From ec3bebc6ec64aac23500e6b8ef5c0aaaeda735cf Mon Sep 17 00:00:00 2001 From: "Govindraj.R" Date: Tue, 11 Oct 2011 19:11:27 +0530 Subject: ARM: OMAP2+: UART: Get context loss count to context restore Avoid unconditional context restore every time we gate uart clocks. Check whether context loss happened based on which we can context restore uart regs from uart_port structure.
