The Yosemite V2 is a facebook multi-node server
platform that host four OCP server. The BMC
in the Yosemite V2 platorm based on AST2500 SoC.

This patch adds linux device tree entry related to
Yosemite V2 specific devices connected to BMC SoC.

Hi Andrew/Vijay,

Thanks for the review .

The following changes done in dts and tested in Facebook Yosemite V2 BMC platform,
  1. LPC feature removed as not supported .
  2. VUART feature removed as not supported.
  3. Host UART feature removed as not in the current scope.
  4. ADC pinctrl details added in dts.

Thanks
Mani.E

Can you please re-send the patch as a v2 and inline to the mail rather than
as an attachment?

Is this necessary now that you're not enabling uart1?

But otherwise:

Acked-by: Andrew Jeffery <andrew@aj.id.au>

However, I'm guessing you copy/pasted the patch as we still have the
reply text at the bottom. Copy/paste can lead to mangled whitespace
or other errors that prevent the patch from being applied cleanly. I
recommend getting set up and familiar with `git send-email` to give
your patch the best chance of being applied without trouble. The
`git format-patch` / `git send-email` pair also take care of iterating
on your patch with e.g. the `-v` switch that injects the version number
of the patch in the appropriate places.
