* DT binding for arc-uart * With alll the bits in place we can now use DT probing. Note that there's a bit of kludge right now because earlyprintk portion of driver can't use the DT infrastrcuture to get resoures/plat_data. This requires some infrastructre changes to of_flat_ framework Signed-off-by: Vineet Gupta <vgupta@synopsys.com> Cc: Grant Likely <grant.likely@secretlab.ca> Cc: Arnd Bergmann <arnd@arndb.de> Cc: Alan Cox <alan@linux.intel.com> Cc: devicetree-discuss@lists.ozlabs.org Cc: Rob Herring <rob.herring@calxeda.com> Cc: Rob Landley <rob@landley.net> Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

* Synopsys ARC UART : Non standard UART used in some of the ARC FPGA boards
|
|
|
|
Required properties:
|
|
- compatible : "snps,arc-uart"
|
|
- reg : offset and length of the register set for the device.
|
|
- interrupts : device interrupt
|
|
- clock-frequency : the input clock frequency for the UART
|
|
- baud : baud rate for UART
|
|
|
|
e.g.
|
|
|
|
arcuart0: serial@c0fc1000 {
|
|
compatible = "snps,arc-uart";
|
|
reg = <0xc0fc1000 0x100>;
|
|
interrupts = <5>;
|
|
clock-frequency = <80000000>;
|
|
baud = <115200>;
|
|
status = "okay";
|
|
};
|
|
|
|
Note: Each port should have an alias correctly numbered in "aliases" node.
|
|
|
|
e.g.
|
|
aliases {
|
|
serial0 = &arcuart0;
|
|
};
