From: Mauro Carvalho Chehab <>

Hi Linus,

Please pull from:
  git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media v4l_for_linus

On patch series:
    - Missing MAINTAINERS entries were added for several drivers;
    - Adds V4L2 support for DMABUF handling, allowing zero-copy buffer
      sharing between V4L2 devices and GPU;
    - Got rid of all warnings when compiling with W=1 on x86;
    - Add a new driver for Exynos hardware (s3c-camif);
    - Several bug fixes, cleanups and driver improvements;

Thanks!
Mauro

Naked hardware #6: ezcap USB 2.0 DVB-T Stick

How I end up hacking that device

Initially, few years back to 2009, I was hacking the Realtek RTL2831U Linux support. It is predecessor of RTL2832U having very much similarities, but supports only quite old traditional RF-tuners (reference design tuners seen are QT1010, MT2060, MXL5003S). It appeared very beginning that there is new version (RTL2832U) on the marked. I got one, from Verkkokauppa.com, which was RTL2832U + FC2580. I compared those chipset and saw there is much similarities, even so much that I first tried to make all that supported by two drivers: one for USB-interface and one for demodulator. At the some point I still made a decision (RTL2830/RTL2832) demodulators are too different and dropped out RTL2832 support from common demodulator driver. USB interface driver still remains common for both of these chips. Later Thomas Mair jumped in and made missing driver for RTL2832 demodulator.

All in all, these two chips are supported currently with following driver combinations:
RTL2831U: dvb_usb_rtl28xxu + rtl2830
RTL2832U: dvb_usb_rtl28xxu + rtl2832

My first RTL2832U +  FC2580 device didn't support FM radio. Support for radio was asked few times and I finally decided to order one during autumn 2011 from the DealExtreme. It is just that device seen on that post.

Realtek RTL2832U

Realtek RTL2832U

Realtek RTL2832U is integrated USB interface and DVB-T demodulator. Demodulator which is integrated to that chip is Realtek RTL2832 (note the difference between RTL2832 vs. RTL2832U, the extra 'U' at the and of chip model number means USB interface). RTL2832 is sold as a separate chip too.

Currently RTL2832U is absolutely most common USB DVB-T chip. I could guess it is due to cheap price, vendor provided reference designs with a huge amount of supported RF tuners and also vendor provided Linux driver. One notable thing for popularity is surely also possibility of use it as a poor man's SDR.

RTL2832U chip is the largest chip seen in that picture. 8 pin chip, T24C02A, on the left side of PCB is 2k serial eeprom. As usually, that eeprom contains some hardware configuration information for the RTL2832U. There is also 28.800MHz crystal which is clock source. IR -receiver was attached just top of RTL2832U, but on that picture I bent it to standing position for better view of RTL2832U.

There is older model of that chip which is called RTL2831U, having quite same USB -interface but different demodulator named RTL2830. Due to that same Linux USB interface driver is used for both RTL2832U and RTL2831U.
RTL2831U: dvb_usb_rtl28xxu + rtl2830
RTL2832U: dvb_usb_rtl28xxu + rtl2832

RTL2832U SDR mode

One absolutely very interesting feature of that chip is so called SDR (Software-defined radio) mode. That undocumented mode is used to offer FM radio and DAB features, whilst DVB-T is demodulated traditionally by hardware. RTL2832U with a comibination of RF-tuner which supports very wide range frequencies (around 50-2000MHz) makes that device very interesting as a general poor man's SDR.

Elonics E4000

Elonics E4000

Elonics E4000 could be seen clearly center of that picture. 28.800MHz crystal is clock source for both E4000 and RTL2832U. There is four clearly visible wires, going through C11/C12/C13/C17, between tuner and demodulator. It is baseband (Zero-IF, 4 wires) I/Q signal interface which goes to the demodulator ADC.

E4000 is multi-mode direct conversion (aka Zero-IF) silicon RF-tuner. It supports wide range of different standards. Due to wide range of supported radio communication standards, it supports wide frequency range that makes it quite interesting RF tuner. Currently, I don't know any other DVB-T tuner which supports that large frequency range.

Afatech AF9015

Afatech AF9015

There is two visible square dints on that metal plate. AF9015 is under the dint which is quite center of that picture, near USB-connector and just beside 8pin IC which is clearly visible. That 8pin IC is 2k serial eeprom, markings are ISSI 635 402B2GLI. As usually, eeprom is used for storing device specific information, notably USB ID and USB strings. AF9015 uses eeprom for storing a lot of board specific information too. For example dual mode, remote controller type, remote controller protocol, used RF-tuner, intermediate frequency (IF between demod and tuner). AF9015 clocked at 12.000 MHz. Crystal is located on the other side of the PCB.

AF9015 is quite popular USB DVB-T chip. It integrates DVB-T demodulator named AF9013. Firmware (dvb-usb-af9015.fw) is needed in order to operate. AF9015 firmware contains firmware for both AF9015 and AF9013. Chips has hardware PID filters which means it supports USB1.1 too.

Among the all typical features of DTV USB-interface there is one which is not so typical. That feature is support for two simulatanous television streams. There is external serial transport stream interface that could be used for connecting external demodulator. You could connect one external AF9013 demodulator to that chip which means there is total of two AF9013 demodulators as one is already integrated! That feature offers easy support for dual tuner devices.

AF9005 is predecessor and AF9035 is successor of that chip.

Afatech AF9013

AF9013 is just basic DVB-T demodulator and nothing more. That device in question is a little bit special as it has two tuners "dual tuner". As explained earlier, one AF9013 is integrated to AF9015 and the other is on separate chip. That not-integrated AF9013 is located under the dint just center of that picture. AF9013 needs firmware. In case of AF9013 integrated to AF9015 that firmware is carried with the AF9015 firmware.

MaxLinear MxL5003S

MaxLinear MxL5003S

Unfortunately MxL5003S RF-tuners are hidden under that metal plate. There is two MxL5003S tuners as this device is dual tuner model. Tuners are clocked at 16 MHz, crystal is likely under the metal plate too.


MxL5003S is very typical digital television silicon tuner. Absolutely nothing special to mention.

There is more feature rich model MxL5005S that supports analog too. MxL5003S and MxL5005S are same silicon design - MxL5005S driver could ran MxL5003S too.
