From: Claudiu Beznea <claudiu.beznea@microchip.com> stable inclusion from stable-v5.10.143 commit 6bbef2694a06cd17c364dcbee30483b2e4a2ce90 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I6D0U6 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- [ Upstream commit addf7efec23af2b67547800aa232d551945e7de2 ] Min and max output ranges of regulators need to satisfy board requirements not PMIC requirements. Thus adjust device tree to cope with this.
