Subject: [PATCH asahi-soc/dt] arm64: dts: apple: t7000: Add missing CPU p-state 7 for J96 and J97
Date: Mon, 17 Feb 2025 14:10:05 +0800 [thread overview]
Message-ID: <20250217-mini4-cpufreq-v1-1-8974e90dd806@gmail.com> (raw)
Add missing CPU p-state 7 @ 1512 MHz for iPad mini 4.
Fixes: e97323994f4a ("arm64: dts: apple: t7000: Add cpufreq nodes")
Signed-off-by: Nick Chan <towinchenmi@gmail.com>

Note, some sources state that Apple TV HD has 1512 MHz A8 too, but that
is incorrect, the maximum frequency on Apple TV HD as configured by iBoot
is 1392 MHz.
