From 216814fb0167673c6417b5db83ade84e58031e2c Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Thu, 10 Oct 2013 09:06:27 -0300 Subject: [PATCH] [media] v4l: omap4iss: csi2: Replace manual if statement with a subclk field Instead of manually checking whether the CSI2 module is CSI2a or CSI2b in order to select the right subclock to enable/disable, add a subclk field to the iss_csi2 structure, initialize it with the corresponding subclock value and use it at runtime.
