Subject: wifi: rtw89: rfk: update RFK pre info V2 for RTL8922D
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8c0ac5791eb9a82426ac1f5b6ea7aa1e3f921815;p=thirdparty%2Fkernel%2Flinux.git

wifi: rtw89: rfk: update RFK pre info V2 for RTL8922D

The H2C command of RFK pre info is to tell current operating channels to
firmware, so RF calibrations can rely on these information as arguments
to configure hardware.
