[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
v4: Change clock name to pata_imx

this breaks the alphabetic ordering in this file.
arch/arm/plat-mxc/devices/Makefile is affected, too.

Other than that I don't see any issues any more. Sascha, maybe you can
fix that up while committing (assuming nobody has more objections)?
Arnaud told me on irc that he is occupied and cannot follow up soon.

Best regards
Uwe

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.

Sascha
