V4L/DVB (8097): xc5000: check device hardware state to determine if firmware download is needed

2008-06-26T18:58:58+00:00

This patch ensures that the xc5000 will have firmware loaded as needed if the
part is powered down or reset via gpio from the host. An example of this, in
some cases, could be after the system resumes from standby or hibernate modes.

V4L/DVB (8037): tda18271: ensure that the thermometer is off during channel configuration

2008-06-26T18:58:50+00:00

Having the thermometer on during channel configuration
could cause tuning instability.

V4L/DVB (8035): tda18271: dont touch EB14 if rf_cal lookup is out of range

2008-06-26T18:58:49+00:00

The TDA18271HD/C1 rf_cal map lookup is expected to go out of range outside
of the frequency window 41 MHz - 61.1 MHz.  In these cases, the internal
RF tracking filters calibration mechanism is used.

V4L/DVB (8034): tda18271: fix IF notch frequency handling

2008-06-26T18:58:48+00:00

The IF notch bit gets unset when we update the Main Post Div register
value, before we have a chance to write the desired IF notch setting
to the tuner.  Move the IF notch configuration to after we update MPD.

V4L/DVB (7983): tda18271_calc_rf_cal must return the return value of tda18271_lookup_map

2008-06-05T09:35:54+00:00

On the TDA18271HD/C1, we perform RF tracking filter correction for VHF low
band, only. If supplied a frequency out of range, the error must be returned
to the caller (tda18271c1_rf_tracking_filter_calibration) so that it can
decide whether or not to write to register EB14, RFC_CPROG[7:0]

V4L/DVB (7974): fix MEDIA_TUNER && FW_LOADER build error

2008-06-05T09:35:53+00:00

-tip testing found the following build failure:

  LD      .tmp_vmlinux1
  drivers/built-in.o: In function `generic_set_freq':
  tuner-xc2028.c:(.text+0xbd896): undefined reference to `request_firmware'
  tuner-xc2028.c:(.text+0xbdd7a): undefined reference to `release_firmware'
  drivers/built-in.o: In function `xc_load_fw_and_init_tuner':
  xc5000.c:(.text+0xc68e6): undefined reference to `request_firmware'
  xc5000.c:(.text+0xc6abe): undefined reference to `release_firmware'

with this config:

  http://redhat.com/~mingo/misc/config-Tue_May_20_18_11_34_CEST_2008.bad

the reason is another kconfig tool bug that has to be worked around in
the driver's Kconfig file: if FW_LOADER is selected in a second
dependency, that is not properly propagated up the dependencies.

in this case, FW_LOADER is selected from MEDIA_TUNER_XC2028:

  config MEDIA_TUNER_XC2028
        tristate "XCeive xc2028/xc3028 tuners"
        depends on VIDEO_MEDIA && I2C
        depends on HOTPLUG
        select FW_LOADER

which got selected by MEDIA_TUNER:

  config MEDIA_TUNER
        tristate
        default VIDEO_MEDIA && I2C
        depends on VIDEO_MEDIA && I2C
        select FW_LOADER if !MEDIA_TUNER_CUSTOMIZE && HOTPLUG

but the kconfig tool did not pick up this second-order dependency and
allowed CONFIG_FW_LOADER=m to be selected - in which case the build
fails.

the workaround i found was to move the select of FW_LOADER one level up,
so that the buggy kconfig tool can notice it and can act appropriately.
This problem can probably be worked around in other ways as well, i went
for the minimal fix.

Obviously, the kconfig tool should be fixed, it is not reasonable to
expect driver authors to do manual dependency resolution (that kconfig
itself already does) and uglify the Kconfig files. The kconfig tool did
nothing to warn about this situation and did not prevent this faulty
.config from being constructed.
