The changes in detail are:
- introduces a data-structure for chip-specific drivers to register
features/callbacks with the common driver: at this time, this is
limited to a callback for setting the pin polarities (between the
VOP and the encoder modules) and a flag to signal 10bit RGB
capability
- refactors the probing of regulators into a helper function that
can take a list of regulator names to probe and autoset
- moves the priv data-structure into a (common) header file to be
used by the chip-specific drivers to provide base addresses to
the common driver
- uses a callback into the chip-specific driver to set pin polarities
(replacing the direct register accesses previously used)
- splits enabling the output (towards an encoder) into a separate

this is a SD/MMC or SPI formatted payload takes place.
The output of dumpsys now prints the image type (spl_hdr), whether it
is a SD/MMC or SPI image, and the (padded) size of the image:
$ ./tools/dumpimage -l ./spl.img

rockchip: board: puma_rk3399: add support for serial# and cpuid# via efuses
With our efuse driver for the RK3399 ready, we can add the
board-specific code that consumes the cpuid from the efuse block and
postprocesses it into the system serial (using the same CRC32 based
derivation as in Linux).
We expose the cpuid via two distinct environment variables:
serial# - the serial number, as derived in Linux
cpuid# - the raw 16 byte CPU id field from the fuse block

rockchip: efuse: add (misc) driver for RK3399 non-secure efuse block
This adds a simple driver for reading the efuse block of the RK3399.
It should be easy enough to add drivers for other devices (e.g. the
RK3328, RK3368, etc.) by passing the device details via driver_data.
Unlike the kernel driver (using the nvmem subsystem), we don't expose
the efuse as multiple named cells, but rather as a linear memory that
can be read using misc_read(...).
The primary use case (as of today) is the generation of a 'serial#'
(and a 'cpuid#') environment variable for the RK3399-Q7 (Puma)
system-on-module.
Note that this adds a debug-only (i.e. only if DEBUG is defined)
command 'rk3399_dump_efuses' that dumps the efuse block's content.
N.B.: The name 'rk3399_dump_efuses' was intentionally chosen to
include a SoC-name (together with a comment in the function) to
remind whoever adds support for additional SoCs that this
function currently makes assumptions regarding the size of the
fuse-box based on the RK3399. The hope is that the function is
adjusted to reflect any changes resulting from generalising the
driver for multiple SoCs and is then renamed.
