To enable these devices, drivers should upload 15 * firmware blob and send a command to initialize configuration to factory 16 * settings when completing uploading. Then these devices generate bus reset 17 * and are recognized as new devices with the firmware. 18 * 19 * But with firmware version 5058 or later, the firmware is stored to flash 20 * memory in the device and drivers can tell bootloader to load the firmware 21 * by sending a cue. This cue must be sent one time. 22 * 23 * For streaming, both of output and input streams are needed for Firewire 410 24 * and Ozonic. The single stream is OK for the other devices even if the clock 25 * source is not SYT-Match (I note no devices use SYT-Match). 26 * 27 * Without streaming, the devices except for Firewire Audiophile can mix any 28 * input and output. For this reason, Audiophile cannot be used as standalone 29 * mixer. 30 * 31 * Firewire 1814 and ProjectMix I/O uses special firmware. It will be freezed 32 * when receiving any commands which the firmware can't understand. These 33 * devices utilize completely different system to control. It is some 34 * write-transaction directly into a certain address. All of addresses for mixer 35 * functionality is between 0xffc700700000 to 0xffc70070009c. 36 */ 37 38/* Offset from information register */ 39#define INFO_OFFSET_SW_DATE 0x20 40 41/* Bootloader Protocol Version 1 */ 42#define MAUDIO_BOOTLOADER_CUE1 0x00000001 43/* 44 * Initializing configuration to factory settings (= 0x1101), (swapped in line), 45 * Command code is zero (= 0x00), 46 * the number of operands is zero (= 0x00)(at least significant byte) 47 */ 48#define MAUDIO_BOOTLOADER_CUE2 0x01110000 49/* padding */ 50#define MAUDIO_BOOTLOADER_CUE3 0x00000000 51 52#define MAUDIO_SPECIFIC_ADDRESS 0xffc700000000ULL 53 54#define METER_OFFSET 0x00600000 55 56/* some device has sync info after metering data */ 57#define METER_SIZE_SPECIAL 84 /* with sync info */ 58#define METER_SIZE_FW410 76 /* with sync info */ 59#define METER_SIZE_AUDIOPHILE 60 /* with sync info */ 60#define METER_SIZE_SOLO 52 /* with sync info */ 61#define METER_SIZE_OZONIC 48 62#define METER_SIZE_NRV10 80 63 64/* labels for metering */ 65#define ANA_IN "Analog In" 66#define ANA_OUT "Analog Out" 67#define DIG_IN "Digital In" 68#define SPDIF_IN "S/PDIF In" 69#define ADAT_IN "ADAT In" 70#define DIG_OUT "Digital Out" 71#define SPDIF_OUT "S/PDIF Out" 72#define ADAT_OUT "ADAT Out" 73#define STRM_IN "Stream In" 74#define AUX_OUT "Aux Out" 75#define HP_OUT "HP Out" 76/* for NRV */ 77#define UNKNOWN_METER "Unknown" 78 79struct special_params { 80 bool is1814; 81 unsigned int clk_src; 82 unsigned int dig_in_fmt; 83 unsigned int dig_out_fmt; 84 unsigned int clk_lock; 85 struct snd_ctl_elem_id *ctl_id_sync; 86}; 87 88/* 89 * For some M-Audio devices, this module just send cue to load firmware.
