2017-04-04net: gmac_rockchip: Add support for the RK3399 GMACPhilipp Tomsich
The GMAC in the RK3399 is very similar to the RK3288 variant (i.e. it is a Designware GMAC core and requires similar configuration as the RK3288 to switch it to RGMII and set up the TX/RX delays for Gigabit). The key difference is that the register offsets (within the GRF block) and bit-offsets (within those registers) used to hold the configuration differ between the various RK32/33 CPUs. This change refactors the gmac_rockchip.c driver to use a function table (selected via driver_data) to factor out these differences. Each function's implementation then matches the underlying processor. Some collateral changes are needed in the definitions describing the bits and offsets in the GRF are needed to prefix each set of symbolic constants with the SoC name to avoid name clashes... and in doing so, the shifts for masks and constants have been moved into the header files for readability (and to make it easier to stay below 80 chars).

2017-02-08dm: core: Replace of_offset with accessorSimon Glass
At present devices use a simple integer offset to record the device tree node associated with the device. In preparation for supporting a live device tree, which uses a node pointer instead, refactor existing code to access this field through an inline function.

2017-01-11net: gmac_rockchip: Add Rockchip GMAC driverSjoerd Simons
Add a new driver for the GMAC ethernet interface present in Rockchip RK3288 SOCs. This driver subclasses the generic design-ware driver to add the glue needed specifically for Rockchip.
