* Various Makefiles: Add SPDX-License-Identifier tagsTom Rini2015-11-10-0/+4
| | | | | | | | | | | After consulting with some of the SPDX team, the conclusion is that Makefiles are worth adding SPDX-License-Identifier tags too, and most of ours have one. This adds tags to ones that lack them and converts a few that had full (or in one case, very partial) license blobs into the equivalent tag.

* drivers: Introduce a simplified remoteproc frameworkNishanth Menon2015-10-22-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many System on Chip(SoC) solutions are complex with multiple processors on the same die dedicated to either general purpose of specialized functions. Many examples do exist in today's SoCs from various vendors. Typical examples are micro controllers such as an ARM M3/M0 doing a offload of specific function such as event integration or power management or controlling camera etc. Traditionally, the responsibility of loading up such a processor with a firmware and communication has been with a High Level Operating System(HLOS) such as Linux. However, there exists classes of products where Linux would need to expect services from such a processor or the delay of Linux and operating system being able to load up such a firmware is unacceptable. To address these needs, we need some minimal capability to load such a system and ensure it is started prior to an Operating System(Linux or any other) is started up. NOTE: This is NOT meant to be a solve-all solution, instead, it tries to address certain class of SoCs and products that need such a solution. A very simple model is introduced here as part of the initial support that supports microcontrollers with internal memory (no MMU, no execution from external memory, or specific image format needs). This basic framework can then (hopefully) be extensible to other complex SoC processor support as need be.

* pinctrl: add pin control uclass supportMasahiro Yamada2015-08-31-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This creates a new framework for handling of pin control devices, i.e. devices that control different aspects of package pins. This uclass handles pinmuxing and pin configuration; pinmuxing controls switching among silicon blocks that share certain physical pins, pin configuration handles electronic properties such as pin- biasing, load capacitance etc. This framework can support the same device tree bindings, but if you do not need full interface support, you can disable some features to reduce memory foot print. Typically around 1.5KB is necessary to include full-featured uclass support on ARM board (CONFIG_PINCTRL + CONFIG_PINCTRL_FULL + CONFIG_PINCTRL_GENERIC + CONFIG_PINCTRL_PINMUX), for example. We are often limited on code size for SPL. Besides, we still have many boards that do not support device tree configuration. The full pinctrl, which requires OF_CONTROL, does not make sense for those boards. So, this framework also has a Do-It-Yourself (let's say simple pinctrl) interface. With CONFIG_PINCTRL_FULL disabled, the uclass itself provides no systematic mechanism for identifying the peripheral device, applying pinctrl settings, etc. They must be done in each low-level driver. In return, you can save much memory footprint and it might be useful especially for SPL. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Acked-by: Simon Glass <sjg@chromium.org>

* dm: Add a clock uclassSimon Glass2015-07-21-0/+1
| | | | | | | | | | | | | | | | | | | | | | | Clocks are an important feature of platforms and have become increasing complex with time. Most modern SoCs have multiple PLLs and dozens of clock dividers which distribute clocks to on-chip peripherals. Some SoC implementations have a clock API which is private to that SoC family, e.g. Tegra and Exynos. This is useful but it would be better to have a common API that can be understood and used throughout U-Boot. Add a simple clock API as a starting point. It supports querying and setting the rate of a clock. Each clock is a device. To reduce memory and processing overhead the concept of peripheral clocks is provided. These do not need to be explicit devices - it is possible to write a driver that can adjust the I2C clock (for example) without an explicit I2C clock device. This can dramatically reduce the number of devices (and associated overhead) in a complex SoC. Clocks are referenced by a number, and it is expected that SoCs will define that numbering themselves via an enum. Signed-off-by: Simon Glass <sjg@chromium.org>
