I load linuxbios, and alix1c runs for 3-4 seconds and turns off. I am
convinced it is something in PM hardware, just don't know what.
Here are the settings we make
static void cs5536_setup_power_button(void)
/* Power Button Setup */
outl(0x40020000, PMS_IO_BASE + 0x40);
/* setup WORK_AUX/GPIO24, it is the external signal for 5536
* vsb_work_aux controls all voltage rails except Vstandby & Vmem.
* We need to enable, OUT_AUX1 and OUTPUT_ENABLE in this order.
* If WORK_AUX/GPIO24 is not enabled then soft-off will not work.
outl(GPIOH_24_SET, GPIO_IO_BASE + GPIOH_OUT_AUX1_SELECT);
outl(GPIOH_24_SET, GPIO_IO_BASE + GPIOH_OUTPUT_ENABLE);
