From 55aad53fb3f6c7c3c37e296a3bfdd96ca93f6a1f Mon Sep 17 00:00:00 2001 From: Bin Liu Date: Thu, 24 Aug 2017 11:38:35 -0500 Subject: [PATCH] usb: musb: fix endpoint fifo allocation for 4KB fifo memory The fifo memory allocation in mode_2_cfg[] doesn't utilize all the 4KB memory. Increse some endpoint fifo buffers to fully use all the 4KB memory. Now we can support more webcam usecases on DA8xx.
