Subject: [PATCH v12 2/2] Bluetooth: hci_qca: Add support for Qualcomm Bluetooth SoC QCA2066

This patch adds support for QCA2066 firmware patch and NVM downloading.
as the RF performance of QCA2066 SOC chip from different foundries may
vary. Therefore we use different NVM to configure them based on board ID.

Thanks for adding the changelog.

You should also add a sentence or two here that describes what the
series does (e.g. just say "This series adds support for ...").

Also make sure to run scripts/get_maintainer.pl on your series. Looks
like you're still missing some maintainers on CC.

You also did not CC at least on person providing review feedback on
earlier versions.

This is not detailed enough for a changelog, but ok, let's forget about
v2-v9 this time, but remember it for your future submissions.

As I mentioned elsewhere, these Subjects should be distinct and
summarise what each patch does.
