From 714fa6636331d33c6045efe394f36c964a6c14ee Mon Sep 17 00:00:00 2001 From: Gertjan van Wingerde Date: Sat, 13 Feb 2010 20:55:48 +0100 Subject: rt2x00: Reorganize RT chipset setting for PCI/SOC devices. Don't set the RT chipset for a device from within the generic PCI/SOC code, but rather from the individual drivers, so that individual drivers have more control over what RT chipset is set. Preparation for chip handling updates for rt2800 devices. Signed-off-by: Gertjan van Wingerde Acked-by: Ivo van Doorn Signed-off-by: John W.

The recent rt2800 devices are no longer really identified by their PCI ID's, but rather by the contents of their CSR0 register. Also for the other chipsets is the contents of this CSR0 register important. Change the chipset determination logic to be more aligned with the rt2800 model. Preparation for the support of rt3070 / rt3090 based devices. Signed-off-by: Gertjan van Wingerde Acked-by: Ivo van Doorn Signed-off-by: John W.
