Bluetooth: HCI: Invert LE State quirk to be opt-out rather then opt-in

2024-08-29T15:35:55+00:00

[ Upstream commit aae6b81260fd9a7224f7eb4fc440d625852245bb ]

This inverts the LE State quirk so by default we assume the controllers
would report valid states rather than invalid which is how quirks
normally behave, also this would result in HCI command failing it the LE
States are really broken thus exposing the controllers that are really
broken in this respect.

Current flow iterates the ACPI table associated with Bluetooth
controller looking for PPAG method. Method name can be directly passed
to acpi_evaluate_object function instead of iterating the table.

Bluetooth: Populate hci_set_hw_info for Intel and Realtek

2024-05-14T14:51:05+00:00

The hardware information surfaced via debugfs might be usable by the
userspace to set some configuration knobs. This patch sets the hw_info
for Intel and Realtek chipsets.

Below are some possible output of the hardware_info debugfs file.

Bluetooth: btintel: Add support to download intermediate loader

2024-05-14T14:51:03+00:00

Some variants of Intel controllers like BlazarI supports downloading of
Intermediate bootloader (IML) image. IML gives flexibility to fix issues as its
not possible to fix issue in Primary bootloader once flashed to ROM. This patch
adds the support to download IML before downloading operational firmware image.
