ARM: dts: gpio-ranges property is now required
Since [1], added in 5.7, the absence of a gpio-ranges property has prevented GPIOs from being restored to inputs when released. Add those properties for BCM283x and BCM2711 devices. [1] commit 2ab73c6d8323 ("gpio: Support GPIO controllers without pin-ranges") Link: https://lore.kernel.org/r/20220104170247.956760-1-linus.walleij@linaro.org Fixes: 2ab73c6d8323 ("gpio: Support GPIO controllers without pin-ranges") Fixes: 266423e60ea1 ("pinctrl: bcm2835: Change init order for gpio hogs") Reported-by: Stefan Wahren <stefan.wahren@i2se.com> Reported-by: Florian Fainelli <f.fainelli@gmail.com> Reported-by: Jan Kiszka <jan.kiszka@web.de> Signed-off-by: Phil Elwell <phil@raspberrypi.com> Acked-by: Florian Fainelli <f.fainelli@gmail.com> Reviewed-by: Linus Walleij <linus.walleij@linaro.org> Link: https://lore.kernel.org/r/20211206092237.4105895-3-phil@raspberrypi.com Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Acked-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: Olof Johansson <olof@lixom.net>
