From 89682ea1c433f84f004ba4fe852ce56458e593a2 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Mon, 29 Jun 2020 00:04:23 +0300 Subject: ipa: raspberrypi: Pass sensor config back from configure() The Raspberry Pi IPA uses the custom RPI_IPA_ACTION_SET_SENSOR_CONFIG frame action to send the sensor staggered write configuration to the pipeline handler when the IPA is configured. Replace this ad-hoc mechanism by passing the corresponding data back from the IPA to the pipeline handler through the configure() response. This allows synchronous handling of the response on the pipeline handler side.
