Linux kernel source tree

There is no semantic change, but it is a nicer on the eyes of a reader, because TIM_CCR1 + 4 * ch encodes internal register knowledge, while TIM_CCRx(ch + 1) keeps that information completely in the header defining the registers. While I expected this to not result in any changes in the binary, gcc 13 (as provided by Debian in the gcc-13-arm-linux-gnueabihf 13.2.0-12cross1 package) compiles the new version with an allmodconfig to more compact code: $ source/scripts/bloat-o-meter drivers/pwm/pwm-stm32.o-pre drivers/pwm/pwm-stm32.o add/remove: 0/0 grow/shrink: 0/2 up/down: 0/-488 (-488) Function old new delta stm32_pwm_get_state 968 936 -32 stm32_pwm_apply_locked 1920 1464 -456 Signed-off-by: Uwe Kleine-König <u.kleine-koenig@baylibre.com> Link: https://lore.kernel.org/r/d7ef7a6158df4ba6687233b0e00d37796b069fb3.1718791090.git.u.kleine-koenig@baylibre.com Signed-off-by: Uwe Kleine-König <ukleinek@kernel.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.
