Linux kernel source tree
283ae0c65e
DSPI registers are NOT continuous, some registers are reserved and
accessing them from userspace will trigger external abort, add regmap
register access table to avoid below abort.
For example on S32G:
# cat /sys/kernel/debug/regmap/401d8000.spi/registers
Internal error: synchronous external abort: 96000210 1 PREEMPT SMP
...
Call trace:
regmap_mmio_read32le+0x24/0x48
regmap_mmio_read+0x48/0x70
_regmap_bus_reg_read+0x38/0x48
_regmap_read+0x68/0x1b0
regmap_read+0x50/0x78

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.
