2023-03-16net: phy: mxl-gpy: enhance delay time required by loopback disable functionXu Liang
GPY2xx devices need 3 seconds to fully switch out of loopback mode before it can safely re-enter loopback mode. Implement timeout mechanism to guarantee 3 seconds waited before re-enter loopback mode. Signed-off-by: Xu Liang <lxu@maxlinear.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2023-01-10net: phy: mxl-gpy: disable interrupts on GPY215 by defaultMichael Walle
The interrupts on the GPY215B and GPY215C are broken and the only viable fix is to disable them altogether. There is still the possibilty to opt-in via the device tree.

2022-12-07net: phy: mxl-gpy: add MDINT workaroundMichael Walle
At least the GPY215B and GPY215C has a bug where it is still driving the interrupt line (MDINT) even after the interrupt status register is read and its bits are cleared. This will cause an interrupt storm. Although the MDINT is multiplexed with a GPIO pin and theoretically we could switch the pinmux to GPIO input mode, this isn't possible because the access to this register will stall exactly as long as the interrupt line is asserted. We exploit this very fact and just read a random internal register in our interrupt handler. This way, it will be delayed until the external interrupt line is released and an interrupt storm is avoided. The internal register access via the mailbox was deduced by looking at the downstream PHY API because the datasheet doesn't mention any of this.

Now having a major and a minor number, also print the firmware in human readable form "major.minor". Still keep the 4-digit hexadecimal representation because that form is used in the firmware changelog documents. Also, drop the "release" string assuming that most common case, but make it clearer that the user is running a test version.
