i2c: Introduce QMSI I2C driver This patch introduces the QMSI I2C driver which is simply a shim driver based on I2C driver provided by QMSI BSP. This initial version supports only I2C_0 controller in 'master' mode. Due to some issues with qm_i2c_master_irq_transfer API, the driver uses the polling APIs from QMSI. This means that the current thread doesn't sleep (i.e. is not scheduled out) while the I2C transfer is carried out. The qm_i2c_master_irq_transfer() issue is under investigation. Below follows the missing features which will be addressed by a new version of this patch or by upcoming patches. * Block the current thread until the I2C operation has actually completed. * Add support for multiple controllers. * Add support for slave mode. * Add support for suspend() and resume() APIs. In order to enable this driver, the following options should be set: CONFIG_QMSI_DRIVERS=y CONFIG_QMSI_INSTALL_PATH="/path/to/libqmsi/directory" CONFIG_I2C=y CONFIG_I2C_QMSI=y Finally, due to the lack of proper support for Quark SE in QMSI 1.0.0, this driver requires QMSI version greater than 1.0.0. This driver has been tested only with Quark SE based boards. Change-Id: I369992c7b5fe37f7e0b45be7f19e667ad1fca9ac Signed-off-by: Andre Guedes <andre.guedes@intel.com>

interrupts: new static IRQ API The interrupt API has been redesigned: - irq_connect() for dynamic interrupts renamed to irq_connect_dynamic(). It will be used in situations where the new static irq_connect() won't work, i.e. the value of arguments can't be computed at build time - a new API for static interrupts replaces irq_connect(). it is used exactly the same way as its dynamic counterpart. The old static irq macros will be removed - Separate stub assembly files are no longer needed as the stubs are now generated inline with irq_connect() ReST documentation updated for the changed API. Some detail about the IDT in ROM added, and an oblique reference to the internal-only _irq_handler_set() API removed; we don't talk about internal APIs in the official documentation.

i2c: Add I2C driver for Quark SE Sensor Subsystem This adds the I2C driver for the Sensor Subsystem on Quark SE. This provides minimal support for the I2C controller, and does only synchronous transfer at the moment.

i2c: adds driver for Atmel SAM3 Adds the driver to utilize the I2C/TWI interface on Atmel SAM3 family processors for I2C communication. Note that this currently only supports master mode. Limited testing has been done using the Fujitsu FRAM sample app. Change-Id: Ibdb8277e47dd9450b49a66a95421eb1ffb1c4eb4 Signed-off-by: Daniel Leung <daniel.leung@intel.com>
