Subject: [PATCH v8 12/26] memory: tegra124-emc: Continue probing if timings are missing in device-tree
Date: Wed, 11 Nov 2020 04:14:42 +0300 [thread overview]
Message-ID: <20201111011456.7875-13-digetx@gmail.com> (raw)
In-Reply-To: <20201111011456.7875-1-digetx@gmail.com>
EMC driver will become mandatory after turning it into interconnect
provider because interconnect users, like display controller driver, will
fail to probe using newer device-trees that have interconnect properties.
Thus make EMC driver to probe even if timings are missing in device-tree.
