* | mfd: qcom-i2c-pmic: add option to skip irq controlNicholas Troast2016-07-11
| | | | | | | | | | | | | | | | | | | | | | | | Some MFD PMIC configurations do not support interrupts. Make the interrupt controller optional to support these PMIC configrations. Without an interrupt controller this driver simply passes a regmap to its children.

* | mfd: wcd9xxx-irq: check if wcd9xxx_res irq is 0 before using itMeng Wang2016-07-08
| | | | | | | | | | | | | | | | | | | | | | During SSR, wcd9xxx_res irq lock is destroyed as part of resource cleanup. If driver tries to access wcd9xxx_res irq lock before it's initialized, it could cause crash. Check if wcd9xxx_res irq is 0 before using it to avoid crash.

* | mfd: introduce I2C PMIC controllerNicholas Troast2016-06-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The I2C PMIC Controller is used by multi-function PMIC devices which communicate over the I2C bus. The controller enumerates all child nodes as platform devices, and instantiates a regmap interface for them to communicate over the I2C bus. The controller also controls interrupts for all of the children platform devices. The controller handles the summary interrupt by deciphering which peripheral triggered the interrupt, and which of the peripheral interrupts were triggered. Finally, it calls the interrupt handlers for each of the virtual interrupts that were registered.

| | | | | | | | | | | | | | | | | | | | | | WCD and WSA codecs uses MSM gpios that are accessed through pinctrl mechanism. Codec reset gpios need to be configured before master controller is initialized otherwise codec cannot be enumerated on the bus. Add a new platform device driver to update reset gpio configuration to valid state before bus initialization.

All the spmi devices, marked by spmi-dev-container, become platform devices. spmi-slave-container devices become spmi_devices each representing a slave. The read/write functions use regmap api's instead of calls to spmi_ext_register_read/write() implemented by the spmi bus. This regmap is instantiated per slave. The spmi bus helper functions like spmi_get_irq get changed to their platform bus equivalents. Change Kconfig files include * Remove dependence on OF_SPMI, MSM_QPNP_INT * There were few places where an earlier commit dcc2aedc80746acee589e4b47d3e6adf5d3ec253 missed adding dependence on SPMI along with MSM_SPMI. Fix them. * Add depends on ARCH_MSM. ARCH_MSM is used for internal builds. Change the nodes in DTSI files to confirm to the modified drivers. Update their binding docs to drop spmi-dev-container and spmi-slave-container; Finally update defconfig to use upstream SPMI.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The commit 54e8827d5f0e ("mfd: sec-core: Add support for S2MPU02 device") added new MFD child devices for S2MPU02: RTC and clock provider (the clock provider with new compatible). However support for these devices was not added to existing drivers (rtc-s5m, clk-s2mps11). New drivers were not submitted neither. This means that the name of children devices is completely unused. The "samsung,s2mpu02-clk" compatible remains undocumented so it is unclear what is provided by that compatible. Clean up this by removing unused child devices and undocumented compatible.

However on some boards (with S2MPS13) the pin is pulled down so any suspend will effectively trigger the reset of bucks supplying the power to the little and big cores. In the same time when resuming, these bucks must provide voltage greater or equal to voltage before suspend to match the frequency chosen by cpufreq. If voltage (default value of voltage after reset) is lower than one set by cpufreq before suspend, then system will hang during resuming.

| * | mfd: Kconfig: Compile MFD_STW481X with COMPILE_TESTLuis de Bethencourt2015-10-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The driver depends on ARCH_NOMADIK but there isn't a build dependency so it's a good idea to allow the driver to always be built when the COMPILE_TEST option is enabled. That way, the driver can be built with a config generated by make allyesconfig and check if a patch would break the build.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Definitions for GPIO registers 8, 9, 10, 11, 12 and 13 are added into the register header file. - DA9052_GPIO_8_9_REG 25 - DA9052_GPIO_10_11_REG 26 - DA9052_GPIO_12_13_REG 27 A modification is also made to the MFD core code to define these registers as readable and writable. The functions for da9052_reg_readable() and da9052_reg_writeable() have had their case statements altered to include these new registers.

| * | mfd: atmel-flexcom: Add a driver for Atmel Flexible Serial Communication UnitCyrille Pitchen2015-10-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This driver supports the new Atmel Flexcom. The Flexcom is a wrapper which integrates one SPI controller, one I2C controller and one USART. Only one function can be enabled at a time. This driver selects the function once for all, when the Flexcom is probed, according to the value of the new "atmel,flexcom-mode" device tree property. This driver has chosen to present the Flexcom to the system as a MFD so the implementation is seamless for the existing Atmel SPI, I2C and USART drivers. Also the Flexcom embeds FIFOs: the latest patches of the SPI, I2C and USART drivers take advantage of this new feature.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The call to kstrtoul() will corrupt memory on 64 bit systems because an int is 4 bytes and a long is 8. Also it's not a good idea to let users trigger a dev_err() because it just ends up flooding /var/log/messages so I removed the printk.
