Date: Fri, 18 Apr 2014 11:22:44 +0200 From: Jiri Slaby <jslaby@...e.cz> To: stable@...r.kernel.org Cc: linux-kernel@...r.kernel.org, Vineet Gupta <vgupta@...opsys.com>, Francois Bedard <Francois.Bedard@...opsys.com>, Jiri Slaby <jslaby@...e.cz> Subject: [PATCH 3.12 71/72] ARC: [nsimosci] Unbork console From: Vineet Gupta <vgupta@...opsys.com> 3.12-stable review patch. If anyone has any objections, please let me know. =============== commit 61fb4bfc010b0d2940f7fd87acbce6a0f03217cb upstream. Despite the switch to right UART driver (prev patch), serial console still doesn't work due to missing CONFIG_SERIAL_OF_PLATFORM Also fix the default cmdline in DT to not refer to out-of-tree ARC framebuffer driver for console.
