Check for i2c_algorithm structures that are only stored in the algo field of an i2c_adapter structure. This field is declared const, so i2c_algorithm structures that have this property can be declared as const also.

Return 0 instead of -EINVAL in get_frontend if no demod mode is active. This fixes ie. dvb-fe-tool getting confused and assuming a DVBv3 FE on idle frontends when the FE has been put to sleep using sleep(). Also, in read_status(), don't immediately return when no demod is active, so the remaining code has a chance to clear the signal statistics. Signed-off-by:

Adds a stv0910_single modparm which, when set, configures the stv0910 to run in single demodulator mode, currently intended for high bit rate testing. Signed-off-by:

This adds all required glue code to support - in conjunction with the new stv0910 and stv6111 demod/tuner drivers and additionally the lnbh25 LNB controller driver - all current DVB-S/S2 hardware (bridges and flex modules) from Digital Devices like the DD CineS2 V7 and V7A, current S2 V4 DuoFlex modules, and probably all upcoming devices based on this STV0910/STV6111/LNBH25 hardware stack.

Daniel Scheller authored
This adds a frontend driver for the ST STV6111 DVB-S/S2 tuners. Like the stv0910 demod frontend driver, this driver originates from the Digital Devices' dddvb vendor driver package as of version 0.9.29, and was cleaned up aswell. No functionality had to be removed though. Any camel case has been converted to kernel_case, fixup patch has been proposed upstream. Permission to reuse and mainline the driver code was formally granted by Ralph Metzler <rjkm@metzlerbros.de>. Signed-off-by:

Original code at least has some signed/unsigned issues, resulting in values like 32dBm. Implement signal strength readout to work without asking the attached tuner, and use a lookup table instead of log calc. Values reported appear plausible, gathered from feedback from several testers.

Implements stream_id filter and scrambling code setup in start() and also sets FE_CAN_MULTISTREAM in frontend_ops. This enables the driver to properly receive and handle multistream transponders, functionality has been reported working fine by testers with access to such streams, in conjunction with VDR on the userspace side. The code snippet originates from the original vendor's dddvb driver package and has been made working properly with the current in-kernel DVB core API. Signed-off-by:

Fixes smatch error: drivers/media/dvb-frontends/stv0910.c:715 dvbs2_nbch() error: buffer overflow 'nbch[fectype]' 2 <= 28 Also, fixes the nbch array table by adding the DUMMY_PLF element at the top to match the enums (table element order was off by one before).

This adds a multi frontend driver for the ST STV0910 DVB-S/S2 demodulator frontends. The driver code originates from the Digital Devices' dddvb vendor driver package as of version 0.9.29, and has been cleaned up from core API usage which isn't supported yet in the kernel, and additionally all obvious style issues have been resolved. All camel case and allcaps have been converted to kernel_case and lowercase. Patches have been sent to the vendor package maintainers to fix this aswell. Signal statistics acquisition has been refactored to comply with standards. Permission to reuse and mainline the driver code was formally granted by Ralph Metzler <rjkm@metzlerbros.de>.

We know this won't happen as the template name is always "usbvision", so we can easily avoid the warning as well by using this as the format string directly.

This patch enables support for non-Bluecherry labeled solo6110 based PCI cards which have 3 x TW2864B chips and one TW2865. These cards are displayed by lspci -nn as "Softlogic Co., Ltd. SOLO6110 H.264 Video encoder/decoder [9413:6110]" Bluecherry cards have 4 x TW2864A. According to datasheet register 0xFF of TW2864B chips contains value 0x6A or 0x6B depending on revision which being shifted 3 bits right gives value 0x0d. Existing version of solo6x10 fails on these cards with [276582.344942] solo6x10 0000:07:00.0: Probing Softlogic 6110 [276582.402151] solo6x10 0000:07:00.0: Could not initialize any techwell chips [276582.402781] solo6x10: probe of 0000:07:00.0 failed with error -22 Signed-off-by:

Provide support for the ADV7481 and ADV7482. The driver is modelled with 4 subdevices to allow simultaneous streaming from the AFE (Analog front end) and HDMI inputs though two CSI TX entities. The HDMI entity is linked to the TXA CSI bus, whilst the AFE is linked to the TXB CSI bus. The driver is based on a prototype by Koji Matsuoka in the Renesas BSP, and an earlier rework by Niklas Söderlund. Signed-off-by:
