From 71e3a18114ebdb48482d731d04bff7a222036381 Mon Sep 17 00:00:00 2001 From: Tomi Valkeinen Date: Mon, 14 Jun 2021 13:23:44 +0200 Subject: media: ti-vpe: cal: allow more than 1 source pads CAL RX has a single sink and a single source pad. To support multiple streams, we will have multiple source pads (up to 8, one for each CAL context). Change the driver to allow creating more source pads and change the code accordingly to handle multiple source pads. We still keep CAL_CAMERARX_NUM_SOURCE_PADS as 1, and the behavior is unchanged. Also rename CAL_CAMERARX_PAD_SOURCE to CAL_CAMERARX_PAD_FIRST_SOURCE to highlight that it's the first source.
