From mboxrd@z Thu Jan 1 00:00:00 1970 From: Linus Walleij Subject: [PATCH 1/2 v3] input: keyboard: DT bindings for the D-Link DIR-685 touchkeys Date: Tue, 30 May 2017 14:09:17 +0200 Message-ID: <20170530120918.27357-1-linus.walleij@linaro.org> Return-path: Sender: linux-input-owner@vger.kernel.org To: Dmitry Torokhov , linux-input@vger.kernel.org Cc: Linus Walleij , devicetree@vger.kernel.org List-Id: devicetree@vger.kernel.org This adds device tree bindings for the D-Link DIR-685 touchkeys. It's a simple homebrewn touchkey controller (by D-Link referred to as "touchpad") on I2C. Cc: devicetree@vger.kernel.org Acked-by: Rob Herring Signed-off-by: Linus Walleij --- ChangeLog v2->v3: - No changes, just resending. ChangeLog v1->v2: - Rename from "touchpad" to touchkeys" consistently. - Add Rob's ACK. --- .../bindings/input/dlink,dir685-touchkeys.txt | 21 +++++++++++++++++++++ 1 file changed, 21 insertions(+) create mode 100644 Documentation/devicetree/bindings/input/dlink,dir685-touchkeys.txt diff --git a/Documentation/devicetree/bindings/input/dlink,dir685-touchkeys.txt b/Documentation/devicetree/bindings/input/dlink,dir685-touchkeys.txt new file mode 100644 index 000000000000..10dec1c57abf --- /dev/null +++ b/Documentation/devicetree/bindings/input/dlink,dir685-touchkeys.txt @@ -0,0 +1,21 @@ +* D-Link DIR-685 Touchkeys + +This is a I2C one-off touchkey controller based on the Cypress Semiconductor +CY8C214 MCU with some firmware in its internal 8KB flash.
