Subject: [PATCH v2 0/4] New Qualcomm PMIC pin controller drivers

From: "Ivan T. Ivanov" <iivanov@...sol.com>

Hi, 

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

Patches could be applied on top of the Bjorn Andersson
qcom,pm8xxx-gpio driver, which could be found here[2].

Fist patch modify Bjorn's driver and bindings to make room
for newer Qualcomm PMIC chips. It is not completely ready.

Changes:
- Remove registers values cache.
- Merge pm8941 and pm8841 into qpnp-pinctrl driver.
- Rebase on top of the "Qualcomm pm8xxx gpio driver" to reuse
  "qcom,pm8xxx-gpio" DT document.
- Split compatibles string to MPP's and GPIO's to use
  similar naming convention like "Qualcomm pm8xxx gpio driver"[2]
- Add support for pma8084 chip

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 
following functions in addition to digital input/output: analog
input/output and current sinks.
