Subject[PATCH v2 00/29] ARM: Realtek DHC SoC info
Date
Hello,

This series adds a soc bus driver for Realtek Digital Home Center SoC families.

v2 is rebased on syscon and RTD1319, adjusts field widths and incorporates
data additions from Stanley's monolithic patch.

The previous RFC's reg hack is superseded in v2 with a trivial read-only
eFuse driver, along with an extension of the nvmem consumer API.

Reminder: For RTD1293 I had to invent my own detection logic, possibly flawed.
Nor have the names of the magic register bits been disclosed.

We have no RTD1294 nor RTD1392 DT in mainline, so their detection is included
mainly as proof of concept. No EVB names were visible in public BSP sources;
Ligomedia seems the only vendor so far with publicly announced RTD1392 STBs,
for RTD1294 I only find one all-Chinese page and some Russian forum posts -
patches and testing welcome. Otherwise we can only test that the other models
are not misdetected as RTD1392 or RTD1294.

DHC upstreaming progress is being tracked at:
https://en.opensuse.org/HCL:Realtek_DHC

Latest experimental patches at:
https://github.com/afaerber/linux/commits/rtd1295-next

Have a lot of fun!

Cheers,
Andreas

v1 -> v2:
* Cleaned up binding schema (Rob)
* Rebased onto syscon mfd refactoring of containing SB2, Iso, etc.
* Limit chip id and rev to 16 bits, as per old header files
* Include mentioned RTD1395, RTD1619 and RTD1319 patches
* Incorporate RTD1392 and RTD1319 bits from Stanley's API export patch
* Add eFuse nvmem driver and adopt and extend nvmem cell API
