On some Samsung-based SoCs there are separate bus clocks / gates each for each pinctrl instance. To be able to access each pinctrl instance's registers, this bus clock needs to be running, otherwise register access will hang. Google Tensor gs101 is one example for such an implementation. Update the driver to handle this optional bus clock: * handle an optional bus clock from DT * prepare it during driver probe * enclose all relevant register accesses with a clock enable & disable Signed-off-by: André Draszik <andre.draszik@linaro.org> Link: https://lore.kernel.org/r/20240426-samsung-pinctrl-busclock-v3-2-adb8664b8a7e@linaro.org Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org> |

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.
