[PATCH v2 0/3] net: stmmac: socfpga: support both stmmaceth-ocp and ahb reset names

[Dinh Nguyen]

The dwmac-socfpga stmmac ethernet controller supports 2 standard reset
lines, named "stmmaceth" and "stmmaceth-ocp". At the time of upstreaming
support for the platform, the "stmmaceth-ocp" name was used for the 2nd
reset name. We later realized that the "stmmaceth-ocp" reset name is
the same as the "ahb" name that is used by the standard stmmac driver.
But since the "stmmaceth-ocp" name support has already been introduced
to the wild, it cannot just be removed from the driver, thus we can
modify the driver to support both "stmmaceth-ocp" and "ahb", with the
idea that "ahb" will be used going forward.

This series add the support to call reset assert/de-assert both "abh"
and "stmmaceth-ocp" to the dwmac-socfpga platform driver, then reverts
the patch that uses the DTS "stmmaceth-ocp" reset name.

[PATCH v2 1/3] net: stmmac: socfpga: add call to assert/deassert ahb reset line

[Dinh Nguyen]

The "stmmaceth-ocp" reset line of stmmac controller on the SoCFPGA
platform is essentially the "ahb" reset on the standard stmmac
controller. But since stmmaceth-ocp has already been introduced into
the wild, we cannot just remove support for it. But what we can do is
to support both "stmmaceth-ocp" and "ahb" reset names. Going forward we
will be using "ahb", but in order to not break ABI, we will be call reset
assert/de-assert both ahb and stmmaceth-ocp.

The ethernet hardware on SoCFPGA requires either the stmmaceth-ocp or
ahb reset to be asserted every time before changing the phy mode, then
de-asserted when the phy mode has been set.

With this change, we should be able to revert patch:
commit 62a40a0d5634 ("arm: dts: socfpga: use reset-name "stmmaceth-ocp"
instead of "ahb"")

[PATCH v2 2/3] Revert "arm: dts: socfpga: use reset-name "stmmaceth-ocp" instead of "ahb""

[Dinh Nguyen]

This reverts commit 62a40a0d5634834790f7166ab592be247390d857.

With the patch "add call to assert/deassert ahb reset line" in place, we can
safely remove the "stmmaceth-ocp" reset name and just use the standard
"ahb" reset name.
