The 1.2V supply for CSI and DSI was previously marked always-on. This is
suboptimal because it prevents the supply from being disabled when there
is no activity in the display or capture paths that it powers.
Hook up the regulator to the DSI output and mark it as not always-on, so
that it will only be enabled when DSI actually needs it.

A large part of the arm-soc patches are nowadays DT changes, adding support
for new SoCs, boards and devices without changing kernel source. The plan
is still to move the devicetree files out of the kernel tree and reduce
the amount of churn going on here, but we keep finding reasons to delay
doing that.
Changes are really all over the place, with little sticking out particularly.
We have contributions from a total of 116 people in this branch.
Unfortunately, the size of this branch also causes a significant number
of conflicts at the moment, typically when subsystem maintainers merge
patches that change the driver at the same time as the dts files. In
most cases this could be avoided because the dts changes are supposed
to be compatible in both ways, and we are asking everyone to send ARM
dts changes through our tree only.

Neither Tegra114 nor Tegra124 allow "low power mode" to be configured
on SDIO1 or SDIO3 drive groups. Remove the attempt to configure that
option from the Dalmore and Venice2 DTs.
The Venice2 DT contained duplicate configurations for most sdmmc1_*
pins. Remove the duplicate pins from one of the nodes, and fix the
configuration since the remaining clk pin is output-only.

DT node names should include a unit address iff the node has a reg

rule, namely that node names only needed to include a unit address if it
was required to make the node name unique. Consequently, many unit
addresses are missing. Add them.

Replace /include/ (dtc) with #include (C pre-processor) for all Tegra DT
files, so that gcc -E handles the entire include tree, and hence any of
those files can #include some other file e.g. for constant definitions.
This allows future use of #defines and header files in order to define
names for various constants, such as the IDs and flags in GPIO
specifiers. Use of those features will increase the readability of the

Set "regulator-always-on" for the SD slot on Dalmore, so that SD cards
work. This used to work, since this regulator is on by default, but was
broken by commit "ARM: tegra: dalmore: add TPS65090 node", since that
didn't specify always-on for this regulator.
In the long run, the regulators should all be hooked up to the SDHCI
device nodes. However, we haven't done that for any of the Tegra boards
yet, so to be consistent, this patch simply forces the regulator on,
rather than hooking it up and making it work differently to other boards.
