Subject: [PATCH v2 0/4] arm64: dts: meson-g12a: bluetooth fixups

These patches :
- adds the 32khz low power clock to the bluetooth node, since this
clock is needed for the bluetooth part of the module to initialize
- bumps the bus speed to 2Mbaud/s

Changes since v1:
- removed the invalid Fixes tags
- added the reviewed/acked by tags

Neil Armstrong (4):
arm64: dts: meson-g12a-sei510: add 32k clock to bluetooth node
arm64: dts: meson-g12a-x96-max: add 32k clock to bluetooth node
arm64: dts: meson-g12a-sei510: bump bluetooth bus speed to 2Mbaud/s
arm64: dts: meson-g12a-x96-max: bump bluetooth bus speed to 2Mbaud/s

Subject: [PATCH v2 3/4] arm64: dts: meson-g12a-sei510: bump bluetooth bus speed to 2Mbaud/s

Setting to 2Mbaud/s is the nominal bus speed for common usages.

Subject: [PATCH v2 2/4] arm64: dts: meson-g12a-x96-max: add 32k clock to bluetooth node

The 32k low power clock is necessary for the bluetooth part of the
combo module to initialize correctly, simply add the same clock we
use for the sdio pwrseq.
