Subject: bus: ti-sysc: Fix handling of forced idle
X-Git-Tag: v5.4-rc1~96^2~14^2~13
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=6ee8241d17c68b94a91efabfd6bdfe63bb1b79c1;p=platform%2Fkernel%2Flinux-rpi.git

bus: ti-sysc: Fix handling of forced idle

For some devices we can get the following warning on boot:

ti-sysc 48485200.target-module: sysc_disable_module: invalid midlemode

Fix this by treating SYSC_IDLE_FORCE like we do for the other bits
for idlemodes mask.
