Re: [U-Boot] [U-Boot, v3, 05/20] net: gmac_rockchip: Add support for the RV1108 GMAC

The rv1108 GMAC only support rmii interface, so need to add the set_rmii() ops. Use the phy current interface to set rmii or rgmii ops. At the same time, need to set the mac clock rate of rmii with 50M, the clock rate of rgmii with 125M.

Signed-off-by: David Wu david.wu@rock-chips.com

Changes in v3:

• return error if there was no set_to_rgmii ops at rgmii case
• return error if there was no set_to_rmii ops at rmii case
• set and check clock rate when gmac clock is internal pll.

Changes in v2:

• Add check whether the set rgmii/rmii function is a valid function pointer
• Clean the grf offset at gmac_rockchip.c
• Use current phy interface to set mac clock rate
