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:-)
I don't have any board .dts patches ready for upstream consumption
quite yet. Feel free to use whichever path to mainline you see fit.
I've actually just sent the Tegra pull requests for 3.18 today. Linus,
if you want to take this whole series (or at least patch 1/2) through
the pinctrl tree, that would be great. The patches will then already be
there when we need them as a basis for any DT patches in the Tegra tree
for 3.19.
Patch 2,
