I applied this without the pmic changes. I am not convinced about those.
The tps node is already being referred to as phandle. I am not sure
referring to each individual regulator using phandle is needed. Other
files like am335x-evm.dts don't do it as well.
Another thing is whether we really need the tp6507x.dtsi file. It does
not seem to contain much and also da850-evm.dts is the only file
including it. So it seems pretty pointless to me.
Here is what I committed.
Thanks,
Sekhar

ARM: dts: da850-evm: use phandles to extend nodes
Many node labels in the device tree (like serial0, serial1, etc) are being
redefined, so let's modernize the device tree by using phandles to
extend the existing nodes. This helps reduce the whitespace.

I applied this without the pmic changes. I am not convinced about those.
The tps node is already being referred to as phandle. I am not sure
referring to each individual regulator using phandle is needed. Other
files like am335x-evm.dts don't do it as well.
Another thing is whether we really need the tp6507x.dtsi file. It does
not seem to contain much and also da850-evm.dts is the only file
including it. So it seems pretty pointless to me.
Here is what I committed.
Thanks,
Sekhar

ARM: dts: da850-evm: use phandles to extend nodes
Many node labels in the device tree (like serial0, serial1, etc) are being
redefined, so let's modernize the device tree by using phandles to
extend the existing nodes. This helps reduce the whitespace.

I tested the regulator values and names after booting to see if the
names and values matched the expected values. They did, so I am
fairly confident it would have worked.

Do you want me to do a patch that removes the tp6507x.dtsi file and
just sets up the
PMIC from scratch within the da850-evm file?

Thank you. I think looks cleaner this way, and more consistent with
many of the other platforms and boards.

I tested the regulator values and names after booting to see if the
names and values matched the expected values. They did, so I am
fairly confident it would have worked.

Do you want me to do a patch that removes the tp6507x.dtsi file and
just sets up the
PMIC from scratch within the da850-evm file?

Thank you. I think looks cleaner this way, and more consistent with
many of the other platforms and boards.

Not doubting that. But I am not sure if thats the "norm". Do you see any

The omap3 boards do this. For example, the beagle-xm board includes
the twl4030 files
#include "twl4030.dtsi"
#include "twl4030_omap3.dtsi"
These files setup the PMIC regulators, but the beagle-xm modifies the
PMIC settings phandles.
&vaux2 {
regulator-name = "usb_1v8";
regulator-min-microvolt = <1800000>;
regulator-max-microvolt = <1800000>;
regulator-always-on;
};
I was trying to mimic this behavior when I did it for the da850-evm,
however, it seems like a moot point we merge the
tp6507x.dtsi contents into the da850-evm.dts.

I'm going to try and revisit the LCD again first, but I'll try to do
them both this weekend if I can get some time.
