sdm660-common: Chown light nodes earlier The hal class is essentially triggered from the boot class, so it's possible that the HAL starts before the permissions are set, and manual intervention was added to deal with the issue. However, we can simply move chown to an earlier stage to avoid playing with the workflow. Change-Id: I189b247576151f76efaf26b2d266564dc7768fba 2021-04-05 04:04:08 -04:00			`on early-boot`

sdm660-common: Improve lights HAL * Use libbase logging and file utils * Read max brightness from sysfs * Convert constants to constexpr * Move helper functions to anonymous namespace * Bug fixes * Remove redundant chmod * Start the service after permissions are set up because it reads max brightness in constructor.

wayne-common: light: Mark as shutdown critical Required because the lights need to be turned off late in boot (e.x. during fsck for disk health), and before, blank_screen accessing light encountered a race condition where if it didn't get scheduled before all of the processes which were getting shutdown were getting killed, the screen wouldn't blank. Bug: 74976325 Test: adjusting brightness continues to work Test: screen blanks during shutdown at the correct time including when an artificial 5s delay is inserted when the phone normally fscks (which can also be quick) Change-Id: I57ebc11d7ecf57ee327c681455712f4b53de6fd3 2018-03-16 13:23:14 -04:00			`shutdown critical`
