Subject: ath9k: Add a delay between RTC reset/clear for AR9003
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=afe36533c108f55c5245397a1cc82af312a32614;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

ath9k: Add a delay between RTC reset/clear for AR9003

The small delay that is present between a RTC reset/clear
operation is required for the chip to settle and this is
needed for all chips, not just the AR9002 family.
