2015-08-05spmi: Select IRQ_DOMAIN instead of depend on itStephen Boyd1-1/+1
IRQ_DOMAIN is a hidden config option, so depending on it doesn't make any sense. Select the config option because it's required to compile this driver.

2015-05-24spmi: Add dependency on HAS_IOMEMRichard Weinberger1-0/+1
Not all architectures have io memory. Fixes: drivers/built-in.o: In function `spmi_pmic_arb_probe': spmi-pmic-arb.c:(.text+0x1ed399): undefined reference to `devm_ioremap_resource' Signed-off-by: Richard Weinberger <richard@nod.at> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2015-04-03spmi: pmic_arb: remove ARM build time dependencyIvan T. Ivanov1-1/+0
Qualcomm PMIC arbiter driver already depends on ARCH_QCOM, which could be either ARM or ARM64. New version of the PMIC arbiter controller is available on 64 bit platforms. Remove ARM dependency to allow driver to be build for 64 bit platforms. Signed-off-by: Ivan T. Ivanov <ivan.ivanov@linaro.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2014-03-08spmi: pmic_arb: make selectable on ARCH_QCOMJosh Cartwright1-2/+2
With the split of Qualcomm MSM support into legacy and multiplatform, the SPMI PMIC arb driver is only relevant on the multiplatform supported SoCs. Switch the Kconfig depends to ARCH_QCOM.

2014-02-15spmi: pmic_arb: add support for interrupt handlingJosh Cartwright1-0/+1
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.

2014-02-15spmi: Add MSM PMIC Arbiter SPMI controllerKenneth Heitke1-0/+17
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.

2014-02-15spmi: Linux driver framework for SPMIKenneth Heitke1-0/+9
System Power Management Interface (SPMI) is a specification developed by the MIPI (Mobile Industry Process Interface) Alliance optimized for the real time control of Power Management ICs (PMIC). SPMI is a two-wire serial interface that supports up to 4 master devices and up to 16 logical slaves. The framework supports message APIs, multiple busses (1 controller per bus) and multiple clients/slave devices per controller.
