[PATCH] ARM: dts: add core2 padconf region for am3517

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 




According to the technical reference manual for AM35xx system
controller module (SCM) PADCONFS core registers are divided in two
regions: 0x48002030..0x48002268 and 0x480025d8..0x480025FC.
First region is the same for all omap3 SoC and is described in omap3.dtsi.
The second region is the same as in omap34xx (see omap34xx.dtsi)
and omap35xx. The patch adds missing description for the second region.
This patch was tested on AM3517.

Commit 3d495383648a ("ARM: dts: Split omap3 pinmux core device") notes that
Nishanth Menon <nm@xxxxxx> said that 3517 does not have padconf2 region.
Unfortunately I couldn't find reference to his post on mailing list.
This patch was tested on AM3517 SoC and original vendor code contains
pinmuxing for this second region as well.
