From: Jakub Kicinski Date: Fri, 29 May 2015 19:20:26 +0000 (+0200) Subject: sc16is7xx: remove RS-485 delay RTS handling X-Git-Tag: omap-for-v4.2/wakeirq-drivers-v2^2~22 X-Git-Url: https://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5451bb29f725c099e7ea78262610c8c1b6caf008;p=pandora-kernel.git sc16is7xx: remove RS-485 delay RTS handling Users of RS-485 can request via ioctl that RTS signals should be activated selected number of milliseconds before the actual data transmission or delay reception certain number of milli- seconds after the transmission is finished. In sc16is7xx, however, RTS signalling is handled by the hardware and driver has no way of providing this feature. We still try to provide .delay_rts_before_send by delaying transmission but without actual effect on the RTS line. Note: this change will make the driver return -EINVAL when the feature is requested (.delay_rts_after_send is set).
