Subject: Re: [PATCH 3/3] soc: rockchip: power-domain: Add power domain support
for rk3576
hi,
This submission is also required for the pd of rk3576.
commit feb16e5db3c5e6ff7f18bc3c850c3758fad87caa
Author: Finley Xiao <finley.xiao@...k-chips.com>
Date: Tue May 14 17:40:24 2024 +0800
soc: rockchip: power-domain: Add memory reset support for rk3576
This fixes panic when pd power on.
rockchip-pm-domain 27380000.power-management:power-controller:
failed to set domain 'nputop', target_on= 1, val=0
Kernel panic - not syncing: panic_on_set_domain set ...
