** Description changed: SRU Justification [Impact] When EDATEC Pi CM5 devices with 7-inch screens resume from screen off, a white glow appears around the screen for around 5 seconds before disappearing. EDATEC determined this to be caused by a backlight power state restoration bug. [Fix] Pull the fix from upstream Raspberry Pi tree (rpi-7.0.y branch): - - 25a3352a71be3 regulator: edatec-panel-regulator: Fix backlight power state restoration + - ab523ceeb3599 regulator: edatec-panel-regulator: Fix backlight power state restoration [Test Plan] * Compile tested * Boot tested * No impacts to existing features found Install the built packages and the correct config.txt, reboot the machine and the 7" display should no longer display a white glow when the screen lights up. [Regression potential] Relatively low, as change is a bug fix from upstream.
