| | | | | | | | | | | priv->buswidth expects IORESOURCE_MEM_* macros which are not identical to the integer byte bus width, so calling dm9000_setup_buswidth() for the platform_data case is wrong. fixes: d818f02 net: dm9k: add device tree support Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Reported by: 张忠山 <zzs213@126.com>

* driver: replace dev_request_mem_region with dev_request_mem_resourceSascha Hauer2016-03-071-6/+9

* net: dm9k: fix reset routineAntony Pavlov2015-05-121-2/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Based on Linux's commit: commit 09ee9f87d02e779e4fc3f5c29212c733d6d6e349 Author: Michael Abbott <michael.abbott@diamond.ac.uk> Date: Wed Oct 16 11:41:33 2013 +0300 dm9000: Implement full reset of DM9000 network device A Davicom application note for the DM9000 network device recommends performing software reset twice to correctly initialise the device. Without this reset some devices fail to initialise correctly on system startup. N.B. DM9000B on MIPS Creator CI20 board needs additional workaround (see the 'Make all GPIO pins outputs' and 'Power internal PHY' lines). This workaround was taken from this U-boot's commit: commit fbcb7ece0ea1e364180f1cf963e0fa0ce7f6560d Author: Remy Bohmer <linux@bohmer.net> Date: Tue Jun 3 15:26:24 2008 +0200 DM9000: Improve eth_reset() routine According to the application notes of the DM9000 v1.22 chapter 5.2 bullet 2, the reset procedure must be done twice to properly reset the DM9000 by means of software. This errata is not needed anymore for the DM9000A, but it does not bother it. This change has been tested with DM9000A, DM9000E, DM9000EP.

* Add support for more recent Davicom DM9k devicesJuergen Beisert2011-12-141-0/+797
This patch adds support for the more recent DM9000A and DM9000B types, and keeps support for the older DM9000E device. As this patch is more or less a complete re-wrote of the existing driver I add a new source file instead of fixing the existing one. In a later patch the old driver will be removed.
