The ChromeOS EC tunnel I2C bus driver depend on CROS_EC_PROTO but
MFD_CROS_EC select CROS_EC_PROTO instead. Mixing select and depends
on is bad practice as it may lead to circular Kconfig dependencies.
Since the platform device that is matched with the I2C bus driver
is registered by the ChromeOS
Hello,
This patch series attemp to fix the issues that exist with the ChromeOS
EC drivers Kconfig symbols. These are:
1) The MFD_CROS_EC config symbol select CROS_EC_PROTO and CHROME_PLATFORMS
which caused a Kconfig unmet direct dependencies warning.
2) Mix of select and depends on for the

unserviced interrupts from previous transfers that might be
handled in the context of the new transfer.

Implement bus recovery methods for i2c-imx so we can recover from

Once i2c bus SCL/SDA are stuck low during transfer, config the i2c
