+NVIDIA Tegra124 SoC EMC (external memory controller)
+====================================================
+
+Required properties :
+- compatible : Should be "nvidia,tegra124-emc".
+- reg : physical base address and length of the controller's registers.
+- nvidia,memory-controller : phandle of the MC driver.
+
+The node should contain a "emc-timings" subnode for each supported RAM type (see field RAM_CODE in
+register PMC_STRAPPING_OPT_A), with its unit address being its RAM_CODE.
+
+Required properties for "emc-timings" nodes :
+- nvidia,ram-code : Should contain the value of RAM_CODE this timing set is used for.
+
+Each "emc-timings" node should contain a "timing" subnode for every supported EMC clock rate. The
+"timing" subnodes should have the clock rate in Hz as their unit address.
+
+Required properties for "timing" nodes :
+- clock-frequency : Should contain the memory clock rate in Hz.
+- The following properties contain EMC timing characterization values (specified in the board
+documentation) :
+  - nvidia,emc-auto-cal-config : EMC_AUTO_CAL_CONFIG
+  - nvidia,emc-auto-cal-config2 : EMC_AUTO_CAL_CONFIG2
+  - nvidia,emc-auto-cal-config3 : EMC_AUTO_CAL_CONFIG3
+  - nvidia,emc-auto-cal-interval : EMC_AUTO_CAL_INTERVAL
+  - nvidia,emc-bgbias-ctl0 : EMC_BGBIAS_CTL0
+  - nvidia,emc-cfg : EMC_CFG
+  - nvidia,emc-cfg-2 : EMC_CFG_2
+  - nvidia,emc-cfg-dig-dll : EMC_CFG_DIG_DLL
+  - nvidia,emc-ctt-term-ctrl : EMC_CTT_TERM_CTRL
+  - nvidia,emc-mode-1 : Mode Register 1
+  - nvidia,emc-mode-2 : Mode Register 2
+  - nvidia,emc-mode-4 : Mode Register 4
+  - nvidia,emc-mode-reset : Mode Register 0
+  - nvidia,emc-mrs-wait-cnt : EMC_MRS_WAIT_CNT
+  - nvidia,emc-sel-dpd-ctrl : EMC_SEL_DPD_CTRL
+  - nvidia,emc-xm2dqspadctrl2 : EMC_XM2DQSPADCTRL2
+  - nvidia,emc-zcal-cnt-long : EMC_ZCAL_WAIT_CNT
+  - nvidia,emc-zcal-interval : EMC_ZCAL_INTERVAL
+- nvidia,emc-configuration : EMC timing characterization data. These are the registers (see section
+"15.6.2 EMC Registers" in the TRM) whose values need to be specified, according to the board
