Hello,
The following series will add support for OMAP4 DMIC interface, and enable them on sdp4430/Blaze boards.
Changes since v3: - dmic clk divider selection moved to hw_params phase to allow fixed rate configuration from machine driver init.
Changes since v2: - Use module_platform_driver - convert to use devm_ - Add clk_id for the output clock - Extend the comment to explain why the driven can change the divider for 192KHz sampling rate.
Changes since v1: - 192KHz rate support fixed (need to use different divider) - Hold reference for dmic_fclk over the lifetime of the driver - Removed the clkdiv callback, and replaced with frequency based configuration for the external components (dmic frequency)
