| 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-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 after clock change |
| - 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 documentation: |
