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. Changes in v2: - Update tunnel binding as per swarren - Removed i2c20 alias for i2c tunnel 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 .../devicetree/bindings/i2c/i2c-cros-ec-tunnel.txt | 39 + arch/arm/boot/dts/tegra124-venice2.dts | 26 + drivers/i2c/busses/Kconfig | 9 + drivers/i2c/busses/Makefile | 1 + drivers/i2c/busses/i2c-cros-ec-tunnel.c | 304 ++++++ drivers/mfd/cros_ec.c | 7 +- drivers/mfd/cros_ec_spi.c | 67 +- include/linux/mfd/cros_ec.h | 4 +- include/linux/mfd/cros_ec_commands.h | 1128 ++++++++++++++++++-- 9 files changed, 1493 insertions(+), 92 deletions(-) create mode 100644 Documentation/devicetree/bindings/i2c/i2c-cros-ec-tunnel.txt create mode 100644 drivers/i2c/busses/i2c-cros-ec-tunnel.c -- 1.9.1.423.g4596e3a -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
