-Subject: [PATCH] media: tc358743: fix connected/active CSI-2 lane
- reporting
-
-g_mbus_config was supposed to indicate all supported lane numbers, not
-only the number of those currently in active use. Since the TC358743
-can dynamically reduce the number of active lanes if the required
-bandwidth allows for it, report all lane numbers up to the connected
-number of lanes as supported in pdata mode.
-In device tree mode, do not report lane count and clock mode at all, as
-the receiver driver can determine these from the device tree.
-
-To allow communicating the number of currently active lanes, add a new
-bitfield to the v4l2_mbus_config flags. This is a temporary fix, to be
-used only until a better solution is found.
