* dm: core: Replace of_offset with accessorSimon Glass2017-02-08-1/+1
| | | | | | | | | At present devices use a simple integer offset to record the device tree node associated with the device. In preparation for supporting a live device tree, which uses a node pointer instead, refactor existing code to access this field through an inline function.

* mmc: sdhci: Distinguish between base clock and maximum peripheral frequencyStefan Herbrechtsmeier2017-01-23-2/+2
| | | | | | | | | | 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: 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>
* mmc: sdhci: remove the unnecessary arguments for sdhci_setup_cfgJaehoon Chung2016-08-05-6/+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>
* mmc: rockchip: add SDHCI driver support for rockchip socKever Yang2016-07-25-0/+93
Rockchip rk3399 using arasan sdhci-5.1 controller. This patch add the controller support to enable mmc device with full driver-model support, tested on rk3399 evb board. According to my test result, this driver should be OK, the command "part list mmc 0" can result in a right output, but all the mmc command failed like this: => mmc info No MMC device available Command failed, result=1 The result of get_mmc_num in cmd/mmc.c is always 0?
