[PATCH 11/76] serial: pch_uart: revert Kconfig for non-DMA mode

From: Greg Kroah-Hartman <gregkh@suse.de>
Date: 2011-03-16 21:13:06
Subsystem: the rest, tty layer and serial drivers · Maintainers: Linus Torvalds, Greg Kroah-Hartman, Jiri Slaby

From: Tomoya MORINAGA <redacted>

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
