Subject: [PATCH v8 0/7] usb: add support for the generic PHY framework

The series can be found at:
git://git.free-electrons.com:users/antoine-tenart/linux.git usb-phy

Changes since v7:
- rebased on top of Felipe's testing/next branch

Changes since v6:
- rebased on top of v3.18-rc2

Changes since v5:
- rebased on the latest version of Sergei's series[1]
- fixed one modifiaction made in the wrong patch

Changes since v4:
- reworked the PHY handling in ci_hdrc_probe()
- fixed a rebase error

Changes since v3:
- moved phy_exit() after phy_power_on()
- fixed the PHY handling in ci_hdrc_probe()
- some little fixes

Changes since v2:
- rebased the series on top of v3.17-rc1
- switched to devm_phy_get() to handle non DT cases
- moved usb_otg into the ci_hdrc structure

Changes since v1:
- rebased the series on top of [2] (generic PHY support for HCD)
- split s/phy/usb_phy/ renaming and generic PHY support in separate
patches

[1] https://www.mail-archive.com/linux-usb%40vger.kernel.org/msg48068.html

Antoine Tenart (7):
usb: move the OTG state from the USB PHY to the OTG structure
usb: rename phy to usb_phy in OTG
usb: add support to the generic PHY framework in OTG
usb: allow to supply the PHY in the drivers when using HCD
usb: chipidea: rename transceiver and phy to usb_phy
usb: chipidea: move usb_otg into struct ci_hdrc
usb: chipidea: add support to the generic PHY framework

Subject: [PATCH v8 3/7] usb: add support to the generic PHY framework in OTG

This patch adds support of the PHY framework in OTG and keeps the USB
PHY compatibility. Here the only modification is to add PHY member in
the OTG structure, along with the USB PHY one.

Subject: [PATCH v8 7/7] usb: chipidea: add support to the generic PHY framework

This patch adds support of the PHY framework for ChipIdea drivers.
Changes are done in both the ChipIdea common code and in the drivers
accessing the PHY. This is done by adding a new PHY member in
ChipIdea's structures and by taking care of it in the code.

Subject: [PATCH v8 5/7] usb: chipidea: rename transceiver and phy to usb_phy

This patch prepares the introduction of the generic PHY support in the
USB ChipIdea common functions. The USB PHY member of the ChipIdea
structure ('transceiver') is renamed to 'usb_phy', the 'phy' member of
the ChipIdea pdata structure is renamed to 'usb_phy' and modifications
are done in all drivers accessing it. Renaming this pointer will allow
to keep the compatibility for USB PHY drivers.

Subject: [PATCH v8 4/7] usb: allow to supply the PHY in the drivers when using HCD

This patch modify the generic code handling PHYs to allow them to be
supplied from the drivers. This adds checks to ensure no PHY was already
there when looking for one in the generic code. This also makes sure we
do not modify its state in the generic HCD functions, it was provided by
the driver.

Subject: [PATCH v8 2/7] usb: rename phy to usb_phy in OTG

This patch prepares the introduction of the generic PHY support in the
USB OTG common functions. The USB PHY member of the OTG structure is
renamed to 'usb_phy' and modifications are done in all drivers accessing
it. Renaming this pointer will allow to keep the compatibility for USB
PHY drivers.

Subject: [PATCH v8 1/7] usb: move the OTG state from the USB PHY to the OTG structure

Before using the PHY framework instead of the USB PHY one, we need to
move the OTG state into another place, since it won't be available when
USB PHY isn't used. This patch moves the OTG state into the OTG
structure, and makes all the needed modifications in the drivers
using the OTG state.

Hi Felipe,

I find you queue the patch 1st-4th and 7th in your next tree, how you queue
the 7th without queueing 5th and 6th, they have some relationships.

Will you queue 5th and 6th, or I queue them (5th- 7th) through my chipidea patch set?

Peter

argh, somehow I missed them. I'll add both to my testing/next. Sorry for
the confusion. I thought I had them all.

Hi Felipe, I still not see Antoine's chipidea patch in your tree.
I assume you will do it soon.
And there are some coming chipidea patches (Antoine & me), I will do
further work based on it.

Oh, I know the reason why you can apply 7th, without apply 5th and 6th.
At your next tree, the 4th, 5th, and 6th patches were squashed, and
it becomes "4th" patches in this series.
The shortlog is:
usb: allow to supply the PHY in the drivers when using HCD
commit id is:
"ef44cb4226d132146e44f8ea562a16b27ff61126"

hmmm... not sure how I did that. Probably squashed them to avoid some
build failures...
