== SRU Justification ==
User reported that Ubuntu will hang at boot on Rockchip boards with
RK818 power management IC (PMIC), it's because the chip ID was wrong.

It should be changed from 0x8181 to 0x8180.

== Fix ==
* 37ef8c2c (mfd: rk808: Fix RK818 ID template) in linux-next

This patch can be cherry-picked into E/F.
For B/D, this patch needs to be backported with some context
adjustment as the entries for RK817/RK809 were not there.

== Test ==
Test kernels can be found here:
https://people.canonical.com/~phlin/kernel/lp-1853192-RK818/

These test kernels were built with ROCKCHIP ARM64 support enabled
(bug 1825222) have been tested by the bug reporter, PaweĊ‚ Jarosz,
and the test results are good.

== Regression Potentail ==
Low, ID change limited to a specific hardware.
