-Subject: [PATCH] brcmfmac: access PMU registers using standalone PMU core if
- available
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-On recent Broadcom chipsets PMU is present as separated core and it
-can't be accessed using ChipCommon anymore as it fails with e.g.:
-[ 18.198412] Unhandled fault: imprecise external abort (0x1406) at 0xb6da200f
-
-Add a new helper function that will return a proper core that should be
-used for accessing PMU registers.
