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

[Neil Armstrong]

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

[PATCH v2 1/4] arm64: dts: meson-g12a-sei510: add 32k clock to bluetooth node

[Neil Armstrong]

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.

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

[Neil Armstrong]

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