* mfd: Add support for Qualcomm SPMI PMICsJosh Cartwright2014-09-261-0/+15
| | | | | | | | | | | | The Qualcomm SPMI PMIC chips are components used with the Snapdragon 800 series SoC family. This driver exists largely as a glue mfd component, it exists to be an owner of an SPMI regmap for children devices described in device tree.

* mfd: Add HI6421 PMIC Core driverGuodong Xu2014-09-261-0/+13
| | | | | | | | | | | | | | This adds driver to support HiSilicon Hi6421 PMIC. Hi6421 includes multi- functions, such as regulators, codec, ADCs, Coulomb counter, etc. This driver includes core APIs _only_. Drivers for individul components, like voltage regulators, are implemented in corresponding driver directories and files. Registers in Hi6421 are memory mapped, so using regmap-mmio API.

The chipsets have same MUIC component so the extcon, charger and regulators are almost the same. The MAX77836 however has also PMIC and Fuel Gauge. The MAX77836 uses three I2C slave addresses and has additional interrupts (related to PMIC and Fuel Gauge). It has also Interrupt Source register, just like MAX77686 and MAX77693. The MAX77836 PMIC's TOPSYS and INTSRC interrupts are reported in the PMIC block. The PMIC block has different I2C slave address and uses own regmap so another regmap_irq_chip is needed. Since we have two regmap_irq_chip, use shared interrupts on MAX77836. This patch adds additional defines and functions to the max14577 MFD core driver so the driver will handle both chipsets. Also this patch replaces "0x1 << N" with BIT(N) in defines for register masks.

* | mfd: pm8xxx: Move pm8xxx-irq.c contents into only driver that uses itStephen Boyd2014-03-191-10/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The pm8xxx-irq.c code is practically mandatory given that the pm8921-core driver will WARN about it missing and the Kconfig marks it as default y when a PM8xxx chips is enabled. The only reason the file was split out was because we planned to support other pm8xxx chips with different pm8xxx-core.c files. Now that we have DT on ARM this isn't necessary because we should be able to support all the ssbi based PM8xxx chips in one driver and one file with no data bloat. Let's move this code into the only driver that uses it right now (pm8921) so that it's always compiled when needed. In the future we can rename pm8921-core.c to something more generic.

* mfd: Add LP3943 MFD driverMilo Kim2014-01-211-0/+11
| | | | | | | | | | | | | | | | | | | | | LP3943 has 16 output pins which can be used as GPIO expander and PWM generator. * Regmap I2C interface for R/W LP3943 registers * Atomic operations for output pin assignment The driver should check whether requested pin is available or not. If the pin is already used, pin request returns as a failure. A driver data, 'pin_used' is checked when gpio_request() and pwm_request() are called. If the pin is available, then pin_used is set. And it is cleared when gpio_free() and pwm_free(). * Device tree support Compatible strings for GPIO and PWM driver. LP3943 platform data is PWM related, so parsing the device tree is implemented in the PWM driver. Signed-off-by: Milo Kim <milo.kim@ti.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
