2021-09-09Add WLAN card supportScott Murray1-0/+26
This is loosely based on the contents of the tar file provided with the WLAN cards (AGL_Refhw_sample_software_KK_20210225.tar.gz) with updates for BSP v4.7.0 and other fixes. Changes: - Kernel patches and configuration update to enable the TI WL1837 module. As opposed to the original changes from Panasonic or the Kingfisher support, the HCI LL driver is used instead of the older ti-st + btwilink combination, since the the latter are deprecated and are removed in kernel 5.5. - As part of the above the sound configuration in the devicetree has been reworked to support the WL1837 BT audio. This includes dropping the HDMI1 audio configuration from the original Salvator-X devicetree, as it conflicts with the SSI used for the ak4613 in the reference hardware. - Recipes added for wlconf (from meta-ti) and ti-bt-firmware (loosely derived from the meta-rcar-gen3-adas version). The TI-TFL license used by ti-bt-firmware has been added in a top-level "licenses" directory and that added to LICENSE_PATH in layer.conf to satisfy the license packaging QA checking.
