From c4cad90f9e9dcb85afc5e75a02ae3522ed077296 Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Tue, 3 Jun 2014 17:33:41 +1000 Subject: [PATCH] powerpc/serial: Use saner flags when creating legacy ports We had a mix & match of flags used when creating legacy ports depending on where we found them in the device-tree. Among others we were missing UPF_SKIP_TEST for some kind of ISA ports which is a problem as quite a few UARTs out there don't support the loopback test (such as a lot of BMCs). Let's pick the set of flags used by the SoC code and generalize it which means autoconf, no loopback test, irq maybe shared and fixed port. Sending to stable as the lack of UPF_SKIP_TEST is breaking serial on some machines so I want this back into distros Signed-off-by: Benjamin Herrenschmidt CC: stable@vger.kernel.org --- Reading git-format-patch failed
