From 9b2777d6089bcd7fb035847f907280560fe233c8 Mon Sep 17 00:00:00 2001 From: Phoebe Buckheister Date: Mon, 17 Feb 2014 11:34:08 +0100 Subject: ieee802154: add TX power control to wpan_phy Replace the current u8 transmit_power in wpan_phy with s8 transmit_power. The u8 field contained the actual tx power and a tolerance field, which no physical radio every used. Adjust sysfs entries to keep compatibility with userspace, give tolerances of +-1dB statically there. This patch only adds support for this in the at86rf230 driver and the RF212 chip. Configuration calculation for RF212 is also somewhat basic, but does the job - the RF212 datasheet gives a large table with suggested values for combinations of TX power and page/channel, if this does not work well, we might have to copy the whole table.
