We are looking into adding some additional keycodes to add support for
radar control. In total we are adding 29 keycodes which seems to
exceed the KEY_MAX limit set, so we have also bumped this value to
0x3ff to double the available keycodes.

No, we will not be adding these new keys since I do not see any users of
the previously defined ones anywhere, not in kernel sources and not in
the HID specification.

You seem to be creating a purpose-built devices where you control your
userspace, and I do not think the new keycodes will be of any use to
anyone but your specific application. You are also unlikely to be
running anything else besides the software that you are developing on
these devices, so I'd recommend simply reuse parts of the existing key
code space for your purposes (KEY_MACRO*, BTN_TRIGGER_HAPPY*, etc).

Thanks.
