The embedded UART is apparently used to receive decoded IR (RC5?) codes. Forward these scan codes to the RC framework and (where known) add corresponding mapping tables to translate them into regular keys. This patch has been tested on a TechniSat CableStar HD2. The mappings of other rc-maps were taken from Christoph Pinkl's patch (http://patchwork.linuxtv.org/patch/7217/) and the s2-liplianin repository. The major difference to Christoph's patch is a reworked interrupt handling of the UART because the RX interrupt is apparently level triggered and requires masking until the FIFO is read by the UART worker.

In little endian cases, macro cpu_to_be16 unfolds to __swab16 which provides special case for constants. In big endian cases, __constant_cpu_to_be16 and cpu_to_be16 expand directly to the same expression. So, replace __constant_cpu_to_be16 with cpu_to_be16 with the goal of getting rid of the definition of __constant_cpu_to_be16 completely. The semantic patch that performs this transformation is as follows: @@expression x;@@ - __constant_cpu_to_be16(x) + cpu_to_be16(x) Signed-off-by:

Statistics polling can not be done by lmedm04 driver's implementation of M88RS2000/TS2020 because I2C messages stop the device's demuxer, so allow polling for statistics to be suppressed in the ts2020 driver by setting dont_poll in the ts2020_config struct. Reported-by:

Provide a DVBv5 API signal strength. This is in units of 0.001 dBm rather than a percentage. >From Antti Palosaari's testing with a signal generator, it appears that the gain calculated according to Montage's specification if negated is a reasonable representation of the signal strength of the generator. To this end: (1) Polled statistic gathering needed to be implemented in the TS2020 driver. This is done in the ts2020_stat_work() function. (2) The calculated gain is placed as the signal strength in the dtv_property_cache associated with the front end with the scale set to FE_SCALE_DECIBEL. (3) The DVBv3 format signal strength then needed to be calculated from the signal strength stored in the dtv_property_cache rather than accessing the value when ts2020_read_signal_strength() is called.

The TS2020 and TS2022 tuners take an input from the demodulator indicating the AGC setting on that component that is then used to influence the tuner's own gain. This should be taken into account when calculating the gain and signal strength. Further, the existing TS2020 driver miscalculates the signal strength as the result of its calculations can exceed the storage capacity of the 16-bit word used to return it to userspace. To this end: (1) Add a callback function (->get_agc_pwm()) in the ts2020_config struct that the tuner can call to get the AGC PWM value from the demodulator. (2) Modify the TS2020 driver to calculate the gain according to Montage's specification with the adjustment that we produce a negative value and scale it to 0.001dB units (which is what the DVBv5 API will require): (a) Callback to the demodulator to retrieve the AGC PWM value and then turn that into Vagc for incorporation in the calculations. If the callback is unset, assume a Vagc of 0. (b) Calculate the tuner gain from a combination of Vagc and the tuner's RF gain and baseband gain settings. (3) Turn this into a percentage signal strength as per Montage's specification for return to userspace with the DVBv3 API. (4) Provide a function in the M88DS3103 demodulator driver that can be used to get the AGC PWM value on behalf of the tuner. (5) The ts2020_config.get_agc_pwm function should be set by the code that stitches together the drivers for each card. For the DVBSky cards that use the M88DS3103 with the TS2020 or the TS2022, set the get_agc_pwm function to point to m88ds3103_get_agc_pwm. I have tested this with a DVBSky S952 card which has an M88DS3103 and a TS2022. Thanks to Montage for providing access to information about the workings of these parts. Signed-off-by: -

ts2020_attach() allocates a variable pdata on the stack and then passes a pointer to it to i2c_new_device() which stashes the pointer in persistent structures.

struct timeval uses a 32-bit seconds representation which will overflow in the year 2038 and beyond. This patch replaces the usage of struct timeval with ktime_t which is a 64-bit timestamp and is year 2038 safe. This patch is part of a larger attempt to remove all instances of 32-bit timekeeping variables (timeval, timespec, time_t) which are not year 2038 safe, from the kernel.

The flexcop bridge chip has two banks of hardware pid filters - an initial 6, and on some chip revisions an additional bank of 32. A bug is present on the initial 6 - when changing transponders one of two PAT packets from the old transponder would be included in the initial packets from the new transponder. This usually transpired with userspace programs complaining about services missing, because they are seeing a PAT that they would not be expecting. Running in full TS mode does not exhibit this problem, neither does using just the additional 32. This patch adds in an option to not use the inital 6 and solely use just the additional 32, and enables this option for the SkystarS2 card. Other cards can be added as required if they also have this bug. Signed-off-by:

My static checker detected that free_irq() is called even after request_irq() failed in ddb_probe(). In this case, the kernel may try to free dev->pdev->irq although the IRQ is not assigned. This event rarely occurs, but always introduces a warning if it happens. "goto fail1" always results in disabling enabled MSI and releasing a requested IRQ. It seems like the former handling is necessary. So I added a conditional branch before the free_irq() (stat == 0 means request_irq() succeeds). Signed-off-by:

'struct timeval last_tv' is used to get the time of last signal change and 'struct timeval last_intr_tv' is used to get the time of last UART interrupt. 32-bit systems using 'struct timeval' will break in the year 2038, so we have to replace that code with more appropriate types. Here struct timeval is replaced with ktime_t. Signed-off-by:
