Bluetooth: btintel: Create common function for firmware download

2018-01-25T08:28:40+00:00

The firmware download flow for RAM SKU is same for both USB and UART and this patch creates a common function for both driver. Signed-off-by: Tedd Ho-Jeong An Signed-off-by: Marcel Holtmann

Bluetooth: btintel: Create common Intel Read Boot Params function

2018-01-24T18:31:49+00:00

The Intel_Read_Boot_Params command is used to read boot parameters from the bootloader and this is Intel generic command used in USB and UART drivers. Signed-off-by: Tedd Ho-Jeong An Signed-off-by: Marcel Holtmann

Bluetooth: btintel: Create common function for Intel Reset

2018-01-24T18:31:49+00:00

The Intel_Reset command is used to reset the device after downloading the firmware and this is Intel generic command used in both USB and UART. Signed-off-by: Tedd Ho-Jeong An Signed-off-by: Marcel Holtmann

Bluetooth: btintel: Create common Intel Version Read function

2015-12-09T23:51:51+00:00

The Intel Version Read command is used to retrieve information about hardware and firmware version/revision of Intel Bluetooth controllers. This is an Intel generic command used in USB and UART drivers. Signed-off-by: Loic Poulain Signed-off-by: Marcel Holtmann

Bluetooth: btintel: Add manufacturing enter/exit helpers

2015-12-09T23:51:50+00:00

Older Intel controllers need to enter manufacturing mode to perform some vendor specific operations (patching, configuration...). Add enter/exit manufaturing methods and refactor existing manufacturing code. Exit can be configured to perform a reset. Reset can be performed either with patches activated or deactivated.

Bluetooth: btintel: Enable extra Intel vendor events

2015-10-21T04:34:11+00:00

The Intel Bluetooth controllers can emit extra vendor specific events in error conditions or for debugging purposes. To make the life easier for engineers, enable them by default. When the vendor_diag options has been enabled, then additional debug events are also enabled. Signed-off-by: Marcel Holtmann Signed-off-by: Johan Hedberg

Bluetooth: btintel: Add diagnostic support for older controllers

2015-10-20T22:49:22+00:00

For the older controllers like Wilkens Peak and Stone Peak, enabling the traces requires to switch into manufacturer mode first. This patch does exactly that, but only for these older controllers. Signed-off-by: Marcel Holtmann Signed-off-by: Johan Hedberg

Bluetooth: btintel: Add support for enabling tracing functionality

2015-10-20T22:49:21+00:00

For Intel controllers with firmware that allows tracing of baseband functionality this allows enabling it via set_diag driver callback. Signed-off-by: Marcel Holtmann Signed-off-by: Johan Hedberg

Bluetooth: btintel: Add iBT register access over HCI support

2015-10-03T17:03:15+00:00

Add regmap ibt to support Intel Bluetooth silicon register access over HCI. Intel BT/FM combo chip allows to read/write some registers (e.g. FM registers) via its HCI interface. Read/Write operations are performed via a HCI transaction composed of a HCI command (host->controller) followed by a HCI command complete event (controller->host). Read/Write Command opcodes can be specified to the regmap init function. We define data formats which are intel/vendor specific. Register Read/Write HCI command payload (Host): Field: | REG ADDR | MODE | DATA_LEN | DATA... | size: | 32b | 8b | 8b | 8b* | Register Read HCI command complete event payload (Controller): Field: | CMD STATUS | REG ADDR | DATA... | size: | 8b | 32b | 8b* | Register Write HCI command complete event payload (Controller): Field: | CMD_STATUS | size: | 8b | Since this payload is HCI encapsulated, Little Endian byte order is used. Write/Read Example: If we write 0x0000002a at address 0x00008c04, with opcode_write 0xfc5d, The resulting transaction is (btmon trace): < HCI Command (0x3f|0x005d) plen 10 [hci0] 04 8c 00 00 02 04 2a 00 00 00 > HCI Event (0x0e) plen 4 Unknown (0x3f|0x005d) ncmd 1 00 Then, if we read the same register with opcode_read 0xfc5e: < HCI Command (0x3f|0x005e) plen 6 [hci0] 04 8c 00 00 02 04 > HCI Event (0x0e) plen 12 [hci0] Unknown (0x3f|0x005e) ncmd 1 00 04 8c 00 00 2a 00 00 00 Signed-off-by: Loic Poulain Signed-off-by: Marcel Holtmann
