Merge series "Qualcomm's lpass-hdmi ASoC driver to support audio over dp port" from Srinivasa Rao Mandadapu <[email protected]>:

These patches are to support audio over DP port on Qualcomm's SC7180 LPASS
Asoc. It includes machine driver, cpu driver, platform driver updates for
HDMI path support, device tree documention, lpass variant structure
optimization and configuration changes.
These patches depends on the DP patch series
https://patchwork.kernel.org/project/dri-devel/list/?series=332029
https://lore.kernel.org/patchwork/project/lkml/list/?series=464856

changes since V10:
    -- Moved hdmi regmap functions from lpass-hdmi.c to lpass-cpu.c
    -- Moved QCOM_REGMAP_FIELD_ALLOC macro from lpass-hdmi.c to lpass.h
changes since V9:
    -- Removed unused structures lpass_hdmi.h
changes since V8:
    -- Removed redundant structure wrapper for reg map field memebrs
    -- Updated lpass_hdmi_regmap_volatile API with appropriate registers as true
       and others as false.
changes since V7:
    -- Fixed typo errors
    -- Created Separate patch for buffer size change
changes since V6:
    -- Removed compile time define flag, which used for enabling
     HDMI code, based on corresponding config param is included.
    -- Updated reg map alloc API with reg map bulk API.
    -- Removed unnecessary line splits
changes since V5:
    -- Removed unused struct regmap *map in lpass_platform_alloc_hdmidmactl_fields.
    -- DMA alloc and free API signature change in lpass-apq8016.c, lpass-ipq806x.c
    -- Keeping API "irqreturn_t lpass_platform_hdmiif_irq" under ifdef macro
Changes Since v4:
    -- Updated with single compatible node for both I2S and HDMI.
Changes Since v3:
    -- Removed id in lpass variant structure and used snd_soc_dai_driver id.
Changes Since v2:
    -- Audio buffer size(i.e. LPASS_PLATFORM_BUFFER_SIZE) in lpass-platform.c increased.
Changes Since v1:
    -- Commit messages are updated
    -- Addressed Rob Herring review comments
