From 79d7f4bcf8519abbea46d909ff01a1358b431e1d Mon Sep 17 00:00:00 2001 From: Sujith Date: Tue, 1 Jun 2010 15:14:06 +0530 Subject: ath9k_hw: Optimize ath9k_hw_ar9287_set_board_values Rather than doing a series of RMWs, calculate the value to be written to the register in question and do a single REGWRITE. This improves bringup time. This depends on the analog_shiftreg configuration option, which is currently buggy. For AP mode, a delay of 100us has to be the default. For station mode, this knob has to be enabled on a per-case basis, though it is a little unclear on when to enable a delay. This can be fixed later though.
