2016-11-18google/chromeec: Add common infrastructure for boot-mode switchesFurquan Shaikh
Instead of defining the same functions for reading/clearing boot-mode switches from EC in every mainboard, add a common infrastructure to enable common functions for handling boot-mode switches if GOOGLE_CHROMEEC is being used. Only boards that were not moved to this new infrastructure are those that do not use GOOGLE_CHROMEEC or which rely on some mainboard specific mechanism for reading boot-mode switches. BUG=None BRANCH=None TEST=abuild compiles all boards successfully with and without ChromeOS option.

2016-10-07google/gru: drive WLAN_MODULE_RST# low as early as possibleBrian Norris
GPIO1_B3 (WLAN_MODULE_RST#) defaults as a pull-up input, but it is also "pulled up" by 1.8V_WLAN. However, 1.8V_WLAN remains low for some time during early boot. This leaves the signal floating somewhere in the middle. This has two potential issues: (1) we're leaking some power for some (hopefully) short period of time (2) we are possibly screwing with the Wifi power sequence; we aren't supposed to deassert PDn (i.e., MODULE_RST#) until all the rails have fully ramped for some period of time Neither of the above issues are likely to be significant, but it is nice to fix, I expect.

2016-08-11rockchip/rk3399: Add code to neuter Type-C PHY for firmware USBJulius Werner
The Rockchip RK3399 integrates a USB Type-C PHY in charge of things like SuperSpeed line muxing for rotated cable orientations in the SoC. While fancy, this is very complicated and we don't want to implement support for the whole thing in firmware. The USB Type-C standard has intentionally been designed in a way that the USB 2.0 (HighSpeed) lines always "just work" in any orientation (by just shorting different pins in the connector together) so that simple use cases like ours can get basic USB functionality without much hassle. However, a semi-configured Type-C PHY can confuse USB 3.0 capable devices into thinking we're actually supporting SuperSpeed, and fail at that rather than establishing a reliable HighSpeed connection. This patch sets enough bits in the Type-C PHY to electrically isolate the SuperSpeed lines from the connector so that the connected device isn't going to get any fancy ideas and reliably falls back to USB 2.0. Also clean up the rest of the USB code while we're at it: avoid writing a few bits that are already in the right state from their reset values anyway, or reading values whose content we already know for this SoC. Rename the USB controllers to the name actually used in the Rockchip documentation (USB OTGx) rather than the name blindly copied from Exynos code (USB DRDx).
