Fallos en registros de gpiochip MIPS32 BRCM63XX bcm6368
« en: 02-11-2018, 23:11 (Viernes) »
El problema lo estoy viendo en el observa telecom vh4032n, que falla la cuenta del gpiochip , parece que empieza a contar en el GPIO480 y tendría que ser el 474, esto parece que viene del kernel, lo estoy viendo a partir del 4.9 en adelante (comprobado el último trunck => fallando)
Pregunto además, si alguien sabe que puedo tocar en el entorno de compilación para intentar corregir esto al menos de manera local? [Pinta chungo] (el dts de la placa está bien)

Comparativa de arranque con kernel 4.4 "no falla" y kernel 4.9 " si falla.

Hola Ficht!

Antes de nada, gracias por informar del error. Resulta que el problema viene del GPIO hog, que se usa para sacar el hub USB fuera del reset. Después de haber adoptado el nuevo driver del pinctrl para brcm63xx aparecieron diversos problemas en varios routers. Pues parece que al vh4032n le tocó éste.
Para solucionarlo hace algún tiempo envié un workaround básico para no usar el GPIO hog porque la solución no parecía simple. A Jonas Gorski como me temía no le gustó la solución, pero trabajó en ello.

Finalmente Jonas ha arreglado el problema.  Los proximos firmwares snapshot deberían tener esto arreglado, y con suerte más adelante también las versiones 18.06 . Este es el commit.
