The series adds Ethernet support for Poplar board. It firstly creates a reset driver for HiSilicon platform, then introduces higmacv300 Ethernet driver, and finally enables Ethernet support for Poplar board.
Changes for v3: - Add polarity support into reset driver, so that we can drop the hacking on gmac reset sequence from higmacv300 driver. Changes for v2: - Rename driver symbol to HIGMACV300_ETH. - Remove the use of temp variable 'addr' in higmac_recv(). - Simplify the return of function higmac_ofdata_to_platdata() and higmac_probe(). - Combine delaration and initialization for phyintf in function higmac_ofdata_to_platdata(). - Eliminate the MDIO read/write macros. - Use wait_for_bit_le32() for MDIO command completion polling. - Set up RX packet buffers in RX_FQ descriptor at initialization time, so that we do not need to allocate/free packet buffers repeatedly. - Inform GMAC that the RX descriptor is no longer in use in function higmac_free_pkt(). - Define BITS_DESC_ENA instead of using magic number 0xf.
