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>

2017-09-29mmc: sdhci-cadence: set timing mode register depending on frequencyMasahiro Yamada
The MMC framework in U-Boot does not support a systematic API for timing switch like mmc_set_timing() in Linux. U-Boot just provides a hook to change the clock frequency via mmc_set_clock(). It is up to drivers if additional register settings are needed. This driver needs to set a correct timing mode into a register when it migrates to a different speed mode. Only increasing clock frequency could result in setup/hold timing violation. The timing mode should be decided by checking MMC_TIMING_* like drivers/mmc/host/sdhci-cadence.c in Linux, but "timing" is not supported by U-Boot for now. Just use mmc->clock to decide the timing mode. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2017-07-19mmc: cadence: use fdt32_t for DT property value to fix sparse warningMasahiro Yamada
DTB is encoded in big endian. When we retrieve property values, we need to use fdt32_to_cpu (aka be32_to_cpu) for endian conversion. This is a bit error-prone, but sparse is useful to detect endian mismatch. We need to use (fdt32_t *) instead of (u32 *) for a pointer of a property value. Otherwise sparse warns "cast to restricted __be32". Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Signed-off-by: Jaehoon Chung <jh80.chung@samsung.com>
2017-06-01dm: core: Replace of_offset with accessor (part 2)Simon 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.

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.

2017-05-15mmc: sdhci-cadence: import updates from Linux 4.12Masahiro Yamada
This driver is a counterpart of drivers/mmc/host/sdhci-cadence.c from Linux. Some updates for v4.12-rc1 can be imported to U-Boot. - Fix value of SDHCI_CDNS_HRS04_RDATA_SHIFT - Add polling for ACK bit to be sure that data are written to the PHY register - Retrieve PHY values from DT properties instead of fixed data The following is the list of upstream commits: - Linux commit 4e03f628b464e0580abadf5161eaa38c61d20943 mmc: sdhci-cadence: fix bit shift of read data from PHY port - Linux commit a0f8243229ed071c8da0ea7cedc1b7bf1b1515da mmc: sdhci-cadence: Fix writing PHY delay - Linux commit a89c472d8b55c5afc4c79e6e3d1338730034eb01 mmc: sdhci-cadence: Update PHY delay configuration Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
