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. Some parts fot the work is derived from Qualcomm downstream kernels and intial work from Karthikeyan Ramasubramanian <kramasub@xxxxxxxxxxxxxx> and Sagar Dharia <sdharia@xxxxxxxxxxxxxx> Tested this patchset on DB820c with WCD9335 codec and on msm8974 with wcd9320 codec. I have pushed my working branch to [1] incase someone want to try.
