206 | * @fw_name_pre: Firmware filename prefix. The api version and extension | |
207 | * (.ucode) will be added to filename before loading from disk. The | |
208 | * filename is constructed as fw_name_pre<api>.ucode. | |
209 | * @ucode_api_max: Highest version of uCode API supported by driver. | |
210 | * @ucode_api_min: Lowest version of uCode API supported by driver. | |
65b7998a | 211 | * @pa_type: used by 6000 series only to identify the type of Power Amplifier |
415e4993 WYG |
212 | * @max_ll_items: max number of OTP blocks |
213 | * @shadow_ram_support: shadow support for OTP memory | |
a0987a8d RC |
214 | * |
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. | |
221 | * | |
222 | * For example, | |
223 | * if (IWL_UCODE_API(priv->ucode_ver) >= 2) { | |
224 | * Driver interacts with Firmware API version >= 2. | |
225 | * } else { | |
226 | * Driver interacts with Firmware API version 1. | |
227 | * } | |
228 | * | |
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 | |
233 | * versions. | |
