With the incremental patch below applied, Tested-by: Stephen Warren <swar...@nvidia.com> On: Harmony, Seaboard(really Springbank), Ventana, Whistler, Paz00/AC100, TrimSlice. > commit a5be5907d77eb4ca18dd9a11dd09183148c9d1b2 > Author: Stephen Warren <swar...@nvidia.com> > Date: Thu Feb 14 16:02:24 2013 -0700 > > Fix MMC DT rework > > diff --git a/drivers/mmc/tegra_mmc.c b/drivers/mmc/tegra_mmc.c > index e8e8512..630f6bd 100644 > --- a/drivers/mmc/tegra_mmc.c > +++ b/drivers/mmc/tegra_mmc.c > @@ -497,7 +497,6 @@ static int do_mmc_init(int dev_index) > struct mmc_host *host; > char gpusage[12]; /* "SD/MMCn PWR" or "SD/MMCn CD" */ > struct mmc *mmc; > - int card_det = 0; > > /* DT should have been read & host config filled in */ > host = &mmc_host[dev_index]; > @@ -514,16 +513,15 @@ static int do_mmc_init(int dev_index) > if (fdt_gpio_isvalid(&host->pwr_gpio)) { > sprintf(gpusage, "SD/MMC%d PWR", dev_index); > gpio_request(host->pwr_gpio.gpio, gpusage); > - fdtdec_set_gpio(&host->pwr_gpio, 1); > + gpio_direction_output(host->pwr_gpio.gpio, 1); > debug(" Power GPIO name = %s\n", host->pwr_gpio.name); > } > > if (fdt_gpio_isvalid(&host->cd_gpio)) { > sprintf(gpusage, "SD/MMC%d CD", dev_index); > gpio_request(host->cd_gpio.gpio, gpusage); > - card_det = fdtdec_get_gpio(&host->cd_gpio); > + gpio_direction_input(host->cd_gpio.gpio); > debug(" CD GPIO name = %s\n", host->cd_gpio.name); > - debug("%s: CD state = %d\n", __func__, card_det); > } > > mmc = &mmc_dev[dev_index]; _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
