infineon,hppass-ac-state

Description

Infineon HPPASS Autonomous Controller (AC) State Transition Table entry.

Each node with this compatible represents one state in the AC State Transition
Table (STT).  The node is referenced by phandle from the parent HPPASS
device's ac-states property, which determines the state's index in the table.

This binding covers all STT fields: AC core, GPIO output, CSG (×5 slices),
SAR, and SAR MUX (×4 channels).  All properties default to 0, so only the
fields relevant to a particular state need to be specified.

Use constants from <dt-bindings/mfd/infineon-hppass.h> for condition,
action, GPIO output, and SAR group mask values.

Properties

Properties not inherited from the base binding file.

Name

Type

Details

ac-condition

int

 
AC condition code. Use IFX_HPPASS_AC_COND_* constants
from <dt-bindings/mfd/infineon-hppass.h>.
Default: FALSE (0).

Default value: 0

ac-action

int

 
AC action code. Use IFX_HPPASS_AC_ACTION_* constants
from <dt-bindings/mfd/infineon-hppass.h>.
Default: STOP (0).

Default value: 0

branch-state-idx

int

 
Branch target state index (0-15) within the ac-states list.
Used when the action is BRANCH_IF_TRUE or BRANCH_IF_FALSE.

Default value: 0

ac-interrupt

int

 
Interrupt/trigger flag (0 or 1).
When set to 1, a pulse trigger or CPU interrupt is generated
on entering this state (or after the wait condition is met for
WAIT_FOR actions).

Default value: 0

ac-count

int

 
Timer/counter value (1-4096).
For WAIT_FOR actions this is an interval timer.
For BRANCH_IF_* actions this is a loop counter.
A value of 0 disables the timer/counter for this state.

Default value: 0

gpio-out-unlock

int

 
GPIO output unlock flag (0 or 1).
When 1, GPIO output mask is applied in this state.

Default value: 0

gpio-out-msk

int

 
GPIO output mask. Use IFX_HPPASS_GPIO_OUT_* constants
from <dt-bindings/mfd/infineon-hppass.h>.
Can be OR'd for multiple outputs (e.g., GPIO_OUT_0 | GPIO_OUT_1).

Default value: 0

csg2-enable

int

 
CSG slice 2 enable flag (0 or 1). Requires csg2-unlock = 1.

Default value: 0

csg2-dac-trig

int

 
CSG slice 2 DAC start/update trigger flag (0 or 1).

Default value: 0

csg3-unlock

int

 
CSG slice 3 unlock flag (0 or 1).

Default value: 0

csg3-enable

int

 
CSG slice 3 enable flag (0 or 1). Requires csg3-unlock = 1.

Default value: 0

csg3-dac-trig

int

 
CSG slice 3 DAC start/update trigger flag (0 or 1).

Default value: 0

csg4-unlock

int

 
CSG slice 4 unlock flag (0 or 1).

Default value: 0

csg4-enable

int

 
CSG slice 4 enable flag (0 or 1). Requires csg4-unlock = 1.

Default value: 0

csg4-dac-trig

int

 
CSG slice 4 DAC start/update trigger flag (0 or 1).

Default value: 0

sar-unlock

int

 
SAR unlock flag (0 or 1).
When 1, SAR enable state is applied in this state.

Default value: 0

sar-enable

int

 
SAR enable flag (0 or 1). Requires sar-unlock = 1.
Normally used with WAIT_FOR + BLOCK_READY condition.

Default value: 0

sar-grp-msk

int

 
SAR sequencer group trigger mask. Use IFX_HPPASS_SAR_GRP_* constants
from <dt-bindings/mfd/infineon-hppass.h>.
Can be OR'd for multiple groups. Effective when SAR is enabled
and SAR group trigger source is set to AC.
