Subject: ARM: dts: am335x-evm: Add DCAN1 details
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=f80ecaf55b4982a888272790743dabf2c715dc10;p=deliverable%2Flinux.git

ARM: dts: am335x-evm: Add DCAN1 details

DCAN1 is routed to CAN port (J11) when Profile 1 is selected on the
profile selection switch.
Provide information for DCAN1 pins and node but keep it disabled
by default. User has to manually enable it if Profile 1 is chosen.
