Subject: [PATCH v5 2/2] arm64: dts: ti: k3-j721e: Update the power domain cells
Date: Mon, 29 Jul 2019 18:00:23 +0530	[thread overview]
Message-ID: <20190729123023.32702-3-lokeshvutla@ti.com> (raw)
In-Reply-To: <20190729123023.32702-1-lokeshvutla@ti.com>

Update the power-domain cells to 2 and mark all devices as
exclusive. Main uart 0 is the debug console for processor boards
and it is used by different software entities like u-boot, atf,
linux simultaneously. So just mark main_uart0 as shared device
for common processor board.
