sata_rcar: Remove ata_host_alloc() error printing

2019-05-09T17:19:32+00:00

ata_host_alloc() can only fail due to memory allocation failures.
Hence there is no need to print a message, as the memory allocation core
code already takes care of that.

sata_rcar: fix deferred probing

2018-12-10T18:10:31+00:00

The driver overrides the error codes returned by platform_get_irq() to
-EINVAL, so if it returns -EPROBE_DEFER, the driver would fail the probe
permanently instead of the deferred probing. Switch to propagating the
error code upstream, still checking/overriding IRQ0 as libata regards it
as "no IRQ" (thus polling) anyway...

ata: sata_rcar: exclude setting of PHY registers in Gen3

2018-08-06T17:25:34+00:00

According to documentation, setting of PHY registers is unnecessary with
R-Car Gen3. The registers are not even described. So, don't initialize
them.

ata: sata_rcar: really mask all interrupts on Gen2 and later

2018-08-06T17:25:01+00:00

Since R-Car Gen2, a new bit has been introduced to the interrupt mask
register. Update the code to handle it properly as well.

ata: sata_rcar: Add rudimentary Runtime PM support

2018-07-23T15:18:43+00:00

Replace the explicit clock handling to enable/disable the SATA module by
calls to Runtime PM.

This makes the driver independent of actual SoC clock/power hierarchies,
and is needed to support virtualization, where the guest is not in full
control of power management.

sata_rcar: Reset SATA PHY when Salvator-X board resumes

2018-02-12T17:22:36+00:00

Because power of Salvator-X board is cut off in suspend,
it needs to reset SATA PHY state in resume.
Otherwise, SATA partition could not be accessed anymore.

ata: sata_rcar: Use of_device_get_match_data() helper

2017-10-04T14:18:29+00:00

Use the of_device_get_match_data() helper instead of open coding.
Note that the sata_rcar driver is used with DT only, so there's always a
valid match.
