From b03408500e60a5f8142a1ba73949e523c059c265 Mon Sep 17 00:00:00 2001 From: "J.D. Schroeder" Date: Thu, 22 Oct 2015 19:24:16 -0500 Subject: ARM: DRA7: hwmod: Enable DEBUG_LL for UART4 UART4 low level debug support. This helps in debugging with UART4 serial console output on DRA7 based platforms. Extending the following fix for UART4. commit 1c7e36bfc3e2 ("ARM: DRA7: hwmod: Fix boot crash with DEBUG_LL enabled on UART3") For using DEBUG_LL, enable CONFIG_DEBUG_OMAP4UART4 in menuconfig. On DRA7, UART4 hwmod doesn't have this flag enabled, failure observed when UART4 is used for low level debugging. Hence, Enable DEBUG_OMAP4UART4_FLAGS for UART4 hwmod. Signed-off-by: J.D.
