From 528379902337102b0264fe5343eafb3d6c59fa45 Mon Sep 17 00:00:00 2001 From: Abhishek Pandit-Subedi Date: Tue, 26 Nov 2019 08:17:30 +0100 Subject: Bluetooth: btbcm: Support pcm configuration Add BCM vendor specific command to configure PCM parameters. The new vendor opcode allows us to set the sco routing, the pcm interface rate, and a few other pcm specific options (frame sync, sync mode, and clock mode). See broadcom-bluetooth.txt in Documentation for more information about valid values for those settings. Here is an example trace where this opcode was used to configure a BCM4354: < HCI Command: Vendor (0x3f|0x001c) plen 5 01 02 00 01 01 > HCI Event: Command Complete (0x0e) plen 4 Vendor (0x3f|0x001c) ncmd 1 Status: Success (0x00) We can read back the values as well with ocf 0x001d to confirm the values that were set: $ hcitool cmd 0x3f 0x001d < HCI Command: ogf 0x3f, ocf 0x001d, plen 0 > HCI Event: 0x0e plen 9 01 1D FC 00 01 02 00 01 01 Signed-off-by: Abhishek Pandit-Subedi Signed-off-by: Marcel Holtmann Signed-off-by: Johan Hedberg --- drivers/bluetooth/btbcm.h | 16 ++++++++++++++++ 1 file changed, 16 insertions(+) (limited to 'drivers/bluetooth/btbcm.h') diff --git a/drivers/bluetooth/btbcm.h b/drivers/bluetooth/btbcm.h index d204be8a84bf..3c7dd0765837 100644 --- a/drivers/bluetooth/btbcm.h +++ b/drivers/bluetooth/btbcm.h @@ -54,6 +54,10 @@ struct bcm_set_pcm_format_params { int btbcm_check_bdaddr(struct hci_dev *hdev); int btbcm_set_bdaddr(struct hci_dev *hdev, const bdaddr_t *bdaddr); int btbcm_patchram(struct hci_dev *hdev, const struct firmware *fw); +int btbcm_read_pcm_int_params(struct hci_dev *hdev, + struct bcm_set_pcm_int_params *params); +int btbcm_write_pcm_int_params(struct hci_dev *hdev, + const struct bcm_set_pcm_int_params *params); int btbcm_setup_patchram(struct hci_dev *hdev); int btbcm_setup_apple(struct hci_dev *hdev); @@ -74,6 +78,18 @@ static inline int btbcm_set_bdaddr(struct hci_dev *hdev, const bdaddr_t *bdaddr) return -EOPNOTSUPP; } +int btbcm_read_pcm_int_params(struct hci_dev *hdev, + struct bcm_set_pcm_int_params *params) +{ + return -EOPNOTSUPP; +} + +int btbcm_write_pcm_int_params(struct hci_dev *hdev, + const struct bcm_set_pcm_int_params *params) +{ + return -EOPNOTSUPP; +} + static inline int btbcm_patchram(struct hci_dev *hdev, const struct firmware *fw) { return -EOPNOTSUPP; -- cgit v1.2.3
