ata: ahci_platform: fix ahci_platform_data->suspend method handling

2014-03-25T19:17:13+00:00

Looking at ST SPEAr1340 AHCI code (the only user of the deprecated
pdata->suspend and pdata->resume) it is obvious the we should return
after calling pdata->suspend() only if the function have returned
non-zero return value.  The code has been broken since commit 1e70c2
("ata/ahci_platform: Add clock framework support").  Fix it.

ata: ahci_platform: fix devm_ioremap_resource() return value checking

2014-03-14T18:30:28+00:00

devm_ioremap_resource() returns a pointer to the remapped memory or
an ERR_PTR() encoded error code on failure.  Fix the check inside
ahci_platform_get_resources() accordingly.

Also while at it remove a needless line break.

ahci_platform: Drop unused ahci_platform_data members

2014-02-22T22:13:01+00:00

These members are not used anywhere, and in the future we want
ahci_platform_data to go away entirely so there is no reason to keep these
around.

ahci_platform: Drop support for imx53-ahci platform device type

2014-02-22T22:13:01+00:00

Since the 3.13 release the ahci_imx driver has proper devicetree enabled
support for ahci on imx53 and that is used instead of the old board file
created imx53-ahci platform device.

Note this patch also complete drops the id-table, an id-table is not needed
for a single id platform driver, the name field in the driver struct suffices.

And the code already has an explicit "MODULE_ALIAS("platform:ahci");" so the
id-table is not needed for that either.

ahci_platform: Drop support for ahci-strict platform device type

2014-02-22T22:13:01+00:00

I've done a grep over the entire kernel tree and nothing is using this
(anymore?).

ata: ahci_platform: runtime resume the device before use

2014-02-22T20:35:43+00:00

On OMAP platforms the device needs to be runtime resumed before it can
be accessed. The OMAP HWMOD framework takes care of enabling the
module and its resources based on the device's runtime PM state.

In this patch we runtime resume during .probe() and runtime suspend
after .remove().

We also update the runtime PM state during .resume().

ata: ahci_platform: Manage SATA PHY

2014-02-22T20:35:43+00:00

Some platforms have a PHY hooked up to the SATA controller. The PHY
needs to be initialized and powered up for SATA to work. We do that
using the PHY framework.

ata: ahci_platform: Add DT compatible for Synopsis DWC AHCI controller

2014-02-22T20:35:42+00:00

Add compatible string "snps,dwc-ahci", which should be used
for Synopsis Designware SATA cores. e.g. on TI OMAP5 and DRA7 platforms.

functions.
