c5b, the probe address
for tda8290_probe and tda8295_probe was hard-coded to 0x4b, which is the
default i2c address for those devices, but its possible for the device
to be at an alternate address, 0x42, which is the case for the HVR-1950.
If we probe the wrong address, probe fails and we have a non-working
device. We have the actual address passed into the function by way of
i2c_props, we just need to use it. Also fix up some copy/paste comment
issues and streamline debug spew a touch. Verified to restore my
HVR-1950 to full working order.
Special thanks to Ken Bass for reporting the issue in the first place,
and to both he and Gary Buhrmaster for aiding in debugging and analysis
of the problem.

There's a Realtek combo card reader and IR receiver device with multiple
usb interfaces on it. The mceusb driver is incorrectly grabbing all of
them. This change should make it bind to only interface 2 (patch based
on lsusb output on the linux-media list from Lucian Muresan).
Tested regression-free with the six mceusb devices I have myself.

The CIR Wake FIFO is 67 bytes long, but the stock remote appears to only
populate 65 of them. Limit comparison to 65 bytes, and wake from suspend
works a whole lot better (it wasn't working at all for most folks).
Fix based on comparison with the old lirc_wb677 driver from Nuvoton,

After upgrading the kernel from stock Ubuntu 7.10 to
10.04, with no hardware changes, I started getting the dreaded DMA
TIMEOUT errors, followed by inability to encode until the machine was
rebooted.
I came across a post from Andy in March
(http://www.gossamer-threads.com/lists/ivtv/users/40943#40943) where he
speculates that perhaps the corrective actions being taken after a DMA
ERROR are not sufficient to recover the situation. After some testing
I suspect that this is indeed the case, and that in fact the corrective
action may be what hangs the card's DMA engine, rather than the
original error.
Specifically these DMA ERROR IRQs seem to present with two different
values in the IVTV_REG_DMASTATUS register: 0x11 and 0x13. The current
corrective action is to clear that status register back to 0x01 or
0x03, and then issue the next DMA request. In the case of a 0x13 this
seems to result in a minor glitch in the encoded stream due to the
failed transfer that was not retried, but otherwise things continue OK.
In the case of a 0x11 the card's DMA write engine is never heard from
again, and a DMA TIMEOUT follows shortly after. 0x11 is the killer.
I suspect that the two cases need to be handled differently. The
difference is in bit 1 (0x02), which is set when the error is about to
be successfully recovered, and clear when things are about to go bad.
Bit 1 of DMASTATUS is described differently in different places either
as a positive "write finished", or an inverted "write busy". If we
take the first definition, then when an error arises with state 0x11,
it means that the write did not complete. It makes sense to start a
new transfer, as in the current code. But if we take the second
definition, then 0x11 means "an error but the write engine is still
busy". Trying to feed it a new transfer in this situation might not be
a good idea.
As an experiment, I added code to ignore the DMA ERROR IRQ if DMASTATUS
is 0x11. I.e., don't start a new transfer, don't clear our flags, etc.
The hope was that the card would complete the transfer and issue a ENC
DMA COMPLETE, either successfully or with an error condition there.
However the card still hung.
The only remaining corrective action being taken with a 0x11 status was
then the write back to the status register to clear the error, i.e.
DMASTATUS = DMASTATUS & ~3. This would have the effect of clearing the
error bit 4, while leaving the lower bits indicating DMA write busy.
Strangely enough, removing this write to the status register solved the
problem! If the DMA ERROR IRQ with DMASTATUS=0x11 is completely
ignored, with no corrective action at all, then the card will complete
the transfer and issue a new IRQ. If the status register is written to
when it has the value 0x11, then the DMA engine hangs. Perhaps it's
illegal to write to
DMASTATUS while the read or write busy bit is set? At any rate, it
appears that the current corrective action is indeed making things
worse rather than better.
I put together a patch that modifies ivtv_irq_dma_err to do the
following:
- Don't write back to IVTV_REG_DMASTATUS.
- If write-busy is asserted, leave the card alone. Just extend the
timeout slightly.
- If write-busy is de-asserted, retry the current transfer.
This has completely fixed my DMA TIMEOUT woes. DMA ERR events still
occur, but now they seem to be correctly handled. 0x11 events no
longer hang the card, and 0x13 events no longer result in a glitch in
the stream, as the failed transfer is retried. I'm happy.
I've inlined the patch below in case it is of interest. As described
above, I have a theory about why it works (based on a different
interpretation of bit 1 of DMASTATUS), but I can't guarantee that my
theory is correct. There may be another explanation, or it may be a
fluke. Maybe ignoring that IRQ entirely would be equally effective?
Maybe the status register read/writeback sequence is race condition if
the card changes it in the mean time? Also as I am using a PVR-150
only, I have not been able to test it on other cards, which may be
especially relevant for 350s that support concurrent decoding.
Hopefully the patch does not break the DMA READ path.
Mike
[awalls@md.metrocast.net: Modified patch to add a verbose comment, make minor
brace reformats, and clear the error flags in the IVTV_REG_DMASTATUS iff both
read and write DMA were not in progress. Mike's conjecture about a race
condition with the writeback is correct; it can confuse the DMA engine.]

This reverts commit 44835f197bf1e3f57464f23dfb239fef06cf89be.
With the CX23885 hardware I2C master, checking for I2C slave ACK/NAK
is not valid when the I2C_EXTEND or I2C_NOSTOP bits are set.
Revert the commit that checks for I2C slave ACK/NAK on all transactions,
so that XC5000 tuners work with the CX23885 again.
Thanks go to Mark Zimmerman for reporting and bisecting this problem.

With the current matching rules the lookup for rc protocol named rc-5-sz matches with "rc-5" before finding "rc-5-sz". Thus one is able to never enable/disable the rc-5-sz protocol via sysfs.

The streamzap driver has relatively low sampling resolution, and any
delays in reporting events seem to cause some minor problems for the
likes of irw when using the lirc bridge driver, resulting in a single
keypress registering as multiple independent ones, rather than as a
single press with repeats. If we call ir_raw_event_handle() more
frequently and reset the rawir kfifo at end-of-signal, the behavior
improves quite a bit.

Add the same "are you ready?" i2c_master_send() poll command to
get_key_haup_xvr found in lirc_zilog, which is apparently seen in
the Windows driver for the PVR-150 w/a z8. This stabilizes what is
received from both the HD-PVR and HVR-1950, even with their polling
intervals at the default of 100, thus the removal of the custom

Do not respond with -EINVAL to EVIOCGKEYCODE for not-yet-mapped
scancodes, but rather return KEY_RESERVED.
This fixes breakage with Ubuntu's input-kbd utility that stopped
returning full keymaps for remote controls.

The current hdpvr code kmalloc's a new buffer for every i2c read and
write. Rather than do that, lets allocate a buffer in the driver's
device struct and just use that every time.
The size I've chosen for the buffer is the maximum size I could
ascertain might be used by either ir-kbd-i2c or lirc_zilog, plus a bit
of padding (lirc_zilog may use up to 100 bytes on tx, rounded that up
to 128).
Note that this might also remedy user reports of very sluggish behavior
of IR receive with hdpvr hardware.

A number of things going on here, but the end result is that the IR part
on the hdpvr gets enabled, and can be used with ir-kbd-i2c and/or
lirc_zilog.
First up, there are some conditional build fixes that come into play
whether i2c is built-in or modular. Second, we're swapping out
i2c_new_probed_device() for i2c_new_device(), as in my testing, probing
always fails, but we *know* that all hdpvr devices have a z8 chip at
0x70 and 0x71. Third, we're poking at an i2c address directly without a
client, and writing some magic bits to actually turn on this IR part
(this could use some improvement in the future). Fourth, some of the
i2c_adapter storage has been reworked, as the existing implementation
used to lead to an oops following i2c changes c. 2.6.31.
Earlier editions of this patch have been floating around the 'net for a
while, including being patched into Fedora kernels, and they *do* work.
This specific version isn't yet tested, beyond loading ir-kbd-i2c and
confirming that it does bind to the RX address of the hdpvr.

Fixes an egregious bug in mceusb driver, where the receiver was being
put into idle mode far sooner than it should have, thanks to storing a
timeout value that in us where it should be ns. Basically, the receiver
kept going into idle mode before a trailing space had been fully
received, which was causing problems for some protocols, most notably
manifesting as lirc userspace never receiving a trailing space for any
rc5 signals.

Fix a bug in v4l2_device_unregister where the sd pointer can be dereferenced
after it was freed.
Normally the i2c adapter is removed before this function is called. Removing
the adapter will also unregister all subdevs on that adapter, so generally
v4l2_device_unregister has nothing to do. However, in the case of a platform
i2c bus that bus is generally not freed.
In that case, after freeing the i2c subdevice the code will fall into the
second block when it tests if the subdev is a SPI device. But by that time
the subdev is already freed and the kernel oopses.
The fix is trivial: continue with the loop after freeing the i2c or spi
subdevice.

Zeroing video_device.dev causes a memory leak if video_set_drvdata
was called before video_register_device was called. video_set_drvdata
calls dev_set_drvdata which allocates video_device.dev.p.
memsetting this will prevent freeing of that memory.

v4l2_queryctrl sets the step value based on the control type. That would
be fine if it used the control type stored in the V4L2 kernel control
object, not the one stored in the userspace ioctl structure that has
just been memset to 0. Fix this.

V4L2_CID_PRIVATE_BASE IDs
When queryctrl is called with a V4L2_CID_PRIVATE_BASE control ID, then
currently it is replaced by the real internal ID. This is not according to

This reverts a portion of commit
44243fc2ef99948bc9b046901880885616dd5e89
A commit for which I errantly recommended that defaults for I2C address
0x71 not be set by ir-kbd-i2c.c
The pvrusb2 and bttv drivers currently rely on ir-kbd-i2c setting
defaults for that address. Until I can get those bridge drivers fixed
to properly send IR_i2c_init_data for boards with Zilog Z8 chips,
just add back the default settings for I2C address 0x71.

After a recent update of xf86-input-evdev and xorg-server, I noticed
that X11 applications did not receive keypresses from the FireDTV
infrared remote control anymore. Instead, the Xorg log featured lots of
"FireDTV remote control: dropping event due to full queue!"
exclamations. The Linux console did not have an issue with the
FireDTV's RC though.
The fix is to insert EV_SYN events after the key-down/-up events.
