Subject: wifi: mt76: mt7925: add MT7927 chip ID helpers
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=752003c6d9b8531a5f9005d42821ccc24b553fbc;p=thirdparty%2Flinux.git

wifi: mt76: mt7925: add MT7927 chip ID helpers

The MediaTek MT7927 (Filogic 380) combo chip uses MT7927 WiFi silicon
that is architecturally compatible with MT7925. Extend is_mt7925() to
match chip ID 0x7927, and add is_mt7927() for code paths that need
MT7927-specific handling.

Also add 0x7927 to is_mt76_fw_txp() to match MT7925's TXP format.
