From e4305f0c500cc2b8ca8d6ca2fb74fb76bf2cb6ad Mon Sep 17 00:00:00 2001 From: Roland Stigge Date: Mon, 11 Jun 2012 21:57:14 +0200 Subject: serial/of-serial: Add LPC3220 standard UART compatible string This patch adds a "compatible" string for the new 8250 UART type PORT_LPC3220. This is necessary for initializing LPC32xx UARTs via DT.

The 8250 driver uses the UPF_SKIP_TEST flag to indicate this, however it is not possible to set this flag via device-tree. Add a new 'no-loopback-test' property, and modify the of_serial driver to set the UPF_SKIP_TEST flag if the property is present.
