From: John Crispin <john@phrozen.org> EN7523 is an armv7 based silicon used inside broadband access type devices such as xPON and xDSL. It shares various silicon blocks with MediaTek silicon such as the MT7622. Signed-off-by: John Crispin <john@phrozen.org> Signed-off-by: Bert Vermeulen <redacted>
It's always nice to see a new SoC family.

Given how closely related this probably is to MT7623/MT7622, should this perhaps just be part of arch/arm/mach-mediatek? According to https://wikidevi.wi-cat.ru/MediaTek#xPON, the older (mips based) MT752x chips are apparently just rebranded to EN752x after the business unit was spun off, but I guess they are still in the same family.

Why is this needed?
