* [PATCH 0/2] ARM: OMAP2+: AM4372: Add emif hwmod and dt node

This series adds an hwmod for the emif on am4372. Also, we add a dt node
in order to provide the reg address for the hwmod in order to have
SYSCONFIG access.

Without the hwmod, once PM code is added for am437x, the emif_clkdm sees
no users and may be idled even though we obviously still need it.

Regards,
Dave

Without a hwmod for am43xx emif use counting for emif clockdomain does
not happen correctly so it may be shut off by pm code unintentionally.
