Subject: [PATCH v16 0/9] Add support for audio on SC7280 based targets

This patch set is to add support for Audio over wcd codec,
digital mics, through digital codecs and without ADSP.

Changes Since V15:
    -- Bisect patches to avoid build failure in other architectures.
    -- Remove redundant variables lpass variant structure.
Changes Since V14:
    -- Split common wrapper function to separate wrapper for each handle in platform driver.
    -- Update cdc dma buffer handling with memremap with ioremap.    
    -- Remove redundant error prints.
    -- Update irq flag.
Changes Since V13:
    -- Change bulk cdc clock voting to individual clock voting.
    -- Remove redundant code, conditional check and prints.
    -- Fix typo errors.
Changes Since V12:
    -- Fix arguments type mismatch.
Changes Since V11:
    -- Fix kernel robot issue on arguments type mismatch.
Changes Since V10:
    -- Split bulk clock voting to individual clock voting as per use case in cdc-dma driver.
    -- Add missing codec dma clocks.
    -- Update rxtx lpm buffer size.
Changes Since V9:
    -- Change individual clock voting to bulk clock voting of lpass-sc7280 platform driver.
    -- Remove redundant clocks in lpass variant structure.
    -- Add mclk for MI2S based headset path.
    -- Remove unused lpass variant structure members in lpass header.
Changes Since V8:
    -- Fix errors in sc7280 lpass cpu dt-bindings.
    -- Move to quicinc domain email id's.
Changes Since V7:
    -- Fix indentation errors.
    -- Bisect patches to avoid interdependency.
Changes Since V6:
    -- Split cdc dma regmap config macros.
    -- Add write dma reg fields for i2s path.
    -- Add helper function to distinguish rxtx and va dma ports.
    -- Optimizing clock and reg name in cpu dt-bindings.
    -- Update buffer management for cdc dma path.
    -- Remove Kconfig fields of machine driver.
Changes Since V5:
    -- Include MI2S primary node to snd_soc_dai_driver in lpass-sc7280 platform driver.
    -- Move dependency patch list to corresponding patch.
    -- Add support for missing cdc-dma ports.
    -- Change if/else conditional statements to switch cases.
    -- Add missing error handlings.
    -- Typo errors fix.
Changes Since V4:
    -- Remove unused variable in lpass-sc7280 platform driver.
Changes Since V3:
    -- Remove redundant power domain controls. As power domains can be configured from dtsi.
Changes Since V2:
    -- Split lpass sc7280 cpu driver patch and create regmap config patch.
    -- Create patches based on latest kernel tip.
    -- Add helper function to get dma control and lpaif handle.
    -- Remove unused variables.
Changes Since V1:
    -- Typo errors fix
    -- CPU driver readable/writable apis optimization.
    -- Add Missing config patch
    -- Add Common api for repeated dmactl initialization.
