206 * @fw_name_pre: Firmware filename prefix. The api version and extension

212 * @max_ll_items: max number of OTP blocks

215 * We enable the driver to be backward compatible wrt API version. The
216 * driver specifies which APIs it supports (with @ucode_api_max being the
217 * highest and @ucode_api_min the lowest). Firmware will only be loaded if
218 * it has a supported API version. The firmware's API version will be
219 * stored in @iwl_priv, enabling the driver to make runtime changes based
220 * on firmware version used.
223 * if (IWL_UCODE_API(priv->ucode_ver) >= 2) {
224 * Driver interacts with Firmware API version >= 2.
226 * Driver interacts with Firmware API version 1.
229 * The ideal usage of this infrastructure is to treat a new ucode API
230 * release as a new hardware revision. That is, through utilizing the
231 * iwl_hcmd_utils_ops etc. we accommodate different command structures
232 * and flows between hardware versions (4965/5000) as well as their API
