Subject: ath9k: Remove RTT/MCI code from SoC calibration
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a3640781d91334ba2a507b56cae18355fad8b479;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

ath9k: Remove RTT/MCI code from SoC calibration

RTT is enabled only for AR9462 and MCI for AR9462/AR9565.
Also, manual peak calibration is not done for any of the
SoC chips.
