Merge tag 'chrome-platform-4.4' of git://git.kernel.org/pub/scm/linux/kernel/git/olof/chrome-platform
Pull chrome platform updates from Olof Johansson: "Here's the branch of chrome platform changes for v4.4. Some have been queued up for the full 4.3 release cycle since I forgot to send them in for that round (rebased early on to deal with fixes conflicts). Most of these enable EC communication stuff -- Pixel 2015 support, enabling building for ARM64 platforms, and a few fixes for memory leaks. There's also a patch in here to allow reading/writing the verified boot context, which depends on a sysfs patch acked by Greg" * tag 'chrome-platform-4.4' of git://git.kernel.org/pub/scm/linux/kernel/git/olof/chrome-platform: platform/chrome: Fix i2c-designware adapter name platform/chrome: Support reading/writing the vboot context sysfs: Support is_visible() on binary attributes platform/chrome: cros_ec: Fix possible leak in led_rgb_store() platform/chrome: cros_ec: Fix leak in sequence_store() platform/chrome: Enable Chrome platforms on 64-bit ARM platform/chrome: cros_ec_dev - Add a platform device ID table platform/chrome: cros_ec_lpc - Add support for Google Pixel 2 platform/chrome: cros_ec_lpc - Use existing function to check EC result platform/chrome: Make depends on MFD_CROS_EC instead CROS_EC_PROTO Revert "platform/chrome: Don't make CHROME_PLATFORMS depends on X86 || ARM"
