Detailed Description

Macro Definition Documentation

◆ HPD_IP_DIRECTION

#define HPD_IP_DIRECTION (0)

HPD Input direction is used when sensing HPD output from a monitor.

This is used in applications like video dongles and monitors.

◆ HPD_OP_DIRECTION

#define HPD_OP_DIRECTION (PDSS_CTRL_HPD_DIRECTION)

HPD Output direction is used when driving HPD output to a DP source.

This is used in applications like PD port controllers in PC/Mobile platforms.

◆ HPD_EVENT_MASK

#define HPD_EVENT_MASK (3u)

HPD HW register event mask.

◆ HPD_EVENT_0_POS

#define HPD_EVENT_0_POS (0)

HPD Event 0 bit position.

◆ HPD_EVENT_1_POS

#define HPD_EVENT_1_POS (2)

HPD Event 1 bit position.

◆ HPD_EVENT_2_POS

#define HPD_EVENT_2_POS (4)

HPD Event 2 bit position.

◆ HPD_EVENT_3_POS

#define HPD_EVENT_3_POS (6)

HPD Event 3 bit position.

◆ HPD_GET_EVENT_0

#define HPD_GET_EVENT_0 ( hpd_queue ) (((hpd_queue) >> HPD_EVENT_0_POS) & HPD_EVENT_MASK)

Get the first HPD event from queue status.

◆ HPD_GET_EVENT_1

#define HPD_GET_EVENT_1 ( hpd_queue ) (((hpd_queue) >> HPD_EVENT_1_POS) & HPD_EVENT_MASK)

Get the second HPD event from queue status.

◆ HPD_GET_EVENT_2

#define HPD_GET_EVENT_2 ( hpd_queue ) (((hpd_queue) >> HPD_EVENT_2_POS) & HPD_EVENT_MASK)

Get the third HPD event from queue status.

◆ HPD_GET_EVENT_3

#define HPD_GET_EVENT_3 ( hpd_queue ) (((hpd_queue) >> HPD_EVENT_3_POS) & HPD_EVENT_MASK)

Get the fourth HPD event from queue status.

◆ PDSS_HPD_CTRL1_DEFAULT_VALUE

#define PDSS_HPD_CTRL1_DEFAULT_VALUE (0x80530096UL)

This is the default value to be used for HPD_CTRL1 register.

This value translates to: 0x096: IRQ MIN time (0.25 ms) 0x500: IRQ MAX time (2.2 ms) 0: FLUSH_QUEUE 0: LOOPBACK_EN 1: RESET_HPD_STATE

◆ PDSS_HPD_CTRL3_DEFAULT_VALUE

#define PDSS_HPD_CTRL3_DEFAULT_VALUE (0x0005304BUL)

This is the default value to be used for HPD_CTRL3 register.

This value translates to: STABLE_HIGH = 0x4B (2 ms) STABLE_LOW = 0x53 (2.213 ms)

◆ PDSS_HPDT_CTRL2_DEFAULT_VALUE

#define PDSS_HPDT_CTRL2_DEFAULT_VALUE (0x017BC530UL)

This is the default value to be used for HPDT_CTRL2 register.

This change is brought in to meet the timings mentioned in the display port specification. This value translates to: SET_LOW_DELAY = 0x530 (2.21 ms) SET_HIGH_DELAY = 0x7bc (3.3 ms) DEFAULT_OE = 1
