The Quartz64 Model B has a Winbound 25Q64DWZPIG SPI flash chip, identified as 'U13' on the component placement schematic. In the Quartz 64 Model-B Schematic from 20220124 on page 17, we can see that the VCC connector is connected to VCCIO_FLASH and page 4 shows that that in turn is connected to the VCCIO2 domain. That domain uses vcc_1v8 as its power source. This fixes the following warning: spi-nor spi4.0: supply vcc not found, using dummy regulator Signed-off-by: Diederik de Haas <didi.debian@cknow.org> Link: https://lore.kernel.org/r/20250503152917.138648-3-didi.debian@cknow.org Signed-off-by: Heiko Stuebner <heiko@sntech.de>
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.
