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 06/11] qca8081: convert to 5.11 IRQ model
|
|
|
|
Kernel 5.11 introduced new IRQ handling model for PHY-s,
|
|
so provide those if 5.11 or later is used.
