From: George Moussalem <[email protected]> Add the IPQ5018 SoC type and support for loading its firmware. The firmware tested has been taken from GPL sources of various router boards. Firmware files needed are: - qca/bt_fw_patch.mbn - qca/mpnv10.bin Signed-off-by: George Moussalem <[email protected]> --- drivers/bluetooth/btqca.c | 16 ++++++++++++++++ drivers/bluetooth/btqca.h | 3 +++ 2 files changed, 19 insertions(+) diff --git a/drivers/bluetooth/btqca.c b/drivers/bluetooth/btqca.c index 04ebe290bc78..e136e91976cf 100644 --- a/drivers/bluetooth/btqca.c +++ b/drivers/bluetooth/btqca.c @@ -380,6 +380,9 @@ static int qca_tlv_check_data(struct hci_dev *hdev, break; case TLV_TYPE_NVM: + if (soc_type == QCA_IPQ5018) + break; + if (fw_size < sizeof(struct tlv_type_hdr)) return -EINVAL; @@ -794,6 +797,9 @@ int qca_uart_setup(struct hci_dev *hdev, uint8_t baudrate, else rom_ver = ((soc_ver & 0x00000f00) >> 0x04) | (soc_ver & 0x0000000f); + if (soc_type == QCA_IPQ5018) + goto download_nvm; + if (soc_type == QCA_WCN6750) qca_send_patch_config_cmd(hdev); @@ -881,6 +887,7 @@ int qca_uart_setup(struct hci_dev *hdev, uint8_t baudrate, if (soc_type == QCA_QCA2066 || soc_type == QCA_WCN7850) qca_read_fw_board_id(hdev, &boardid); +download_nvm: /* Download NVM configuration */ config.type = TLV_TYPE_NVM; if (firmware_name) { @@ -939,6 +946,10 @@ int qca_uart_setup(struct hci_dev *hdev, uint8_t baudrate, qca_get_nvm_name_by_board(config.fwname, sizeof(config.fwname), "hmtnv", soc_type, ver, rom_ver, boardid); break; + case QCA_IPQ5018: + snprintf(config.fwname, sizeof(config.fwname), + "qca/mpnv%02x.bin", rom_ver); + break; default: snprintf(config.fwname, sizeof(config.fwname), "qca/nvm_%08x.bin", soc_ver); @@ -958,6 +969,9 @@ int qca_uart_setup(struct hci_dev *hdev, uint8_t baudrate, return err; } + if (soc_type == QCA_IPQ5018) + msleep(NVM_READY_DELAY_MS); + switch (soc_type) { case QCA_QCA2066: case QCA_QCA6390: @@ -965,6 +979,7 @@ int qca_uart_setup(struct hci_dev *hdev, uint8_t baudrate, case QCA_WCN6750: case QCA_WCN6855: case QCA_WCN7850: + case QCA_IPQ5018: err = qca_disable_soc_logging(hdev); if (err < 0) return err; @@ -1001,6 +1016,7 @@ int qca_uart_setup(struct hci_dev *hdev, uint8_t baudrate, case QCA_WCN6750: case QCA_WCN6855: case QCA_WCN7850: + case QCA_IPQ5018: /* get fw build info */ err = qca_read_fw_build_info(hdev); if (err < 0) diff --git a/drivers/bluetooth/btqca.h b/drivers/bluetooth/btqca.h index 8f3c1b1c77b3..343cd62d1137 100644 --- a/drivers/bluetooth/btqca.h +++ b/drivers/bluetooth/btqca.h @@ -54,6 +54,8 @@ #define QCA_HSP_GF_SOC_ID 0x1200 #define QCA_HSP_GF_SOC_MASK 0x0000ff00 +#define NVM_READY_DELAY_MS 1500 + enum qca_baudrate { QCA_BAUDRATE_115200 = 0, QCA_BAUDRATE_57600, @@ -158,6 +160,7 @@ enum qca_btsoc_type { QCA_WCN6750, QCA_WCN6855, QCA_WCN7850, + QCA_IPQ5018, }; #if IS_ENABLED(CONFIG_BT_QCA) -- 2.53.0
