From: ZhengShunQian <zhengsq at rock-chips.com>
Base on nvmem framework, this series patches
implement the eFuse driver of Rockchip SoC.
The data from eFuse contains CPU leakage, chip code and version etc.
The flow of reading data from eFuse is quite simple,
configure the CTRL register, write data address to CTRL
register, then data is available in DOUT register.
The changes versus V0:
1. Enable/disable clock when required.
2. Split the drivers patch into three patches.
3. Update the docs of eFuse.
clk: rockchip: rk3288: Add the clock id of eFuse
nvmem: fix the out-of-range leak in read/write()
nvmem: rockchip-efuse: implement efuse driver
Documentation: rockchip-efuse: describe the usage of eFuse
ARM: dts: rockchip: add eFuse config of rk3288 SoC
