kernel cycle:
Core:
- The pin control Kconfig entry PINCTRL is now turned into
a menuconfig option. This obviously has the implication of
making the subsystem menu visible in menuconfig. This is
happening because of two things:
- Intel have started to deploy and depend on pin controllers
in a way that is affecting users directly. This happens
on the highly integrated laptop chipsets named after
geographical places: baytrail, broxton, cannonlake,
cedarfork, cherryview, denverton, geminilake, lewisburg,
merrifield, sunrisepoint... It started a while back and
now it is ever more evident that this is crucial
infrastructure for x86 laptops and not an embedded
obscurity anymore. Users need to be aware.
- Pin control expanders on I2C and SPI that are
arch-agnostic. Currently Semtech SX150X and Microchip
MCP28x08 but more are expected. Users will have to be
able to configure these in directly for their set-up.
- Just go and select GPIOLIB now that we made sure that
GPIOLIB is a very vanilla subsystem. Do not depend on
it, if we need it, select it.
- Exposing the pin control subsystem in menuconfig uncovered
a bunch of obscure bugs that are now hopefully fixed,
all more or less pertaining to Blackfin.
- Unified namespace for cross-calls between pin control and
GPIO.
- New support for clock skew/delay generic DT bindings
and generic pin config options for this.
- Minor documentation improvements.
Various:
- The Renesas SH-PFC pin controller has evolved a lot. It seems
Renesas are churning out new SoCs by the minute.
- A bunch of non-critical fixes for the Rockchip driver.
- Improve the use of library functions instead of open coding.
- Support the MCP28018 variant in the MCP28x08 driver.
- Static constifying.
