[PATCH v4 0/6] rockchip,otp: Support for RK3528, RK3562 and RK3568

[Heiko Stuebner]

This is a continuation of Kever's from april 2025 [0] - hence the v4
The original patches seem to have fallen through the cracks.

Additionally this directly inclues the interal word-size patch [1],
that was previously listed as an external dependency.

And finally meanwhile patches for the RK3528 SoC from Jonas have appeared,
so I've included those too, to get the support for all not-yet supported
SoCs done


Changes in v4:
- rebase onto 6.18-rc8 - the rockchip-otp driver did no receive
  additional comments in the meantime
- include the dependency patch about word-sizes
- add support for RK3528

Changes in v3:
- update the clock name from "usr" to "otp" and re-order to sync with
 other soc.
- rebase on rk3576 and rk3528, changes suggest by Jonas
- Use rk3568 data structure for rk3562

Changes in v2:
- Update the commit message and add maxItems in schema.

[PATCH v4 3/6] nvmem: rockchip-otp: Handle internal word_size in main reg_read op

[Heiko Stuebner]

From: Jonas Karlman <jonas@kwiboo.se>

Rockchip SoCs RK3576 and RK3588 read data from the OTP using 32-bit
words instead of normal 8-bit bytes. Similar RK3506, RK3528, RK3562 and
RK3568 will read data from OTP using 16-bit words.

The nvmem core stride and word_size cannot fully be used as cells is not
always aligned. Continue to report a stride=1 and word_size=1 in
nvmem_config and instead handle use of SoC specific word_size internally
in the driver.

Move current SoC specific word_size handling from the RK3588 read_reg
operation to the main read_reg operation to help simplify the SoC
specific read_reg operation and allow code reuse in a future RK3568
reg_read operation.

This time I'm making sure to respond to the right patch :-)

I applied your series on top of latest master and booted it on my
E20C (rk3528-based). It provides me with entries in which I can
read values, like when I applied Jonas' patch on 6.17, so I guess
that it's OK:

  # for i in /sys/devices/platform/soc/*/rockchip-otp0/cells/*; do echo ${i##*/}:;hexdump $i;done
  cpu-code@2,0:
  0000000 2835
