From mboxrd@z Thu Jan 1 00:00:00 1970 From: wens@csie.org (Chen-Yu Tsai) Date: Wed, 26 Jul 2017 16:28:31 +0800 Subject: [PATCH v2 8/9] ARM: sun8i: a83t: h8homlet-v2: Enable PMIC part of AXP818 PMIC In-Reply-To: <20170726082832.16789-1-wens@csie.org> References: <20170726082832.16789-1-wens@csie.org> Message-ID: <20170726082832.16789-9-wens@csie.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org 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.
