Subject: [PATCHv2 0/3] Fix handware handshake on SAM9x5 platforms
Date: Mon, 12 Sep 2016 11:47:30 +0200 [thread overview]
Message-ID: <20160912094733.21501-1-richard.genoud@gmail.com> (raw)
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.
