[PATCH 0/3] Enable myphy28lp support

[Gabriel FERNANDEZ]

The goal of this series is to enable the support of MiPHY28lp Generic PHY.

The first patch is to update miphy28lp phy driver to access sysconfig register
offsets via syscfg dt property. It's based on Arnds review comments here
https://lkml.org/lkml/2014/11/13/161
I have updated the miphy28lp phy driver same way as Peter's implementation.

    property.

    USB3) PHY

[PATCH 1/3] phy: miphy28lp: Pass sysconfig register offsets via syscfg dt property.

[Gabriel FERNANDEZ]

Based on Arnds review comments here https://lkml.org/lkml/2014/11/13/161,
update the miphy28lp phy driver to access sysconfig register offsets via
syscfg dt property.

This is because the reg property should not be mixing address spaces like
it does currently for miphy28lp. This change then also aligns us to how other
platforms such as keystone and bcm7445 pass there syscon offsets via DT.

I have updated the miphy28lp phy driver same way as Peter's implementation.

[PATCH 2/3] ARM: DT: STi: STiH407: Add DT node for MiPHY28lp

[Gabriel FERNANDEZ]

The MiPHY28lp is a Generic PHY which can serve various SATA, PCIe or
USB3 devices. The two first ports can be use for either; both SATA, both
PCIe or one of each in any configuration.
The Third port is only for USB3.

Hi Kishon,

     Don't apply the patch, since we have 2 other PHY driver patches, I 
will send you a pull request.
