      net: phy: remove calls to genphy_config_init · c227ce44
      由 Heiner Kallweit 提交于 
      Supported PHY features are either auto-detected or explicitly set.
In both cases calling genphy_config_init isn't needed. All that
genphy_config_init does is removing features that are set as
supported but can't be auto-detected. Basically it duplicates the
code in genphy_read_abilities. Therefore remove such calls from
all PHY drivers.

v2:
- remove call also from new adin PHY driver
v3:
- pass NULL as config_init function pointer for dp83848

      net: phy: mscc: add support for VSC8514 PHY. · e4f9ba64
      由 Kavya Sree Kotagiri 提交于 
      The VSC8514 PHY is a 4-ports PHY that is 10/100/1000BASE-T, 100BASE-FX,
1000BASE-X, can communicate with the MAC via QSGMII.
The MAC interface protocol for each port within QSGMII can
be either 1000BASE-X or SGMII, if the QSGMII MAC that the VSC8514 is
connecting to supports this functionality.
VSC8514 also supports SGMII MAC-side autonegotiation on each individual
port, downshifting, can set the blinking pattern of each of its 4 LEDs,
SyncE, 1000BASE-T Ring Resiliency as well as HP Auto-MDIX detection.

This adds support for 10BASE-T, 100BASE-TX, and 1000BASE-T,
QSGMII link with the MAC, downshifting, HP Auto-MDIX detection
and blinking pattern for its 4 LEDs.

The GPIO register bank is a set of registers that are common to all PHYs
in the package. So any modification in any register of this bank affects
all PHYs of the package.

If the PHYs haven't been reset before booting the Linux kernel and were
configured to use interrupts for e.g. link status updates, it is
required to clear the interrupts mask register of all PHYs before being
able to use interrupts with any PHY. The first PHY of the package that
will be init will take care of clearing all PHYs interrupts mask
registers. Thus, we need to keep track of the init sequence in the
package, if it's already been done or if it's to be done.

Most of the init sequence of a PHY of the package is common to all PHYs
in the package, thus we use the SMI broadcast feature which enables us
to propagate a write in one register of one PHY to all PHYs in the same
package.

      net: phy: mscc: add support for VSC8574 PHY · 00d70d8e
      由 Quentin Schulz 提交于 
      The VSC8574 PHY is a 4-ports PHY that is 10/100/1000BASE-T, 100BASE-FX,
1000BASE-X and triple-speed copper SFP capable, can communicate with
the MAC via SGMII, QSGMII or 1000BASE-X, supports WOL, downshifting and
can set the blinking pattern of each of its 4 LEDs, supports SyncE as
well as HP Auto-MDIX detection.

This adds support for 10/100/1000BASE-T, SGMII/QSGMII link with the MAC,
WOL, downshifting, HP Auto-MDIX detection and blinking pattern for its 4
LEDs.

The VSC8574 has also an internal Intel 8051 microcontroller whose
firmware needs to be patched when the PHY is reset. If the 8051's
firmware has the expected CRC, its patching can be skipped. The
microcontroller can be accessed from any port of the PHY, though the CRC
function can only be done through the PHY that is the base PHY of the
package (internal address 0) due to a limitation of the firmware.

The revA of the VSC8584 PHY (which is not and will not be publicly
released) should NOT patch the firmware of the microcontroller or it'll
make things worse, the easiest way is just to not support it.

      由 Quentin Schulz 提交于 
      Here, the rc variable is either used only for the condition right after
the assignment or right before being used as the return value of the
function it's being used in.

So let's remove this unneeded temporary variable whenever possible.

      由 Quentin Schulz 提交于 
      `if (x != 0)` is basically a more verbose version of `if (x)` so let's
use the latter so it's consistent throughout the whole driver.

      net: phy: mscc: remove unneeded parenthesis · b7d373c5
      由 Quentin Schulz 提交于 
      The == operator precedes the || operator, so we can remove the
parenthesis around (a == b) || (c == d).

The condition is rather explicit and short so removing the parenthesis
definitely does not make it harder to read.

      net: phy: mscc: Add EEE init sequence · 96dae01f
      由 Raju Lakkaraju 提交于 
      Microsemi PHYs (VSC 8530/31/40/41) need to update the Energy Efficient
Ethernet initialization sequence.
In order to avoid certain link state errors that could result in link
drops and packet loss, the physical coding sublayer (PCS) must be
updated with settings related to EEE in order to improve performance.
