Subject: [PATCH 02/10] net: phy: add support for scanning PHY in PHY packages
nodes
Add support for scanning PHY in PHY package nodes. PHY packages nodes
are just container for actual PHY on the MDIO bus.
Their PHY address defined in the PHY package node are absolute and
reflect the address on the MDIO bus.
mdio_bus.c and of_mdio.c is updated to now support and parse also
PHY package subnode by checking if the node name match
"ethernet-phy-package".
As PHY package reg is mandatory and each PHY in the PHY package must
have a reg, every invalid PHY Package node is ignored and will be
skipped by the autoscan fallback.

Subject: [PATCH 03/10] net: phy: add devm/of_phy_package_join helper
Add devm/of_phy_package_join helper to join PHYs in a PHY package. These
are variant of the manual phy_package_join with the difference that
these will use DT nodes to derive the base_addr instead of manually
passing an hardcoded value.
An additional value is added in phy_package_shared, "np" to reference
the PHY package node pointer in specific PHY driver probe_once and
config_init_once functions to make use of additional specific properties
defined in the PHY package node in DT.
The np value is filled only with of_phy_package_join if a valid PHY
package node is found. A valid PHY package node must have the node name
set to "ethernet-phy-package".

new PHY Family qca807x that will make use of both functions from at803x
and qca808x as it's a transition PHY with some implementation of at803x
and some from the new qca808x.

Subject: [PATCH 06/10] net: phy: provide whether link has changed in
c37_read_status
Some PHY driver might require additional regs call after
genphy_c37_read_status() is called.
Expand genphy_c37_read_status to provide a bool wheather the link has
changed or not to permit PHY driver to skip additional regs call if
nothing has changed.
Every user of genphy_c37_read_status() is updated with the new
additional bool.

From d1cb613efbd3cd7d0c000167816beb3f248f5eb8 Mon Sep 17 00:00:00 2001
From: Robert Marko <robert.marko@sartura.hr>

Subject: [PATCH 07/10] net: phy: qcom: add support for QCA807x PHY Family
This adds driver for the Qualcomm QCA8072 and QCA8075 PHY-s.
They are 2 or 5 port IEEE 802.3 clause 22 compliant 10BASE-Te,
100BASE-TX and 1000BASE-T PHY-s.
They feature 2 SerDes, one for PSGMII or QSGMII connection with
MAC, while second one is SGMII for connection to MAC or fiber.
Both models have a combo port that supports 1000BASE-X and
100BASE-FX fiber.
PHY package can be configured in 3 mode following this table:
First Serdes mode Second Serdes mode
Option 1 PSGMII for copper Disabled
ports 0-4
Option 2 PSGMII for copper 1000BASE-X / 100BASE-FX
ports 0-4
Option 3 QSGMII for copper SGMII for
ports 0-3 copper port 4
Each PHY inside of QCA807x series has 4 digitally controlled
output only pins that natively drive LED-s.
But some vendors used these to driver generic LED-s controlled
by userspace, so lets enable registering each PHY as GPIO
controller and add driver for it.
These are commonly used in Qualcomm IPQ40xx, IPQ60xx and IPQ807x
boards.

Subject: [PATCH 08/10] net: phy: qcom: move common qca808x LED define to
shared header
The LED implementation of qca808x and qca807x is the same but qca807x
supports also Fiber port and have different hw control bits for Fiber
port.
In preparation for qca807x introduction, move all the common define to
shared header.

Subject: [PATCH 09/10] net: phy: qcom: generalize some qca808x LED functions
Generalize some qca808x LED functions in preparation for qca807x LED
support.
The LED implementation of qca808x and qca807x is the same but qca807x
supports also Fiber port and have different hw control bits for Fiber
port. To limit code duplication introduce micro functions that takes reg
instead of LED index to tweak all the supported LED modes.

From f508a226b517a6a8afd78a317de46bc83e3e3d51 Mon Sep 17 00:00:00 2001

Subject: [PATCH 10/10] net: phy: qca807x: add support for configurable LED
QCA8072/5 have up to 2 LEDs attached for PHY.
LEDs can be configured to be ON/hw blink or be set to HW control.
Hw blink mode is set to blink at 4Hz or 250ms.
PHY can support both copper (TP) or fiber (FIBRE) kind and supports
different HW control modes based on the port type.
HW control modes supported for netdev trigger for copper ports are:
- LINK_10
- LINK_100
- LINK_1000
- TX
- RX
- FULL_DUPLEX
- HALF_DUPLEX
HW control modes supported for netdev trigger for fiber ports are:
- LINK_100
- LINK_1000
- TX
- RX
- FULL_DUPLEX
- HALF_DUPLEX
LED support conflicts with GPIO controller feature and must be disabled
if gpio-controller is used for the PHY.
