] [Rtc drive adapter
(1) modify the kernel configuration file, rtc compiled module (rtc-hym8563) driving
the Z: \ Workspace \ XBHV811 \ the Customer \ toolchains \ Board \ XMH811B \ hi3751v810_arm64_android_defconfig
# CONFIG_RTC_DRV_HYM8563 IS SET Not changed: CONFIG_RTC_DRV_HYM8563 = m
(2) adding i2c bus driver
Z: \ workSpace \ XBHV811 \ device \ hisilicon \ bigfish \ sdk \ source \ msp \ drv \ i2cbus
and modified Z: \ workSpace \ XBHV811 \ device \ hisilicon \ bigfish \ sdk \ source \ msp \ drv \ Makefile: objects + = i2cbus
(3) modify dtsi, increasing the device information corresponding platform: Z: \ workSpace \ XBHV811 \ device \ hisilicon \ bigfish \ sdk \ source \ kernel \ linux-4.9.y \ arch \ arm64 \ boot \ dts \ hisilicon \ hi3751v81x.dtsi
