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.

Something I'm intending to fix in the devicetrees using LPC is to hog
the pins in the pinctrl node. You should consider doing the same here.

Strongly suggest adding the pinctrl properties here to ensure
exclusive access for the ADC pins.
Otherwise it looks reasonable.

uart1-4 are all assigned for 4 multiple hosts so define accordingly.

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

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.
