1af824649b drm/pl111: Deprecate the pads from the DT binding
The pads were an earlier workaround for the internal image
pipeline in the Linux fbdev subsystem. As we move to generic
definition of display properties and drivers that no longer
need this to work, deprecate this property.

There is no strong reason for this to use CLK_OF_DECLARE instead
of being a platform driver. Plus, this will now be aligned with the
other i.MX8M clock drivers which are platform drivers.

In order to make the clock provider a platform driver
all the data and code needs to be outside of .init section.

The capability check for fan control in smu_v11_0_auto_fan_control was

====================
enetc: Add mdio bus driver for the PCIe MDIO endpoint

First patch fixes a sparse issue and cleans up accessors to avoid
casting to __iomem.  The second one cleans up the Makefile, to make
it easier to add new entries.

Third patch just registers the PCIe endpoint device containing
the MDIO registers as a standalone MDIO bus driver, to provide
an alternative way to control the MDIO bus.  The same code used
by the ENETC ports (eth controllers) to manage MDIO via local
registers applies and is reused.

Bindings are provided for the new MDIO node, similarly to ENETC
port nodes bindings.

Last patch enables the ENETC port 1 and its RGMII PHY on the
LS1028A QDS board, where the MDIO muxing configuration relies
on the MDIO support provided in the first patch.

Changes since v0:
v1 - fixed mdio bus allocation
v2 - cleaned up accessors to avoid casting
v3 - fixed spelling (mostly commit message)
v4 - fixed err path check blunder
v5 - fixed loadble module build, provided separate kbuild module
     for the driver

8488d8e90c arm64: dts: fsl: ls1028a: Enable eth port1 on the ls1028a QDS board
LS1028a has one Ethernet management interface. On the QDS board, the
MDIO signals are multiplexed to either on-board AR8035 PHY device or
to 4 PCIe slots allowing for SGMII cards.
To enable the Ethernet ENETC Port 1, which can only be connected to a
RGMII PHY, the multiplexer needs to be configured to route the MDIO to
the AR8035 PHY.  The MDIO/MDC routing is controlled by bits 7:4 of FPGA
board config register 0x54, and value 0 selects the on-board RGMII PHY.
The FPGA board config registers are accessible on the i2c bus, at address
0x66.

The PF3 MDIO PCIe integrated endpoint device allows for centralized access
to the MDIO bus.  Add the corresponding devicetree node and set it to be
the MDIO bus parent.

231ece36f5 enetc: Add mdio bus driver for the PCIe MDIO endpoint
ENETC ports can manage the MDIO bus via local register
interface.  However there's also a centralized way
to manage the MDIO bus, via the MDIO PCIe endpoint
device integrated by the same root complex that also
integrates the ENETC ports (eth controllers).

Depending on board design and use case, centralized
access to MDIO may be better than using local ENETC
port registers.  For instance, on the LS1028A QDS board
where MDIO muxing is required.  Also, the LS1028A on-chip
switch doesn't have a local MDIO register interface.

The current patch registers the above PCIe endpoint as a
separate MDIO bus and provides a driver for it by re-using
the code used for local MDIO access.  It also allows the
ENETC port PHYs to be managed by this driver if the local
"mdio" node is missing from the ENETC port node.

aa6b195615 net: phy: fix race in genphy_update_link
In phy_start_aneg() autoneg is started, and immediately after that
link and autoneg status are read. As reported in [0] it can happen that
at time of this read the PHY has reset the "aneg complete" bit but not
yet the "link up" bit, what can result in a false link-up detection.
To fix this don't report link as up if we're in aneg mode and PHY
doesn't signal "aneg complete".

====================
net: dsa: mv88e6xxx: add support for MV88E6220

This patch series adds support for the MV88E6220 chip to the mv88e6xxx driver.
The MV88E6220 is almost the same as MV88E6250 except that the ports 2-4 are
not routed to pins.

Furthermore, PTP support is added to the MV88E6250 family.

v2:
 - insert all 6220 entries in correct numerical order
 - introduce invalid_port_mask
 - move ptp_cc_mult* to ptp_ops and restored original ptp_adjfine code
 - added Andrews Reviewed-By to patch 2 and 4
