This is rebase of v3 on top of 'tty-next', to get rid of commits that
are already adopted to mainline.
RTS signal and RTS/CTS handshake handling had a few problems these
patches fix.
In addition, minor cleanups are made to the involved code.
Changelog:
v6:
* changed "Reviewed-by:"
Uwe Kleine-König <u.kleine-koenig@xxxxxxxxxxxxxx>
to "Acked-by:" him, according to his request
v5:
* improved commit description and added more comments for
"serial: imx: set_termios(): do not enable autoRTS if RTS is
unset" as suggested by
Uwe Kleine-König <u.kleine-koenig@xxxxxxxxxxxxxx>
and added corresponding "Reviewed-by:"
v4:
* rebased on top of 'tty-next', to get rid of commits that
are already adopted to mainline.
v3:
* Improved comments in "serial: imx: set_mctrl(): correctly
restore autoRTS state", as suggested by Uwe Kleine-König
<u.kleine-koenig@xxxxxxxxxxxxxx>
v2:
* Appended: "Reviewed-by:" and "Tested-by:"
Sascha Hauer <s.hauer@xxxxxxxxxxxxxx>
* Removed "RFC" from header
v1:
* Fixed in "serial: imx: set_termios(): preserve RTS state"
-+ ucr2 = UCR2_SRST | UCR2_IRTS;
++ ucr2 |= UCR2_SRST | UCR2_IRTS;
as noticed by Lothar Waßmann <LW@xxxxxxxxxxxxxxxxxxx>
* Fixed in "serial: imx: set_termios(): preserve RTS state"
-+ ucr2 = old_ucr2 & (UCR2_TXEN | UCR2_RXEN | UCR2_ATEN | UCR2_CTSC);
++ ucr2 = old_ucr2 & (UCR2_TXEN | UCR2_RXEN | UCR2_ATEN | UCR2_CTS);
as the fix for the problem found by Sascha Hauer
<s.hauer@xxxxxxxxxxxxxx>
* Reordered:
serial: imx: set_termios(): preserve RTS state
serial: imx: set_termios(): do not enable autoRTS if RTS is unset
as the latter makes sense only provided the former is already
applied.
