commit d85eed9f576369bc90322659de96b7dbea1f9a57 upstream.
Meson8 and Meson8b do not have the MESON_SAR_ADC_REG11 register. The
bandgap setting for these SoCs is configured in the
MESON_SAR_ADC_DELTA_10 register instead.
Make the driver aware of this difference and use the correct bandgap
register depending on the SoC.
This has worked fine on Meson8 and Meson8b because the bootloader is
already initializing the bandgap setting.
Fixes: 6c76ed31cd05 ("iio: adc: meson-saradc: add Meson8b SoC compatibility")

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
