[patch 0/3] imx: Efika: Add pata device

[Arnaud Patard (Rtp)]

This patchset is adding ressources, clock and device declarations for the
pata device available on imx51. Last patch enables pata on efika platforms.
To be complete, this patchset needs a driver, which is about to be sent for
merge to ata developers.

v2: Created a imx51_add_mxc_pata() as suggested
v3: Fix naming

First argument to _REGISTER_CLOCK must match the device name, but the
driver you posted uses pata_imx as device name. The second argument
which you correctly set to NULL here is an additional identifier which
must match if it exists. There is only one clock in the pata driver, so
you should use clk_get(&pdev->dev, NULL) in you driver.

I'd prefer to have imx51_add_mxc_pata() which expands to
imx_add_mxc_pata(&imx51_mxc_pata_data)

Why didn't you add that?
