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.
