Hi, I tried to upgrade my OMAP1 OSK board to v5.9, but the rootfs cannot be accessed anymore due to broken USB. It fails to probe with the following logs: [ 9.219940] ohci ohci: cannot find GPIO chip i2c-tps65010, deferring [ 9.250366] ohci ohci: cannot find GPIO chip i2c-tps65010, deferring [ 9.731445] ohci ohci: cannot find GPIO chip i2c-tps65010, deferring [ 10.342102] ohci ohci: cannot find GPIO chip i2c-tps65010, deferring [ 10.966430] ohci ohci: cannot find GPIO chip i2c-tps65010, deferring Bisected to: commit 15d157e874437e381643c37a10922388d6e55b29 Author: Linus Walleij <linus.walleij@xxxxxxxxxx> Date: Mon Jul 20 15:55:24 2020 +0200 usb: ohci-omap: Convert to use GPIO descriptors I suspect one of the issues is the name "i2c-tps65010" vs "tps65010": # cat /sys/devices/platform/omap_i2c.1/i2c-1/i2c-tps65010/gpio/gpiochip208/label tps65010 However changing that in the lookup table still doesn't help much; I got rid of the "deferring" message but the USB still doesn't work. So far the only workaround I have is to revert the whole commit. A.
