Signed-off-by: Max Chou --- Changes in v2: - Separate the code description for ACPI and OF - Note that forgiving my less experience, I can not find bt3wire.c from the upstream. I just find hci_h5.c can support Realtek Bluetooth controller, so I modify the code here for new chip support. --- drivers/bluetooth/Kconfig | 2 +- drivers/bluetooth/btrtl.c | 12 ++++++++++++ drivers/bluetooth/hci_h5.c | 19 +++++++++++++++++++ 3 files changed, 32 insertions(+), 1 deletion(-) diff --git a/drivers/bluetooth/Kconfig b/drivers/bluetooth/Kconfig index f7aa2dc1ff85..052020b07e56 100644 --- a/drivers/bluetooth/Kconfig +++ b/drivers/bluetooth/Kconfig @@ -211,7 +211,7 @@ config BT_HCIUART_RTL depends on BT_HCIUART depends on BT_HCIUART_SERDEV depends on GPIOLIB - depends on ACPI + depends on (ACPI || SERIAL_DEV_CTRL_TTYPORT) select BT_HCIUART_3WIRE select BT_RTL help diff --git a/drivers/bluetooth/btrtl.c b/drivers/bluetooth/btrtl.c index 577cfa3329db..67f4bc21e7c5 100644 --- a/drivers/bluetooth/btrtl.c +++ b/drivers/bluetooth/btrtl.c @@ -136,6 +136,18 @@ static const struct id_table ic_id_table[] = { .fw_name = "rtl_bt/rtl8761a_fw.bin", .cfg_name = "rtl_bt/rtl8761a_config" }, + /* 8822C with UART interface */ + { .match_flags = IC_MATCH_FL_LMPSUBV | IC_MATCH_FL_HCIREV | + IC_MATCH_FL_HCIBUS, + .lmp_subver = RTL_ROM_LMP_8822B, + .hci_rev = 0x000c, + .hci_ver = 0x0a, + .hci_bus = HCI_UART, + .config_needed = true, + .has_rom_version = true, + .fw_name = "rtl_bt/rtl8822cs_fw.bin", + .cfg_name = "rtl_bt/rtl8822cs_config" }, + /* 8822C with USB interface */ { IC_INFO(RTL_ROM_LMP_8822B, 0xc), .config_needed = false, diff --git a/drivers/bluetooth/hci_h5.c b/drivers/bluetooth/hci_h5.c index 0b14547482a7..4e4d58a73295 100644 --- a/drivers/bluetooth/hci_h5.c +++ b/drivers/bluetooth/hci_h5.c @@ -11,6 +11,7 @@ #include #include #include +#include #include #include @@ -786,6 +787,7 @@ static const struct hci_uart_proto h5p = { static int h5_serdev_probe(struct serdev_device *serdev) { const struct acpi_device_id *match; + const void *data; struct device *dev = &serdev->dev; struct h5 *h5; @@ -810,8 +812,15 @@ static int h5_serdev_probe(struct serdev_device *serdev) if (h5->vnd->acpi_gpio_map) devm_acpi_dev_add_driver_gpios(dev, h5->vnd->acpi_gpio_map); + } else { + data = of_device_get_match_data(dev); + if (!data) + return -ENODEV; + + h5->vnd = (const struct h5_vnd *)data; } + h5->enable_gpio = devm_gpiod_get_optional(dev, "enable", GPIOD_OUT_LOW); if (IS_ERR(h5->enable_gpio)) return PTR_ERR(h5->enable_gpio); @@ -1003,6 +1012,15 @@ static const struct dev_pm_ops h5_serdev_pm_ops = { SET_SYSTEM_SLEEP_PM_OPS(h5_serdev_suspend, h5_serdev_resume) }; +static const struct of_device_id rtl_bluetooth_of_match[] = { +#ifdef CONFIG_BT_HCIUART_RTL + { .compatible = "realtek,rtl8822cs-bt", + .data = (const void *)&rtl_vnd }, +#endif + { }, +}; +MODULE_DEVICE_TABLE(of, rtl_bluetooth_of_match); + static struct serdev_device_driver h5_serdev_driver = { .probe = h5_serdev_probe, .remove = h5_serdev_remove, @@ -1010,6 +1028,7 @@ static struct serdev_device_driver h5_serdev_driver = { .name = "hci_uart_h5", .acpi_match_table = ACPI_PTR(h5_acpi_match), .pm = &h5_serdev_pm_ops, + .of_match_table = rtl_bluetooth_of_match, }, };
