dt-bindings: memory-controller: Convert Tegra124 EMC to json-schema
Convert the device tree bindings for the Tegra124 EMC controller to the DT schema format using json-schema. While at it, clean up the binding a little bit by removing any mention of how RAM code and clock frequency are represented in unit-addresses (which they aren't) and by adding the EMC clock without which the EMC controller can't change the frequency at which the external memory is clocked. While this is technically an ABI break (the clock was not required before), this should be fine because there isn't much that the EMC driver can do without access to the EMC clock.

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:
