In order to be able to read raw registers (eg the nv mac address) in wilc1000 during probe before the firmware is loaded and running, we need to run the basic sdio functions initialization, but then we also need to properly deinitialize those right after, to preserve the current driver behavior (keeping the chip idle/unconfigured until the corresponding interface is brought up). Calling wilc_sdio_deinit in its current form is not enough because it merely resets an internal flag. Implement a deinit sequence which symmetrically reset all steps performed in wilc_sdio_init (only for parts activating/deactivating features, for the sake of simplicity, let's ignore blocks size configuration reset) Signed-off-by: Alexis Lothoré <alexis.lothore@bootlin.com> Signed-off-by: Kalle Valo <kvalo@kernel.org> Link: https://msgid.link/20240514-mac_addr_at_probe-v2-5-afef09f1cd10@bootlin.com
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.
