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>
2018-04-27Remove unnecessary instances of DECLARE_GLOBAL_DATA_PTRTom Rini
We have a large number of places where while we historically referenced gd in the code we no longer do, as well as cases where the code added that line "just in case" during development and never dropped it. Signed-off-by: Tom Rini <trini@konsulko.com>

A typo in the probe function causes not all peripherals to be scanned (in the case of the Dragonboard820c - work in progress - it wont find pmic0).
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.

2016-08-12fdt: allow fdtdec_get_addr_size_*() to translate addressesStephen Warren
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.

Linux stopped the use of keyword 'boolean' in Kconfig. Refer to commit 6341e62b212a2541efb0160c470e90bd226d5496 ("kconfig: use bool instead of boolean for type definition attributes") in Linux Kernel. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2016-07-27dm: Use dm_scan_fdt_dev() directly where possibleSimon Glass
Quite a few places have a bind() method which just calls dm_scan_fdt_dev(). We may as well call dm_scan_fdt_dev() directly. Update the code to do this. Signed-off-by: Simon Glass <sjg@chromium.org>

This new function is more convenient for callers, and handles pre-relocation situations automatically. Signed-off-by: Simon Glass <sjg@chromium.org>

There is off-by-one error in sandbox_emul_gpio that causes segfault of certain tests. EMUL_GPIO_REG_END is the address of last valid (emulated) register. This patch fixed this (by adding one more element to emulated register array). Signed-off-by: Mateusz Kulikowski <mateusz.kulikowski@gmail.com> Tested-by: Stephen Warren <swarren@nvidia.com>

2016-04-01drivers: Add SPMI bus uclassMateusz Kulikowski
Qualcom processors use proprietary bus to talk with PMIC devices - SPMI (System Power Management Interface). On wiring level it is similar to I2C, but on protocol level, it's multi-master and has simple autodetection capabilities. This commit adds simple uclass that provides bus read/write interface.
