Subject: [PATCH v3 0/2] Enable VBUS current boost on pm8150b platforms
Date: Tue, 27 Apr 2021 14:07:10 +0100 [thread overview]
Message-ID: <email@example.com> (raw)
- Drop the SoC regulator constraints for
These will be applied on a per-board basis - Mark Brown
The first version of this patch set the current limit to 3 amps as was done
in downstream. Mark indicated a preference to set this on a per-system
basis instead of blitzing it, as in downstream.
Looking at what was upstream versus what was in my working tree I saw that
in fact the VBUS boost driver had been upstreamed minus accompanying DTS in
So there's no need for a fixes as this driver doesn't appear to be in use.
A subsequent patchset will enable the VBUS boost for the two relevant
First thing though, is the driver + dts change.
- Use regulator_set_current_limit_regmap/regulator_get_current_limit_regmap
with a relevant current-to-bitmap lookup.
- Add a parallel DTS entry to the pm8150b
It looks like this was submitted upstream but not followed up on
I've add regulator-min-microamp/regulator-max-microamp to Wesley's
I've made sure to test that its possible to set the current to anything in
the range of 500 mA to 3 A and confirmed the output on a scope.
Once these two patches are in, I'll send out board enablement for the
sm8150-mtp and qrb5165-rb5.
