: Allow UART parameters to be configured from board file.
Govindraj.R (13):
OMAP2+: hwmod: Add API to enable IO ring wakeup.
OMAP2+: hwmod: Add API to check IO PAD wakeup status
OMAP2+: UART: cleanup + remove uart pm specific API
OMAP2+: UART: cleanup 8250 console driver support
OMAP2+: UART
wakeup_flag is
set or cleared.
Call the omap_hwmod_set_ioring_wakeup from hwmod_wakeup_enable/disable.
