Broadcom Kona platform

Kona was Broadcom's mobile SoC platform. Most notably, Kona chips were used in multiple budget Samsung devices.

The initial work for Kona mainlining was started around 2012, when the board_bcm generic device and some extra drivers were added to the kernel (commit). Proper board development, as well as the addition of board files for the BCM21664 started around 2013, and ended around 2014, with a few commits to some devices later on (see: BCM21664 bringup). Support for the BCM23550 was added around 2016 (see: BCM23550 bringup).

Many Kona platform devices also make use of BCM590XX PMUs; initial support for one of them - the BCM59056 - was added in early 2014. According to a message on the Linux mailing list, support was planned for the similar BCM59054, however it has not been merged into upstream.

In 2014 Broadcom stopped its Mobile SoC activities, which also stopped further developments from Linaro (see this mail on the mailing list).
