Wolfram Sang	f271fbddfa	spmi: drop owner assignment from platform_drivers ... A platform_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Wolfram Sang <wsa@the-dreams.de>	2014-10-20 16:21:36 +02:00
Josh Cartwright	67b563f1f2	spmi: pmic_arb: add support for interrupt handling ... The Qualcomm PMIC Arbiter, in addition to being a basic SPMI controller, also implements interrupt handling for slave devices. Note, this is outside the scope of SPMI, as SPMI leaves interrupt handling completely unspecified. Extend the driver to provide a irq_chip implementation and chained irq handling which allows for these interrupts to be used.

Kenneth Heitke	39ae93e3a3	spmi: Add MSM PMIC Arbiter SPMI controller ... Qualcomm's PMIC Arbiter SPMI controller functions as a bus master and is used to communication with one or more PMIC (slave) devices on the SPMI bus. The PMIC Arbiter is actually a hardware wrapper around the SPMI controller that provides concurrent and autonomous PMIC access to various entities that need to communicate with the PMIC. The SPMI controller hardware handles all of the SPMI bus activity (bus arbitration, sequence start condition, transmission of frames, etc). This software driver uses the PMIC Arbiter register interface to initiate command sequences on the SPMI bus. The status register is read to determine when the command sequence has completed and whether or not it completed successfully.
