Hi, The current main_gpio1 gpio controllers for the am62p and j722s have holes that are not obvious to a user. Add the gpio-reserved-ranges property to the davinci-gpio properties list and add gpio-reserved-ranges to the am62p and j722s device trees. Prevents users from trying to access gpios that don't exist. The holes are taken from the am62p datasheet [1] (Table 5-24) and am67x datasheet [2] (Table 5-27). Patches depend on patch: dt-bindings: gpio: gpio-davinci: Add the gpio-reserved-ranges property [3] [1] https://www.ti.com/lit/ds/symlink/am62p.pdf [2] https://www.ti.com/lit/ds/symlink/am67.pdf [3] https://lore.kernel.org/all/20240809154638.394091-2-j-mcarthur@xxxxxx/ Best, Jared McArthur Jared McArthur (2): arm64: dts: ti: k3-am62p: Add gpio-reserved-ranges for main_gpio1 arm64: dts: ti: k3-j722s: Add gpio-reserved-ranges for main_gpio1 arch/arm64/boot/dts/ti/k3-am62p-main.dtsi | 1 + arch/arm64/boot/dts/ti/k3-j722s-main.dtsi | 1 + 2 files changed, 2 insertions(+) -- 2.34.1
