For imx6sx, it alos is the clock source of interrupt coalescing. The clock range: 200Mhz ~ 266Mhz. clk_ref: refrence clock for tx and rx. For imx6sx enet RGMII mode, the refrence clock is 125Mhz coming from internal PLL or external. In i.MX6sx-arm2 board, the clock is from internal PLL. clk_ref is optional, depends on board. clk_enet_out: The clock can be output from internal PLL. It can supply 50Mhz clock for phy. clk_enet_out is optional, depends on chip and board. clk_ptp: 1588 ts clock. It is optional, depends on chip. The patch add clk_ref to distiguish the different clocks. Signed-off-by: Fugang Duan Signed-off-by: Frank Li Signed-off-by: David S. Miller --- Reading git-diff-tree failed
