* Bluetooth: btqca: Introduce HCI_EV_VENDOR and use itMarcel Holtmann2018-08-061-3/+3
| | | | | | | | | | Using HCI_VENDOR_PKT for vendor specific events does work since it has also the value 0xff, but it is actually the packet type indicator constant and not the event constant. So introduce HCI_EV_VENDOR and use it. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>

Added new arguments soc_type and soc_ver to the functions.

| | | | | | | | | | | | | | | Some of the QCA BTSoC ROME functions, are used for different versions or different make of BTSoC's. Instead of duplicating the same functions for new chip, update names of the functions that are used for both chips to keep this generic and would help in future when we would have new BT SoC. To have generic text in logs updated from ROME to QCA where ever possible. This avoids confusion to user, when using the future Qualcomm Bluetooth SoC's.

* Bluetooth: btrtl: add support for the RTL8723BS and RTL8723DS chipsMartin Blumenstingl2018-08-031-4/+47
| | | | | | | | | | | | | | | | | The Realtek RTL8723BS and RTL8723DS chipsets are SDIO wifi chips. They also contain a Bluetooth module which is connected via UART to the host. Realtek's userspace initialization tool (rtk_hciattach) differentiates these two via the HCI version and revision returned by the HCI_OP_READ_LOCAL_VERSION command. Additionally we apply these checks only the for UART devices. Everything else is assumed to be a "RTL8723B" which was originally supported by the driver (communicating via USB).

* Bluetooth: btrtl: add support for retrieving the UART settingsMartin Blumenstingl2018-08-032-0/+134
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The UART settings are embedded in the config blob. This has to be parsed to successfully initialize the Bluetooth part of the RTL8723BS (which is an SDIO chip, but the Bluetooth part is connected via UART). The Realtek "rtl8723bs_bt" and "rtl8723ds_bt" userspace Bluetooth UART initialization tools (rtk_hciattach) use the following sequence: - send H5 sync pattern (already supported by hci_h5) - get LMP version (already supported by btrtl) - get ROM version (already supported by btrtl) - load the firmware and config for the current chipset (already supported by btrtl) - read UART settings from the config blob (part of this patch) - send UART settings via a vendor command to the device (which changes the baudrate of the device and enables or disables flow control depending on the config) - change the baudrate and flow control settings on the host - send the firmware and config blob to the device (already supported by btrtl) Sending the last firmware and config blob download command (rtl_download_cmd) fails if the UART settings are not updated beforehand. This is presumably because the device applies the config right after the firmware and config blob download - which means that at this point the host is using different UART settings than the device (which will obviously result in non-working communication).

* Bluetooth: btrtl: split the device initialization into smaller partsMartin Blumenstingl2018-08-032-106/+199
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This prepares the btrtl code so it can be used to initialize Bluetooth modules connected via UART (these are found for example on the RTL8723BS and RTL8723DS SDIO chips, which come with an embedded UART Bluetooth module). The Realtek "rtl8723bs_bt" and "rtl8723ds_bt" userspace Bluetooth UART initialization tools (rtk_hciattach) use the following sequence: 1) send H5 sync pattern (already supported by hci_h5) 2) get LMP version (already supported by btrtl) 3) get ROM version (already supported by btrtl) 4) load the firmware and config for the current chipset (already supported by btrtl) 5) read UART settings from the config blob (currently not supported) 6) send UART settings via a vendor command to the device (which changes the baudrate of the device and enables or disables flow control depending on the config) 7) change the baudrate and flow control settings on the host 8) send the firmware and config blob to the device (already supported by btrtl) The main reason why the initialization has to be split is step #7. This requires changes to the underlying "bus", which should be kept outside of the "generic" btrtl driver. The idea for this split is borrowed from the btbcm driver but adjusted where needed (the btrtl driver for example needs two blobs: firmware and config, while the btbcm only needs one). This also prepares the code for step #5 (parsing the config blob) by centralizing the code which loads the firmware and config blobs and storing the result in the new struct btrtl_device_info.

| | | | | | | | | | | | | | | | The USB completion callback does not disable interrupts while acquiring the ->lock. We want to remove the local_irq_disable() invocation from __usb_hcd_giveback_urb() and therefore it is required for the callback handler to disable the interrupts while acquiring the lock. The callback may be invoked either in IRQ or BH context depending on the USB host controller. Use the _irqsave variant of the locking primitives.

* Bluetooth: btusb: Apply QCA Rome patches for some ATH3012 modelsTakashi Iwai2018-05-291-7/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In commit f44cb4b19ed4 ("Bluetooth: btusb: Fix quirk for Atheros 1525/QCA6174") we tried to address the non-working Atheros BT devices by changing the quirk from BTUSB_ATH3012 to BTUSB_QCA_ROME. This made such devices working while it turned out to break other existing chips with the very same USB ID, hence it was reverted afterwards. This is another attempt to tackle the issue. The essential point to use BTUSB_QCA_ROME is to apply the btusb_setup_qca() and do RAM- patching. And the previous attempt failed because btusb_setup_qca() returns -ENODEV if the ROM version doesn't match with the expected ones. For some devices that have already the "correct" ROM versions, we may just skip the setup procedure and continue the rest. So, the first fix we'll need is to add a check of the ROM version in the function to skip the setup if the ROM version looks already sane, so that it can be applied for all ath devices. However, the world is a bit more complex than that simple solution. Since BTUSB_ATH3012 quirk checks the bcdDevice and bails out when it's 0x0001 at the beginning of probing, so the device probe always aborts here. In this patch, we add another check of ROM version again, and if the device needs patching, the probe continues. For that, a slight refactoring of btusb_qca_send_vendor_req() was required so that the probe function can pass usb_device pointer directly before allocating hci_dev stuff.
