dt-bindings: net: qcom,ipa: add firmware-name property
Add a new optional firmware-name property to the IPA DT node. It is used only if the modem is not doing early initialization (i.e., if the modem-init property is not present). Its value is the name of the firmware file to use; if it's not specified, a default name ("ipa_fws.mdt") is used. Signed-off-by: Alex Elder <elder@linaro.org> Signed-off-by: David S. Miller <davem@davemloft.net>
