Subject: [PATCH v4 0/4] Qualcomm SPMI PMIC pin controller drivers

Hi, 

This is forth version of the patches posted earlier here[1].

Changes:
- Driver for SSBI PMIC dropped from this patchest - let Bjorn to handle it.
- Separate MPP and GPIO drivers.
- Second value in 'reg' propriety is used to specify address range length
  and this number of GPIO/MPP's that drivers should handle.
- Using generic compatible = "qcom,spmi-pmic-gpio" in GPIO driver to handle
  any PMIC SPMI based GPIO block.
- Using generic compatible = "qcom,spmi-pmic-mpp" in MPP driver to handle
  any PMIC SPMI based MPP block.
- Analog functionality for MPP's is activated with qcom,analog-mode.
- Fixed review comments and driver issues.

Short description:

Patches adds pin control drivers for Multi-Purpose Pin (MPP) and
General-purpose pin (GPIO) controllers found in Qualcomm SPMI based
PMIC chips.

MPP's are enhanced GPIO's with analog circuits, which support 
analog and digital input/output.
