From 7c49bd50ed16644f46cac5ea711890efe49e2984 Mon Sep 17 00:00:00 2001 From: Aleksandar Gerasimovski Date: Tue, 16 Nov 2021 12:48:46 +0000 Subject: km: qrio: add function to read SLFTEST pin status There is a request from HW designers to use this QRIO pin for detecting DIC26_SELFTEST status instead of a GPIO pin. This pin is typically used during production for executing POST tests and starting test ESW bank.
