[PATCH 0/3] arm: Add Analog Devices SC5xx Machine Type

This series adds support for the ADI SC5xx machine type and includes two
core drivers that are required for being able to boot any board--a UART
driver and the clock tree driver. Our corresponding Linux support relies
on u-boot configuring the clocks correctly before booting, so it is not
possible to boot any board without the CGU/CDU configuration happening
here. The clock tree itself is only used by the UART in this minimal
patch set, but is of course broadly useful for all other peripheral
drivers to be submitted in future patch sets. There are also no board
files or defconfigs included here, but some common definitions that will
be used to build board files currently are.

Some of the configuration code in dmcinit and clkinit is quite scary and
causes a lot of checkpatch violations. It is modified from code
initially provided by ADI, but it has not been fully rewritten. There's
a question of how important it is to clean up this code--it has some
quality violations, but it has been in use (including in production) for
over two years and is known to work for performing the low level SoC
initialization, while a rewrite might introduce bugs that could take a
significant amount of time to detect in the future.

Please provide any feedback or comments that will be helpful in creating
a v2 of this patch that will be ready to submit for inclusion into the
main tree, as well as general observations that we should consider in
other driver patches before submitting them.

Thank you!
