The gmac controller on sam9x7 has no internal pll to generate the 125MHz clock source for rgmii mode. This clock is generated on external board by eth-phy or clock oscillator. This change drops the tx_clk entry from gmac node. Signed-off-by: Mihai Sain <redacted> --- arch/arm/boot/dts/microchip/sam9x7.dtsi | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
