Subject: [PATCH 6/7] arm64: allwinner: h6: add R_I2C controller
Date: Fri,  4 May 2018 02:38:46 +0800	[thread overview]
Message-ID: <20180503183847.11046-7-icenowy@aosc.io> (raw)
In-Reply-To: <20180503183847.11046-1-icenowy@aosc.io>

Allwinner H6 SoC has a R_I2C controller wired to the PL0/PL1 pins, which
are used in the reference design to connect AXP805 PMIC.

Add support for it.
