For SoCs like gs101 that need a special regmap, register this with of_syscon_register_regmap api, so it can be returned by syscon_regmap_lookup_by_phandle() and friends. For SoCs that don't require a custom regmap, revert back to syscon creating the mmio regmap rather than duplicating the logic here. exynos_get_pmu_regmap_by_phandle() api is also updated to retrieve the regmap via syscon. The exynos_get_pmu_regmap_by_phandle() api is kept around until fw_devlink support for syscon property is added for the pinctrl-samsung driver that also runs at postcore_initcall level. All other exynos client drivers can revert back to syscon_regmap_lookup_by_phandle().

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.
