From efc4e1d65b2f08847b7ac961dde18904173b396f Mon Sep 17 00:00:00 2001 From: Samuel Jiang Date: Thu, 25 Apr 2019 14:43:23 +0800 Subject: meta-gsj: quanta-nvme-powerctrl: Update package process Update quanata-nvme-powerctrl process and delete two duplication function and variable init_once.sh: 1. Dump input pin information because of confirming HW signal. 2. HW POWER_U2 default is output high. If detect SSD is plugged, don't need to initialize POWER_U2 again. 3. Add RST_BMC_U2 steps, check PWRGD_U2 is fine, wait 100ms then st RST_BMC_U2 high. nvme_powermanager.sh: 1. Add RST_BMC_U2 steps, check PWRGD_U2 is fine, wait 100ms then set RST_BMC_U2 high. 2. Independent package for power control delete nvme_main DBus property trigger and tranfer led trigger to nvem_main package.
