[PATCH v3 0/2] Add BCM43752 chipset support

The SparkLan AP6275 SDIO M.2 card contains a BCM43752 based module and these
patches were tested with that card.

This was tested on the 5.13 kernel with a minor substition BRCMF_FW_DEF for
BRCMF_FW_CLM_DEF.

It should apply and build on the wireless-next branch.

Changes since v2:

Squashed patches 1 and 2.
Fixed bluetooth patch subject.

Changes since v1:

Add bluetooth patchram definition

Angus Ainslie (2):
  brcmfmac: add 43752 SDIO ids and initialization
  btbcm: add patch ram for bluetooth

seems I missed that part. Can you look internally what this hardware is and we fix it?

I will check although not internally as this is probably a Cypress chipset. 
Anyway, I will follow up on this.

Add HW and SDIO ids for use with the SparkLan AP6275S
Add the firmware mapping structures for the BRCM43752 chipset.
The 43752 needs some things setup similar to the 43012 chipset.
The WATERMARK shows better performance when initialized to the 4373 value.
