This is the version 6 submission for the Altera Triple Speed Ethernet (TSE) driver. All comments received during the version 2, 3, 4, and 5 submissions have been accepted. Please find the change log and a description of the submission below. If you find the submission acceptable, please consider this patch set for inclusion into the Linux kernel. Thank you, Vince V6: Address comments from V5 review - add call to skb_tx_timestamp in the drivers transmit path - correct use of unsigned int where it was cast to pointer. Use types appropriate for intended and correct use to let the compiler warn us when type usage is incorrect. - use correct semantics for pointer arithmetic in same code path V5: Address comments from V4 review - Add descriptions of statistics to driver documentation. The statstics supported by the driver/controller map to IEEE and RFC statistics, and the names and mappings are described in the user documentation. - Change "unsigned int" to u32 in device structure definitions - Change used of netdev_warn to netif_warn in altera_sgdma.c - Change stat name rx_fifo_drops to ether_drops to match the event actually counted by the hardware. V4: Address comments from V3 review - Change statistics names in ethtool module to follow common use in other ethernet drivers. - remove an unnecessary case in ethtool module - change logging to use netdev_* where possible instead of dev_* - remove logging for OOM errors since those are already logged V3: Address comments from V2 review - Reorder patch submission so that net/ethernet Makefile and Kconfig are committed last, thus not breaking bisect - Use of_get_mac_address instead of of_get_property - Change supplemental and hash configuration bindings to boolean/empty, and more meaningful names - Add check for failure from calls to of_phy_connect and connect_local_phy - Correct code to find mdio child node - Update bindings document - Remove cast to u64 when not necessary - add use of const for statistics strings V2: Address comments from initial RFC review. - The driver files were broken up by major sections of functionality. These include MSGDMA, SGDMA, Misc, and Main. - Add patch for MAINTAINERS file, add the maintainer for this submission - Use 32-bit lower/upper physical address accessor functions so the driver is 64-bit ready. - Use standard bindings where applicable. Especially phy-addr, and change "altr,rx-fifo-depth" to "rx-fifo-depth" and "altr,tx-fifo-depth" to "tx-fifo-depth". - Add use of max-frame-size property - Update bindings documents accordingly - Correct interrupt handler to use budget parameter in the convential way - Use macros consistently to define bit fields across files - Correct include exclusion macro in altera_msgdmahw.h (typo) - Remove use of barriers, these were not necessary since the DMA APIs ensure memory & buffer consistency - Remove use of netif_carrier_off in driver - move probing of phy from the open function to the probe function - use of_get_phy_mode instead of custom function - Use the .data field in the device structure to obtain a pointer to SGDMA or MSGDMA device specific properties and functions. - remove custom function to access devicetree since Altera specific bindings requiring it's use have been deprecated in favor of standard bindings. The Altera TSE is a 10/100/1000 Mbps Ethernet soft IP component that can be configured and synthesized using Quartus, and programmed into Altera FPGAs. Two types of soft DMA IP components are supported by this driver - the Altera SGDMA and the MSGDMA. The MSGDMA DMA component is preferred over the SGDMA, since the SGDMA will be deprecated in favor of the MSGDMA. Software supporting both is provided for customers still using the SGDMA and to demonstrate how multiple types of DMA engines may be supported by the TSE driver in the event customers wish to develop their own custom soft DMA engine for particular applications. The design has been tested on Altera's Cyclone 4, 5, and Cyclone 5 SOC development kits using an ARM A9 processor and an Altera NIOS2 processor. Differences in CPU/DMA coherency management and address alignment are addressed by proper use of driver APIs and semantics.
