Whilst reanalysing my formulas I realised it was no longer possible to get the right values for a 36.1667MHz IF due to rounding problems. Storing frequencies in units of 0.1kHz makes it possible to calculate these again correctly. Signed-off-by:

There are at least three variants of the DViCO FusionHDTV DVB-T NANO that share the same USB device ID. The first (ZL10353 w/ firmware in ROM) is already supported; the latter two both require firmware and have either an MT352 or ZL10353 demodulator, and have a different IR receiver from the first. This introduces a new identify_state that can tell the difference between a "warm" device which is running the embedded firmware, and a "cold" device that needs us to upload firmware to it before it will work. We patch the uploaded device ID (like we do for other bluebird devices) to make it easy to identify the particular device variant when it reattaches. NB: These devices use a different firmware file from previous bluebird devices. You need a new firmware file to make this work. Signed-off-by: -

Rework the input frequency calculation so that it produces the right values when the ADC oversamples the IF input. This means MT352 devices can now process a near-zero IF (according to the, specs 4.57MHz is supported with the default crystal). Signed-off-by:

Add support for the DViCO FusionHDTV DVB-T NANO with zl10353 demodulator and firmware in ROM on the device. Again, this is based on the great work of Mike Krufky with my modifications to use the in-tree XC2028 driver. Signed-off-by:

When searching for standard-specific analog firmware, only certain type bits are valid, much like for DTV. Mask them off when finding the firmware to load. Signed-off-by:

Add support for DViCO's Dual Digital 4 with xc3028 tuner, zl10353 DVB-T demodulator and a new-style I2C IR remote control receiver. This would not have been possible without the work of and advice from Mike Krufky, who originally got the Dual Digital 4 and second-gen DVB-T NANO devices working with the out-of-tree XC3028 driver. I converted it to use the in-tree XC3028 driver (after making it suitable for our use), and added the IR remote control support based on his advice. NB: a firmware package is required to use this device. Signed-off-by:

In practice, the tuner occasionally fails to respond correctly after a firmware load. Retry the firmware load if the firmware/hardware version we read back from the tuner after programming does not match what we expect. Signed-off-by:

Define a list of valid "firmware types" for each combination of BASE, DTV and SCODEs. By masking the appropriate firmware bits off we can just use one "type" for the firmware searching and also flag when we are looking for a BASE, DTV or SCODE type firmware. This makes it much easier to track if we need to change device modes or flash an individual firmware part. Add a structure to remember what firmware properties we have. This contains the currently loaded/wanted base firmware (type), video std (id), video std requested (std_req), scode file and number in use. Incorporate said structure into the tuner private data. When checking whether the current firmware needs to be reloaded, first figure out exactly what "type" of firmware we want (base, std and scode), and then proceed to load the appropriate matching base, std-specific and scode records iff there are any changes required. This removes guesswork from the process because we no longer need to individually code a check for every tuning parameter's interactions. Signed-off-by:

Rather than picking the first video standard firmware that supports any of the standards that the user has requested, try to select one that supports as many of them as possible. This improves the likelihood that the firmware we select will support the user's desired TV standard. Signed-off-by:

There is no need to duplicate the max_len field from the ctrl structure in the private data. If we use it directly from priv->ctrl, we can memcpy the structure (apart from strings) to reduce maintenance as it grows. Enforce a minimum max_len length of 8 data bytes (+ 1 address byte) as seems to be required by the tuner. Also, use kstrdup instead of open coding the string duplication. Signed-off-by:

7MHz bandwidth DVB-T needs an adjusted offset at the PLL to ensure the IF output is correctly centered. Signed-off-by:
-
Chris Pascoe authored
We were using priv->bandwidth to select the base firmware to load, not the requested bandwidth value, oops. Also, 7MHz Digital TV needs 8MHz base firmware loaded. Signed-off-by:

Hold the private lock over set_config and set priv->firm_size to 0 after a failed firmware load to prevent firmware accidentally being freed on us. Clean up the firmware load/error messages somewhat and rename priv->version to priv->firm_version to make it clear which "version" it is. Signed-off-by:

Issuing register reads as a separate address write and data read transactions means that other I2C activity could occur in between and state could get out of sync. Issue both the write and read in a single transaction so that the i2c layer can prevent other users accessing the bus until we are complete. Signed-off-by:

The path to perform a read immediately after a write was not checking that the address being read from was the same as the one that was written. Handling this case correctly should mean that we now can handle more than two i2c messages at a time. Signed-off-by:

Any i2c read request that was not immediately preceded by a write request was incorrectly taking the write path. Add the capability to handle individual read requests. Signed-off-by:

The HVR-900 requires the MTS version of the xc3028 firmware in order to get any sound. The below patch selects this firmware variant on HVR-900 cards, as well as splitting the HVR-950 into its own entry (since I don't know if it uses the MTS variant and it will have to be split off eventually anyway).
