    Subject[PATCH v2 0/4] New Qualcomm PMIC pin controller drivers
    Date
    From: "Ivan T. Ivanov" <iivanov@mm-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.
