From f313936261ac18a2527fc0752cf988950587d0ce Mon Sep 17 00:00:00 2001 From: Arun Ramadoss Date: Fri, 2 Sep 2022 16:02:09 +0530 Subject: [PATCH] net: dsa: microchip: lan937x: clear the POR_READY_INT status bit In the lan937x_reset_switch(), it masks all the switch and port registers. In the Global_Int_status register, POR ready bit is write 1 to clear bit and all other bits are read only. So, this patch clear the por_ready_int status bit by writing 1.
