[PATCH v2 0/1] ARM: dts: rockchip: Add brcm bluetooth for rk3288-veyron

[Abhishek Pandit-Subedi]

Hi Heiko,

The necessary patches for this change have been merged into
bluetooth-next. Please pick this up at your convenience.

This patch enables using the Broadcom HCI UART driver with the
BCM43540 Wi-Fi + Bluetooth chip. This chip is used on a RK3288 based
board (Veyron) and these changes have been tested on the Minnie variant
of the board (i.e. rk3288-veyron-minnie.dts).

The changes are applicable to the minnie, mickey, speedy and brain
variants (all of which use the Broadcom chips). The bt-activity node was
removed for all Veyron boards and shouldn't affect the boards using
Marvell chips since they aren't using this out-of-band wakeup gpio.

A previous portion of this series adding the compatible string to the
hci_bcm driver has already been merged into bluetooth-next:
https://lore.kernel.org/r/4680AA6A-599F-4D5E-9A96-0655569BAE94@holtmann.org

Another patch series to fix up the baudrate settings and configure the
PCM parameters has meen merged on bluetooth-next:
https://lore.kernel.org/linux-bluetooth/20191127071105.GA32820@akivisil-mobl1.ger.corp.intel.com/T/#t

Thanks
Abhishek

Changes in v2:
- Changed sco routing params to brcm,bt-pcm-int-params

[PATCH v2 1/1] ARM: dts: rockchip: Add brcm bluetooth for rk3288-veyron

[Abhishek Pandit-Subedi]

This enables the Broadcom uart bluetooth driver on uart0 and gives it
ownership of its gpios. In order to use this, you must enable the
following kconfig options:
- CONFIG_BT_HCIUART_BCM
- CONFIG_SERIAL_DEV

This is applicable to rk3288-veyron series boards that use the bcm43540
wifi+bt chips.

As part of this change, also refactor the pinctrl across the various
boards. All the boards using broadcom bluetooth shouldn't touch the
bt_dev_wake pin.

Doug wanted to give a Reviewed-by, once the underlying bluetooth
changes got merged - not sure what the status is though.

I have been out for the last week and am a bit backlogged.

I notice that this landed in our 4.19 kernel with +Matthias's
Reviewed-by at <https://crrev.com/c/1772261>.  I don't feel any need
to re-review this myself if Matthias has taken a final look on it, so
unless he knows a reason why it shouldn't land then I'd say go ahead
and land it.
