[PATCH 0/4] RFC: firmware: meson-sm: add chipid sysfs export

[Viacheslav Bocharov]

The Amlogic Meson SoC Secure Monitor implements a call to retrieve an
unique SoC ID starting from the GX Family and all new families.
But GX-family chips (e.g. GXB, GXL and newer) supports also 128-bit
chip ID. 128-bit chip ID consists 32-bit SoC version and 96-bit OTP data.

This patchset introduces an exported sysfs string for the 128-bit chipid,
considering a check for the version of the returned value. If the chip
does not support version 2 of the call, it falls back to (where possible)
information from the meson-gx-socinfo driver to supplement the data from OTP.

Viacheslav Bocharov (4):
  firmware: meson-sm: change sprintf to scnprintf
  firmware: meson_sm: Add chipid number sysfs entry
  soc: amlogic: meson-gx-socinfo: export socinfo for use in other
    modules
  firmware: meson_sm: use meson_gx_socinfo for compatibility
