-Subject: [PATCH] arm64: dts: armada-3720-espressobin: correct spi node
-
-The manufacturer of this board, ships it with various SPI NOR chips and
-increments U-Boot bootloader version along the time. There is no way to
-tell which is placed on the board since no revision bump takes place.
-This creates two issues.
-
-The first, cosmetic. Since the SPI chip may differ, there's message on
-boot stating that kernel expected w25q32dw and found different one. To
-correct this, remove optional device-specific compatible string. Being
-here lets replace bogus "spi-flash" string with proper one.
-
-The second is linked to partitions layout, it changed after commit [1]
-in Marvells downstream U-Boot fork, shifting environment location to the
-end of boot device. Since the new boards can have U-Boot with this
-change it can lead to improper results writing or reading from these
-partitions. We can't tell if users will update bootloader to recent
-version, so let's drop current layout.
-
-1. https://github.com/MarvellEmbeddedProcessors/u-boot-marvell/commit/81e7251252aefe1a6b829ed05f3586320cb45372

-Subject: [PATCH] net: mvneta: Add support for 2500Mbps SGMII
-
-The mvneta controller can handle speeds up to 2500Mbps on the SGMII
-interface. This relies on serdes configuration, the lane must be
-configured at 3.125Gbps and we can't use in-band autoneg at that speed.
-
-The main issue when supporting that speed on this particular controller
-is that the link partner can send ethernet frames with a shortened
-preamble, which if not explicitly enabled in the controller will cause
-unexpected behaviours.
-
-This was tested on Armada 385, with the comphy configuration done in
-bootloader.

-Subject: [PATCH] net: mvneta: Don't advertise 2.5G modes
-
-Using 2.5G speed relies on the SerDes lanes being configured
-accordingly. The lanes have to be reconfigured to switch between
-1G and 2.5G, and for now only the bootloader does this configuration.
-
-In the case we add a Comphy driver to handle switching the lanes
-dynamically, it's better for now to stick with supporting only 1G and
-add advertisement for 2.5G once we really are capable of handling both
-speeds without problem.
-
-Since the interface mode is initialy taken from the DT, we want to make
-sure that adding comphy support won't break boards that don't update
-their dtb.

-
-Update the driver to semantics similar to mvpp2: helper
-mvneta_comphy_init sets comphy mode and powers it on.
-When mode is to be changed in mvneta_mac_config, first power the comphy
-off, then call mvneta_comphy_init (which sets the mode to new one).
-
-Only do this when new mode is different from old mode.
-
-This should also work for Armada 38x, since in that comphy driver
-methods power_on and power_off are unimplemented.

-Subject: [PATCH] net: mvneta: Add 2500BaseT support
-
-Some PHYs will use the 2500BaseX PHY_INTERFACE_MODE when being linked
-with a partner using 2.5GBaseT.
-
-Since we can't autonegotiate this speed between the MAC and the PHY, we
-need to have the proper comphy support enabled, to make sure we can
-safely advertise 2.5G and 1G in BaseT and be able to switch between both
-corresponding PHY interface modes. This is now possible since comphy
-support was added to this driver.
-
-This commit adds the 2500BaseT mode to the list of supported modes when
-using 2500BaseX, and was tested on a setup with an Armada385 and a
-88E2010 PHY, both with and without the comphy node in the DT.

-Subject: [PATCH] phy: fix build breakage: add PHY_MODE_SATA
-
-Commit 49e54187ae0b ("ata: libahci_platform: comply to PHY framework") uses
-the PHY_MODE_SATA, but that enum had not yet been added. This caused a
-build failure for me, with today's linux.git.
-
-Also, there is a potentially conflicting (mis-named) PHY_MODE_SATA, hiding
-in the Marvell Berlin SATA PHY driver.
-
-Fix the build by:
-
- 1) Renaming Marvell's defined value to a more scoped name,
- in order to avoid any potential conflicts: PHY_BERLIN_MODE_SATA.
-
- 2) Adding the missing enum, which was going to be added anyway as part
- of [1].

-Subject: [PATCH] phy: core: rework phy_set_mode to accept phy mode and submode
-
-Currently the attempt to add support for Ethernet interface mode PHY
-(MII/GMII/RGMII) will lead to the necessity of extending enum phy_mode and
-duplicate there values from phy_interface_t enum (or introduce more PHY
-callbacks) [1]. Both approaches are ineffective and would lead to fast
-bloating of enum phy_mode or struct phy_ops in the process of adding more
-PHYs for different subsystems which will make them unmaintainable.
-
-As discussed in [1] the solution could be to introduce dual level PHYs mode
-configuration - PHY mode and PHY submode. The PHY mode will define generic
-PHY type (subsystem - PCIE/ETHERNET/USB_) while the PHY submode - subsystem
-specific interface mode. The last is usually already defined in
-corresponding subsystem headers (phy_interface_t for Ethernet, enum
-usb_device_speed for USB).
-
-This patch is cumulative change which refactors PHY framework code to
-support dual level PHYs mode configuration - PHY mode and PHY submode. It
-extends .set_mode() callback to support additional parameter "int submode"
-and converts all corresponding PHY drivers to support new .set_mode()
-callback declaration.
-The new extended PHY API
- int phy_set_mode_ext(struct phy *phy, enum phy_mode mode, int submode)
-is introduced to support dual level PHYs mode configuration and existing
-phy_set_mode() API is converted to macros, so PHY framework consumers do
-not need to be changed (~21 matches).

- node
-
-Describe the A3700 COMPHY node. It has three PHYs that can be
-configured as follow:
-* PCIe or GbE
-* USB3 or GbE
-* SATA or USB3
-Each of them has its own memory area.

-Subject: [PATCH 657/660] arm64: dts: uDPU: fix comphy definitions
-
-The uDPU uses both ethernet controllers, which ties up COMPHY 0 for
-eth1 and COMPHY 1 for eth0, with no USB3 comphy. The addition of
-COMPHY support made the kernel override the setup by the boot loader
-breaking this platform. Delete the USB3 COMPHY definition at platform
-level, and add phy specifications for the ethernet channels.
