Subject: ARM: sun8i: a83t: h8homlet-v2: Enable PMIC part of AXP818 PMIC
X-Git-Tag: v4.14-rc1~66^2~12^2~5
X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=29067930e74d3fb3e3cffaa999642eb526dd4d4e;p=linux.git

ARM: sun8i: a83t: h8homlet-v2: Enable PMIC part of AXP818 PMIC

The AXP813/AXP818 PMICs used with the A83T/H8 SoCs are actually 2 dies
in one package sharing the serial bus (I2C/RSB) pins. One die is the
actual PMIC. The other is an AC100 codec / RTC combo chip.

This patch enables the RSB controller and adds a device node for the
PMIC die to the h8homlet-v2 device tree. Since the AXP813 and AXP818
are virtually identical, this patch uses the compatible string for
the former as a fallback.
