15 years agoPM: Introduce functions for suspending and resuming device interrupts
Rafael J. Wysocki [Mon, 16 Mar 2009 21:33:49 +0000 (22:33 +0100)]
PM: Introduce functions for suspending and resuming device interrupts

Introduce helper functions allowing us to prevent device drivers from
getting any interrupts (without disabling interrupts on the CPU)
during suspend (or hibernation) and to make them start to receive
interrupts again during the subsequent resume.  These functions make it
possible to keep timer interrupts enabled while the "late" suspend and
"early" resume callbacks provided by device drivers are being
executed.  In turn, this allows device drivers' "late" suspend and
"early" resume callbacks to sleep, execute ACPI callbacks etc.

The functions introduced here will be used to rework the handling of
interrupts during suspend (hibernation) and resume.  Namely,
interrupts will only be disabled on the CPU right before suspending
sysdevs, while device drivers will be prevented from receiving
interrupts, with the help of the new helper function, before their
"late" suspend callbacks run (and analogously during resume).

Convert this driver to v4l2_subdev. Note that currently the only card with
analog support in this driver is the HVR-1800. The analog tuner support in
this driver is limited to what is needed for this board. When analog support
is added for other cards, then the tuner load code will probably have to be
expanded to take care of those boards. For example, there is currently no
support for either radio tuners or tda9887 demods.

I'd like to thank Steven Toth for testing this on his HVR-1800.

V4L/DVB (11266): vino: Remove code for things already done by video_ioctl2

The v4l2-ioctl core only allows buffer types for which the corresponding
->vidioc_try_fmt_xxx() methods are defined to be used in vidioc_(g|s)_parm,
vidioc_(q|dq|query)buf, and vidioc_reqbufs.

Remove buffer type checking from vino_g_parm(), vino_s_parm(),
vino_reqbufs(), vino_querybuf(), vino_qbuf(), and vino_dqbuf().  This
reduced the indent level of the code so a few lines can be wrapped better.
Also fixed the C++ type comments.

The v4l2-ioctl core also provides structs that have been pre-zeroed for all
fields that driver is supposed to fill in, so remove zeroing code from
vino_enum_fmt_vid_cap().  Also, the format index is unsigned so it's not
necessary to check if it's less than zero.

TechnoTrend C-1501 DVB-C card does not lock on 388MHz. I assume that
existing frequency table is valid for DVB-T.

This is suggested by the name of the table: tda827xa_dvbt.

Added a table for DVB-C with the name tda827xa_dvbc.

Added runtime selection of the DVB-C table when the tuner is type
FE_QAM.

This should leave the behaviour of this driver with with DVB_T tuners
unchanged. This modification is in file tda827x.c

The tda827x.c gives the following warning message when debug=1:

tda827x: tda827x_config not defined, cannot set LNA gain!

Prefer the gspca sonixj driver for the Philips SPC600NC webcam instead of
the sn9c102 driver. As we've got userreports that it works with the gspca
