net: phy: ti: rename ti.c to dp83867.c

2019-12-09T15:47:42+00:00

The driver ti.c is actually driver for TI DP83867x PHYs, so rename it
accordingly.

net: phy: ti: Fix clock output DT property

2019-07-15T18:32:25+00:00

The code block reading the DT property for the clock output control was
before the phy's DT node pointer was set, so it could never work.  Move
it after the node pointer is set.

Also store the unsigned 32-bit property into an unsigned value, not a
signed value, as the former will cause a problem if value overflows.
For instance, if one were to add 0xffffffff as a code to mean the clock
output should be turned off.

net: phy: ti: Use default values for tx/rx delay and fifo size

2019-07-15T18:32:25+00:00

When not using DM_ETH, these PHY settings are programmed with default
values hardcoded into the driver.  When using DM_ETH, they should come
from the device tree.  However, if the device tree does not have the
properties, the driver will silent use -1.  Which is entirely out of
range, programs nonsense into the PHY's registers, and does not work.

Change this to use the same defaults as non-DM_ETH if the device tree is
lacking the properties.

As an alternative, the kernel driver for the phy will display an error
message and fail if the device tree is lacking.

net: phy: ti: Add binding for the CLK_OUT pin muxing

2018-10-10T17:28:54+00:00

The DP83867 has a muxing option for the CLK_OUT pin. It is possible
to set CLK_OUT for different channels.
Create a binding to select a specific clock for CLK_OUT pin.

Based on commit 9708fb630d19 ("net: phy: dp83867: Add binding for
the CLK_OUT pin muxing option") of mainline linux kernel.

net: phy: ti: Recover from "port mirroring" N/A MODE4

2018-10-10T17:28:54+00:00

The DP83867 when not properly bootstrapped - especially with LED_0 pin -
can enter N/A MODE4 for "port mirroring" feature.

To provide normal operation of the PHY, one needs not only to explicitly
disable the port mirroring feature, but as well stop some IC internal
testing (which disables RGMII communication).

To do that the STRAP_STS1 (0x006E) register must be read and RESERVED bit
11 examined. When it is set, the another RESERVED bit (11) at PHYCR
(0x0010) register must be clear to disable testing mode and enable RGMII
communication.

Thorough explanation of the problem can be found at following e2e thread:
"DP83867IR: Problem with RESERVED bits in PHY Control Register (PHYCR) -
Linux driver"

net: phy: ti: Add lane swapping support in the DP83867 TI's PHY driver

2018-10-10T17:28:53+00:00

This patch adds support for enabling or disabling the lane swapping
(called "port mirroring" in PHY's CFG4 register) feature of the DP83867
TI's PHY device.

One use case is when bootstrap configuration enables this feature (because
of e.g. LED_0 wrong wiring) so then one needs to disable it in software
(at u-boot/Linux).

Based on commit fc6d39c39581 ("net: phy: dp83867: Add lane swapping
support in the DP83867 TI's PHY driver") of mainline linux kernel.
