Subject: [PATCH 0/3] bus: fsl-mc: minor updates

From: Ioana Ciornei <[email protected]>

This patch set adds a fix on the userspace support of the fsl-mc bus.
Other than that, a missing device type is added and some other commands
to the list of the accepted ones.

Dan Carpenter (1):
bus: fsl-mc: Fix test for end of loop

Ioana Ciornei (2):
bus: fsl-mc: add the dpdbg device type
bus: fsl-mc: list more commands as accepted through the ioctl

Subject: [PATCH 1/3] bus: fsl-mc: Fix test for end of loop

From: Dan Carpenter <[email protected]>

The "desc" pointer can't possibly be NULL here. If we can't find the
correct "desc" then tt points to the last element of the
fsl_mc_accepted_cmds[] array. Fix this by testing if
"i == FSL_MC_NUM_ACCEPTED_CMDS" instead.

Add some new MC firmware commands that can be received through the
userspace ioctl interface - *get_max_frame_length and *_get_counter.
