Zoltan HERPAI 99545b4bb1 d1: add new target
This target adds support for the Allwinner D1 RISC-V based SoCs.

 - RISC-V single-core T-Head C906 (RV64GCV)
 - Tensilica HiFi4 DSP
 - DDR2/DDR3 support
 - 10/100/1000M ethernet
 - usual peripherals like USB2, SPI, I2C, PWM, etc.

Four boards are supported:
 - Dongshan Nezha STU
    - 512Mb RAM
    - ethernet

 - LicheePi RV Dock
    - 512Mb RAM
    - wireless-only (RTL8723DS)

 - MangoPi MQ-Pro
    - 512Mb RAM
    - there are pads available for an SPI flash
    - wireless-only (RTL8723DS)

 - Nezha D1
    - 512Mb/1Gb/2Gb RAM
    - 256Mb NAND flash
    - ethernet, wireless

Installation:
Standard SD-card installation via dd-ing the generated image to
an SD-card of at least 256Mb.

Subject: [PATCH 019/117] dt-bindings: nvmem: Allow bit offsets greater than a
byte
Some NVMEM devices contain cells which do not start at a multiple of the
device's stride. However, the "reg" property of a cell must be aligned
to its provider device's stride.
These cells can be represented in the DT using the "bits" property if
that property allows offsets up to the full stride. 63 is chosen
assuming that NVMEM devices will not have strides larger than 8 bytes.
