Subject: [PATCH v5 0/4] add coupled regulators for Exynos5422/5800
Date: Wed, 7 Aug 2019 15:38:34 +0200 [thread overview]
Message-ID: <20190807133838.14678-1-k.konieczny@partner.samsung.com> (raw)

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 DTS coupled regulators patch depends on previous patches.
Changes:
v5:
- squashed last patch "remove exynos_bus_passive_target()" into second
- added Acked-by to patch "correct clock enable sequence"
v4:
- removed "opp: core: add regulators enable and disable" from patchset
as it was applied by Viresh Kumar and changed cover letter
- fix patch "devfreq: exynos-bus: correct clock enable sequence" to
correct order of enable/disable
- removed unrelated changes in "devfreq: exynos-bus: convert to use
dev_pm_opp_set_rate()"
- added new patch "devfreq: exynos-bus: remove exynos_bus_passive_target()"
as suggested by Chanwoo Choi
v3:
- added new exynos-bus patch to correct clock and regulator enabling
and disabling sequence as suggested by Chanwoo Choi
- corrected error path in enable and improved commit message in opp/core
- improve comment in devfreq/exynos-bus.c before devfreq_recommended_opp()
- change cover letter as there is new patch
- added note before Signed-off-by in 4th patch
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
