I'm working on imx7d,android M6.0.1. now I meet one problem ,can anyone help me ?
By default,the uboot source code about imx7d didnot support the shutdown,so I want to add this feature.
On the mx6sl,it had shutdown funtion:
#define SNVS_LPCR 0x38
static void mx6_snvs_poweroff(void)
void __iomem *mx6_snvs_base = MX6_IO_ADDRESS(MX6Q_SNVS_BASE_ADDR);
value = readl(mx6_snvs_base + SNVS_LPCR);
/* set TOP and DP_EN bit */
writel(value | 0x60, mx6_snvs_base + SNVS_LPCR);
so,I want to write one shutdown funtion follow this method,but I didnot know the register address in imx7d,can anyone tell me how to get the register address in uboot ?
Thanks very much!
1.the uboot version is 2015/04.
