Some ahci_platform_data->init methods need access to the ahci_host_priv data.

Note:

When calling ahci_platform_data->init the ata_host has not been allocated yet,
so access to ahci_host_priv through the dev argument is not possible.

The hpriv->mmio argument may seem redundant, but it is useful for drivers
which live outside of drivers/ata and thus don't know the contents of the
ahci_platform_data data type.

Wouldn't the right thing to do be moving them under drivers/ata?

Yes, but they are part of arch/arm/mach-foo, so moving them is non trivial, and
I don't want to go make these kinda changes without hardware to test. Please keep
in mind that I'm partially cleaning up other peoples mess here (the imx bits
specifically). I'm willing to do that to some extend (*). But buying an imx6q board
and fixing that is about as far as I'm willing to go.

Regards,

Hans
