Subject: [PATCH v3 0/2] slimbus: Add QCOM SLIMBus NGD driver

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@...eaurora.org> and
Sagar Dharia <sdharia@...eaurora.org>

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.

This patch has dependency on https://lkml.org/lkml/2018/5/17/251

Changes sinc v1 (https://lkml.org/lkml/2018/5/25/296):
- Added Tested-by and Reviewed-by Tags
- Added Credits to Qualcomm engineers in commit log
- Fixed a spelling mistake for prepare.

Thanks,
srini
