This patchset adds support to basic version of Qualcomm NGD SLIMBus controller driver found SoCs from B family.
This controller is light-weight SLIMBus controller driver responsible for communicating with slave HW directly over the bus using messaging interface, and communicating with master component residing on ADSP for bandwidth and data-channel management.
Tested this patchset on DB820c with WCD9335 codec. I have pushed my working branch to [1] incase someone want to try.
This patch has dependency on https://lkml.org/lkml/2018/5/17/251
Changes sinc v1 (https://lwn.net/Articles/754679):
- Fixed DT binding making NGD slave of the slim controller.
- Fixed few typos spotted by Vinod.
- Removed unnessary dmaengine_slave_config suggested by Vinod
- Removed few unnessary initializations.
- fixed commit log to remove reference to B family suggested by Trilok
Thanks, srini
