Bluetooth: btintel: Add Bluetooth SAR revision 2 support
BRDS revision 2 introduces per-chain (Chain A and Chain B) TX power
limits across five sub-bands (2.4G, 5.2G, 5.8/5.9G, 6G-low, 6G-high),
replacing the single-chain per-modulation model of revisions 0 and 1.
- Add btintel_set_sar_rev2() which sends the full Rev2 DDC sequence:
0x019e inc-power-mode enable flag (1 byte)
0x0311 2.4 GHz sub-band limits (2 bytes)
0x0312 5.2 GHz sub-band limits (2 bytes)
0x0313 5.8/5.9 GHz sub-band limits (2 bytes)
0x0314 5.8/5.9 GHz sub-band limits again (2 bytes, duplicate FW reg)
0x0315 6 GHz low sub-band limits (2 bytes)
0x0316 6 GHz high sub-band limits (2 bytes)
followed by the SAR-init-complete command (0xfe25).
logs from dmesg when BTSAR2 is enabled in Coreboot/BIOS:
Bluetooth: hci0: BT SAR Rev2: revision=2 bt_sar_bios=1 inc_power_mode=1
Bluetooth: hci0: BT SAR Rev2 Chain A: 2g4=76 5g2=0 5g8_5g9=0 6g1=0 6g3=0
Bluetooth: hci0: BT SAR Rev2 Chain B: 2g4=102 5g2=0 5g8_5g9=0 6g1=0 6g3=0
