hex number case in dts files.

hex number case in dts files.

[David Brown]

I've noticed an inconsistency in the case of letters in hex constants
in various dts files.  The ones that are actually numbers probably
don't really matter, the but the node names are case sensitive
strings, and in some sense do matter.

I ask because some people I've spoken with internally seem to have
strong opinions about what case hex constants should be, and it'd be
nice to be able to have some guideline about this.  Historically, I've
always seen DT hex values in lowercase.

Thanks,
David

Lower case should be used for dts files.

Yes, the node names should always have the hex done in lower case.  I
have plans to put more checks in for how reg is encoded into node
names, but just need to get time.

Yes, the node names should always have the hex done in lower case.  I

What about number of digits?  Should a register at 0x42 be
node at 00000042 or node at 42?  Again, I'm seeing both.

What about number of digits?  Should a register at 0x42 be
node@00000042 or node@42?  Again, I'm seeing both.

It depends on the binding of the parent node.  Most use no
leading zeroes except when representing 0 itself.
