Wolfgang Denk	7ec8bb15ee	OMAP5912: fix FIFO handling in UART driver According to the OMAP5912 Serial Interfaces Reference Guide (see http://focus.ti.com/lit/ug/spru760c/spru760c.pdf, page 150), the FIFO_EN enable bit in the FIFO Control Register (FCR) can only be changed when the baud clock is not running, i. e. when both DLL and DLH are set to 0. Thus make sure that DLL and DLH are 0 when writing the FCR. Signed-off-by: Wolfgang Denk <wd@denx.de>	2008-02-05 00:04:15 +01:00

OMAP5912: fix FIFO handling in UART driver

According to the OMAP5912 Serial Interfaces Reference Guide (see
http://focus.ti.com/lit/ug/spru760c/spru760c.pdf, page 150), the
FIFO_EN enable bit in the FIFO Control Register (FCR) can only be
changed when the baud clock is not running, i. e. when both DLL and
DLH are set to 0.

Thus make sure that DLL and DLH are 0 when writing the FCR.
