Subject: greybus: arche-apb-ctrl: Export operational fns from driver
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=65fd5a5018c8c5b7ddf14dffa75474b3a9040851;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

greybus: arche-apb-ctrl: Export operational fns from driver

In order to use single wake/detect line for both APB's we need to have
access to APB operational functions to parent/SVC driver.
So export coldboot, standby_boot, fw_flashing and poweroff operation
functions from the driver.

Testing Done: Tested on EVT1.2 and DB3.5 platform
