Pull MFD updates from Lee Jones:
 "New Drivers:
   - Intel Cherry Trail Whiskey Cove PMIC
   - TI LP87565 PMIC

  New Device Support:
   - Add support for Cannonlake to intel-lpss-pci
   - Add support for Simatic IOT2000 to intel_quark_i2c_gpio

  New Functionality:
   - Add Regulator support (axp20x)

  Fix-ups:
   - Rework IRQ handling (intel_soc_pmic_bxtwc, rtsx_pcr, cros_ec)
   - Remove unused/unwelcome code (ipaq-micro, wm831x-core, da9062-core)
   - Provide deregistration on unbind (rn5t618)
   - Rework DT code/documentation (arizona)
   - Constify things (fsl-imx25-tsadc)
   - MAINTAINERS updates (DA9062/61)
   - Kconfig configuration adaptions (INTEL_SOC_PMIC, MFD_AXP20X_I2C)
   - Switch to DMI matching (intel_quark_i2c_gpio)
   - Provide an appropriate level of error checking (wm831x-{i2c,spi},
     twl4030-irq, tc6393xb)
   - Make use of devm_* (resource handling) calls (intel_soc_pmic_bxtwc,
     stm32-timers, atmel-flexcom, cros_ec, fsl-imx25-tsadc,
     exynos-lpass, palmas, qcom-spmi-pmic, smsc-ece1099,
     motorola-cpcap)"
