But since there's nothing > about the maker on the product I've left it out of the DT name because > 1) nobody will no that name and 2) keeps the DT filename shorter. based on the cnx-soft article and my own board I would add the following section: ----- There are three variants of this device: - 2GB LPDDR4, 16GB flash, 2.4G WiFi, 100M Ethernet - 4GB LPDDR4, 32GB flash, dual band AC WiFi, Bluetooth 4.x, Gigabit Ethernet - 4GB LPDDR4, 64GB flash, dual band AC WiFi, Bluetooth 4.x, Gigabit Ethernet Presumably the 4GB variants are identical except for the eMMC chip. This patch is tested on the 4GB LPDDR4 32GB eMMC variant. The WiFi / Bluetooth chip is an AP6356S. The Ethernet PHY is a Realtek RTL8211F. ----- While writing this a question came up: should we rename the board if there's a variant using the internal 100M PHY? for example: "meson-g12a-x96-max-gbit" this will allow us to add a "meson-g12a-x96-max-100m" (or any better name) later on > [1] https://www.cnx-software.com/2018/09/25/x96-max-amlogic-s905x2-tv-box/ > > Cc: Martin Blumenstingl <martin.blumenstingl@googlemail.com> > Signed-off-by: Kevin Hilman <khilman@baylibre.com> Tested-by: Martin Blumenstingl <martin.blumenstingl@googlemail.com> (with the Makefile adjustments, see below) > --- > Special thanks to Martin Blumenstingl for extra digging for the manufacturer > > .../boot/dts/amlogic/meson-g12a-x96-max.dts | 28 +++++++++++++++++++ > 1 file changed, 28 insertions(+) it doesn't build the .dtb for me without adding the board to arch/arm64/boot/dts/amlogic/Makefile > create mode 100644 arch/arm64/boot/dts/amlogic/meson-g12a-x96-max.dts > > diff --git a/arch/arm64/boot/dts/amlogic/meson-g12a-x96-max.dts b/arch/arm64/boot/dts/amlogic/meson-g12a-x96-max.dts > new file mode 100644 > index 000000000000..fe94765b671e > --- /dev/null > +++ b/arch/arm64/boot/dts/amlogic/meson-g12a-x96-max.dts > @@ -0,0 +1,28 @@ > +// SPDX-License-Identifier: (GPL-2.0+ OR MIT) > +/* > + * Copyright (c) 2018 Amlogic, Inc.

Hi, On Wed, Jan 9, 2019 at 1:11 AM Da Xue <da@lessconfused.com> wrote: > > I would be careful about adding TV boxes from unknown manufacturers in China. The manufacturer can and will change part numbers willy nilly and cause a ton of confusion. They are assembled with the cheapest part at the time so the DDR, WiFi module, eMMC, and even PCB will change without warning. this is why I sent an update with the actual hardware which was available for testing at the time this patch written / tested. do you have any suggestion how to add support for this device while being prepare for future changes? Regards Martin

Add the G12a (S905X2) based X96 Max board[1]. There is no branding for the manufacturer anywhere on the product, so it took some digging to find the manufacturer. But since there's nothing about the maker on the product I've left it out of the DT name because 1) nobody will no that name and 2) keeps the DT filename shorter.
