[PATCH v3 0/2] NFC: trf7970a: Add option to reduce antenna gain

[Paul Geurts]

The TRF7970a device is sensitive to RF disturbances, which can make it
hard to pass some EMC immunity tests. By reducing the RX antenna gain,
the device becomes less sensitive to EMC disturbances, as a trade-off
against antenna performance.
