From e7c62552ec43c094ca523fc46b98181df364f49f Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Rafa=C5=82=20Mi=C5=82ecki?= Date: Sun, 19 Jun 2011 02:18:11 +0200 Subject: [PATCH] b43: HT-PHY: implement killing radio MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Closed drivers kill radio right after reading radio version and MACCTL, so it was easy to find related PHY ops: phy_read(0x0810) -> 0x0000 phy_write(0x0810) <- 0x0000 To find out the mask of above OP, MMIO hack was used to fake read val: phy_read(0x0810) -> 0xffff phy_write(0x0810) <- 0x0000 Signed-off-by: Rafał Miłecki Signed-off-by: John W.
