[PATCH 0/2] bluetooth: mt7921s: Add binding and fixup existing dts

[PATCH 0/2] bluetooth: mt7921s: Add binding and fixup existing dts

[Chen-Yu Tsai]

Hi everyone,

This short series adds a binding document for the MT7921S SDIO Bluetooth
controller. The MT7921S is a SDIO-based WiFi/Bluetooth combo. WiFi and
Bluetooth are separate SDIO functions. The chip has extra per-subsystem
reset lines that can reset only WiFi or Bluetooth cores.

Patch 1 documents the SDIO function and the reset line, based on
existing device tree and driver usage. I listed Sean Wang, the original
driver author and maintainer, as the maintainer of the binding.

Patch 2 fixes up the sole existing usage of the compatible string by
making it a proper SDIO function node.

Please take a look. Not sure which tree patch 1 should be merged
through? I suppose with proper acks it could go through the soc/mediatek
tree together with patch 2.


Regards
ChenYu

[PATCH 1/2] dt-bindings: net: bluetooth: Add MediaTek MT7921S SDIO Bluetooth

[Chen-Yu Tsai]

The MediaTek MT7921S is a WiFi/Bluetooth combo chip that works over
SDIO. While the Bluetooth function is fully discoverable, the chip
has a pin that can reset just the Bluetooth side, as opposed to the
full chip. This needs to be described in the device tree.

Add a device tree binding for MT7921S Bluetooth over SDIO specifically
ot document the reset line.

The function itself is fully probable and the implementation doesn't make
use of the WiFi's reset line, so I don't see any reason to describe it?
I don't actually know what the reset line does in the chip hardware.
This patch is just described what is already used.

Otherwise this looks better. Thanks.

Eh yes, sorry - I edited that statement multiple times and that "for" stuck

[PATCH 2/2] arm64: dts: mediatek: mt8183-pico6: Fix bluetooth node

[Chen-Yu Tsai]

Bluetooth is not a random device connected to the MMC/SD controller. It
is function 2 of the SDIO device.

Fix the address of the bluetooth node. Also fix the node name and drop
the label.
