[PATCH v5 0/7] add support for Bluetooth on MT7622 SoC

[sean.wang]

From: Sean Wang <sean.wang@mediatek.com>

v5 and changes since v4:
 - add Reviewed-by Tag from Ulf Hansson for patch 2.
 - remove default y in Kconfig for btmtkuart selection to avoid overkill for
   users which would like to have less an amount on stuff in kernel.
 - list header declarations in alphabetical order and add a proper blank line
   within.
 - remove unused macro.
 - use sizeof to calculate structure size instead of an aextra macro to hardcode.
 - use struct hci_dev * as input paraments for mtk_hci_wmt_sync and mtk_setup_fw
   for that can be reused in mtk bluetooth with other interfaces.
 - remove unused local variabled in mtk_btuart_recv.
 - remove superfluous :8 for dlen2 in struct mtk_stp_hdr definition.
 - give a reasonable naming for these labels and add a pm_runtime_put_noidle()
   in the path undoing failing pm_runtime_get_sync().
 - Turn __u8 into u8 in struct mtk_stp_hdr.
 - Change coding style for align 80-chars wrap

 Really thanks for these reviews by Johan Hovold and Andy Shevchenko

v4 and changes since v3:
 - refine patch 2 based on commit 919b7308fcc4 to allow that
   dev_pm_domain_attach() will return better error codes. 

v3 and changes since v2
* all changes happen on patch 6
 - fix up SPDX license style for btmtkuart.h.
 - change firmware download from in ACL data to in HCI commands
   and then remove unused mtk_acl_wmt_sync and related code.
 - add a workaround replacing bad vendor event id 0xe4 with 0xff every
   vendor should use.
 - add a sanity check for mtk_hci_wmt_sync to verifying if
   input parameters are valid.
 - add an atomic_inc(&bdev->hdev->cmd_cnt) for __hci_cmd_sync_ev.
 - be changed to use firmware with a header called mt7622pr2h.bin.

v2 and changes since v1
 - Dropped patches already being applied
 - Rewirte the whole driver using btuart [1], and add slight extension
   of btuart to fit into btmtkuart driver. Beware that [1] is also pulled
   into one part of the series for avoiding any breakage when the patchset
   is being compiled.

[1] btuart

v1:

Hi,

This patchset introduces built-in Bluetooth support on MT7622 SoC.
And, it should be simple to make an extension to support other
MediaTek SoCs with adjusting a few of changes on the initialization
sequence of the device.

Before the main driver is being introduced, a few of things about
power-domain management should be re-worked for serdev core and MediaTek
SCPSYS to allow the Bluetooth to properly power up.

Patch 2: add a generic way attaching power domain to serdev
Patch 3 and 4: add cleanups with reuse APIs from Linux core
Patch 5: fix a limitation about power enablement Bluetooth depends on
Patch 1, 6 and 7: the major part of adding Bluetooth support to MT7622

Thanks! I'll remove the words "one of" from the compatible description,
and the extra " being added accidentally.

And the below example fully shows the bluetooth device and its attached
bus (mediatek,mt7622-btif) to let people know clearly how to enable the
bluetooth device.

The current document just describes the bluetooth device and as for the
attached bus, it is already present at
Documentation/devicetree/bindings/serial/8250.txt.

[PATCH v5 2/7] serdev: add dev_pm_domain_attach|detach()

[sean.wang]

From: Sean Wang <sean.wang@mediatek.com>

In order to open up the required power gate before any operation can be
effectively performed over the serial bus between CPU and serdev, it's
clearly essential to add common attach functions for PM domains to serdev
at the probe phase.

Similarly, the relevant dettach function for the PM domains should be
properly and reversely added at the remove phase.

can we take this through the serial subsystem? Or should I just take it when the driver is ready to be included?

I think it's better if the change is taken through serial subsystem
first.

[PATCH v5 3/7] Bluetooth: Add new serdev based driver for UART attached controllers

[sean.wang]

From: Marcel Holtmann <marcel@holtmann.org>

This is a from scratch written driver to run H:4 on serdev based system
with a Bluetooth controller attached via an UART. It is currently tested
on RPi3 and it has Broadcom integration. It is DT only and is missing
GPIO and runtime power management integration. Also Apple or ACPI
support is currently not added.

To integrate with controllers from Intel and Qualcomm, similar handling
like with btusb.c has to be done. A simple abstraction for that has been
provided to make it similar to hci_uart.

The goal is to run individual drivers on serdev capable systems so that
we can retire hci_uart on these system and continue with a lot simpler
and easier to maintain driver. It seems that hci_uart has too many race
conditions due to handling TTY and line disciplines. And fixes for that
are not really related to serdev based drivers. In a serdev only world
it makes sense to remove any of the complex code.

[PATCH v5 5/7] Bluetooth: Extend btuart driver for join more vendor devices

[sean.wang]

From: Sean Wang <sean.wang@mediatek.com>

Adding an independent btuart.h header allows these essential definitions
can be reused in vendor driver. Also, struct btuart_vnd is extended with
additional callbacks such as .init initializing vendor data, .shtudown,
.recv and .send supporting SoC specific framing for that btuart can
simply adapt to various Bluetooth uart-based devices.

I really like to avoid this since it is not clean. Frankly I prefer to keep the btuart.c driver for drivers that really just use H:4 as transport protocol. If the protocol is only H:4 alike and has extra headers, then it should be a separate driver.

The common H:4 handling is abstracted in h4_recv.h already anyway and we can add more pieces if needed. However I also wonder since you have extra framing that the complex H:4 state keeping might be not needed at all. So it could be simplified.

thanks for letting me know your concern. I think I'm a little over in reusing these existing methods and break something generic and its beauty.

I'll make the driver be a separate one based on btuart in the next version.

okay, I will get rid of h4_recv.h and consider to use more simplified logic to handle the extra framing and its payload.

only if it is already framed by your extra header, but I seem to recall that it will frame it. For example the bfusb.c old driver does frame H:4 as well and then no extra state keeping for H:4 is needed. Just pass the frames up into the core via hci_recv_frame (or hci_recv_diag for vendor diagnostic) and move on with it.

You can of course use h4_recv.h if you need to, but only do that if you are true H:4 stream and have no idea where a frame ends and starts.

Thanks for the explanation, I didn't show what the extra header is, that causes some misunderstanding.

The mtk extra header doesn't provide any idea where a frame ends and starts in the bluetooth stream. 

It is just totally a legacy stuff used by mtk combo devices sharing a serial transport, such as BT/GPS/FM running via a shared UART, to
let the host know what type of radio the following bytes is for and how long it's. 

The extra header is really useful for a combo device, splitting flow and fitting in a single serial transport, but for a single device such as
mt7622 Bluetooth I made here, it seems to be useless.

Because the extra header doesn't provide any details about this stream and each radio stack still needs to be in charge of their stream
parsing. That is why I still want to use recv_h4.h instead of coding my own parser.

but that means it is framed. You know ahead of time how long the H:4 packet will be. That is the important part. Unless you tell me that it can fragment a H:4 frame over multiple MTK specific frames.

> The extra header is really useful for a combo device, splitting flow and fitting in a single serial transport, but for a single device such as

Useless or not depends on what you are going to do with the device. In theory you could write a serdev driver that just handles the multiplexing (since that is what you have) and then hands down the frames to individual drivers. Frankly something like btqcomsmd.c seems to be what you really want here. However first you would needed this multiplex driver that takes the serial stream and breaks it up.

> Because the extra header doesn't provide any details about this stream and each radio stack still needs to be in charge of their stream

As I said above, if the header + length always indicates a full H:4 frame, then you do not need h4_recv.h since you know the packet size. If it doesn't (and it means things can fragment), then you do.

However I have to note that a serial stream from your multiplexer protocol also needs some state handling since it can be interrupted at any point. If you want this clean, then you actually do that anyway. Essentially you have two protocols layered and want to process the independently.

If you post details about the multiplexing protocol for your serial stream, then I can help you design a driver for it. With serdev that is actually simple. And then you could hook up GPS etc. at some point once you want to run this on hardware that has the combo chip.

Having a Linux Bluetooth driver is useful for Android as well btw. We have HCI_CHANNEL_USER and a generic Android driver for using it. So enabling the chip in Linux upstream will enable it for Android as well.

My case is the extra header + length doesn't indicate a full H:4 frame,
things can fragment

Yes, I also agree that it makes better and cleaner if there is another
driver in charge of the multiplexer protocol and the framing.

But, could you accept that I postpone the target into the next stage,
I just like to consider BT single device, not for multiplexer protocol
case, in the current stage.

To be honest, my next step is to add mt7688 btusb and then want to have
an integration with btmtkuart. mt7688 btusb doesn't have extra framing
for multiplexer protocol, so it can allow me to make the concentration
more on pure bt protocol and pushing the latest mtk bluetooth devices
being supported on the bluez driver.

okay, really thanks for your help. I also have an interest on this part.
now how does bluez receive and sent packet from/to a virtual device ( a
serdev handling multiplexer protocol)? It seems current bluez device all
handling packet from/to physical bus device. or I was missing something?

it really save more time as I knew many vendors do two driver separately
for bluez and bluedroid. where could I find the resource for
HCI_CHANNEL_USER and generic android driver ? Is it still the part of
bluez or run by another project ?

[PATCH v5 6/7] Bluetooth: mediatek: Add protocol support for MediaTek serial devices

[sean.wang]

From: Sean Wang <sean.wang@mediatek.com>

This adds a driver to run on the top of btuart driver for the MediaTek
serial protocol based on running H:4, which can enable the built-in
Bluetooth device inside MT7622 SoC.

From: Sean Wang <sean.wang-NuS5LvNUpcJWk0Htik3J/w@public.gmane.org>

Add a new quirk HCI_QUIRK_NON_PERSISTENT_SETUP allowing that a quirk that
runs setup() after every open() and not just after the first open().

can you include the extract of btmon on how the HCI_DEV_SETUP event shows up in the traces? I remember that I asked about something like that.

No, I cannot see any event about HCI_DEV_SETUP in btmon trace, the trace I posted as below is doing some rounds of power off and then on

it will result in this:

        case HCI_DEV_SETUP:
                if (hdev->manufacturer == 0xffff)
                        return NULL;
                                                                                 
        case HCI_DEV_UP:
                skb = bt_skb_alloc(HCI_MON_INDEX_INFO_SIZE, GFP_ATOMIC);

So we will see extra index info events, but I assume that is just fine this we also see them on DEV_UP. They also do not hurt as long as not magically the manufacturer information changes.

I do wonder though if this quirk is set, then hdev->manufacturer needs to be reset and allow hdev->setup() to reset it. This goes with a log of other information as well. Maybe just a look if there are no races here.

Regards

Marcel

I didn't set a value to hdev->manufacture.

Should I set it in hdev->setup() ? MediaTek is 0x46 according to [1].

sorry, something needs be corrected.

what I means is that should I set hdev->manufacture as 0x46 at probe ?

it is generally useful so that it gets reported out in btmon and thus it can assign the correct vendor specific decoder. However you better set hdev->manufacturer = 70 in the probe() routine before calling hci_register_dev. You have a dedicated driver and thus will always know it.

The core tries to figure this out at some point, but then you are missing btmon decoding for the earlier messages. See btusb.c and how other drivers set it early on.

thank for the point up, I will set hdev->manufacturer as 70 in probe
routine before calling hci_register_dev in the next version.
