This file does an ugly binding between drxj and DVB frontend. Remove most of the functions there. We still need to get rid of get_frequency and set_frequency, but such patch is a little more complex, as it should also remove some previous tuner bindings. Acked-by:

In order to avoid warnings and to remove dead code, remove the functions that don't make sense to happen, while commenting the others that might still be useful some day. That reduced a lot the text size: Before: text data bss dec hex filename 58419 2916 4 61339 ef9b drivers/media/dvb-frontends/drx39xyj/drx39xyj.ko After: text data bss dec hex filename 78331 2916 4 81251 13d63 drivers/media/dvb-frontends/drx39xyj/drx39xyj.ko Without any functional changes. It could be make sense latter to remove those drivers or to move them into an analog-specific part of the driver. Acked-by:

With this change, we finally got rid of all abstraction layers on this driver. This patch also fixes the LNA GPIO settings, as the original code were using a wrong control name for it. This patch exposes the several functions that aren't used. Some of them are related to analog demod that might be used some day, but others will likely never be needed, as they don't fit on Linux media APIs. Latter patches will clean up this mess. Acked-by:

While drxj is already too big, moving the code there will make easier to get rid of the drxj_ctrl function. It will also help to detect and remove the unused functions, helping to remove lots of dead code there. Acked-by:

This function is used only as an abstraction layer to call the two firmware functions. Remove it. As a bonus, the drx_ctrl_function is now unused and can be removed. Acked-by:

Remove the duplicated firmware upload code that was commented inside drxj.c. This code is not used, and will not work anyway, as it doesn't download the firmware from userspace. Acked-by:

The version is initialized with zero at drx_driver.c. Keep it, in order to avoid the risk of causing any regression. While here, remove the drx_driver.h from drxj, as this is not required there. Acked-by:

ClearQAM is currently not working. Add support for it too. Unlikely other ATSC tuners, though, this device will not auto-detect between ATSC and ClearQAM. So, the delivery system should be properly set. Also, this frontend seems to also support DVB-C annex A/C. Add experimental support for them. Acked-by:

Instead of hardcoding the firmware files together with the driver, use request_firmware() way, loading it from userspace. The firmware files are placed at: http://linuxtv.org/downloads/firmware/#8 And they'll be latter submitted to linux-firmware git tree. Acked-by:

There are several get/set macros that are bogus: they just call another macro and do either: x = FOO(d) or FOO(d) = x As checkpatch complains about that, and replacing all of them are as easy as running a small coccinelle script, get rid of all of them.

Instead of defining its own set of error codes, use the linux native ones. Please note that this patch made a "stupid" error code mapping, just replacing the codes with the closest one. In special, -EIO is being used on several places. I'm pretty sure this could be better assigned, but a change like that would require lots o time and efforts, without much benefit. So lets do adjstments at the error codes latter, when we have more time. Acked-by:

Fix almost all checkpatch.pl warnings/errors on drxj.c, except for: - 80 cols whitespacing; - too many leading tabs; - a false positive at DRXJ_16TO8() macro. - static char array declaration should probably be static const char as adding "const" would cause warnings. Acked-by:
