Kernel for Galaxy S24, rebased on CLO sources (WIP)
f12a616e0c
Provide a module parameter to request internal loop by the SPI master
controller.
This should make loop testing easier without extra HW modification.
For test automation a logic analyzer is recommended for host
controller-independent verification.
An example test rig configuration and procedure:
i.MX6S RIoRBoard Logic Analyzer
-----------------------------------------
(J13 4) GND ------------- GND
(J13 6) CSPI3-CLK ------> PIN 3
(J13 8) CSPI3-MOSI <----- PIN 2
^ - internal loop configured by SPI_LOOP
| or can be user external jamper.
(J13 10) CSPI3-MISO -----> PIN 1
grab some data and decode it:
sigrok-cli -d fx2lafw --time 160000 --config samplerate=10m \
--channels 0-2 -o dump.sr
sigrok-cli -i dump.sr -P spi:mosi=1:clk=2 > result_for_regression_tests

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
