From cfeeea60af2f01c13b94d57a9bb1291e7bc181da Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Mon, 16 Nov 2020 12:57:13 +0200 Subject: bus: ti-sysc: Implement GPMC debug quirk to drop platform data We need to enable no-reset-on-init quirk for GPMC if the config option for CONFIG_OMAP_GPMC_DEBUG is set. Otherwise the GPMC driver code is unable to show the bootloader configured timings.
