It would be readable if Required properties: - compatible : value should be one of the following:"atmel,sama5d3-hlcdc" - reg : base address and size of the HLCDC device registers. - clock-names : the name of the 3 clocks requested by the HLCDC device. Should contain "periph_clk", "sys_clk" and "slow_clk". - clocks : should contain the 3 clocks requested by the HLCDC device. ...... -- Regards, Varka Bhadram
