Qualcomm SSDK is driver for Qualcomm Atheros switches and PHY-s. It is quite complicated and used by rest of the Qualcomm SDK stack for anything switch or PHY related. It is required for IPQ807x support as currently, there is no better driver for the built-in switch or UNIPHY. So, lets add the fixed-up version that supports kernel 5.15 for use on ipq807x target until a better driver is available.

Subject: [PATCH 03/11] SSDK: platform: use of_mdio_find_bus() to get MDIO bus
|
|
|
|
Kernel has a generic of_mdio_find_bus() which can get the appropriate
|
|
MDIO bus based on the DT node.
|
|
So, drop the getting MDIO from platform data, which no longer works
|
|
in 5.4 and later and use of_mdio_find_bus().
