Hi,
this patch series contains a cleanup patch which removes tabs after define.
Also this patch adds improvements to the calibration timeout handling.
At least we adding support for the easiest use case of slp_tr pin, which
indicate the TX_START command instead doing a state change over spi.
- Alex
changes since v2:
- Instead of declaring two variable in a single line, declare in two
separate lines.
- fix commit message in ("at86rf230: remove unnecessary tx state change"),
we doing a state change from ARET_ON into AACK_ON not ARET_ON.
