Hello,
this v6 mainly contains a rebase on latest linux-next.
There's an outstanding issue with frequencies lower than 102MHz, as the MC IP
complains of EMEM arbitration errors when at those frequencies. Any suggestions
welcome. The downstream kernels that I have seen ignore those errors, but mainline prints a message out, so it's actually visible even if everything else appears to keep working.
So far it has been tested only on a Jetson TK1.
Patch 1: Removes the old EMC clock, that was unused and not functional
Patch 2: Documents bindings for the new long-ram-code property
Patch 3: Adds API for reading the ram code
Patches 4 to 7: Document OF additions
Patch 8: Adds EMC node to Tegra124 DT
Patch 9: Adds timings for Jetson TK1 board
Patch 10: Adds functions to the MC driver so the EMC driver can stay within its
own registers
Patch 11: Adds the actual EMC driver, making use of the new MC API
Patch 12: Adds EMC clock driver, making use of API provided by the EMC driver
Patch 13: Adds debugfs entry for getting and setting the EMC rate
Patch 14: On Tegra124, have the EMC clock be the parent of the MC clock

Tomeu

This property contains a phandle to the EMC driver that is needed by the
EMC clock to request the EMC driver to do its part of the clock change
sequence.

This adds a new file, tegra124-jetson-tk1-emc.dtsi that contains
valid timings for the EMC memory clock. The file is included to the
main Jetson TK1 device tree.
The data is generated from the V5.0.17 version of the DVFS tables.

* Update data to V5.0.17 version of the DVFS tables
v4: * Rename timings subnode to emc-timings
* Remove unit addresses from timings and timing subnodes
v2: * Fix the unit addresses of the timings and timing nodes

I'm a little bit confused by this. On the one hand, some registers are
defined by dedicated DT properties, and on the other some are simply
specified in the nvidia,emc-configuration array. I guess the rationale
for this is to isolate the registers whose value may control the
driver vs. those that simply needs to be written as-is.
But in this case, why are some registers (like EMC_CFG_DIG_DLL)
present in both lists, sometimes with different values? In the case of
EMC_CFG_DIG_DLL, I also see that the read value of
"nvidia,emc-cfg-dig-dll" seems to never be used anywhere in
tegra124-emc.c. Should this property exist at all? Note that I have
only checked this one, there might be others in the same case.
Or maybe I completely misunderstood the intent here, in which case,
please enlighten me. :)

Well spotted! Looks like the nvidia,emc-cfg-dig-dll property should not
be there. The list was essentially copied from the downstream kernel;
looks like there the list of variables was probably based on that of
Tegra148, where the cfg-dig-dll seems to be used. (The downstream
Tegra124 does not use it.) Should check this for the other properties as
well.
