The firedtv DVB driver will now work not only on top of the old ieee1394
driver stack but also on the new firewire driver stack.

Alongside to the firedtv-1394.c backend for driver binding and I/O, the
firedtv-fw.c backend is added.  Depending on which of the two 1394
stacks is configured, one or the other or both backends will be built
into the firedtv driver.

This has been tested with a DVB-T and a DVB-C box on x86-64 and x86-32
together with a few different controllers (Agere FW323, a NEC chip, TI
TSB82AA2, TSB43AB22/A, VIA VT6306).

firedtv: reinstate debug logging option

    Henrik Kurelid tells me that FCP debug logging (which I removed during
    cleanups) is still useful when working on driver issues together with
    end users.  So bring it back in an updated form with only 60% of the
    original code footprint.

    Logging can be enabled with
    # echo -1 > /sys/module/firedtv/parameters/debug

    1 instead of -1 enables only FCP header logging,
    2 instead of -1 enables only hexdumps of the entire FCP frames.
    0 switches logging off again.

firedtv: dvb demux: more compact channels backing store

    Replace struct firedtv_channel { bool active; int pid; } channel[16];
    by unsigned long channel_active; u16 channel_pid[16];.

Sun Feb 15 15:33:17 CET 2009
firedtv: dvb demux: some simplifications

    c->active was unnecessarily cleared twice.

    Also, by marking the channel inactive before the for loop,
    the loop becomes identical with fdtv_channel_collect().

Sun Feb 15 15:33:17 CET 2009
firedtv: dvb demux: remove a bogus loop

    This loop is unnecessary because
      - only active channel[].pid's will be sent to the device,
      - when a channel is activated, its pid is set to dvbdmxfeed->pid.

    Perhaps the original code was there because it was initially not fully
    covered by the fdtv->demux_mutex.

firedtv: dvb demux: fix mutex protection

    fdtv_start_feed() accessed the channel list unsafely.

firedtv: dvb demux: fix missing braces

    Original code was:
            ...
            case DMX_TS_PES_OTHER:
                    //Dirty fix to keep firesat->channel pid-list up to date
                    for(k=0;k<16;k++){
                            if(firesat->channel[k].active == 0)
                                    firesat->channel[k].pid =
                                            dvbdmxfeed->pid;
                                    break;
                    }
                    channel = firesat_channel_allocate(firesat);
                    break;
            default:
            ...

    Looks bogus in several respects. For now let's just add braces to the if
    because that seems to be what the author meant.

firedtv: avc: reduce stack usage, remove two typedefs

    It is safe to share a memory buffer for command frame and response frame
    because the response data come in after the command frame was last used.

    Even less stack would be required if only the actual required frame size
    instead of the entire FCP register size was allocated.

    Also, rename the defined types AVCCmdFrm and AVCRspFrm to
    struct avc_command_frame and struct avc_response_frame.
    TODO:  Remove the bitfields in these types.

firedtv: fix remote control input

    and update the scancode-to-keycode mapping to a current model.  Per
    default, various media key keycodes are emitted which closely match what
    is printed on the remote.  Userland can modify the mapping by means of
    evdev ioctls.  (Not tested.)

    The old scancode-to-keycode mapping is left in the driver but cannot be
    modified by ioctls.  This preserves status quo for old remotes.

firedtv: replace semaphore by mutex

    firesat->avc_sem and ->demux_sem have been used exactly like a mutex.
    The only exception is the schedule_remotecontrol tasklet which did a
    down_trylock in atomic context.  This is not possible with
    mutex_trylock; however the whole remote control related code is
    non-functional anyway at the moment.  This should be fixed eventually,
    probably by turning the tasklet into a worqueue job.

    Convert everything else from semaphore to mutex.

    Also rewrite a few of the affected functions to unlock the mutex at a
    single exit point, instead of in several branches.
