Bluetooth: btintel_pcie: Fix incorrect MAC access programming

2026-05-20T20:35:47+00:00

btintel_pcie_get_mac_access() and btintel_pcie_release_mac_access() were programming STOP_MAC_ACCESS_DIS and XTAL_CLK_REQ in addition to the MAC_ACCESS_REQ handshake. These bits are not part of the host MAC-access handshake on the supported parts; the driver was programming them incorrectly. Drop the writes so the register update contains only the bits the controller actually consumes.

Bluetooth: btintel_pcie: treat boot stage bit 12 as warning

2026-05-06T20:21:34+00:00

CSR boot stage register bit 12 is documented as a device warning, not a fatal error. Rename the bit definition accordingly and stop including it in btintel_pcie_in_error(). This keeps warning-only boot stage values from being classified as errors while preserving abort-handler state as the actual error condition.

Bluetooth: btintel_pcie: use strscpy to copy plain strings

Bluetooth: btintel_pcie: Align shared DMA memory to 128 bytes

2026-04-13T13:19:42+00:00

Align each descriptor/index/context region to 128 bytes before calculating the total DMA pool size. This ensures the memory layout shared with firmware meets the 128-byte alignment requirement. The DMA pool alignment is also set to 128 bytes to match the firmware expectation for all shared structures. Signed-off-by: Kiran K Signed-off-by: Luiz Augusto von Dentz
