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.

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

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

No lpc in Yosemite so please remove.

Same here remove.
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.

uart1-4 are all assigned for 4 multiple hosts so define accordingly.
Also needs pinctrl configuration.

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

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.

Also needs pinctrl configuration.

Again needs pinctrl.

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

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.
