Hello,
This series re-enables the Faraday ftgmac100 controller driver and its Aspeed variant as as one can find on the OpenPOWER platforms. The driver is largely reworked to support the driver model and also adds the MDIO bus and phylib support. It was tested on the AST2500 evb.

Thanks,

Changes since v4 :
- introduced a wait_for_bit macro to handle timeouts when transmitting
Changes since v3 :
It didn't seem necessary to remove the 'dev' argument from the ftgmac100_phy_init() and ftgmac100_phy_reset() function prototypes as the code is completely reworked in patch 5.
- improved ftgmac100_mdio_init() and ftgmac100_phy_init() prototypes - introduced a ftgmac100_wait_for_txdone() function similar to the wait_for_bit_*() macros.
Changes since v2 :
- split changes in multiple patches to preserve git history, but the code has not changed since the reviewed v2 patchset. - included a couple more changes to sync the DTS file with Linux.
Changes since v1 :
- improved comments in the code - changed the type of 'iobase' to 'struct ftgmac100 *' to remove the casts in other routines. - replaced the loop in the mdio methods by a call to readl_poll_timeout() and fixed the returned value. - added a flush cache on the arrays of TX and RX descriptors in ftgmac100_start() - fixed returned value of - added a timer loop to catch transmit timeouts - introduced a clk_bulk - improved Kconfig description - introduced a udevice_id .data model - dropped is_aspeed bool - dropped MDIO interface setting for Aspeed SoC. The default is correct. - removed the clcoks which are now handled automatically in the ftgmac100 driver - introduced a fix for the D2-PLL clock setting
