Loic Poulain d06f107bcd Bluetooth: btintel: Add iBT register access over HCI support ... 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 <loic.poulain@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>		2015-10-03 19:03:15 +02:00
