Date: Wed, 24 Jun 2020 18:56:27 +0300 From: Iskren Chernev <iskren.chernev@...il.com> To: Sebastian Reichel <sre@...nel.org>, Rob Herring <robh+dt@...nel.org> Cc: linux-pm@...r.kernel.org, devicetree@...r.kernel.org, linux-kernel@...r.kernel.org, ~postmarketos/upstreaming@...ts.sr.ht, Jonathan Bakker <xc-racer2@...e.ca>, Vladimir Barinov <vladimir.barinov@...entembedded.com>, Iskren Chernev <iskren.chernev@...il.com> Subject: [PATCH v3 0/6] power: supply: max17040 support compatible devices The max17040 fuel gauge is part of a family of 8 chips that have very similar mode of operations and registers. This patch set adds: - compatible strings for all supported devices and handles the minor differences between them; - handling for devices reporting double capacity via maxim,double-soc; - handling for setting rcomp, a compensation value for more accurate reading, affected by battery chemistry and operating temps; - suppot for SOC alerts (capacity changes by +/- 1%), to prevent polling every second; - improved max17040 driver with regmap and devm_ The datasheets of the supported devices are linked [0] [1] [2] [3].
