Subject: [PATCH v4 09/11] arm: dts: mt7622: add sata- and asm_sel nodes
Date: Thu, 20 Aug 2020 12:58:24 +0200 [thread overview]
Message-ID: <20200820105826.6229-10-linux@fw-web.de> (raw)
In-Reply-To: <20200820105826.6229-1-linux@fw-web.de>
From: Frank Wunderlich <frank-w@public-files.de>
asm_sel is for switching between sata and pcie mode
on r64 there is GPIO90 connected to ASM1480 which
switches RX/TX pairs to PCIe/SATA connector
output-low means sata-controller is active
