Subject: [PATCH 5/9] bus: ti-sysc: Implement GPMC debug quirk to drop platform data
Date: Mon, 26 Oct 2020 13:10:45 +0200 [thread overview]
Message-ID: <20201026111049.54835-6-tony@atomide.com> (raw)
In-Reply-To: <20201026111049.54835-1-tony@atomide.com>
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.
