From 719ee15464a4f91d4440cd085b2deb399c528703 Mon Sep 17 00:00:00 2001 From: Fenglin Wu Date: Mon, 30 Mar 2020 15:14:14 +0800 Subject: [PATCH] bindings: input: qcom-hv-haptics: Add qcom,fifo-empty-threshold Add optional property "qcom,fifo-empty-threshold" to specify the FIFO empty threshold. The module would generate fifo-empty interrupt when the number of samples in the FIFO is less than this threshold.
