This patch adds MIPI CSI/DSIB pad control mux register
from the APB misc block to tegra pinctrl.
Without writing to this register, the dsib pads are
muxed as csi, and cannot be used.
The register is not yet documented in the TRM, here is
the description:
70000820: APB_MISC_GP_MIPI_PAD_CTRL_0
[31:02] RESERVED
[01:01] DSIB_MODE [CSI=0,DSIB=1]
[00:00] RESERVED
These two patches look good to me.
I think we need to take both patches through the Tegra tree, since if
the Tegra DTs start referencing the new pingroup, the driver must
already know about it or it'll error out. So, I hope for an ack from Linus.
Of course, this only applies if you're sending patches to board .dts
files to use the new feature for 3.18; if not, we can apply the pinctrl
driver through the pinctrl tree instead, and wait until 3.19 to use the
new pingroup. I assume you'll want to use the new feature soon though:-)
