Subject: [PATCH net-next v3 00/13] net: mvpp2: comphy configuration
Date: Mon, 28 Aug 2017 16:57:12 +0200	[thread overview]
Message-ID: <20170828145725.2539-1-antoine.tenart@free-electrons.com> (raw)

Hi all,

This series, following up the one one the GoP/MAC configuration, aims at
stopping to depend on the firmware/bootloader configuration when using
the PPv2 engine. With this series the PPv2 driver does not need to rely
on a previous configuration, and dynamic reconfiguration while the
kernel is running can be done (i.e. switch one port from SGMII to 10G,
or the opposite). A port can now be configured in a different mode than
what's done in the firmware/bootloader as well.

The series first contain patches in the generic PHY framework to support
what is called the comphy (common PHYs), which is an h/w block providing
PHYs that can be configured in various modes ranging from SGMII, 10G
to SATA and others. As of now only the SGMII and 10G modes are
supported by the comphy driver.

Then patches are modifying the PPv2 driver to first add the comphy
initialization sequence (i.e. calls to the generic PHY framework) and to
then take advantage of this to allow dynamic reconfiguration (i.e.
configuring the mode of a port given what's connected, between sgmii and
10G). Note the use of the comphy in the PPv2 driver is kept optional
(i.e. if not described in dt the driver still as before an relies on the
firmware/bootloader configuration).

Finally there are dt/defconfig patches to describe and take advantage of
this.

This was tested on a range of devices: 8040-db, 8040-mcbin and 7040-db.

Thanks!
Antoine

Since v2:
  - Kept the link mode enforcement.
  - Removed the netif_running() check.
  - Reworded the "dynamic reconfiguration of the PHY mode" commit log.
  - Added one patch not to force the GMAC autoneg parameters when using
    the XLG MAC.

Since v1:
  - Updated the mode settings variable name in the comphy driver to
    have 'cp110' in it.
  - Documented the PHY cell argument in the dt documentation.
  - New patch adding comphy phandles for the 7040-db board.
  - Checked if the carrier_on/off functions were needed. They are.
  - s/PHY/generic PHY/ in commit log of patch 1.
  - Rebased on the latest net-next/master.
