* dm: x86: Create a driver for x86 interruptsSimon Glass2016-01-24-0/+1
| | | | | | | | | | | | | | | | It seems likely that at some point we will want a generic interrupt uclass. But this is a big undertaking as it involves unifying code across multiple architectures. As a first step, create a simple IRQ uclass and a driver for x86. This can be generalised later as required. Adjust pirq_init() to probe this driver, which has the effect of creating routing tables and setting up the interrupt routing. This is a start towards making interrupts fit better with driver model.

* dm: pinctrl: Add a way for a GPIO driver to obtain a pin functionSimon Glass2016-01-21-0/+32
| | | | | | | | | | | | | GPIO drivers want to be able to show if a pin is enabled for input, output, or is being used by another function. Some drivers can easily find this and the code is included in the driver. For some SoCs this is more complex. Conceptually this should be handled by pinctrl rather than GPIO. Most pinctrl drivers will have this feature anyway. Add a method by which a GPIO driver can obtain the pin mux value given a GPIO reference. This avoids repeating the code in two places.

| | | | | | | | | | | | The existing LCD/video interface suffers from conflating the bitmap display with text output on that display.

* dm: video: Add a video uclassSimon Glass2016-01-20-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | U-Boot has separate code for LCDs and 'video' devices. Both now use a very similar API thanks to earlier work by Nikita Kiryanov. With the driver- model conversion we should unify these into a single uclass. Unfortunately there are different features supported by each. This implementation provides for a common set of features which should serve most purposes. The intent is to support: - bitmap devices with 8, 16 and 32 bits per pixel - text console wih white on black or vice versa - rotated text console - bitmap display (BMP format) More can be added as additional boards are ported over to use driver model for video. The name 'video' is chosen for the uclass since it is more generic than LCD. Another option would be 'display' but that would introduce a third concept to U-Boot which seems like the wrong approach. The existing LCD and video init functions are not needed now, so this uclass makes no attempt to implement them.

* 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 the concept of peripheral IDsSimon Glass2015-09-02-0/+60
| | | | | | | | | | | | | | | | | | | | | | | | | My original pinctrl patch operating using a peripheral ID enum. This was shared between pinmux and clock and provides an easy way to specify a device that needs to be controlled, even it is does not (yet) have a driver within driver model. Masahiro's new simple pinctrl gets around this by providing a set_state_simple() pinctrl method. By passing a device to that call the peripheral ID becomes unnecessary. If the driver needs it, it can calculate it itself and use it internally. However this does not solve the problem for peripheral clocks. The 'pure' solution would be to pass a driver to the clock uclass also. But this requires that all devices should have a driver, and a struct udevide. Also a key optimisation of the clock uclass is allowing a peripheral clock to be set even when there is no device for that clock. There may be a better way to achive the same goal, but for now it seems expedient to add in peripheral ID to the pinctrl uclass. Two methods are added - one to get the peripheral ID and one to select it. The existing set_state_simple() is effectively the union of these. Signed-off-by: Simon Glass <sjg@chromium.org>
* pinctrl: add pin control uclass supportMasahiro Yamada2015-08-31-0/+229
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
