The ADC IP available on the RZ/G3S differs slightly from the one found on the RZ/G2L. The identified differences are as follows: - different number of channels (one being used for temperature conversion); consequently, various registers differ - different default sampling periods - the RZ/G3S variant lacks the ADVIC register. To accommodate these differences, the rzg2l_adc driver has been updated by introducing the struct rzg2l_adc_hw_params, which encapsulates the hardware-specific differences between the IP variants. A pointer to an object of type struct rzg2l_adc_hw_params is embedded in struct rzg2l_adc_data. Additionally, the completion member of struct rzg2l_adc_data was relocated to avoid potential padding, if any. The code has been adjusted to utilize hardware-specific parameters stored in the new structure instead of relying on plain macros. The check of chan->channel in rzg2l_adc_read_raw() function, against the driver specific mask was removed as the subsystem should have already been done this before reaching the rzg2l_adc_read_raw() function. Along with it the local variable ch was dropped as chan->channel could be used instead.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
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.
