Yes, previous patch series also had new compatible which introduced new mux DT properties in atmel-flexcom.yaml and mux driver.
As part of review comments from Peter Rosin on driver part, Mux implementation is dropped. Please ignore previous patch series. Now, flexcom chip-select support is done in atme-flexcom.c driver. So, I started new patch series now which introduced new DT properties "microchip,flx-shrd-pins" and "microchip,flx-cs-names" and driver changes only in atmel-flexcom.c driver.
