Lee Jones 6e877fedb1 phy: miphy365x: Provide support for the MiPHY356x Generic PHY
The MiPHY365x is a Generic PHY which can serve various SATA or PCIe
devices. It has 2 ports which it can use for either; both SATA, both
PCIe or one of each in any configuration.

Srinivas Kandagatla 175f02ebdf phy: qcom-apq8064: fix possible timeout without check
This patch fixes a possible timeout in poll loop without actually
checking the register before return. In theory the there is a possibility
of loop being scheduled after a long lock/delay, which would then force
the loop to exit without actually checking the register.

Kishon Vijay Abraham I f0ed817638 phy: core: Let node ptr of PHY point to PHY and not of PHY provider
In case of multi-phy PHY providers, each PHY should be modeled as a sub
node of the PHY provider. Then each PHY will have a different node pointer
(node pointer of sub node) than that of PHY provider. Added this provision
in the PHY core.
Also fixed all drivers to use the updated API.

Antoine Ténart 942a31b521 phy: add a driver for the Berlin SATA PHY
The Berlin SoC has a two SATA ports. Add a PHY driver to handle them.

The mode selection can let us think this PHY can be configured to fit
other purposes. But there are reasons to think the SATA mode will be
the only one usable: the PHY registers are only accessible indirectly
through two registers in the SATA range, the PHY seems to be integrated
and no information tells us the contrary. For these reasons, make the
driver a SATA PHY driver.

of the dependency on the exynos{5250,4x12,4210}_usb2_phy_config

Hans de Goede b51fbf9fb0 phy-core: Don't allow building phy-core as a module
include/phy/phy.h has stub code in there for when building without the
phy-core enabled. This is useful for generic drivers such as ahci-platform,
ehci-platoform and ohci-platform which have support for driving an optional
phy passed to them through the devicetree.

Since on some boards this phy functionality is not needed, being able to
disable the phy subsystem without needing a lot of #ifdef magic in the
driver using it is quite useful.

However this breaks when the module using the phy subsystem is build-in and
the phy-core is not, which leads to the build failing with missing symbol
errors in the linking stage of the zImage.

Which leads to gems such as this being added to the Kconfig for achi_platform:

	depends on GENERIC_PHY || !GENERIC_PHY

Rather then duplicating this code in a lot of places using the phy-core,
I believe it is better to simply not allow the phy-core to be built as a
module. The phy core is quite small and has no external dependencies, so
always building it in when enabling it should not be an issue.

Andrew Lunn 788a4d56ff drivers: phy: Add support for optional phys
Add devm_phy_optional_get and phy_optional_get, which should be used
when the phy is optional. They does not return an error when the phy
does not exist, rather they returns NULL, which is considered as a valid
phy, but results in NOPs when used with the consumer API.

Andrew Lunn 04c2facad8 drivers: phy: Make NULL a valid phy reference
The common clock framework considers NULL a valid clock
reference. This makes handling optional clocks simple, in that if the
optional clock is not available, a NULL reference can be used in the
place of a real clock, simplifying the clock consumer.

Extend this concept to the phy consumer API. A NULL can be passed to
the release calls, the phy_init() and phy_exit() calls, and
phy_power_on() and phy_power_off() and a NOP is performed.

    from Ben Hutchings.

 6) Implement auto corking in TCP, from Eric Dumazet.  Basically, if we
    have a small send and a previous packet is already in the qdisc or
    device queue, defer until TX completion or we get more data.

 7) Allow userspace to manage ipv6 temporary addresses, from Jiri Pirko.

 8) Add a qdisc bypass option for AF_PACKET sockets, from Daniel
    Borkmann.

 9) Share IP header compression code between Bluetooth and IEEE802154
    layers, from Jukka Rissanen.

11) Allow packets to be captured on macvtap devices, from Vlad Yasevich.

12) Support tunneling in GRO layer, from Jerry Chu.

13) Allow bonding to be configured fully using netlink, from Scott
    Feldman.

14) Allow AF_PACKET users to obtain the VLAN TPID, just like they can
    already get the TCI.  From Atzm Watanabe.

15) New "Heavy Hitter" qdisc, from Terry Lam.

16) Significantly improve the IPSEC support in pktgen, from Fan Du.

17) Allow ipv4 tunnels to cache routes, just like sockets.  From Tom
    Herbert.

18) Add Proportional Integral Enhanced packet scheduler, from Vijay
    Subramanian.

19) Allow openvswitch to mmap'd netlink, from Thomas Graf.

20) Key TCP metrics blobs also by source address, not just destination
    address.  From Christoph Paasch.

21) Support 10G in generic phylib.  From Andy Fleming.

22) Try to short-circuit GRO flow compares using device provided RX
    hash, if provided.  From Tom Herbert.

The wireless and netfilter folks have been busy little bees too.

when we called dev_WARN().  I have changed it to WARN_ON() so that we
get a stack dump and can fix the caller.

The rest of this patch is just cleanup like returning directly instead
of having do-nothing gotos.  Using descriptive labels instead of
GW-BASIC style "err0" and "err1".  I also flipped the order of
put_device() and ida_remove() so they are a mirror reflection of the

PHY with or without using phandle. For dt-boot, the PHY drivers should
also register *PHY provider* with the framework.

PHY drivers should create the PHY by passing id and ops like init, exit,
power_on and power_off. This framework is also pm runtime enabled.
