platform/chrome: Kconfig: Remove the transitional MFD_CROS_EC config

2020-09-04T07:30:04+00:00

The MFD_CROS_EC config was a transitional Kconfig option to not break current defconfigs in the kernel. Now, this is not required anymore because all the defconfigs have been removed this option and migrated to enable the CrOS EC parts individually.

platform/chrome: cros_ec_typec: Add a dependency on USB_ROLE_SWITCH

2020-06-30T13:46:39+00:00

As reported by the kernel test robot the cros_ec_typec driver fails to build if the USB_ROLE_SWITCH is not selected, to fix that, add a dependency on that symbol. This fixes the following build error: drivers/platform/chrome/cros_ec_typec.c:133: undefined reference to `usb_role_switch_put' ld: drivers/platform/chrome/cros_ec_typec.o: in function `cros_typec_get_switch_handles': drivers/platform/chrome/cros_ec_typec.c:108: undefined reference to `fwnode_usb_role_switch_get' ld: drivers/platform/chrome/cros_ec_typec.c:117: undefined reference to `usb_role_switch_put' Fixes: 7e7def15fa4b ("platform/chrome: cros_ec_typec: Add USB mux control") Reported-by: kernel test robot Acked-by: Prashant Malani Signed-off-by: Enric Balletbo i Serra

treewide: replace '---help---' in Kconfig files with 'help'

2020-06-13T16:57:21+00:00

Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over '---help---'"), the number of '---help---' has been gradually decreasing, but there are still more than 2400 instances. This commit finishes the conversion. While I touched the lines, I also fixed the indentation. There are a variety of indentation styles found. a) 4 spaces + '---help---' b) 7 spaces + '---help---' c) 8 spaces + '---help---' d) 1 space + 1 tab + '---help---' e) 1 tab + '---help---' (correct indentation) f) 1 tab + 1 space + '---help---' g) 1 tab + 2 spaces + '---help---' In order to convert all of them to 1 tab + 'help', I ran the following commend: $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/' Signed-off-by: Masahiro Yamada

platform/chrome: Add Type C connector class driver

2020-03-22T10:11:26+00:00

Add a driver to implement the Type C connector class for Chrome OS devices with ECs (Embedded Controllers). The driver relies on firmware device specifications for various port attributes. On ACPI platforms, this is specified using the logical device with HID GOOG0014. On DT platforms, this is specified using the DT node with compatible string "google,cros-ec-typec". The driver reads the device FW node and uses the port attributes to register the typec ports with the Type C connector class framework, but doesn't do much else. Subsequent patches will add more functionality to the driver, including obtaining current port information (polarity, vconn role, current power role etc.) after querying the EC.

platform: chrome: Add cros-usbpd-notify driver

2020-02-10T18:14:19+00:00

ChromiumOS uses ACPI device with HID "GOOG0003" for power delivery related events. The existing cros-usbpd-charger driver relies on these events without ever actually receiving them on ACPI platforms. This is because in the ChromeOS kernel trees, the GOOG0003 device is owned by an ACPI driver that offers firmware updates to USB-C chargers. Introduce a new platform driver under cros-ec, the ChromeOS embedded controller, that handles these PD events and dispatches them appropriately over a notifier chain to all drivers that use them. On platforms that don't have the ACPI device defined, the driver gets instantiated for ECs which support the EC_FEATURE_USB_PD feature bit, and the notification events will get delivered using the MKBP event handling mechanism.
