2020-06-23Bluetooth: btmtksdio: fix up firmware download sequenceGravatar Sean Wang 1-1/+15
Data RAM on the device have to be powered on before starting to download the firmware.

2019-11-07Bluetooth: btmtksdio: add MODULE_DEVICE_TABLE()Gravatar Bartosz Golaszewski 1-0/+1
This adds the missing MODULE_DEVICE_TABLE() for SDIO IDs. While certain platforms using this driver indeed have HW issues causing problems if the module is loaded too early - this should be handled from user-space by blacklisting it or delaying the loading.

2019-04-23Bluetooth: btmtksdio: Add runtime PM support to SDIO based BluetoothGravatar Sean Wang 1-0/+144
Add runtime PM support to btmtksdio. With this way, there will be the benefit of the device entering the more power saving state once it is been a while data traffic is idle. Signed-off-by: Sean Wang <sean.wang@mediatek.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2019-04-23Bluetooth: btmtksdio: Fix hdev->stat.byte_rx accumulationGravatar Sean Wang 1-2/+2
Accumulate hdev->stat.byte_rx only for valid packets as btmtkuart doing. Signed-off-by: Sean Wang <sean.wang@mediatek.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2019-04-23Bluetooth: btmtksdio: Add a bit definition for CHLPCRGravatar Sean Wang 1-3/+4
Add a register bit definition about CHLPCR bit 8 because the bit is quite different in the meaning between reading and writing that bit. The patch adds a definition particularly for the bit read to avoid the confusion about using write definition to read the bit.

2019-04-23Bluetooth: btmtksdio: Drop newline with bt_dev logging macrosGravatar Sean Wang 1-3/+3
bt_dev logging macros already include a newline at each output so drop these unnecessary additional newlines in the driver. Signed-off-by: Sean Wang <sean.wang@mediatek.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2019-04-23Bluetooth: btmtksdio: fix uninitialized symbol errors in btmtksdio_rx_packetGravatar Sean Wang 1-10/+0
Fixed all the below warnings. They would probably cause the following error handling path would use the uninitialized value and then produce unexpected behavior. drivers/bluetooth/btmtksdio.c:470:2: warning: ‘old_len’ may be used uninitialized in this function [-Wmaybe-uninitialized] print_hex_dump(KERN_ERR, "err sdio rx: ", DUMP_PREFIX_NONE, 4, 1, ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ old_data, old_len, true); ~~~~~~~~~~~~~~~~~~~~~~~~ drivers/bluetooth/btmtksdio.c:376:15: note: ‘old_len’ was declared here unsigned int old_len; ^~~~~~~ drivers/bluetooth/btmtksdio.c:470:2: warning: ‘old_data’ may be used uninitialized in this function [-Wmaybe-uninitialized] print_hex_dump(KERN_ERR, "err sdio rx: ", DUMP_PREFIX_NONE, 4, 1, ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ old_data, old_len, true); ~~~~~~~~~~~~~~~~~~~~~~~~ drivers/bluetooth/btmtksdio.c:375:17: note: ‘old_data’ was declared here unsigned char *old_data; ^~~~~~~~ v2: Remove old_len and old_data because the error path for sdio_readsb also seems wrong.

2019-04-23Bluetooth: mediatek: Use module_sdio_driver helperGravatar Sean Wang 1-14/+1
Macro module_sdio_driver is used for drivers whose init and exit paths only register and unregister to SDIO API. So remove boilerplate code to make code simpler by using module_sdio_driver.

2019-04-23Bluetooth: mediatek: add support for MediaTek MT7663S and MT7668S SDIO devicesGravatar Sean Wang 1-0/+979
This adds the support of enabling MT7663S and MT7668S SDIO-based Bluetooth function. There are quite many differences between MT766[3,8]S and standard Bluetooth SDIO devices such as Type-A and Type-B devices. For example, MT766[3,8]S have its own SDIO registers layout, definition, SDIO packet format, and the specific flow should be programmed on them to complete the device initialization and low power control and so on. Currently, there are many independent programming sequences from the transport which are exactly the same as the ones in btusb.c about MediaTek support [1] and btmtkuart.c. We can try to split the transport independent Bluetooth setups on the advance, place them into the common files and allow varous transport drivers to reuse them in the future.
