Ivanov" Date: Thu, 30 Apr 2026 13:52:31 +0300 Subject: [PATCH] arm64: dts: bcm2712: CM5: Ethernet PHY use polling mode This is temporal fix for following kernel error message: ... gpio gpiochip4: (pinctrl-rp1): gpiochip_lock_as_irq: cannot get GPIO direction gpio gpiochip4: (pinctrl-rp1): unable to lock HW IRQ 37 for IRQ genirq: Failed to request resources for 1f00100000.ethernet-ffffffff:00 (irq 158) on irqchip pinctrl-rp1 ... The proper fix, which define IRQ GPIO direction and pull up did not work. Ethernet interface report 'no-carrier'. Signed-off-by: Ivan T.
