Actual clk rate may not be the same as the requested clk frequency depending on the parent clock source set. Tuning correction algorithm depends on certain parameters which are sensitive to current clk rate. If the host clk is selected instead of the actual clock rate, tuning correction algorithm may end up applying invalid correction, which could result in errors Fixes: ea8fc5953e8b ("mmc: tegra: update hw tuning process") Signed-off-by: Aniruddha TVS Rao Signed-off-by: Prathamesh Shete Acked-by: Adrian Hunter Acked-by: Thierry Reding Cc: stable@vger.kernel.org Link: https://lore.kernel.org/r/20221006130622.22900-4-pshete@nvidia.com Signed-off-by: Ulf Hansson diff --git a/drivers/mmc/host/sdhci-tegra.c b/drivers/mmc/host/sdhci-tegra.c index 2d2d8260c681..413925bce0ca 100644 --- a/drivers/mmc/host/sdhci-tegra.c +++ b/drivers/mmc/host/sdhci-tegra.c @@ -773,7 +773,7 @@ static void tegra_sdhci_set_clock(struct sdhci_host *host, unsigned int clock) dev_err(dev, "failed to set clk rate to %luHz: %d\n", host_clk, err); - tegra_host->curr_clk_rate = host_clk; + tegra_host->curr_clk_rate = clk_get_rate(pltfm_host->clk); if (tegra_host->ddr_signaling) host->max_clk = host_clk; else
