254 * @ucode_api_max: Highest version of uCode API supported by driver.
255 * @ucode_api_min: Lowest version of uCode API supported by driver.
256 * @pa_type: used by 6000 series only to identify the type of Power Amplifier
257 * @need_dc_calib: need to perform init dc calibration
258 * @need_temp_offset_calib: need to perform temperature offset calibration

267 * We enable the driver to be backward compatible wrt API version. The
268 * driver specifies which APIs it supports (with @ucode_api_max being the
269 * highest and @ucode_api_min the lowest). Firmware will only be loaded if
270 * it has a supported API version. The firmware's API version will be
271 * stored in @iwl_priv, enabling the driver to make runtime changes based
272 * on firmware version used.
273 *
274 * For example,
275 * if (IWL_UCODE_API(priv->ucode_ver) >= 2) {
276 *	Driver interacts with Firmware API version >= 2.
277 * } else {
278 *	Driver interacts with Firmware API version 1.
279 * }
280 *
281 * The ideal usage of this infrastructure is to treat a new ucode API
282 * release as a new hardware revision. That is, through utilizing the
283 * iwl_hcmd_utils_ops etc. we accommodate different command structures
284 * and flows between hardware versions (4965/5000) as well as their API
285 * versions.
