From bb78864a0c3c55461fc757c0c4b674f409518325 Mon Sep 17 00:00:00 2001 From: Alexander Aring Date: Mon, 14 Apr 2014 18:48:01 +0200 Subject: at86rf230: remove check if AVDD settled The AVDD regulator is only enabled when the RF section is active TX_ON (PLL_ON) state. Since commit 7dcbd22a97eb0689e6c583ad630ae0e7341e34c1 ("ieee802154: ensure that first RF212 state comes from TRX_OFF"). We are in TRX_OFF state at the time at86rf230_hw_init is run. Note that this test would only fail in case of a severe hardware malfunction (faulty/shorted power supply, etc.) so it wasn't all that useful in the first place.
