Some usb drivers rely on external power switches/regulators for the port vbus, and some of these drivers are still using a plain gpio to control the enable and over current indicator pins. To make these drivers more generic, we can use a regulator to handle vbus, and send and over current event, but we are missing a way to transmit the over current pin status, which the usb layer may poll at any time. These patches extend the fixed regulator driver to handle an optional over current gpio pin. Changes v3 -> 3.1 * added Acked-by for DT bindings Changes v2 -> v3 * dropped merged patch to add new API * rebased on top of regulator-next Changes v1->v2 * add new API to get error status instead of extending events (Mark) * use gpiod for fixed regulator: This spears us extra platform data and bindings Axel Haslam (2): regulator: fixed: dt: Allow an optional over current pin regulator: fixed: Handle optional overcurrent pin .../bindings/regulator/fixed-regulator.txt | 2 + drivers/regulator/fixed.c | 59 ++++++++++++++++++++++ 2 files changed, 61 insertions(+) -- 2.9.3 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
