Subject: [PATCH 0/2] Fix Arm Ltd board node name collisions

The node name changes in commits 25b892b583cc ("ARM: dts: arm: Update 
register-bit-led nodes 'reg' and node names") and 2d3de197a818 ("ARM: 
dts: arm: Update ICST clock nodes 'reg' and node names") caused name 
collisions with the kernel's handling of ICST clock names and platform 
device names. This series fixes the kernel side to handle the DT 
changes.

This does break DT ABI compatibility which is partially mitigated if 
these changes are backported to stable. The alternative is reverting the 
referenced DT changes and coming up with different node names without 
unit-addresses. Ultimately, ABI issues are platform maintainers' 
decision, not mine.
