+Tegra124 SoC EMC controller
+
+Required properties :
+- compatible : "nvidia,tegra124-emc".
+- reg : Should contain 1 or 2 entries:
+ - EMC register set
+ - MC register set : Required only if no node with
+ 'compatible = "nvidia,tegra124-mc"' exists. The MC register set
+ is first read from the MC node. If it doesn't exist, it is read
+ from this property.
+- timings : Should contain 1 entry for each supported clock rate.
+ Entries should be named "timing@n" where n is a 0-based increasing
+ number. The timings must be listed in rate-ascending order.
+
+Required properties for timings :
+- clock-frequency : Should contain the memory clock rate.
+- nvidia,parent-clock-frequency : Should contain the rate of the EMC
+ clock's parent clock.
+- clocks : Must contain an entry for each entry in clock-names.
+ See ../clocks/clock-bindings.txt for details.
+- clock-names : Must include the following entries:
+ - emc-parent : EMC's parent clock.
+- The following properties contain EMC timing characterization values:
+ - nvidia,emc-zcal-cnt-long
+ - nvidia,emc-auto-cal-interval
+ - nvidia,emc-ctt-term-ctrl
+ - nvidia,emc-cfg
+ - nvidia,emc-cfg-2
+ - nvidia,emc-sel-dpd-ctrl
+ - nvidia,emc-cfg-dig-dll
+ - nvidia,emc-bgbias-ctl0
+ - nvidia,emc-auto-cal-config
+ - nvidia,emc-auto-cal-config2
+ - nvidia,emc-auto-cal-config3
+ - nvidia,emc-mode-reset
+ - nvidia,emc-mode-1
+ - nvidia,emc-mode-2
+ - nvidia,emc-mode-4
+- nvidia,emc-burst-data : EMC timing characterization data written to
+ EMC registers.
+- nvidia,mc-burst-data : EMC timing characterization data written to
+ MC registers.
