Subject: [PATCH v2 0/4] add coupled regulators for Exynos5422/5800
Date: Mon, 15 Jul 2019 14:04:12 +0200 [thread overview]
Message-ID: <20190715120416.3561-1-k.konieczny@partner.samsung.com> (raw)
In-Reply-To: CGME20190715120430eucas1p1dd216e552403899e614845295373e467@eucas1p1.samsung.com
Hi,
The main purpose of this patch series is to add coupled regulators for
Exynos5422/5800 to keep constrain on voltage difference between vdd_arm
and vdd_int to be at most 300mV. In exynos-bus instead of using
regulator_set_voltage_tol() with default voltage tolerance it should be
used regulator_set_voltage_triplet() with volatege range, and this is
already present in opp/core.c code, so it can be reused. While at this,
move setting regulators into opp/core.
This patchset was tested on Odroid XU3.
The last patch depends on two previous.
Changes in v2:
- improve regulators enable/disable code in opp/core as suggested by
Viresh Kumar
- add new patch for remove unused dt-bindings as suggested by Krzysztof
Kozlowski
Regards,
Kamil
