From 3696fc9774c54e0599fe2d85e84211f26eead8b8 Mon Sep 17 00:00:00 2001 From: Eugeniy Paltsev Date: Wed, 23 Oct 2019 15:44:12 +0300 Subject: [PATCH] ARC: HAPS: use same UART configuration everywhere For some reason we use ns8250 UART compatible on UP HAPS configuration and ns16550a (which is ns8250 with FIFO support) on SMP HAPS configuration. Given that we have same UART IP with same IP configuration on both HAPS configuration use ns16550a compatible everywhere.
