Port driver passes this - * driver information to display driver as part of registering itself with - * display driver. pd_register(pd_driver_t *) is called from port driver - * in its init function which is called whenever port driver is loaded. - * - * Port driver provides following list of functions to display driver. - * Display driver calls these functions to do the required operations. - * - * type - supporting display type for the port driver - * - * flags - flags for the driver. And cannot be changed at runtime. - * Once these flags are passed to main driver, they will be - * used while setting the mode. - * - * context - Driver's contextual information. The driver can save - * all needed state information in this opaque pointer - * such that the driver is entirely reentrant. No writeable - * data may be saved in any non-stack variables by a driver - * therefore all necessary data must be saved in a private - * structure and stored in this pointer. This pointer is - * passed to the driver with each function call. - * - * validate - Display driver calls this function to validate the port - * driver by passing a magic cookie. Port driver does some - * magic operation and returns another cookie back to caller. - * If the returned cookie has correct value then the driver - * passes the validation, otherwise driver cannot communicate - * with display driver. - * - * open - This function is to detect for any port device (codec). - * pd_callback_t has all the required callback functions - * to do this operation. - * - * init_device - This function detects and initializes any display devices - * attached to the codec. - * - * For ex: a multi function encoder can support a FlatPanel or - * TVout display. It has to detect and check for any - * Flatpanel or TVout display device attached, then it - * initializes the display devices. - * - * pd_close - closes the display device and frees any memory allocated. - * - * set_mode - sets/tests a mode. Display (or main) driver calls this - * function to set a mode when the encoder in D3 power state. - * At this time, DVO timings are off. - * If encoder wants to run setmode in any other power state, - * then first thing it needs to do is enter into that power - * state and then do setmode. - * - * When this function returns it is expected that: - * 1. Either encoder is in D0 power state or - * it defers until post_set_mode(). - * 2. In case of external encoder (example: TVOut encoder) - * driving the reference clock, the clock is running. - * - * post_set_mode- This is called after GMCH DVO timings are on. - * This function can be null if there is nothing to do. - * This is used to do any post processing on the encoder - * after GMCH starts driving the timings. When this function - * returns it is expected that the encoder is in D0 power state. - * Parameters: - * context - port driver context - * mode - current timing - * flags - not used (for future use). - * - * set_attrs - to set provided list of attributes. - * - * get_attrs - to get list of attributes. - * - * get_timing_list - returns the list of supported modes for the current - * attributes. For example if the TVFormat is NTSC, this - * function will return only the modes supported for NTSC. - * - * set_power - to set the power state of the display device. - * - * get_power - to get the current power state of the display device. - * - * pd_save - to save the current state of the registers. - * - returns the current state in the double pointer 'state'. - * - * pd_restore - to restore to the passed state. This functions frees the - * resources allocated that state. - * - pass the previously saved state in 'state'. - * - * If PD_NO_RESTORE_FREE_STATE is set, then it just frees - * the resources without restoring the state. - * - * pd_get_port_status - to get the status of port/display - * - * - * All functions return value: - * == 0 - if success - * != 0 - if failure - */ - - -/* Note on version AA.BB.CC.DD - * AA - Major version - * BB - Minor version - * CC - Patch version if any - * DD - Bug fixes if any - * - * 01.00.00.00 is the first initial major version */ -typedef struct _pd_version { - unsigned char major; - unsigned char minor; - unsigned char patch; - unsigned char bug_fix; -} pd_version_t; - - -typedef enum { - PD_DISP_STATUS_DETACHED = 0, /* Display is not connected */ - PD_DISP_STATUS_ATTACHED, /* Display is connected */ - PD_DISP_STATUS_UNKNOWN /* Unable to determine */ -} pd_display_status_t; - -/* Port/Display information */ -typedef struct _pd_port_status { - pd_display_status_t connected; /* Display status */ - unsigned long display_type; /* Type of display, if connected */ -} pd_port_status_t; - -typedef struct _pd_driver { - unsigned long pd_sdk_version; /* PD SDK version - interface ver */ - char name[PD_NAME_SIZE]; /* Descriptive name of port driver */ - char num_devices; /* Number of devices it is driving */ - pd_version_t *version; /* Driver version */ - unsigned long type; - unsigned long flags; - unsigned long *dab_list; /* PD_DAB_LIST_END terminated list */ - unsigned long i2c_speed; /* Encoder I2C speed in KHz */ - unsigned long (*validate)(unsigned long cookie); - int (*open) (pd_callback_t *callback, void **context); - int (*init_device)(void *context); - int (*pd_close) (void *context); - int (*set_mode) (void *context, pd_timing_t *mode, unsigned long flags); - int (*post_set_mode)(void *context, pd_timing_t *mode, unsigned long flags); - int (*set_attrs) (void *context, unsigned long num, pd_attr_t *list); - int (*get_attrs) (void *context, unsigned long *num, pd_attr_t **list); - int (*get_timing_list)(void*context,pd_timing_t*in_list,pd_timing_t**list); - int (*set_power) (void *context, unsigned long state); - int (*get_power) (void *context, unsigned long *state); - int (*pd_save) (void *context, void **state, unsigned long flags); - int (*pd_restore) (void *context, void *state, unsigned long flags); - int (*pd_get_port_status) (void *context, pd_port_status_t *port_status); -} pd_driver_t; - -/* Mode filter helper function for port drivers */ -/* Structure representing encoder capabilities for mode filtering */ -typedef struct _pd_dvo_info { - unsigned long min_dclk; /* Min clock */ - unsigned long max_dclk; /* Max clock */ - unsigned char upscale; /* Is upscalable? */ - unsigned char downscale; /* Is downscalable? */ - unsigned short upscale_min_width; /* Min upscale width */ - unsigned short upscale_min_height; /* Min upscale height */ - unsigned short downscale_max_width; /* Max downscale width */ - unsigned short downscale_max_height; /* Max downscale height */ -} pd_dvo_info_t; - -typedef struct _pd_display_info { - unsigned char panel_fit; /* Incoming */ - unsigned char fixed_res; /* Outgoing */ - unsigned short width; /* Outgoing */ - unsigned short height; /* Outgoing */ - pd_timing_t *native_dtd; /* Outgoing */ -} pd_display_info_t; - -/* All following functions are provided to port drivers as a binary file. - * - * pd_register: This function is called by port driver to register with - * display driver.
