From 49b94d580abc47ef96b2adef0ef3ac0582f2c0c1 Mon Sep 17 00:00:00 2001 From: Andrey Konovalov Date: Tue, 26 Jan 2021 08:49:34 +0100 Subject: media: i2c: imx219: Implement V4L2_CID_LINK_FREQ control This control is needed for imx219 driver, as the link frequency is independent from the pixel rate in this case, and can't be calculated from the pixel rate.
