This series implements a driver for the efuse found on the Amlogic
Meson6/Meson8/Meson8b SoCs.
A new driver is needed because the existing "meson-efuse" driver
communicates through the "secure monitor" firmware with the HW,
while these older SoCs access the hardware registers directly.
An additional patch also explicitly states that the existing
"meson-efuse" driver is only for the Meson GX SoCs by adjusting
the dt-binding docs, Kconfig help texts, etc.
Please note that the dts patch ("ARM: dts: meson: add the efuse node")
is built on top of my other series ("soc: amlogic: Add Meson6/8/8b SoC
Information driver") from: [0]
