Olof Johansson c4574aa00e ARM: dts: tegra: move serial aliases to per-board
There are general changes pending to make the /aliases/serial* entries
number the serial ports on the system. On Tegra, so far the ports have
been just numbered dynamically as they are configured so that makes them
change.

To avoid this, add specific aliases per board to keep the old numbers.
This allows us to change the numbering by default on future SoCs while
keeping the numbering on existing boards.

Thierry Reding 87ab35330c ARM: tegra: dalmore - Add DSI power supply
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.

Linus Torvalds f83ccb9358 ARM: SoC: device tree changes
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

option from the Dalmore and Venice2 DTs.

pins. Remove the duplicate pins from one of the nodes, and fix the
configuration since the remaining clk pin is output-only.

Set "regulator-always-on" for the SD slot on Dalmore, so that SD cards

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.
