Backport merged upstream patch that adds support for firmware loader from NVMEM or attached filesystem for Aquantia PHYs. Refresh all kernel patches affected by this change. Also update the path for aquantia .ko that got moved to dedicated directory upstream. Signed-off-by: Christian Marangi <ansuelsmth@gmail.com>

Subject: [PATCH] net: phy: add Motorcomm YT8531S phy id.
|
|
|
|
We added patch for motorcomm.c to support YT8531S. This patch has
|
|
been tested on AM335x platform which has one YT8531S interface
|
|
card and passed all test cases.
|
|
The tested cases indluding: YT8531S UTP function with support of
|
|
10M/100M/1000M; YT8531S Fiber function with support of 100M/1000M;
|
|
and YT8531S Combo function that supports auto detection of media type.
|
|
|
|
Since most functions of YT8531S are similar to YT8521 and we reuse some
|
|
codes for YT8521 in the patch file.
