1. NAME

drm_helper_probe_single_connector_modes - get complete set of display modes

2. SYNOPSIS

int drm_helper_probe_single_connector_modes(struct drm_connector *  connector , uint32_t  maxX , uint32_t  maxY );

3. ARGUMENTS

connector
    connector to probe

maxX
    max width for modes

maxY
    max height for modes

4. LOCKING

Caller must hold mode config lock.

Based on the helper callbacks implemented by connector try to detect all valid modes. Modes will first be added to the connectorAqs probed_modes list, then culled (based on validity and the maxX, maxY parameters) and put into the normal modes list.

Intended to be use as a generic implementation of the ->probe connector callback for drivers that use the crtc helpers for output mode filtering and detection.

5. RETURNS

Number of modes found on connector.
