DVBv3 is a legacy API. Drivers should use DVBv5, in order to support modern applications. So, implement BER using dvbv5. Signed-off-by:

Use const on the static data, as gcc may optimize better the code. Also, would prevent that some code would override the data there. Signed-off-by:

As reported by smatch: drivers/media/dvb-frontends/cx24120.c: In function 'cx24120_message_send': drivers/media/dvb-frontends/cx24120.c:368:6: warning: variable 'ret' set but not used [-Wunused-but-set-variable] int ret, ficus; ^ The values written by cx24120 are never checked. So, remove the check here too. That's said, the best would be to do the reverse, but globally: to properly handle the error codes. Signed-off-by:

Add in all the likely values for setting fec on tuning. Some values yet to be tested but very likely to be correct. In the very unlikely event that these are wrong tuning with FEC_AUTO will still work. Signed-off-by:

If set, all the other drivers reset no_base_addr on failure to attach - git commit for this being added to some of them seems to be eccd15aa This driver has been floating around outside the mainline for so long it hasn't had this fix, so add it in. Whilst here tidy surrounding code to fix style issues. Signed-off-by:

Remove reg1 by refactoring for loops Change ret into an int as it's only used for return values now, and remove reset_result by using ret instead. Signed-off-by:

Use reg instead of ret for all calls to readreg, remove ret_EA as it doesn't need to be a separate var anymore. Signed-off-by:

Probably a remnant of this driver being reverse engineered, cx24120_init assigned ret on each call to writereg - they're not used for anything so remove them to clear up the codebase. Signed-off-by:

Remove __func__ from calls to dev_dbg as dynamic debug can add in the function name anyway. Remove debug call in dvbv3 read_signal_strength as userspace has this value anyway. Reword some strings to make them simpler / more obvious. Signed-off-by:

Previous version of this driver had a memset before every call to cmd. This meant the default value of cmd.arg[1] was zero unless burst is set. Make sure it remains zero. Also fe_sec_mini_cmd_t is an enum, so test against it. Signed-off-by:

Algorithm copied from cx24117.c - it seems to work. Showing 95% on a signal I know to be somewhere around 74dBuV. [mchehab@osg.samsung.net: merged two patches, to avoid breaking compilation] Signed-off-by:

This patch changes DVBv3 signal strength to read from the cache by moving the signal strength reading routine into get_stat, and reducing read_signal_strength to just returning the cached value. Signed-off-by:

get_frontend was making a call to read_status, which is being called periodically anyway. Have read_status store fe_status in the state struct instead and use that within get_frontend. Signed-off-by:

Change calculate_vco function to send_vco to tidy up cx24120_init function. xxyyzz variable is remnants of a manual div & remainder codepath to perform a u64 rounded div; replace with kernel macro DIV_ROUND_CLOSEST_ULL Hex values provided to the message are mainly variables calculated within this function, replace with these to remove hardcoding.

This patch adds in a missing command to cx24120_check_cmd. This part of the old reverse engineered driver was quite hard to follow - it's presumed the compiler did some neat optimisation that wasn't easy to decode. This command was checked for in that version but not copied across to the new switch statement. For reference, old reverse engineered code: xxzz = cmd->id - 0x11; // look for specific message id if ( xxzz <= 0x13 ) { msg_cmd_mask = 1 << xxzz; //0x0F8021 // if cmd_id 17 or 22 or 33-36, 42, 47, 57-61 etc. disable mpeg output if ( msg_cmd_mask & 0x0F8021 ) { // 000011111000000000100001b cx24120_msg_mpeg_output_global_config(state, 0); msleep(100); state->dvb_s2_mode &= 0xFD; // reset mpeg out enable flag } } Signed-off-by: -

This patch adds support for the Technisat Skystar S2 - this has been tried before but the cx24120 driver was a bit out of shape and it didn't got any further: https://patchwork.linuxtv.org/patch/10575/ It is an old card, but currently being sold off for next to nothing, so it's proving quite popular of late. Noticing it's quite similar to the cx24116 and cx24117 I've rewritten the driver in a similar way. There were a few registers and commands from those drivers missing from this one I've tested out and found they do something so they've been added in to speed up tuning and to make get_frontend return something useful.
