[PATCH v5 0/2] Cover letter QCC2072 enablement

[PATCH v5 0/2] Cover letter QCC2072 enablement

[Vivek Sahu]

The history of the patch set as follows.
v1: First commit to add support of QCC2072 chipset
v2: resolving review comments to sort the chipset in the switch case
    and other files whenever possible. "qca_btsoc_type" enum in
    drivers/bluetooth/btqca.h contains all the soc type which need to be
    enabled for BT enablement on the target device. There are few places
    where logic of framing packets transferring between SoC  and Host
    depends on the which generation of the chip it is, refer api
    "qca_read_soc_version". So It is not sorted in btqca.h file.
v3: indentation fix and "qcom,wcn3950-bt" is deleted by mistake.
v4: made a separate change for sorting chip name. added new schema
    for qcc2072 dt-bindings
v5: correct dt-bindings commit msg and place QCC2072 to the correct
    order of chip id in the enum.

[PATCH v5 1/2] dt-bindings: bluetooth: qcom,qcc2072-bt: add bindings for QCC2072

[Vivek Sahu]

QCC2072 is a WiFi/BT connectivity radios which exposes
UART as an interface for Bluetooth part.
It requires different configuartions and firmware, so
document it as a new compatible string.

Where are clocks?

Where are supplies?

Interrupt? No, it cannot be interrupt. This can be only enable pin and
then description is redundant. Look at other bindings.

Looks like matching QCA2066, except missing clocks, or like other QCA
devices with proper supplies.

I don't believe that Bluetooth device works without power.

No firmware?

Different configurations like interrupts GPIOs, firmware binaries, 
compat string. Commit msg, I'll correct it in next patch of this commit.

QCC2072 exposes M.2 UART as an interface for Bluetooth part. It doesn't 
require clocks and voltage regulators to power it up.

It is an interrupt to the HOST. I'll make it more comprehensive in the 
next patch of this commit. QCC2072 exposes M.2 UART as an interface for 
Bluetooth part. It doesn't require clocks and voltage regulators to 
power it up.

Firmware is required, it is just I've not added all the fields in the

I asked not what is different but against which this is different.
Different than <here goes explanation>?

Clocks, maybe, but power - I don't believe. AFAIK, sending radio
communication like Bluetooth requires energy. It is BLE, not BNE
(Bluetooth Non Energy)

[PATCH v5 2/2] Bluetooth: qca: add QCC2072 support

[Vivek Sahu]

QCC2072 is a family of WiFi/BT connectivity chip.
It requires different firmware files and has different
configurations , so add it as a separate SoC type.

The firmware for these chips has been recently added to the
linux-firmware repository and will be a part of the upcoming
release.
