Subject: [PATCH v13 0/7] Add pin control support for lpass sc7280

This patch series is to split lpass variant common pin control
functions and SoC specific functions and to add lpass sc7280 pincontrol support.
It also Adds dt-bindings for lpass sc7280 lpass lpi pincontrol.

Changes Since V12:
    -- Remove redundant comments in sc7280 and sm8250 lpass lpi drivers.
    -- Rebased on top of latest kernel tip.
Changes Since V11:
    -- Add pinctrl_generic_remove_group in lpass lpi driver.
    -- Make proper error handling in lpass lpi driver.
Changes Since V10:
    -- Modify driver's custom functions with pin control framework generic functions.
    -- Update sm8250 and sc7280 pin control depedency list in Kconfig.
    -- Update commit description of few patches.
Changes Since V9:
    -- Add pinctrl groups macro to Kconfig.
Changes Since V8:
    -- Remove redundant headers included in v8.
Changes Since V7:
    -- Update optional clock voting with conditional check.
    -- Add const to lpi_pinctrl_variant_data structure.
    -- Update required headers and remove redundant.
    -- Change EXPORT_SYMBOL to EXPORT_SYMBOL_GPL
    -- Fix typo errors.
Changes Since V6:
    -- Update conditional clock voting to optional clock voting.
    -- Update Kconfig depends on field with select.
    -- Fix typo errors. 
Changes Since V5:
    -- Create new patch by updating macro name to lpi specific.
    -- Create new patch by updating lpi pin group structure with core group_desc structure.
    -- Fix typo errors.
    -- Sort macros in the make file and configuration file.
Changes Since V4:
    -- Update commit message and description of the chip specific extraction patch.
    -- Sort macros in kconfig and makefile.
    -- Update optional clock voting to conditional clock voting.
    -- Fix typo errors.
    -- Move to quicinc domain email id's.
Changes Since V3:
    -- Update separate Kconfig fields for sm8250 and sc7280.
    -- Update module license and description.
    -- Move static variables to corresponding .c files from header file.

Changes Since V2:
    -- Add new dt-bindings for sc7280 lpi driver.
    -- Make clock voting change as separate patch.
    -- Split existing pincontrol driver and make common functions 
       as part of separate file.
    -- Rename lpass pincontrol lpi dt-bindings to sm8250 specific dt-bindings
		
Changes Since V1:
    -- Make lpi pinctrl variant data structure as constant
    -- Add appropriate commit message
    -- Change signedoff by sequence.

Srinivasa Rao Mandadapu (7):
  dt-bindings: pinctrl: qcom: Update lpass lpi file name to SoC specific
  dt-bindings: pinctrl: qcom: Add sc7280 lpass lpi pinctrl bindings
  pinctrl: qcom: Update macro name to LPI specific
  pinctrl: qcom: Update lpi pin group custiom functions with framework
    generic functions
  pinctrl: qcom: Extract chip specific LPASS LPI code
  pinctrl: qcom: Add SC7280 lpass pin configuration
  pinctrl: qcom: Update clock voting as optional

Tested this on SM8250 MTP with WSA and WCD codecs.
