* mmc: sdhci: Distinguish between base clock and maximum peripheral frequencyStefan Herbrechtsmeier2017-01-23-1/+3
| | | | | | | | | | The sdhci controller assumes that the base clock frequency is fully supported by the peripheral and doesn't support hardware limitations. The Linux kernel distinguishes between base clock (max_clk) of the host controller and maximum frequency (f_max) of the card interface. Use the same differentiation and allow the platform to constrain the peripheral interface. Signed-off-by: Stefan Herbrechtsmeier <stefan.herbrechtsmeier@weidmueller.com>
* mmc: sdhci: use the host version value in sdhci_setup_cfgJaehoon Chung2016-10-10-2/+0
| | | | | | | | "host->version" isn't a SoC specific value. It doesn't need to get in each SoC drivers. Signed-off-by: Jaehoon Chung <jh80.chung@samsung.com> Reviewed-by: Minkyu Kang <mk7.kang@samsung.com>
* mmc: squash lines for immediate returnMasahiro Yamada2016-09-23-6/+1
| | | | | | | | | | | | | | These functions can be much simpler by squashing lines for immediate return. For *_bind() callbacks, they will be a simple wrapper function of an upper-level bind API. For mmc_set_{boot_bus_width,part_conf}, they will be a wrapper of mmc_switch(). Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Reviewed-by: Jaehoon Chung <jh80.chung@samsung.com>

| | | | | | | | | We no longer need to set 'caps' as it's not passed to sdhci_setup_cfg anymore. Fixes: 14bed52d276a ("mmc: sdhci: remove the unnecessary arguments for sdhci_setup_cfg") Signed-off-by: Tom Rini <trini@konsulko.com>
* mmc: sdhci: remove the unnecessary arguments for sdhci_setup_cfgJaehoon Chung2016-08-05-4/+2
| | | | | | | | | | | | | | Some arguments don't need to pass to sdhci_setup_cfg. Generic variable can be used in sdhci_setup_cfg, and some arguments are already included in sdhci_host struct. It's enough that just pass the board specific things to sdhci_setup_cfg(). After removing the unnecessary arguments, it's more simpler than before. It doesn't consider "Version" and "Capabilities" anymore in each SoC driver. Signed-off-by: Jaehoon Chung <jh80.chung@samsung.com> Reviewed-by: Simon Glass <sjg@chromium.org>

| | | | | | | | | | | | | | Add quirk to disable high speed incase the high speed was broken.This solves the issue where the the controller is used in High Speed Mode and the the hold time requirement for the JEDEC/MMC 4.41 specification is NOT met. This timing issue is not on all boards and hence provided config option to enable it when required.

* of: clean up OF_CONTROL ifdef conditionalsMasahiro Yamada2015-08-18-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | We have flipped CONFIG_SPL_DISABLE_OF_CONTROL. We have cleansing devices, $(SPL_) and CONFIG_IS_ENABLED(), so we are ready to clear away the ugly logic in include/fdtdec.h: #ifdef CONFIG_OF_CONTROL # if defined(CONFIG_SPL_BUILD) && !defined(SPL_OF_CONTROL) # define OF_CONTROL 0 # else # define OF_CONTROL 1 # endif #else # define OF_CONTROL 0 #endif Now CONFIG_IS_ENABLED(OF_CONTROL) is the substitute. It refers to CONFIG_OF_CONTROL for U-boot proper and CONFIG_SPL_OF_CONTROL for SPL. Also, we no longer have to cancel CONFIG_OF_CONTROL in include/config_uncmd_spl.h and scripts/Makefile.spl.
