* net: asix: Fix ASIX 88772B with driver modelAlban Bedel2016-09-27-24/+3
| | | | | | | | | | | | | | | | | | | Commit 147271209a9d ("net: asix: fix operation without eeprom") added a special handling for ASIX 88772B that enable another type of header. This break the driver in DM mode as the extra handling needed in the receive path is missing. However this new header mode is not required and only seems to increase the code complexity, so this patch revert this part of commit 147271209a9d. This also reverts commit 41d1258aceb45b45f9e68f67a9c40f0afbc09dc9 ("net: asix: Fix AX88772B when used with DriverModel") of late.

* net: asix: Fix AX88772B when used with DriverModelJoshua Scott2016-09-09-0/+5
| | | | | | | | | | | | | | | | | | | A previous patch (net: asix: fix operation without eeprom) added a two-byte shift to the packet buffer when receiving a packet on the AX88772B. This shift was not included when the driver was updated to work with DriverModel. Testing on a Marvell DB-88F6820-ACM showed that the adapter was not functioning correctly (EHCI timeouts). This patch brings the two-byte shift to the DriverModel implementation of ops->recv (asix_eth_recv). Testing on the same board, we were able to TFTP a file over and confirm that the crc32 was correct.

| | | | | | | | This USB Ethernet driver is quite widely use. Allow it to work with CONFIG_DM_ETH enabled. Most of the code remains common but there is a new packet receive flow which is handled specially. Signed-off-by: Simon Glass <sjg@chromium.org>
* net: cosmetic: Fix var naming net <-> eth driversJoe Hershberger2015-04-18-1/+2
| | | | | | | | | | | | | | | Update the naming convention used in the network stack functions and variables that Ethernet drivers use to interact with it. This cleans up the temporary hacks that were added to this interface along with the DM support. This patch has a few remaining checkpatch.pl failures that would be out of the scope of this patch to fix (drivers that are in gross violation of checkpatch.pl).

* net: asix: don't pad odd-length TX packetsStephen Warren2014-03-07-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | For Ethernet/USB RX packets, the ASIX HW pads odd-sized packets so that they have an even size. Currently, asix_recv() does remove this padding, and asic_send() adds equivalent padding in the TX path. However, the HW does not appear to need this packing for TX packets in practical testing with "ASIX Elec. Corp. AX88x72A 000001" Vendor: 0x0b95 Product 0x7720 Version 0.1. The Linux kernel does no such padding for the TX path. Remove the padding from the TX path: * For consistency with the Linux kernel. * NVIDIA has a Tegra simulator which validates that the length of USB packets sent to an ASIX device matches the packet length value inside the packet data. Having U-Boot and the kernel do the same thing when creating the TX packets simplifies the simulator's validation.

* usb: asix: Move software resets to basic_initJulius Werner2013-06-12-23/+17
| | | | | | | | | | | | | | | | | | | | | | | | The ASIX driver calls a basic_init() function during get_info(), so that not all initialization tasks need to be redone on every init(). Unfortunately, the most important one is still triggered too often: the driver does a full port and MII reset on every asix_init(), requiring up to several seconds to reestablish the link. This patch confines that software reset into the asix_basic_init() function so that it will only be executed once. This saves about a second of boot time on systems using BOOTP. Note: this patch was previously submitted many moons ago as: usb: usbeth: asix: Do a fast init if link already established That patch seens to have been lost or forgotten, so this is a rebased version. It is tested on snow with a Asix USB dongle (Cisco).

* net: asix: add AX88772B supportLucas Stach2012-09-26-12/+23
| | | | | | | | | | | | | | | | | | | | Add AX88772B ID together with two fixes needed to make this work. 1. The packet length check has to be adjusted, as all ASIX chips only use 11 bits to indicate the length. AX88772B uses the other bits to indicate unrelated things, which cause the check to fail. This fix is based on a fix for the Linux kernel by Marek Vasut. Linux upstream commit: bca0beb9363f8487ac902931a50eb00180a2d14a 2. AX88772B provides several bulk endpoints. Only the first IN/OUT endpoints work in the default configuration. So stop enumeration after we found them to avoid overwriting the endpoint config with a non-working one.

| | | | | | | | | | | | | | Initial device MAC should be read while getting info about the device, so it's wrong to only read it in asix_init().
