tps659112 的供电问题

使用tps659112供电 有两个问题
1 使用恒定1v avs供电 会不会导致系统不稳定，比如引起vpss等死机
2 如何配置avs使能，目前我们修改内核配置 没有看到tps659112的相关选项，就打开了TI TPS40400 PMBus PMIC和GPIO voltage regulator两项，结果如下：
omap_voltage_domain_lookup: Voltage driver init not yet happened.Faulting!
omap_voltage_add_dev: VDD specified does not exist!
OMAP GPIO hardware version 0.1
OMAP GPIO hardware version 0.1
omap_mux_init: Add partition: #1: core, flags: 0
