nvmem: add Rockchip OTP driver

2019-11-05T17:35:33Z

Newer Rockchip socs like the px30 use a different one-time-programmable memory controller for things like cpu-id and leakage information, so add the necessary driver for it.

nvmem: imx-ocotp: reset error status on probe

2019-11-05T17:35:30Z

If software running before the OCOTP driver is loaded left the controller with the error status pending, the driver will never be able to complete the read timing setup. Reset the error status on probe to make sure the controller is in usable state.

nvmem: imx: scu: support write

2019-11-05T17:35:29Z

The fuse programming from non-secure world is blocked, so we could only use Arm Trusted Firmware SIP call to let ATF program fuse. Because there is ECC region that could only be programmed once, so add a heler in_ecc to check the ecc region.

nvmem: imx: scu: support hole region check

2019-11-05T17:35:29Z

Introduce HOLE/ECC_REGION flag and in_hole helper to ease the check of hole region. The ECC_REGION is also introduced here which is preparing for programming support. ECC_REGION could only be programmed once, so need take care.

nvmem: sc27xx: Change to use devm_hwspin_lock_request_specific() to request one hwlock

2019-11-05T17:35:28Z

Change to use devm_hwspin_lock_request_specific() to help to simplify the cleanup code for drivers requesting one hwlock. Thus we can remove the redundant sc27xx_efuse_remove() and platform_set_drvdata().
