kconfig: Clean up header comments and make them consistent Use this short header style in all Kconfig files: # <description> # <copyright> # <license> ... Also change all <description>s from # Kconfig[.extension] - Foo-related options to just # Foo-related options It's clear enough that it's about Kconfig. The <description> cleanup was done with this command, along with some manual cleanup (big letter at the start, etc.) git ls-files '*Kconfig*' | \ xargs sed -i -E '1 s/#\s*Kconfig[\w.-]*\s*-\s*/# /' Signed-off-by: Ulf Magnusson <Ulf.Magnusson@nordicsemi.no>

license: Replace Apache boilerplate with SPDX tag Replace the existing Apache 2.0 boilerplate header with an SPDX tag throughout the zephyr code tree. This patch was generated via a script run over the master branch. Also updated doc/porting/application.rst that had a dependency on line numbers in a literal include. Manually updated subsys/logging/sys_log.c that had a malformed header in the original file. Also cleanup several cases that already had a SPDX tag and we either got a duplicate or missed updating.

menuconfig SHARED_IRQ
Kconfig: Use a short, consistent style for prompts Consistently use config FOO bool/int/hex/string "Prompt text" instead of config FOO bool/int/hex/string prompt "Prompt text" (...and a bunch of other variations that e.g. swapped the order of the type and the 'prompt', or put other properties between them). The shorthand is fully equivalent to using 'prompt'. It saves lines and avoids tricking people into thinking there is some semantic difference. Most of the grunt work was done by a modified version of https://unix.stackexchange.com/questions/26284/ how-can-i-use-sed-to-replace-a-multi-line-string/26290#26290, but some of the rarer variations had to be converted manually.

bool "Shared interrupt driver"
drivers: intc: Update drivers to use devicetree Kconfig symbol Update intc drivers to use DT_HAS_<compat>_ENABLED Kconfig symbol to expose the driver and enable it by default based on devicetree. We remove 'depend on' Kconfig for symbols that would be implied by the devicetree node existing. Signed-off-by: Kumar Gala <galak@kernel.org>

drivers: add shared interrupt driver This driver allows multiple drivers to share a common interrupt line. This functionality is required on system that conform to the PC interrupt structure. In the context of Zephyr this is needed for SOC's that have their I/O IP blocks behind a PCI interface. Due to the limited number of interrupt lines provided by the PCI interface multiple IP blocks may be configured to share an interrupt line. Drivers that share interrupts must be modified to *not* register their own interrupt service routine as part of their configuration/initialization but instead bind to the correct instance of this driver by name, then register their interrupt service routine with this driver.

help
kconfig: Global whitespace/consistency cleanup Clean up space errors and use a consistent style throughout the Kconfig files. This makes reading the Kconfig files more distraction-free, helps with grepping, and encourages the same style getting copied around everywhere (meaning another pass hopefully won't be needed). Go for the most common style: - Indent properties with a single tab, including for choices. Properties on choices work exactly the same syntactically as properties on symbols, so not sure how the no-indentation thing happened. - Indent help texts with a tab followed by two spaces - Put a space between 'config' and the symbol name, not a tab. This also helps when grepping for definitions. - Do '# A comment' instead of '#A comment' I tweaked Kconfiglib a bit to find most of the stuff. Some help texts were reflowed to 79 columns with 'gq' in Vim as well, though not all, because I was afraid I'd accidentally mess up formatting.

Include shared interrupt support in system. Shared interrupt
support is NOT required in most systems. If in doubt answer no.

refactor common driver initialization priorities Most of the SoC and board Kconfig use the same values for driver initialization priorities. So refactor them, and discard duplicate ones. The shared IRQ init priority was changed so that the kernel default init and device init priorities can be standardized across all SoC/boards. Same goes for DesignWare SPI driver. This also changes the UART_CONSOLE_PRIORITY and IPM_CONSOLE_PRIORITY to UART_CONSOLE_INIT_PRIORITY and IPM_CONSOLE_INIT_PRIORITY, to standardize across all drivers. Note that this does not take away the ability to override those values. This just provides reasonable defaults such that there is virtually no need to override.

Shared IRQ are initialized on POST_KERNEL init level. They
have to be initialized before any device that uses them.
