media: lirc: increase IR_MAX_DURATION to send extended code sequences
sensor:increase IR_MAX_DURATION to 1000ms
to fix long IR remote timeouts Certain infrared remotes
(e.g., brand-specific smart home remotes, custom consumer electronics)
send extended code sequences that exceed the default 500ms
IR_MAX_DURATION threshold. This causes the kernel's raw
IR driver to discard incomplete code, resulting in unrecognized commands.
Increase IR_MAX_DURATION to 1000ms:
- Aligns with common extended IR protocol specs
(most long sequences use 700-900ms)
- No impact on standard remotes
(all mainstream IR codes are <500ms)
- Validated on vivo X200 and vivo X300,
resolves timeout issues without regressions
