Finally had some time to spend on this.
As I've reported to Bartosz, this version does not work on Ecovec out
of the box, as the GPIO line connected to the backlight needs to be
configured to work in output mode before registering the backlight
device.
With this simple change:
$ git diff
diff --git a/arch/sh/boards/mach-ecovec24/setup.c b/arch/sh/boards/mach-ecovec24/setup.c
index dd427bac5cde..eec6e805c3ed 100644
--- a/arch/sh/boards/mach-ecovec24/setup.c
+++ b/arch/sh/boards/mach-ecovec24/setup.c

+ gpio_direction_output(GPIO_PTR1, 1);
gpiod_add_lookup_table(&gpio_backlight_lookup);
gpio_backlight_device = platform_device_register_full(
&gpio_backlight_device_info);
I can now control the gpio through the backlight interface.
So please add this bit on top of next iteration and add my:
