Hi All,
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.
This patchset also has two trivial cleanup patches which are to do with redundant checks and removing unnecessary header files.
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.
This is very first version of the patches which was developed with very mimimal/no access to IP documentation. I would like to get your opinon on the over all approch.
Kenneth/Patrick, Could you please try these patches on storm board?
I will test the patches and let you know by Wednesday. Also, I posted some comments, but Patrick should be posting his comments separately later next week.
