9fea3696ef rockchip: otp: fix misc_read() return values
The documentation for misc_read() says:

    Return: number of bytes read if OK (may be 0 if EOF), -ve on error

The Rockchip efuse driver implements this so it should return the number
of bytes read rather than zero on success.  Fix this so that the driver
follows the usual contract for read operations.

8fa1870e11 rockchip: otp: Refactor to use driver data and ops
Refactor the driver to use driver data and ops to simplify handling
of SoCs that require a unique read op.

Use readl_poll_sleep_timeout instead of a custom poll loop, and add
validation of input parameter to main read op.

8a8d24bdf1 dm: treewide: Rename ..._platdata variables to just ..._plat
Try to maintain some consistency between these variables by using _plat as
a suffix for them.

d1998a9fde dm: treewide: Rename ofdata_to_platdata() to of_to_plat()
This name is far too long. Rename it to remove the 'data' bits. This makes
it consistent with the platdata->plat rename.

caa4daa2ae dm: treewide: Rename 'platdata' variables to just 'plat'
We use 'priv' for private data but often use 'platdata' for platform data.
We can't really use 'pdata' since that is ambiguous (it could mean private
or platform data).

Rename some of the latter variables to end with 'plat' for consistency.

41575d8e4c dm: treewide: Rename auto_alloc_size members to be shorter
This construct is quite long-winded. In earlier days it made some sense
since auto-allocation was a strange concept. But with driver model now
used pretty universally, we can shorten this to 'auto'. This reduces
verbosity and makes it easier to read.

Coincidentally it also ensures that every declaration is on one line,
thus making dtoc's job easier.

a907dc3f25 misc: add driver for the Rockchip otp controller
Newer Rockchip socs like the px30 use a different ip block to handle
one-time-programmable memory, so add a misc driver for it as well.
