Now that most functionality were merged at the driver,
update its TODO list, and add a "TODO" comment for the two
WMI API commands that are currently not implemented.
In summary:
- on Rev 0.64, command 0x07 (LED_NOTIFICATION) is meant to store
all config settings at EEPROM. That doesn't seem to be needed
on Skull Canyon, but tests with different hardware would be
nice in order to double-check it. Also, maybe Rev 1.00 would
make it mandatory;
- Rev 1.00 added command 0x08 to switch the LED type
(LED_SWITCH_TYPE at the driver's nomenclature) between
single color LED and multi color LED). Not sure how this
should be properly implemented (if this is the case);
- The tests for NUC6 version were using a Skull Canyon NUC.
It allowed to check that the driver's logic runs, but
it is not enough to see if everything is really working.
Tests on NUC6 or NUC7 are required;
- On a suspend test, I noticed that some controls were reset
to the default at resume time. It is required to check
what's happening there and address it properly.
- Need to validate the uAPI and document it before moving
this driver out of staging.
