Hello Joseph, Very nice to see that T210 will be able to get a non-alienated binding! I have some comments, please see them below. > Changes in v2: > * only use "tegra210" string in compatible string and remove the legacy > "tegra21" string. > * clock-frequency -> fix the unit from kilohertz to hertz > * add "interrupts" property > * s/nvidia,emc-min-mv/nvidia,emc-min-millivolt/ > * s/nvidia,gk20a-min-mv/nvidia,gk20a-min-millivolt/ > * s/nvidia,source/clock-names/ > * fix lots of properties that use underline to hyphen > * s/nvidia,emc-clock-latency-change/nvidia,emc-clock-latency-microsecond/ > * add more information in the property descriptions > --- > .../nvidia,tegra210-emc.txt | 614 ++++++++++++++++++ > 1 file changed, 614 insertions(+) > create mode 100644 Documentation/devicetree/bindings/memory-controllers/nvidia,tegra210-emc.txt > > diff --git a/Documentation/devicetree/bindings/memory-controllers/nvidia,tegra210-emc.txt b/Documentation/devicetree/bindings/memory-controllers/nvidia,tegra210-emc.txt > new file mode 100644 > index 000000000000..318239c3c295 > --- /dev/null > +++ b/Documentation/devicetree/bindings/memory-controllers/nvidia,tegra210-emc.txt > @@ -0,0 +1,614 @@ > +NVIDIA Tegra210 SoC EMC (external memory controller) > +==================================================== > + > +Required properties : > +- compatible : should be "nvidia,tegra210-emc". > +- reg : physical base address and length of the controller's registers. > +- clocks : phandles of the possible source clocks > +- clock-names : names of the possible source clocks > +- interrupts : Should contain the EMC general interrupt > +- #address-cells : should be 1 > +- #size-cells : should be 0 > +- nvidia,memory-controller : phandle of the memory controller. > +- nvidia,use-ram-code : boolean, indicates whether we should use RAM_CODE in > + the register to find matching emc-table nodes > + > +The node should contain a "emc-table" subnode for each supported RAM type > +(see field RAM_CODE in register APB_MISC_PP_STRAPPING_OPT_A), with its unit > +address being its RAM_CODE. > + > +Required properties for "emc-tables" nodes : > +- nvidia,ram-code : Should contain the value of RAM_CODE this timing set is > + used for. > + > +Each "emc-tables" node should contain a "emc-table" subnode for every supported > +EMC clock rate.

Is there any kind of electrical coupling in this case and thus this is a voltage regulators coupling? Is GPU-memory voltage dependency really could vary from board to board? It looks to me that at maximum the dependency could vary between SoC SKU variations and then this probably should be internal to the kernel. > +- nvidia,src-sel-reg : value of EMC CAR register to be used for this rate > +- nvidia,needs-training : 1 if needs training at boot, 0 otherwise > +- nvidia,trained : 1 if initial training has been done by firmware, 0 otherwise > +- nvidia,periodic-training : 1 if needs periodic training, 0 otherwise > +- nvidia,trained-dram-clktree-c0d0u0 : training data word > +- nvidia,trained-dram-clktree-c0d0u1 : training data word > +- nvidia,trained-dram-clktree-c0d1u0 : training data word > +- nvidia,trained-dram-clktree-c0d1u1 : training data word > +- nvidia,trained-dram-clktree-c1d0u0 : training data word > +- nvidia,trained-dram-clktree-c1d0u1 : training data word > +- nvidia,trained-dram-clktree-c1d1u0 : training data word > +- nvidia,trained-dram-clktree-c1d1u1 : training data word > +- nvidia,current-dram-clktree-c0d0u0 : training data word > +- nvidia,current-dram-clktree-c0d0u1 : training data word > +- nvidia,current-dram-clktree-c0d1u0 : training data word > +- nvidia,current-dram-clktree-c0d1u1 : training data word > +- nvidia,current-dram-clktree-c1d0u0 : training data word > +- nvidia,current-dram-clktree-c1d0u1 : training data word > +- nvidia,current-dram-clktree-c1d1u0 : training data word > +- nvidia,current-dram-clktree-c1d1u1 : training data word So the "clktree" properties describe the clock properties, hence should be in the clock-and-reset binding (clock's emc-timings table, see T124 for the example).
