From 72802a86e11c34e819fbfb38f58c5aef668f833d Mon Sep 17 00:00:00 2001 From: Eugen Hristev Date: Mon, 13 Dec 2021 14:49:26 +0100 Subject: [PATCH] media: atmel: atmel-isc-base: report frame sizes as full supported range The ISC supports a full broad range of frame sizes. Until now, the subdevice was queried for possible frame sizes and these were reported to the user space. However, the ISC should not care about which frame sizes the subdev supports, as long as this frame size is supported. Thus, report a continuous range from smallest frame size up to the max resolution.
