From d0003b5edf11b0fc2a050e2a0eaac39ba921d85e Mon Sep 17 00:00:00 2001 From: Ashok Reddy Soma Date: Wed, 24 Aug 2022 05:38:46 -0600 Subject: [PATCH] spi: cadence_qspi: Call read_setup for STIG_READ In cadence_spi_read_id we are using STIG mode to read flash id's. Call cadence_qspi_apb_command_read_setup() to setup cmd, addr and data bus width properly before cadence_qspi_apb_command_read().
