    Subject[PATCH v1 00/13] ASoC: qcom: add support to apq8016 audio
    Date
    Hi All,

    Thankyou for reviewing the RFC patches, here is the v1 patchset after
    incorporating review comments from RFC. This patchset adds apq8016 audio
    support into lpass driver. Existing Lpass driver can not be used as-it-is for
    apq8016 as it contains code specific to ipq806x. Also the driver only supports
    single i2s port, single dma channel and single bitclk control.

    APQ8016 has 4 MI2S( Primary, Secondary, Tertiary, Quaternary) which can be routed
    to internal wcd codec or external codecs. This routing is controlled by 2 mux
    registers.

    This patch series firstly re-organizes the lpass driver such that the SOC
    specific bits are moved away from the driver. And secondly the SOC specifics
    are now passed as lpass variant data which would include various register
    offsets, dma channel allocations and SOC specific clock handling.

    Finally the patchset add apq8016 lpass and machine driver.

    All these patches are tested for HDMI audio via adv7533 bridge and Analog audio
    on APQ8016-SBC and msm8916-mtp boards. I dont have access to ipq806x boards to
    test these patches.

    Thanks Kenneth for testing the RFC patches on Storm board.

    Changes since RFC(https://lwn.net/Articles/642661/)
    - droped cleanup patches, as they are already applied by Mark.
    - prefixed shared functions with asoc_qcom_* as suggested by Kenneth
    - made LPASS driver depended on OF.
    - removed ipq806x specific bits from ipaif_reg.h
    - removed no_osr clk flag as suggested by Mark and Kenneth
    - fixed irq return values spotted by Kenneth
    - renamed the machine file to apq8016-sbc.c as suggested by Kenneth.
    - use dai->driver->id instead of dai->id as it breaks on Storm board.
