SM6FBQ / HackRF clone - History

USB: Bring in constants from host source code.

TODO: Deduplicate this when I'm not feeling so lazy.

USB: Make vendor request handler table read/write (not const).

SPI flash: check busy flag is clear BEFORE enabling writes

Merge pull request #571 from miek/fix-write-enable-hang

Fix hang in w25q80bv_write_enable

Fix hang in w25q80bv_write_enable

This line is meant to wait for the WEL bit to be set, to signify that
the WRITE_ENABLE command has finished.

The previous code didn't do any masking, so would hang if any other
status bits were set.

Fix communications failures on USB suspend. (#97)

Linux issues a `GET_STATUS` request to validate that a USB device has
correctly resumed after an idle suspend; but HackRF has thus far not
implemented `GET_STATUS`. As a result, Linux assumes our USB devices
are failing to resume, and winds up resetting them. Oops. ^-^

PortaPack: Remove noisy, extraneous "+" for amplifier gain labels, add space before "dB".

PortaPack: Improve baseband filter frequency label readability.

PortaPack: Update TX gain label.

Turns out the HackRF code refers to MAX2837 TX VGA gain, which is mis-labeled as a baseband setting. It's actually in the IF portion of the TX path.
