Merge branch 'gmac-next' 



Roger Chen says:

====================
support GMAC driver for RK3288

Roger Chen (6):
  patch1: add driver for Rockchip RK3288 SoCs integrated GMAC
  patch2: define clock ID used for GMAC
  patch3: modify CRU config for Rockchip RK3288 SoCs integrated GMAC
  patch4: dts: rockchip: add gmac info for rk3288
  patch5: dts: rockchip: enable gmac on RK3288 evb board
  patch6: add document for Rockchip RK3288 GMAC

Tested on rk3288 evb board:
Execute the following command to enable ethernet,
set local IP and ping a remote host.

busybox ifconfig eth0 up
busybox ifconfig eth0 192.168.1.111
ping 192.168.1.1

Rockchip SoC RK3288 10/100/1000 Ethernet driver(GMAC)



The device node has following properties.



Required properties:

 - compatible: Can be "rockchip,rk3288-gmac".

 - reg: addresses and length of the register sets for the device.

 - interrupts: Should contain the GMAC interrupts.

 - interrupt-names: Should contain the interrupt names "macirq".

 - rockchip,grf: phandle to the syscon grf used to control speed and mode.

 - clocks: <&cru SCLK_MAC>: clock selector for main clock, from PLL or PHY.

	   <&cru SCLK_MAC_PLL>: PLL clock for SCLK_MAC

	   <&cru SCLK_MAC_RX>: clock gate for RX

	   <&cru SCLK_MAC_TX>: clock gate for TX

	   <&cru SCLK_MACREF>: clock gate for RMII referce clock

	   <&cru SCLK_MACREF_OUT> clock gate for RMII reference clock output

	   <&cru ACLK_GMAC>: AXI clock gate for GMAC

	   <&cru PCLK_GMAC>: APB clock gate for GMAC

 - clock-names: One name for each entry in the clocks property.

 - phy-mode: See ethernet.txt file in the same directory.

 - pinctrl-names: Names corresponding to the numbered pinctrl states.

 - pinctrl-0: pin-control mode. can be <&rgmii_pins> or <&rmii_pins>.

 - clock_in_out: For RGMII, it must be "input", means main clock(125MHz)

   is not sourced from SoC's PLL, but input from PHY; For RMII, "input" means

   PHY provides the reference clock(50MHz), "output" means GMAC provides the

   reference clock.

 - snps,reset-gpio       gpio number for phy reset.

 - snps,reset-active-low boolean flag to indicate if phy reset is active low.

 - assigned-clocks: main clock, should be <&cru SCLK_MAC>;

 - assigned-clock-parents = parent of main clock.

   can be <&ext_gmac> or <&cru SCLK_MAC_PLL>.



Optional properties:

 - tx_delay: Delay value for TXD timing. Range value is 0~0x7F, 0x30 as default.

 - rx_delay: Delay value for RXD timing. Range value is 0~0x7F, 0x10 as default.
