2018-08-13mmc: socfpga: Add clock framework supportMarek Vasut
Add support for fetching the clock frequency both using the legacy method in case clock framework is disabled as well as via the clock framework if it is enabled. This allows for migration to the clock framework on platforms which supports it while not breaking legacy platforms. That said, the legacy method must be removed eventually.

2018-07-09mmc: dwmmc: socfpga: Add reset ctrl to driverLey Foon Tan
Add code to reset all reset signals as in mmc DT node. A reset property is an optional feature, so only print out a warning and do not fail if a reset property is not present. If a reset property is discovered, then use it to deassert, thus bringing the IP out of reset. Signed-off-by: Ley Foon Tan <ley.foon.tan@intel.com> Reviewed-by: Simon Glass <sjg@chromium.org>
2018-05-08dm: mmc: socfpga: call dwmci_probe()Patrick Bruenn
On a socfpga_cyclone5 based board the SD card, was never powered up. For other dw_mmc based SoCs dwmci_probe() is called in the platform specific probe(). It seems this call is missing for socfpga_dw_mmc. With this change DWMCI_PWREN is set by dmwci_init().

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
2018-03-05libfdt: move headers to <linux/libfdt.h> and <linux/libfdt_env.h>Masahiro Yamada
Thomas reported U-Boot failed to build host tools if libfdt-devel package is installed because tools include libfdt headers from /usr/include/ instead of using internal ones. This commit moves the header code: include/libfdt.h -> include/linux/libfdt.h include/libfdt_env.h -> include/linux/libfdt_env.h and replaces include directives: #include <libfdt.h> -> #include <linux/libfdt.h> #include <libfdt_env.h> -> #include <linux/libfdt_env.h> Reported-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com> Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2017-06-01dm: Rename dev_addr..() functionsSimon Glass
These support the flat device tree. We want to use the dev_read_..() prefix for functions that support both flat tree and live tree. So rename the existing functions to avoid confusion. In the end we will have: 1. dev_read_addr...() - works on devices, supports flat/live tree 2. devfdt_get_addr...() - current functions, flat tree only 3. of_get_address() etc. - new functions, live tree only All drivers will be written to use 1. That function will in turn call either 2 or 3 depending on whether the flat or live tree is in use. Note this involves changing some dead code - the imx_lpi2c.c file.

2017-02-08dm: core: Replace of_offset with accessorSimon Glass
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.
