This patch series introduces a DT binding for chromeos fingerprint devices and then implements support to boot those processors during driver probe if the BIOS hasn't done it already. Changes from v3 (https://lore.kernel.org/r/20220318015451.2869388-1-swboyd@xxxxxxxxxxxx): * Drop spi_device_id because it isn't used * Dropped struct members for gpios * Picked up tags Changes from v2 (https://lore.kernel.org/r/20220317005814.2496302-1-swboyd@xxxxxxxxxxxx): * Dropped cros-ec spi dt properties that aren't of use right now * Picked up tags Changes from v1 (https://lore.kernel.org/r/20220314232214.4183078-1-swboyd@xxxxxxxxxxxx): * Properly do the boot sequence * Add a message that we're booting and delaying a while * Fix typo in commit text * Change binding to not spell out reset-gpios and indicate that boot0 is about asserting boot mode * Split device id to different patch as it's a different topic from booting Stephen Boyd (3): dt-bindings: chrome: Add ChromeOS fingerprint binding platform/chrome: cros_ec_spi: Match cros-ec-fp compatible platform/chrome: cros_ec_spi: Boot fingerprint processor during probe .../bindings/chrome/google,cros-ec-fp.yaml | 66 +++++++++++++++++++ drivers/platform/chrome/cros_ec_spi.c | 43 +++++++++++- 2 files changed, 106 insertions(+), 3 deletions(-) create mode 100644 Documentation/devicetree/bindings/chrome/google,cros-ec-fp.yaml Cc: Rob Herring <robh+dt@xxxxxxxxxx> Cc: <devicetree@xxxxxxxxxxxxxxx> Cc: Guenter Roeck <groeck@xxxxxxxxxxxx> Cc: Douglas Anderson <dianders@xxxxxxxxxxxx> Cc: Craig Hesling <hesling@xxxxxxxxxxxx> Cc: Tom Hughes <tomhughes@xxxxxxxxxxxx> Cc: Alexandru M Stan <amstan@xxxxxxxxxxxx> Cc: Tzung-Bi Shih <tzungbi@xxxxxxxxxx> Cc: Matthias Kaehlcke <mka@xxxxxxxxxxxx> base-commit: ffb217a13a2eaf6d5bd974fc83036a53ca69f1e2 -- https://chromeos.dev
