![]() Convert the driver to use regmap to access the chips. Due to the convoluted register mapping scheme, implement read/write/volatile check functions that untangle the mess and perform check accordingly. This patch does not zap the internal register cache of the PCA953x driver, nor does it push the regmap access down into the gpiochip accessors to simplify the review. All that is in subsequent patches.

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 Restructured Text 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.
