[PATCH v2 0/2] nvmem: rockchip-efuse: add write support with VQPS gating

[Hrushiraj Gandhi <hrushirajg23@gmail.com>]

Add RK3399 eFuse write (OTP programming) support, gated on the presence
of an optional VQPS programming supply in the device tree.

Changes in v2:
  - Replaced the rockchip,efuse-write-enable boolean property (v1) with
    a proper optional vqps-supply regulator, as suggested by Heiko
    Stuebner. The supply presence acts as the hardware-level gate for
    write support; the driver owns regulator sequencing entirely inside
    the write callback (enable before A_PGM strobe loop, disable after).
  - Removed stale debug dev_info() left from development.
  - Fixed checkpatch: removed blank line after while open-brace in
    rockchip_rk3399_efuse_read().
