Commit ed07d82f9e3e8 ("arm64: dts: ti: k3-am62p-j722s: Move
SoC-specific node properties") 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 am67x datasheet [1] in Table
5-27.
Depends on patch: dt-bindings: gpio: gpio-davinci: Add the
gpio-reserved-ranges property [2]
