Subject: [PATCH 0/7] Add cros_ec changes for newer boards
Date: Thu, 17 Apr 2014 10:59:23 -0700 [thread overview]
Message-ID: <1397757570-19750-1-git-send-email-dianders@chromium.org> (raw)
This series adds the most critical cros_ec changes for newer boards
using cros_ec. Specifically:
* Fixes timing/locking issues with the previously upstreamed (but
never used upstream) cros_ec_spi driver.
* Updates the cros_ec header file to the latest version which allows
us to use newer EC features like i2c tunneling.
* Adds an i2c tunnel driver to allow communication to the EC's i2c
devices.
This _doesn't_ get the EC driver fully up to speed with what's in the
current Chromium OS trees. There are a whole slew of cleanup patches
there, an addition of an LPC transport mode, and exports of functions
to userspace. Once these patches land and we have functionality we
can continue to pick more cleanup patches.
Bill Richardson (1):
mfd: cros_ec: Sync to the latest cros_ec_commands.h from EC sources
David Hendricks (1):
mfd: cros_ec: spi: calculate delay between transfers correctly
Doug Anderson (5):
mfd: cros_ec: spi: Add mutex to cros_ec_spi
mfd: cros_ec: spi: Make the cros_ec_spi timeout more reliable
mfd: cros_ec: spi: Increase cros_ec_spi deadline from 5ms to 100ms
i2c: ChromeOS EC tunnel driver
ARM: tegra: Add the EC i2c tunnel to tegra124-venice2
