platform/chrome: Fix i2c-designware adapter name

2015-11-10T03:43:33Z

Commit d80d134182ba ("i2c: designware: Move common probe code into i2c_dw_probe()") caused the I2C adapter lookup code here to fail for PCI enumerated i2c-designware because commit changed the adapter name but didn't update it here. Fix the I2C adapter lookup by using the "Synopsys DesignWare I2C adapter" name.

platform/chrome: Support reading/writing the vboot context

2015-10-07T22:05:53Z

Some EC implementations include a small nvram space used to store verified boot context data. This patch offers a way to expose this data to userspace. Reviewed-by: Javier Martinez Canillas Signed-off-by: Emilio López Signed-off-by: Olof Johansson

platform/chrome: cros_ec: Fix possible leak in led_rgb_store()

2015-10-07T21:34:26Z

Function led_rgb_store() contains some direct returns in error cases that leak the already allocated cros_ec_command message structure. Make sure that 'msg' is freed in all exit paths. Detected by Coverity CID 1309666. Signed-off-by: Christian Engelmayer Signed-off-by: Olof Johansson

platform/chrome: cros_ec: Fix leak in sequence_store()

2015-10-07T21:34:26Z

The allocated cros_ec_command message structure is not freed in function sequence_store(). Make sure that 'msg' is freed in all exit paths. Detected by Coverity CID 1309667. Signed-off-by: Christian Engelmayer Signed-off-by: Olof Johansson

platform/chrome: Enable Chrome platforms on 64-bit ARM

2015-10-07T21:34:26Z

With Chrome running on 64-bit ARM devices, add ARM64 to the list of supported architectures. Signed-off-by: Thierry Reding [olof; Fixed up due to addition of COMPILE_TEST] Signed-off-by: Olof Johansson

platform/chrome: cros_ec_dev - Add a platform device ID table

2015-10-07T21:34:26Z

If the cros_ec_dev driver is built as a module, modalias information is not filled so the module is not autoloaded. Add a platform device table and use the MODULE_DEVICE_TABLE() macro to export that information in the module so user-space can match the modalias uevent and autoload it.

platform/chrome: cros_ec_lpc - Add support for Google Pixel 2

2015-10-07T21:34:26Z

Since the verion of ACPI in Google BIOS does not enumerate the devices in the LPC bus, the cros_ec_lpc driver resorts to DMI data to check if a system is supported by the driver and autoload if built as a module. Add information about the Google Pixel 2 to the DMI device table. Signed-off-by: Javier Martinez Canillas Signed-off-by: Olof Johansson

platform/chrome: cros_ec_lpc - Use existing function to check EC result

2015-10-07T21:34:26Z

Commit 6db07b633658 ("mfd: cros_ec: Check result code from EC messages") added a common cros_ec_check_result() function that can be used to check the ec_msg->result for errors and warns about them. Use the existing function instead of duplicating same check in the driver.

platform/chrome: Make depends on MFD_CROS_EC instead CROS_EC_PROTO

2015-10-07T21:34:26Z

The ChromeOS EC LPC and chardev drivers 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 devices that are matched with these drivers are registered by the ChromeOS EC mfd driver, they really depend on MFD_CROS_EC. And because this config option selects CROS_EC_PROTO, that dependency is met as well. So make the drivers to depend on MFD_CROS_EC instead of CROS_EC_PROTO.

Revert "platform/chrome: Don't make CHROME_PLATFORMS depends on X86 || ARM"

2015-10-07T21:34:25Z

This reverts commit d12bbcd3ea44 ("platform/chrome: Don't make CHROME_PLATFORMS depends on X86 || ARM") since it was found to not be the correct fix for the MFD_CROS_EC config unmet direct dependencies warning. The correct solution was to add the needed dependencies to the MFD_CROS_EC symbol. Besides the revert, this patch extends the CHROME_PLATFORMS symbol dependencies and adds || COMPILE_TEST to allow drivers to have build coverage on other architectures.
