Adding devicetree ML to Cc. You may use an "aliases" node for that, if your UART driver supports that. The 8250/16550 driver does. See arch/arm/boot/dts/aspeed-ast2500-evb.dts, for example. Note though that the use of aliases for this purpose is contentious. baruch -- http://baruch.siach.name/blog/ ~. .~ Tk Open Systems =}------------------------------------------------ooO--U--Ooo------------{= - baruch at tkos.co.il - tel: +972.52.368.4656, http://www.tkos.co.il - ^ permalink raw reply [flat|nested] 2+ messages in thread
