Description

Other devices could be added if whatever the regulator needed for UHS is enabled.

Read perf def improved on the gnome disk benchmarks.

Jira reference number [AR-9999]

let's enable salva's UHS overlay for RK3399

tested on PBP with 2ghz with 64 gig samsung evo select

i like using the yabs.sh fio benchmark for mixed r/w tests

curl -sL yabs.sh | bash -s -- -i -g -n

also did gnome disk utility read benchmark

before kernel 6.6.10

Cool got some tiny gains on everything but 4k block

after UHS enabled 6.6.10
