net: Add TI DaVinci EMAC driver Add support for TI DaVinci EMAC driver. TI DaVinci Ethernet Media Access Controller module is based upon TI CPPI 3.0 DMA engine and supports 10/100 Mbps on all and Gigabit modes on some TI devices. It supports MII/RMII and has up to 8Kbytes of internal descriptor memory. This driver has been working on several TI devices including DM644x, DM646x and DA830 platforms.

TI Davinci EMAC : Re-use driver for other platforms. The davinci EMAC peripheral is also available on other TI platforms -notably TI AM3517 SoC. This patch modifies the config option and the platform structure header files so that the driver can be reused on non-davinci platforms as well.

TI DaVinci EMAC: Clear statistics register properly. The mechanism to clear the statistics register is dependent on the status of GMIIEN bit in MAC control register. If the GMIIEN bit is set, the stats registers are write to decrement. If the GMIIEN bit is cleared, the stats registers are plain read/write registers. The stats register clearing operation must take into account the current state of GMIIEN as it can be cleared when the interface is brought down. With existing implementation logic, querying for interface stats when the interface is down, can corrupt the statistics counters. This patch examines the GMIIEN bit status in MAC_CONTROL register before choosing an appropriate mask for clearing stats registers.

TI DaVinci EMAC: Clear statistics register properly. The mechanism to clear the statistics register is dependent on the status of GMIIEN bit in MAC control register. If the GMIIEN bit is set, the stats registers are write to decrement. If the GMIIEN bit is cleared, the stats registers are plain read/write registers. The stats register clearing operation must take into account the current state of GMIIEN as it can be cleared when the interface is brought down. With existing implementation logic, querying for interface stats when the interface is down, can corrupt the statistics counters. This patch examines the GMIIEN bit status in MAC_CONTROL register before choosing an appropriate mask for clearing stats registers.

TI DaVinci EMAC: Handle emac module clock correctly. In the driver probe function the emac module clock needs to be enabled before calling register_netdev(). As soon as the device is registered the driver get_stats function can be invoked by the core - the module clock must be switched on to be able to read from stats registers. Also explicitly call matching clk_disable for failure conditions in probe function. Signed-off-by: Sriramakrishnan <srk@ti.com> Signed-off-by: David S. Miller <davem@davemloft.net>

TI DaVinci EMAC: delay DaVinci EMAC initialization On TI's DA850/OMAP-L138 EVM, MAC address is stored in SPI flash which is accessed using MTD interface. This patch delays the initialization of DaVinci EMAC driver by changing module_init to late_initcall. This helps SPI and MTD drivers to get initialized before EMAC thereby enabling EMAC driver to read the MAC address while booting and use it. Tested with NFS on DM644x, DM6467, DA830/OMAP-L137 and DA850/OMAP-L138 EVMs. Signed-off-by: Sudhakar Rajashekhara <sudhakar.raj@ti.com> Reviewed-by: Chaithrika U S <chaithrika@ti.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com> Signed-off-by: David S.
