This example driver uses all the latest frameworks and can serve as a starting point for a new V4L2 PCI driver. Originally written for a presentation on how to use V4L2 frameworks during FOSDEM 2014. Signed-off-by:

The calculated values for the minlen and maxlen fields, which were rounded to multiples of 2 and clamped to a valid range, were left unused. Use them in the calculation of the register value rather than using the raw input minlen and maxlen. This fixes the following warning with a W=1 build: drivers/media/rc/img-ir/img-ir-hw.c In function ‘img_ir_free_timing’: drivers/media/rc/img-ir/img-ir-hw.c +228 :23: warning: variable ‘maxlen’ set but not used [-Wunused-but-set-variable] drivers/media/rc/img-ir/img-ir-hw.c +228 :15: warning: variable ‘minlen’ set but not used [-Wunused-but-set-variable] Reported-by:

The JVC timings included timings intended for the secondary decoder (which matches messages with no leader), however they were in the wrong part of the timings structure, repeating s00 and s01 rather than being in s10 and s11. Distinct repeat timings can't be properly supported yet for JVC anyway since the scancode callback cannot determine which decoder matched the message, so for now remove these timings and don't bother to enable the secondary decoder. This fixes the following warnings with W=1: drivers/media/rc/img-ir/img-ir-jvc.c +76 :3: warning: initialized field overwritten [-Woverride-init] drivers/media/rc/img-ir/img-ir-jvc.c +76 :3: warning: (near initialization for ‘img_ir_jvc.timings.s00’) [-Woverride-init] drivers/media/rc/img-ir/img-ir-jvc.c +81 :3: warning: initialized field overwritten [-Woverride-init] drivers/media/rc/img-ir/img-ir-jvc.c +81 :3: warning: (near initialization for ‘img_ir_jvc.timings.s01’) [-Woverride-init] Reported-by:

RTL2832 driver provides muxed I2C adapters for tuner bus I2C gate control. Pass those adapters to rtl2832_sdr and e4000 modules in order to get rid of proprietary DVB .i2c_gate_ctrl() callback use. Signed-off-by:

Implement SDR driver for Realtek RTL2832U chip as a DVB extension module. SDR module is attached by DVB USB RTL28XXU driver as a DVB SEC (satellite equipment controller) module. Abusing unused SEC here has no harm as that is DVB-T only frontend. SDR functionality is provided by RTL2832 DVB-T demodulator. I suspect it is originally planned for DAB and FM, but it could be abused general SDR, due to modern silicon tuners that has wide frequency range and a lot of configurable parameters (filters, gains, ...). http://thread.gmane.org/gmane.linux.drivers.video-input-infrastructure/44461Signed-off-by:

There was 32-bit overflow on VCO frequency calculation which blocks tuning to 1073 - 1104 MHz. Use 64 bit number in order to avoid VCO frequency overflow. After that fix device in question tunes to following range: 60 - 1104 MHz 1250 - 2207 MHz Signed-off-by:

Add volatile boolean control to indicate if tuner frequency synthesizer is locked to requested frequency. That means tuner is able to receive given frequency. Control is named as "PLL lock", since frequency synthesizers are based of phase-locked-loop. Maybe more general name could be wise still? Cc: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by:
