[PATCH 0/3] Small changes for Rockchip NVMEM drivers

[Heiko Stuebner]

When the option for legacy cell dt layouts was added, the
Rockchip OTP driver seems to have been overlooked, so set
the necessary option to allow seeing the cells again.

And two patches set the nvmem-type option in the device config.

Heiko Stuebner (3):
  nvmem: rockchip-otp: set add_legacy_fixed_of_cells config option
  nvmem: rockchip-otp: Set type to OTP
  nvmem: rockchip-efuse: set type to OTP

[PATCH 1/3] nvmem: rockchip-otp: set add_legacy_fixed_of_cells config option

[Heiko Stuebner]

From: Heiko Stuebner <heiko.stuebner@cherry.de>

The Rockchip OTP describes its layout via devicetree subnodes,
so set the appropriate property.

[PATCH 2/3] nvmem: rockchip-otp: Set type to OTP

[Heiko Stuebner]

From: Heiko Stuebner <heiko.stuebner@cherry.de>

The Rockchip OTP is obviously an OTP memory, so document this fact.

[PATCH 3/3] nvmem: rockchip-efuse: set type to OTP

[Heiko Stuebner]

From: Heiko Stuebner <heiko.stuebner@cherry.de>

This device currently reports an "Unknown" type in sysfs.
Since it is an eFuse hardware device, set its type to OTP.
