2015-10-22drivers: Introduce a simplified remoteproc frameworkNishanth Menon
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.

2015-08-05dm: i2c: Add support for multiplexed I2C busesSimon Glass
Add a new I2C_MUX uclass. Devices in this class can multiplex between several I2C buses, selecting them one at a time for use by the system. The multiplexing mechanism is left to the driver to decide - it may be controlled by GPIOs, for example. The uclass supports only two methods: select() and deselect(). The current mux state is expected to be stored in the mux itself since it is the only thing that knows how to make things work. The mux can record the current state and then avoid switching unless it is necessary. So select() can be skipped if the mux is already in the correct state. Also deselect() can be made a nop if required. Signed-off-by: Simon Glass <sjg@chromium.org>

2015-06-05fdt: Pass the device serial number through devicetreePaul Kocialkowski
Before device-tree, the device serial number used to be passed to the kernel using ATAGs (on ARM). This is now deprecated and all the handover to the kernel should now be done using device-tree. Thus, this passes the serial-number property to the kernel using the serial-number property of the root node, as expected by the kernel. The serial number is a string that somewhat represents the device's serial number. It might come from some form of storage (e.g. an eeprom) and be programmed at factory-time by the manufacturer or come from identification bits available in e.g. the SoC.

2015-05-14sandbox: add: sandbox PMIC device drivers: I2C emul, pmic, regulatorPrzemyslaw Marczak
This commit adds emulation of sandbox PMIC device, which includes: - PMIC I2C emulation driver - PMIC I/O driver (UCLASS_PMIC) - PMIC regulator driver (UCLASS_REGULATOR) The sandbox PMIC has 12 significant registers and 4 as padding to 16 bytes, which allows using 'i2c md' command with the default count (16). The sandbox PMIC provides regulators: - 2x BUCK - 2x LDO Each, with adjustable output: - Enable state - Voltage - Current limit (LDO1/BUCK1 only) - Operation mode (different for BUCK and LDO) Each attribute has it's own register, beside the enable state, which depends on operation mode. The header file: sandbox_pmic.h includes PMIC's default register values, which are set on i2c pmic emul driver's probe() method.

2015-05-14dm: regulator: add fixed voltage regulator driverPrzemyslaw Marczak
This driver implements regulator operations for fixed Voltage/Current value regulators. beside the standard regulator constraints, which are put into the uclass platform data, a typical fixed regulator node provides few additional properties like: - gpio - gpio-open-drain - enable-active-high - startup-delay-us The only 'gpio' is used by this driver and is kept in structure of type 'fixed_regulator_platdata', as a device platform data (dev->platdata). The driver implements: - get_value - get_current - get_enable - set_enable The regulator calls and commands can be used for fixed-regulator devices, and the proper error will be returned for prohibited.

This is the implementation of driver model PMIC driver. The max77686 PMIC driver implements read/write operations and driver bind method - to bind its childs. This driver will try to bind the regulator devices by using it's child info array with regulator prefixes and driver names. This should succeed when compatible regulator driver is compiled. If no regulator driver found, then the pmic can still provide read/write operations, and can be used with PMIC function calls.
