This adds a devicetree for the Tolino Shine 2 HD Ebook reader. It is based on boards marked with "37NB-E60QF0+4A2". It is equipped with an i.MX6SL SoC. Expected to work: - Buttons - Wifi - Touchscreen - LED - uSD - USB - RTC Not working due to missing drivers: - Backlight (requires NTXEC driver) - EPD Not working due to unknown reasons: - deep sleep (echo standby >/sys/power/state works), wakeup fails when imx_gpc_pre_suspend(true) was called. Signed-off-by: Andreas Kemnade <andreas@xxxxxxxxxxxx> --- Reason for RFC: The suspend trouble might be caused by bad devicetree. But as the devicetree is already useful I decided to submit it. arch/arm/boot/dts/Makefile | 1 + arch/arm/boot/dts/imx6sl-tolino-shine2hd.dts | 582 +++++++++++++++++++ 2 files changed, 583 insertions(+) create mode 100644 arch/arm/boot/dts/imx6sl-tolino-shine2hd.dts diff --git a/arch/arm/boot/dts/Makefile b/arch/arm/boot/dts/Makefile index e6a1cac0bfc7..c65fa3852246 100644 --- a/arch/arm/boot/dts/Makefile +++ b/arch/arm/boot/dts/Makefile @@ -581,6 +581,7 @@ dtb-$(CONFIG_SOC_IMX6Q) += \ imx6qp-zii-rdu2.dtb dtb-$(CONFIG_SOC_IMX6SL) += \ imx6sl-evk.dtb \ + imx6sl-tolino-shine2hd.dtb \ imx6sl-tolino-shine3.dtb \ imx6sl-warp.dtb dtb-$(CONFIG_SOC_IMX6SLL) += \ diff --git a/arch/arm/boot/dts/imx6sl-tolino-shine2hd.dts b/arch/arm/boot/dts/imx6sl-tolino-shine2hd.dts new file mode 100644 index 000000000000..7b28e19a1d98 --- /dev/null +++ b/arch/arm/boot/dts/imx6sl-tolino-shine2hd.dts @@ -0,0 +1,582 @@ +// SPDX-License-Identifier: (GPL-2.0) +/* + * Device tree for the Tolino Shine 2 HD ebook reader + * + * Name on mainboard is: 37NB-E60QF0+4A2 + * Serials start with: E60QF2 + * + * Copyright 2020 Andreas Kemnade + */ + +/dts-v1/;
