5 - compatible : Should be "nvidia,tegra124-emc".
6 - reg : physical base address and length of the controller's registers.
7 - nvidia,memory-controller : phandle of the MC driver.
9 The node should contain a "emc-timings" subnode for each supported RAM type
13 Required properties for "emc-timings" nodes :
14 - nvidia,ram-code : Should contain the value of RAM_CODE this timing set is
17 Each "emc-timings" node should contain a "timing" subnode for every supported
18 EMC clock rate. The "timing" subnodes should have the clock rate in Hz as
22 - clock-frequency : Should contain the memory clock rate in Hz.
