Subject[PATCH v4 1/4] VFIO: platform: add reset struct and lookup table
Date
This patch introduces the vfio_platform_reset_combo struct that
stores all the information useful to handle the reset modality:
compat string, name of the reset function, name of the module that
implements the reset function. A lookup table of such structures
is added, currently void.

Signed-off-by: Eric Auger <eric.auger@linaro.org>
