We can use the dw_mci_exynos_priv_init to do some actual platform specific initialisation of SMU and etc. Signed-off-by: Yuvaraj Kumar C D --- drivers/mmc/host/dw_mmc-exynos.c | 31 +++++++++++++++---------------- 1 file changed, 15 insertions(+), 16 deletions(-) diff --git a/drivers/mmc/host/dw_mmc-exynos.c b/drivers/mmc/host/dw_mmc-exynos.c index 9990f98..19c845b 100644 --- a/drivers/mmc/host/dw_mmc-exynos.c +++ b/drivers/mmc/host/dw_mmc-exynos.c @@ -72,22 +72,8 @@ static struct dw_mci_exynos_compatible { static int dw_mci_exynos_priv_init(struct dw_mci *host) { - struct dw_mci_exynos_priv_data *priv; - int idx; - - priv = devm_kzalloc(host->dev, sizeof(*priv), GFP_KERNEL); - if (!priv) { - dev_err(host->dev, "mem alloc failed for private data\n"); - return -ENOMEM; - } - - for (idx = 0; idx < ARRAY_SIZE(exynos_compat); idx++) { - if (of_device_is_compatible(host->dev->of_node, - exynos_compat[idx].compatible)) - priv->ctrl_type = exynos_compat[idx].ctrl_type; - } + struct dw_mci_exynos_priv_data *priv = host->priv; - host->priv = priv; return 0; } @@ -177,12 +163,24 @@ static void dw_mci_exynos_set_ios(struct dw_mci *host, struct mmc_ios *ios) static int dw_mci_exynos_parse_dt(struct dw_mci *host) { - struct dw_mci_exynos_priv_data *priv = host->priv; + struct dw_mci_exynos_priv_data *priv; struct device_node *np = host->dev->of_node; u32 timing[2]; u32 div = 0; + int idx; int ret; + priv = devm_kzalloc(host->dev, sizeof(*priv), GFP_KERNEL); + if (!priv) { + dev_err(host->dev, "mem alloc failed for private data\n"); + return -ENOMEM; + } + + for (idx = 0; idx < ARRAY_SIZE(exynos_compat); idx++) { + if (of_device_is_compatible(np, exynos_compat[idx].compatible)) + priv->ctrl_type = exynos_compat[idx].ctrl_type; + } + of_property_read_u32(np, "samsung,dw-mshc-ciu-div", &div); priv->ciu_div = div; @@ -199,6 +197,7 @@ static int dw_mci_exynos_parse_dt(struct dw_mci *host) return ret; priv->ddr_timing = SDMMC_CLKSEL_TIMING(timing[0], timing[1], div); + host->priv = priv; return 0; }
