Subject: [PATCH 00/10] add support for VBUS max current and min voltage limits AXP20X and AXP22X PMICs
Date: Fri, 25 Nov 2016 10:09:11 +0100 [thread overview]
Message-ID: <20161125090921.23138-1-quentin.schulz@free-electrons.com> (raw)
The X-Powers AXP209 and AXP20X PMICs are able to set a limit for the VBUS power
supply for both max current and min voltage supplied. This series of patch adds
the possibility to set these limits from sysfs.
Also, the AXP223 PMIC shares most of its behaviour with the AXP221 but the
former can set the VBUS power supply max current to 100mA, unlike the latter.
The AXP223 VBUS power supply driver used to probe on the AXP221 compatible. This
series of patch introduces a new compatible for the AXP223 to be able to set the
current max limit to 100mA.
With that new compatible, boards having the AXP223 see their DT updated to use
the VBUS power supply driver with the correct compatible.
This series of patch also migrates from of_device_is_compatible function to the
data field of of_device_id to identify the compatible used to probe. This
improves the code readability.
