Hello,
v1 of this series consisted only of the third patch in this series. When
I sent it (Message-Id:
20171218094148.13732-1-u.kleine-koenig@xxxxxxxxxxxxxx) Tobias had doubts
because my patch resulted in an enabled read ready interrupt even though
the irq line should be unused. So I added patch 2 in front which ensures
that irqs are not enabled in this case also in other parts of the driver.
While at it I noticed that only a part of the register accesses used the
port's regshift member to calculate register offset and so fixed that in
another patch before.
This patch set was tested only on a machine that doesn't make use of the
irq line. For that reception of characters works starting with the final
patch in this series.
Uwe Kleine-König (3):
serial: altera: ensure port->regshift is honored consistently
serial: altera: don't enable any irq if the device doesn't feature an
irq
serial: altera: set RRDY flag also without irq
