Expand the firmware-name property to specify the names of NVM and rampatch firmware to load. This update will support loading specific firmware (nvm and rampatch) for certain chips, like the QCA6698 Bluetooth chip, which shares the same IP core as the WCN6855 but has different RF components and RAM sizes, requiring new firmware files. We might use different connectivity boards on the same platform. For example, QCA6698-based boards can support either a two-antenna or three-antenna solution, both of which work on the sa8775p-ride platform. Due to differences in connectivity boards and variations in RF performance from different foundries, different NVM configurations are used based on the board ID. So In firmware-name, if the NVM file has an extension, the NVM file will be used. Otherwise, the system will first try the .bNN (board ID) file, and if that fails, it will fall back to the .bin file. Possible configurations: firmware-name = "QCA6698/hpnv21.bin", "QCA6698/hpbtfw21.tlv"; firmware-name = "QCA6698/hpnv21", "QCA6698/hpbtfw21.tlv"; firmware-name = "QCA6698/hpnv21.bin"; Acked-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org> Signed-off-by: Cheng Jiang <quic_chejiang@quicinc.com> Signed-off-by: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
