Since commit 1cf6e8fc8341 ("tty/serial: at91: fix RTS line management when hardware handshake is enabled"), hardware handshake is not working anymore on SAM9x5 platforms.
The first two patches fix the hardware handshake when CTS/RTS pins are handle by GPIOs.
The last patch fixes hardware handshake when CTS/RTS pins are not GPIOs.
Changes since v1: - Correct patch 1 with the error found by kbuild. - Add Alexandre's Acked-by on patch 2 - Rewrite patch 3 logic in the light of the on-going discussion with Cyrille and Alexandre.
NB: patch 2 NEEDS patch 1 to compile.
Richard Genoud (3): serial: mctrl_gpio: implement mctrl_gpio_use_rtscts tty/serial: at91: fix hardware handshake with GPIOs tty/serial: at91: fix hardware handshake when DMA is not used
