Bluetooth: hci_qca: Avoid missing rampatch failure with userspace fw loader

2018-07-03T09:23:07+00:00

commit 7dc5fe0814c35ec4e7d2e8fa30abab72e0e6a172 upstream.

AOSP use userspace firmware loader to load firmwares, which will
return -EAGAIN in case qca/rampatch_00440302.bin is not found.
Since there is no rampatch for dragonboard820c QCA controller
revision, just make it work as is.

Bluetooth: hci_qca: Avoid setup failure on missing rampatch

2018-03-24T10:00:22+00:00

[ Upstream commit ba8f3597900291a93604643017fff66a14546015 ]

Assuming that the original code idea was to enable in-band sleeping
only if the setup_rome method returns succes and run in 'standard'
mode otherwise, we should not return setup_rome return value which
makes qca_setup fail if no rampatch/nvm file found.

This fixes BT issue on the dragonboard-820C p4 which includes the
following QCA controller:
hci0: Product:0x00000008
hci0: Patch  :0x00000111
hci0: ROM    :0x00000302
hci0: SOC    :0x00000044

Since there is no rampatch for this controller revision, just make
it work as is.

Bluetooth: Remove deprecated create_singlethread_workqueue

2016-09-19T18:19:34+00:00

The workqueue "workqueue" queues multiple work items viz &qca->ws_awake_rx
&qca->ws_rx_vote_off, &qca->ws_awake_device, &qca->ws_tx_vote_off which
require strict execution ordering. Hence, an ordered dedicated workqueue
has been used to replace the deprecated create_singlethread_workqueue
instance.

WQ_MEM_RECLAIM has not been set since the driver is not being used on a
memory reclaim path.

Bluetooth: Use new hci_skb_pkt_* wrappers for drivers

2015-11-19T16:50:27+00:00

The new hci_skb_pkt_* wrappers are mainly intented for drivers to
require less knowledge about bt_cb(sbk) handling. So after converting
the core packet handling, convert all drivers.

debugfs: Pass bool pointer to debugfs_create_bool()

2015-10-04T10:36:07+00:00

Its a bit odd that debugfs_create_bool() takes 'u32 *' as an argument,
when all it needs is a boolean pointer.

It would be better to update this API to make it accept 'bool *'
instead, as that will make it more consistent and often more convenient.
Over that bool takes just a byte.

That required updates to all user sites as well, in the same commit
updating the API. regmap core was also using
debugfs_{read|write}_file_bool(), directly and variable types were
updated for that to be bool as well.

Bluetooth: hci_qca: Changed unsigned long to bool

2015-09-28T11:06:13+00:00

'retransmit' being set in HCI_IBS_TX_WAKING case, using bool would be
efficient. Initialize local bool to false.
