This required to add two functions down the stack to uart.c and ra.sci.c. - One for telling, whther the transmission is busy. - One for reporting the size of the TX buffer. Tested with a EK-RA6M2 board.
Changes are: - Support drive= keyword argument. - Fix trigger keyword check. - Fix GPIO pin setting. Signed-off-by: Takeo Takahashi <takeo.takahashi.xv@renesas.com>
