Commit 29075cc09f43 ("arm64: dts: ti: Introduce AM62P5 family of SoCs") introduced the main_gpio1 node and included the ti,ngpio property, but did not include the gpio-reserved-ranges property. As a result, the user could try to access gpios that do not exist. Fix this by introducing the gpio-reserved-ranges property. The non-existent gpios are found in the am62p datasheet [1] in Table 5-24. Depends on patch: dt-bindings: gpio: gpio-davinci: Add the gpio-reserved-ranges property [2] [1] https://www.ti.com/lit/ds/symlink/am62p.pdf [2] https://lore.kernel.org/all/20240809154638.394091-2-j-mcarthur@ti.com/ Signed-off-by: Jared McArthur <j-mcarthur@ti.com> --- arch/arm64/boot/dts/ti/k3-am62p-main.dtsi | 1 + 1 file changed, 1 insertion(+)
