Embedded Memory Controller
Properties:
- name : Should be emc
- #address-cells : Should be 1
- #size-cells : Should be 0
- compatible : Should contain "nvidia,tegra20-emc".
- reg : Offset and length of the register set for the device
- nvidia,use-ram-code : If present, the sub-nodes will be addressed
and chosen using the ramcode board selector. If omitted, only one
set of tables can be present and said tables will be used
irrespective of ram-code configuration.
Child device nodes describe the memory settings for different configurations and clock rates.
Example:
emc@7000f400 {
#address-cells = < 1 >;
#size-cells = < 0 >;
compatible = "nvidia,tegra20-emc";
reg = <0x7000f4000 0x200>;
}
Embedded Memory Controller ram-code table
If the emc node has the nvidia,use-ram-code property present, then the
next level of nodes below the emc table are used to specify which settings
apply for which ram-code settings.
If the emc node lacks the nvidia,use-ram-code property, this level is omitted
and the tables are stored directly under the emc node (see below).
Properties:
- name : Should be emc-tables
- nvidia,ram-code : the binary representation of the ram-code board strappings
for which this node (and children) are valid.
Embedded Memory Controller configuration table
This is a table containing the EMC register settings for the various
operating speeds of the memory controller. They are always located as
subnodes of the emc controller node.
There are two ways of specifying which tables to use:
* The simplest is if there is just one set of tables in the device tree,
and they will always be used (based on which frequency is used).
This is the preferred method, especially when firmware can fill in
this information based on the specific system information and just
pass it on to the kernel.
* The slightly more complex one is when more than one memory configuration
might exist on the system. The Tegra20 platform handles this during
early boot by selecting one out of possible 4 memory settings based
on a 2-pin "ram code" bootstrap setting on the board. The values of
these strappings can be read through a register in the SoC, and thus
used to select which tables to use.
Properties:
- name : Should be emc-table
- compatible : Should contain "nvidia,tegra20-emc-table".
- reg : either an opaque enumerator to tell different tables apart, or
the valid frequency for which the table should be used (in kHz).
- clock-frequency : the clock frequency for the EMC at which this
table should be used (in kHz).
- nvidia,emc-registers : a 46 word array of EMC registers to be programmed
for operation at the 'clock-frequency' setting.
The order and contents of the registers are:
RC, RFC, RAS, RP, R2W, W2R, R2P, W2P, RD_RCD, WR_RCD, RRD, REXT,
WDV, QUSE, QRST, QSAFE, RDV, REFRESH, BURST_REFRESH_NUM, PDEX2WR,

NVIDIA Tegra Power Management Controller (PMC)
Properties:
- name : Should be pmc
- compatible : Should contain "nvidia,tegra<chip>-pmc".
- reg : Offset and length of the register set for the device
- nvidia,invert-interrupt : If present, inverts the PMU interrupt signal.
The PMU is an external Power Management Unit, whose interrupt output
signal is fed into the PMC. This signal is optionally inverted, and then
fed into the ARM GIC. The PMC is not involved in the detection or
handling of this interrupt signal, merely its inversion.
Example:
pmc@7000f400 {
compatible = "nvidia,tegra20-pmc";
reg = <0x7000e400 0x400>;
nvidia,invert-interrupt;
};
