2020-05-05staging: vt6656: refactor power save operationMalcolm Priestley
At present the power save wake uses the listening interval and the slow path to wake up. The following using a beacon interval of 100 and listen interval of 5. The TBTT set at 100 wake-up sequence; 100 TBTT wake-up set to listen interval. 200 TBTT 300 TBTT 400 TBTT --> call vnt_next_tbtt_wakeup on slow path Beacon heard and passed through at the approx 500 interval. 500 TBTT 600 TBTT wake-up set to listen interval The TBTT set at 500 wake-up sequence and always listen flagged on; 100 No TBTT 200 No TBTT 300 No TBTT 400 No TBTT 500 TBTT - beacon heard and passed through 600 No TBTT A further enhancement because the TBTT is more precise the dtim_period can be used instead. When Power save is off the TBTT continues to run at the listen interval but all the other beacons are passed. The code in vnt_int_process_data is no longer required.

2020-04-28staging: vt6656: Remove functions' documentationOscar Carter
Remove the functions' documentation as the names of the functions are clear enought. Also, the actual documentation it's not correct in all cases.

2020-04-28staging: vt6656: Check the return value of vnt_control_out_* callsOscar Carter
Check the return value of vnt_control_out_* function calls. When necessary modify the function prototype to be able to return the new checked error code. It's safe to modify all the function prototypes without fix the call because the only change is the return value from void to int. If before the call didn't check the return value, now neither.

2017-11-28staging: vt6656: Remove redundant license textGreg Kroah-Hartman
Now that the SPDX tag is in all vt6656 files, that identifies the license in a specific and legally-defined manner. So the extra GPL text wording can be removed as it is no longer needed at all. This is done on a quest to remove the 700+ different ways that files in the kernel describe the GPL license text. And there's unneeded stuff like the address (sometimes incorrect) for the FSF which is never needed. No copyright headers or other non-license-description text was removed.

2017-11-28staging: vt6656: add SPDX identifiers to all vt6656 driver filesGreg Kroah-Hartman
It's good to have SPDX identifiers in all files to make it easier to audit the kernel tree for correct licenses. Update the vt6656 driver files with the correct SPDX license identifier based on the license text in the file itself. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This work is based on a script and data from Thomas Gleixner, Philippe Ombredanne, and Kate Stewart.

2015-09-29staging: vt6656: implement power saving code.Malcolm Priestley
The device should ready to listen to next beacon so on count down of wake_up_count == 1. schedule command WLAN_CMD_TBTT_WAKEUP which calls vnt_next_tbtt_wakeup which wakes the device. This restores this back to vendors code with a slight difference the count down is in the interrupt handler.
