Subject: [PATCH 2/2] pch_uart: revert Kconfig for non-DMA mode
Date: Fri, 28 Jan 2011 18:00:02 +0900 [thread overview]
Message-ID: <1296205202-3799-2-git-send-email-tomoya-linux@dsn.okisemi.com> (raw)
In-Reply-To: <1296205202-3799-1-git-send-email-tomoya-linux@dsn.okisemi.com>
PCH_DMA is not always enabled when a user uses PCH_UART.
Since overhead of DMA is not small, in case of low frequent communication,
without DMA is better.
Thus, "select PCH_DMA" and DMADEVICES are unnecessary
