Subject: ath10k: Add a table to store hw specific values
X-Git-Tag: firefly_0821_release~176^2~1159^2~246^2~43^2~37
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=2f2cfc4a9a5b7be65d61382b58cfb206f13966df;p=firefly-linux-kernel-4.4.55.git

ath10k: Add a table to store hw specific values

This is to prepare ath10k to support newer chip set.
Values like CE_COUNT, MSI_ASSIGN_CE_MAX and
RTC_STATE_V_ON can be different for different
chips.
