Subject: [PATCH 19/26] serial: bfin-uart: Fix auto CTS
Date: Tue, 2 Sep 2014 17:39:28 -0400 [thread overview]
Message-ID: <1409693975-1028-20-git-send-email-peter@hurleysoftware.com> (raw)
In-Reply-To: <1409693975-1028-1-git-send-email-peter@hurleysoftware.com>
Commit 64851636d568ae9f167cd5d1dcdbfe17e6eef73c,
serial: bfin-uart: Remove ASYNC_CTS_FLOW flag for hardware automatic CTS,
open-codes uart_handle_cts_change() when CONFIG_SERIAL_BFIN_HARD_CTSRTS
to skip start and stop tx.
But the CTS interrupt handler _still_ calls uart_handle_cts_change();
only call uart_handle_cts_change() if !CONFIG_SERIAL_BFIN_HARD_CTSRTS.
