The patch titled
ARM i.MX serial: fix IRQ allocation
has been removed from the -mm tree. Its filename was
arm-imx-serial-fix-irq-allocation.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: ARM i.MX serial: fix IRQ allocation
From: Pavel Pisa <[EMAIL PROTECTED]>
If RTS interrupt is caused by RTS senzing logic inside i.MX UART module the
IRQ type cannot be set.
It applies only for interrupts going through GPIO layer. The problem has
been noticed by Konstantin Kletschke some time ago.
No IRQF_TRIGGER set_type function for IRQ 26 (MPU)
I would not change type to fixed 0, because it could be possible to use
different GPIO MX1 pin for RTS in the theory. On the other hand it is only
for documentation purposes now, because RTS read code would have to be
adjusted in such case.
