Subject: [PATCH 1/2] ARM: am33xx: Pass uart_base to soft_reset function
Date: Thu, 15 May 2014 10:54:07 +0200	[thread overview]
Message-ID: <1400144048-7933-1-git-send-email-s.hauer@pengutronix.de> (raw)

To make am33xx_uart0_soft_reset more flexible rename it to
am33xx_uart_soft_reset and pass the UART base to it.
