The BT host has fixed set of buffers to send data to SoC, generic value
is 5. When a connection, like A2DP playback is ready to send data it
fills one of the buffer available and sends to SoC. Once SoC got
acknowledged from remote side that the data received it updates the host
and the buffer is freed. Till host is acknowledged the send Complete
info, the data buffer is locked for that data transfer. The below is the
example for buffers availability.
Total free Buffers count : 5
Connections : 1
Conn_1 need to send data, picks buf_1 and send to SoC
free Buffers count: 4
Buffers used by Conn_1 : 1
Still Conn_1 has more data to send ....
free Buffers count: 3
Buffers used by Conn_1 : 2
Remote device Ack for buf_1, so 1 buffer is freed, updated state is
free Buffers count : 4
Buffers used by Conn_1 : 1
When there are more ACL connections to transfer data, like one
connection for A2DP playback and one for OPP data transfer, all the data
buffers available with host can be used by any ACL which has ready data
to send. This allows maximum throughputs possibility from host. But the
existing solution has a problem. If one connection has used all the
buffers at a instanace of time, and didnt release (this happens when remote
device doesnt ACK to send) the other connections will not have buffers to
send. In current usecase A2dp data cannot be sent to headset as OPP
connection is lost. The current change is, when there are more
connections the quota for a connection that it can use maximum is
total buffers-1. This allows other connections not to get blocked,
at the same time through puts are not going to dropped.

The current acpuclock-krait driver asserts a constant regulator
current request when a CPU is initialized or inserted, and
removes it when a CPU is hotplug-removed.
Improve on this by allowing the current requests to scale based
on the speed of the CPUs. This allows acpuclock drivers to
factor dynamic power into its current requests, which will
change based on the frequency.
Only msm8974 regulators support current requests, so the cur_ua
column is omitted from the other frequency tables. The 8974
table is populated with pessimistic placeholder currents for now,
until characterization data is available.
