Re: [PATCH 0/5] Add ChromeOS Embedded Controller support
Hi Samuel, On Wed, Dec 12, 2012 at 1:33 PM, Simon Glass s...@chromium.org wrote: (get_maintainer.pl has produced an enormous list - I hope you are all interested.) The ChromeOS Embedded Controller (EC) is an Open Source EC implementation used on ARM and Intel Chromebooks. Current implementations use a Cortex-M3 connected on a bus (such as I2C, SPI, LPC) to the AP. A separate interrupt line is used to indicate when the EC needs service. Functions performed by the EC vary by platform, but typically include battery charging, keyboard scanning and power sequencing. This series includes support for the EC message protocol, and implements a matrix keyboard handler for Linux using the protocol. The EC performs key scanning and passes scan data in response to AP requests. This is used on the Samsung ARM Chromebook. No driver is available for LPC at present. This series can in principle operate on any hardware, but for it to actually work on the Samsung ARM Chromebook, it needs patches which are currently in progress to mainline: Exynos FDT interrupt support and I2C bus arbitration. The driver is device-tree-enabled and a suitable binding is included in this series. Example device tree nodes are included in the examples, but no device tree patch for exynos5250-snow is provided at this stage, since we must wait for the above-mentioned patches to land to avoid errors from dtc.
