Hi,
The current implementation of the libahci allows using one PHY per
port but we still have one single regulator for the whole
controller. This series adds the support of multiple regulators.
This is the third version of the series.
I use now the same binding introduced in the first version. This one
was acked in the first place by Hans and was discussed during the
review of the second version.
To be able to use it, I made the port the platform devices when the
device tree was used. An other change was to manage the deferred
case. The regulator were now attached to a different device that the
SATA host, so the devres_release_group don't manage them, and they
have to be released in a separate call.
Thanks,
Grégory
Changelog:
v2 -> v3:
- put back the regulator inside the sub-node ports
- made the ports platform devices when the device tree is used
- released the regulator in case of error in the probe function
v1 -> v2:
- Kept the case when no child node are present under the ahci node
- Fix the test done under the label disable_target_pwrs
- No more use an of_ version of the regulator framework and instead
associate each regulator of a port with an unique name.
- Added the acked-by on the clean-up patch
