The Netronix board E60K02 can be found some several Ebook-Readers, at least the Kobo Clara HD and the Tolino Shine 3. The board is equipped with different SoCs requiring different pinmuxes.
For now the following peripherals are included: - LED - Power Key - Cover (gpio via hall sensor) - RC5T619 PMIC (the kernel misses support for rtc and charger subdevices). - Backlight via lm3630a - Wifi sdio chip detection (mmc-powerseq and stuff) It is based on vendor kernel but heavily reworked due to many changed bindings. Signed-off-by: Andreas Kemnade <andr...@kemnade.info> --- Changes in v3: - better led name - correct memory size - comments about missing devices Changes in v2: - reordered, was 1/3 - moved pinmuxes to their actual users, not the parents of them - removed some already-disabled stuff - minor cleanups backligt dependencies: module autoloading: https://patchwork.kernel.org/patch/11139987/ enable-gpios property (accepted and acked): https://patchwork.kernel.org/patch/11143795/ arch/arm/boot/dts/e60k02.dtsi | 337 ++++++++++++++++++++++++++++++++++ 1 file changed, 337 insertions(+) create mode 100644 arch/arm/boot/dts/e60k02.dtsi diff --git a/arch/arm/boot/dts/e60k02.dtsi b/arch/arm/boot/dts/e60k02.dtsi new file mode 100644 index 0000000000000..84c0447b9a1bd --- /dev/null +++ b/arch/arm/boot/dts/e60k02.dtsi @@ -0,0 +1,337 @@ +// SPDX-License-Identifier: GPL-2.0 +/* + * Copyright 2019 Andreas Kemnade + * based on works + * Copyright 2016 Freescale Semiconductor, Inc. + * and + * Copyright (C) 2014 Ricoh Electronic Devices Co., Ltd + * + * Netronix E60K02 board common. + * This board is equipped with different SoCs and + * found in ebook-readers like the Kobo Clara HD (with i.MX6SLL) and + * the Tolino Shine 3 (with i.MX6SL) + */ +#include <dt-bindings/input/input.h> + +/ { + + chosen { + stdout-path = &uart1;
