[PATCH v2 0/3] nvmem: mtk-efuse: mt6572 support

This patch series adds MediaTek mt6572 efuse support. Unlike newer SoCs,
its efuse controller doesn't work properly with 8-bit reads, leading to
invalid data with current mtk-efuse driver implementation.

This behavior can be observed with devmem (0x10009174 and 0x10009178 are
thermal calibration cells):
~ # devmem 0x10009174 32
0x00CDD4CD
~ # devmem 0x10009178 32
0x0F76865D

0xCD

0x00
~ # devmem 0x1000917a 8
0x00
~ # devmem 0x1000917b 8
0x00

Patch 1 adds dt-bindings compatible for the mt6572,
Patch 2 adds platform data option to use aligned 32-bit reads instead
of plain readb().
Patch 3 adds platform data for mt6572 SoC.
