Subject: dt-bindings: iio: adc: Remove the property "aspeed,trim-data-valid"
From: Billy Tsai <billy_tsai@xxxxxxxxxxxxxx>
commit 398e3479874f381cca8726ca5d8a31e1bf35a3cd upstream.
If the property is set on a device without valid trimming data in the OTP
the ADC will not function correctly. Therefore, this patch drops the use
of this property to avoid this scenario.
