* mmc: sdhci-bcm-kona: fix error return code in sdhci_bcm_kona_probe()Wei Yongjun2016-09-26
| | | | | | | | | | | In clk_set_rate() or clk_prepare_enable() error handling case, the error return code ret is not set, so sdhci_bcm_kona_probe() return 0 in those error cases.

* mmc: sdhci-pltfm: Drop define for SDHCI_PLTFM_PMOPSUlf Hansson2016-07-29
| | | | | | | Due to previous changes this define has no longer a purpose. Instead move the sdhci-pltfm drivers over to use the exported struct sdhci_pltfm_pmops. Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
* mmc: host: use the defined function to check whether card is removableJaehoon Chung2016-07-25
| | | | | | | | | In linux/mmc/host.h, mmc_card_is_removable() is already defined. It should be maintainted more easier than now. Signed-off-by: Jaehoon Chung <jh80.chung@samsung.com> Reviewed-by: Shawn Lin <shawn.lin@rock-chips.com> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
* mmc: sdhci-bcm-kona: fix logic to check for 8-bit data widthJavier Martinez Canillas2015-10-26
| | | | | | | | | | The driver prints if the data width is 8-bit but it's using a binary OR instead of a binary AND so it will always report as "is_8bit=Y" regardless of the flags in host->mmc->caps.

* mmc: sdhci: set the .remove to sdhci_pltfm_unregister()Kevin Hao2015-03-23
| | | | | | | | | In these drivers, the driver specific .remove function just a simple wrapper of function sdhci_pltfm_unregister(). So remove these wrappers and just set .remove to sdhci_pltfm_unregister(). Signed-off-by: Kevin Hao <haokexin@gmail.com> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>

* mmc: sdhci-bcm-kona: kill the "external_clk" member in driver private structKevin Hao2015-03-23
| | | | | | | | | | Actually we can use the "clk" in the struct sdhci_pltfm_host. Also change the "external clock" to "core clock" and kill two redundant private functions in this driver as suggested by Ray Jui.

* mmc, sdhci, bcm-kona, LLVMLinux: Remove use of __initconstBehan Webster2014-10-03
| | | | | | | | | | | | | The __initconst is in the wrong place, and when moved to the correct place it uncovers an error where the variable is used by non-init data structures. Instead merely make them const and put the const in the right spot.
