Three really tiny minors in this single commit which all on their own would just clutter up the commit history unnecessarily: * ddbridge-regs.h is lacking an include guard. Add it. * Fix an unnecessary NULL initialisation in ddbridge-ci.

2018-05-04media: cxd2880-spi: avoid out-of-bounds access warningArnd Bergmann1-17/+7
The -Warray-bounds warning in gcc-8 triggers for a newly added file: drivers/media/spi/cxd2880-spi.c: In function 'cxd2880_write_reg': drivers/media/spi/cxd2880-spi.c:111:3: error: 'memcpy' forming offset [133, 258] is out of the bounds [0, 132] of object 'send_data' with type 'u8[132]' {aka 'unsigned char[132]'} [-Werror=array-bounds] The problem appears to be that we have two range checks in this function, first comparing against BURST_WRITE_MAX (128) and then comparing against a literal '255'. The logic checking the buffer size looks at the second one and decides that this might be the actual maximum data length. This is understandable behavior from the compiler, but the code is actually safe. Since the first check is already shorter, we can remove the loop and only leave that. To be on the safe side in case BURST_WRITE_MAX might be increased, I'm leaving the check against U8_MAX.

Show the UCB error counts via DVBv5. Please notice that there's no scale indication at the driver. As we don't have the datasheet, let's assume that it is receiving data at a rate of 10.000 packets per second. Ideally, this should be read or estimated. In order to avoid flooding I2C bus with data, the maximum polling rate for those stats was set to 1 second.

Implement frontend attachment as ddb_fe_attach_mci() into the ddbridge-max module. The MaxSX8 MCI cards are part of the Max card series and make use of the LNB controller driven by the already existing lnb functionality, so here's where this code belongs to.

2018-05-04media: ddbridge: initial support for MCI-based MaxSX8 cardsDaniel Scheller3-1/+703
This adds initial support for the new MCI-based (micro-code interface) DD cards, with the first one being the MaxSX8 eight-tuner DVB-S/S2/S2X PCIe card. The MCI is basically a generalized interface implemented in the card's FPGA firmware and usable for all kind of cards, without the need to implement any demod/tuner drivers as this interface "hides" any I2C interface to the actual ICs, in other words any required driver is implemented in the card firmware. At this stage, the MCI interface is quite rudimentary with things like signal statistics reporting missing, but is already working to serve DVB streams to DVB applications. Missing functionality will be enabled over time. This implements only the ddbridge-mci sub-object and hooks it up to the Makefile so the object gets build. The upcoming commits hook this module into all other ddbridge parts where required, including device IDs etc. Picked up from the upstream dddvb-0.9.33 release.

2018-05-04media: ddbridge: support dummy tuners with 125MByte/s dummy data streamDaniel Scheller3-0/+38
The Octopus V3 and Octopus Mini devices support set up of a dummy tuner mode on port 0 that will deliver a continuous data stream of 125MBytes per second while raising IRQs and filling the DMA buffers, which comes handy for some stress, PCIe link and IRQ handling testing. The dummy frontend is registered using dvb_dummy_fe's QAM dummy frontend. Set ddbridge.dummy_tuner to 1 to enable this on the supported cards. Picked up from the upstream dddvb-0.9.33 release.
