Subject: [PATCH v2 4/4] mmc: sdhci-tegra: Use actual clock rate for SW tuning correction
Date: Wed, 14 Sep 2022 15:26:28 +0530 [thread overview]
Message-ID: <20220914095628.26093-4-pshete@nvidia.com> (raw)
In-Reply-To: <20220914095628.26093-1-pshete@nvidia.com>
Ensure tegra_host member "curr_clk_rate" holds the actual clock rate
instead of requested clock rate for proper use during tuning correction
algorithm.
Fixes: ea8fc5953e8b ("mmc: tegra: update hw tuning process")
