Subject: [PATCH 0/4] pata: imx: set timings for PIO modes up to PIO4
Date: Wed, 9 Nov 2016 02:56:34 +0200 [thread overview]
Message-ID: <20161109005638.17691-1-vz@mleia.com> (raw)
The changeset adds support of PIO modes up to PIO4 by setting
necessary timings in the driver, before the change it is assumed
that the timings are always set by a bootloader once and thus
only one possible PIO mode has been supported (PIO0). With
this change the driver can be used on boards without ATA controller
configuration done by a bootloader.
The change is tested on a legacy i.MX31 board with an HDD connected
by a 40-pin flat cable.
