* dm: core: Replace of_offset with accessorSimon Glass2017-02-08-11/+8
| | | | | | | | | 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 Herbrechtsmeier2017-01-23-0/+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: sdhci: use the host version value in sdhci_setup_cfgJaehoon Chung2016-10-10-3/+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>
* fdt: allow fdtdec_get_addr_size_*() to translate addressesStephen Warren2016-08-12-1/+2
| | | | | | | | | | | | | | | Some code may want to read reg values from DT, but from nodes that aren't associated with DM devices, so using dev_get_addr_index() isn't appropriate. In this case, fdtdec_get_addr_size_*() are the functions to use. However, "translation" (via the chain of ranges properties in parent nodes) may still be desirable. Add a function parameter to request that, and implement it. Update all call sites to default to the original behaviour.

* mmc: sdhci: remove the unnecessary arguments for sdhci_setup_cfgJaehoon Chung2016-08-05-3/+1
| | | | | | | | | | | | | | 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>

* clk: convert API to match reset/mailbox styleStephen Warren2016-06-19-3/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The following changes are made to the clock API: * The concept of "clocks" and "peripheral clocks" are unified; each clock provider now implements a single set of clocks. This provides a simpler conceptual interface to clients, and better aligns with device tree clock bindings. * Clocks are now identified with a single "struct clk", rather than requiring clients to store the clock provider device and clock identity values separately. For simple clock consumers, this isolates clients from internal details of the clock API. * clk.h is split so it only contains the client/consumer API, whereas clk-uclass.h contains the provider API. This aligns with the recently added reset and mailbox APIs. * clk_ops .of_xlate(), .request(), and .free() are added so providers can customize these operations if needed. This also aligns with the recently added reset and mailbox APIs. * clk_disable() is added. * All users of the current clock APIs are updated. * Sandbox clock tests are updated to exercise clock lookup via DT, and clock enable/disable. * rkclk_get_clk() is removed and replaced with standard APIs. Buildman shows no clock-related errors for any board for which buildman can download a toolchain. test/py passes for sandbox (which invokes the dm clk test amongst others).

* mmc: Add support for Qualcomm SDHCI controllerMateusz Kulikowski2016-04-01-0/+180
Add support for SD/eMMC controller present on some Qualcomm Snapdragon devices. This controller implements SDHCI 2.0 interface but requires vendor-specific initialization. Driver works in PIO mode as ADMA is not supported by U-Boot (yet).
