Subject: [PATCH 0/2] arm64: dts: ti: k3-am62p/j722s: Add gpio-reserved-ranges for main_gpio1

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]
