Commit Message

Harish Bandi March 26, 2019, 11:45 a.m. UTC
Added new compatible for WCN3998 and corresponding voltage
and current values to WCN3998 compatible.
Changed driver code to support WCN3998

Signed-off-by: Harish Bandi <c-hbandi@codeaurora.org>
---
Changes in V5:
- changed is_qca_soc_type_wcn399x_family to
- qca_is_wcn399x helper function 
- moved the qca_is_wcn399x function to btqca.c
