ROG means ASUS "Republic of Gamers" laptops. The input device info
also represents itself as "ASASTeK COMPUTER INC. ROG MacroKey". It
uses special HID_USAGE code for function keys. This commit remap the
special code to standard keycode for function keys handling. It's
verified on GL553VD/VE, GL753VD/VE.

Hi Chris,

there is no real point of having a separate driver from hid-asus. The
HID tree prefer to group drivers by vendors, so these keyboards should
be supported through hid-asus.

Please fold the patch in hid-asus and probably add a special quirk for
these keyboards in input_mapping. With a little luck, the quirk won't
even be required and we can apply these mapping to all Asus keyboards.

Not sure this belongs here. You are checking this in a local driver, not
in the generic hid-input path, so there is no point in telling everybody
that ASUS ROG keyboards are using this usage page.

Cheers,
Benjamin

In addition to what Benjamin said already, you also seem to be missing 
hid_have_special_driver[] entry for these VID/PIDs

You're right. I forgot to add VID/PID in hid_have_special_driver in
this patch. I'll modify per Benjamin's suggestion and re-commit.

Thanks for the feedback. We will submit a new version soon.

Just to confirm, hid-asus currently depends on I2C_HID. The new
devices being quirked now are USB devices. With this patch should we
now update it to depend on I2C_HID && USB_HID?

Actually you can remove the I2C_HID dependency entirely (and not add one
for USB_HID). In the Kconfig, the modules are already guarded by a
"if HID", and there is nothing transport specific in hid-asus as far as
I can tell.

Note: we should also probably clean up the Kconfig once again and remove
all the "depends on HID" for those that are guarded by the if statement.

Cheers,
Benjamin
