* mmc: sdhci: return error when failed add_sdhci().Jaehoon Chung2013-05-061-2/+1

* mmc: sdhci: Add a quirk to add delay during completion of sdhci_send_cmdTushar Behera2012-10-221-1/+2
| | | | | | | | | | | | | | | | | MMC host controller requires a delay between every sdhci_send_cmd() execution. In s5p_mmc driver (s5p_sdhci replaces this driver), a delay of 1000us was provided after every mmc_send_cmd() call. Adding a quirk in current sdhci driver to replicate the behaviour. Without this delay, MMC initialization on Origen board fails with following error messages. Timeout for status update! mmc fail to send stop cmd Signed-off-by: Tushar Behera <tushar.behera@linaro.org> Signed-off-by: Jaehoon Chung <jh80.chung@samsung.com> Signed-off-by: Andy Fleming <afleming@freescale.com>

| | | | | | | | | | Useless code is removed, and get buswidth value. buswidth value will be used to choice the 4bit or 8bit.

* mmc: s5p_sdhci: set the SDHCI_QUIRK_BROKEN_R1BJaehoon Chung2012-09-051-6/+4
| | | | | | | | | | Samsung SoC is broken busy waiting for R1b type. And clk delay control value is modified the previosuly value.

* mmc: support the sdhci instead of s5p_mmc for samsung-socJaehoon Chung2012-05-081-0/+98
In driver mmc, generic s5p_sdhci code is implemented. s5p_mmc file is dupulicated. we are good that use the generic sdhci. This patch supported the sdhci for Samsung-SoC.
