pch_uart: reference clock on CM-iTC

2011-03-14T23:24:23+00:00

Default clock source for UARTs on Topcliff is external UART_CLK.
On CM-iTC USB_48MHz is used instead. After VCO2PLL and DIV
manipulations UARTs will receive 192 MHz.
Clock manipulations on Topcliff are controlled in pch_phub.c

v2: redone against the linux-next tree
v3: redone against linux/kernel/git/next/linux-next.git snapshot

pch_uart: add multi-scatter processing

2011-02-23T01:22:02+00:00

Currently, this driver can handle only single scatterlist.
Thus, it can't send data beyond FIFO size.

This patch enables this driver can handle multiple scatter list.
