Subject: [PATCH] ARM: dts: exynos: Remove 'opp-shared' from Exynos4412 bus OPP-tables
Date: Fri, 11 Sep 2020 14:22:36 +0200 [thread overview]
Message-ID: <20200911122236.16805-1-m.szyprowski@samsung.com> (raw)
In-Reply-To: CGME20200911122246eucas1p1a8ccc7c5b970ce6aa9aa346d78ad69df@eucas1p1.samsung.com
Commits 1019fe2c7280 ("ARM: dts: exynos: Adjust bus related OPPs to the
values correct for Exynos5422 Odroids") and 9ff416cf45a0 ("ARM: dts:
exynos: Disable frequency scaling for FSYS bus on Odroid XU3 family")
revealed that 'opp-shared' property for the Exynos bus OPPs was used
incorrectly, what had the side-effect of disabling frequency scaling for
the second and latter buses sharing given OPP-table.
Fix this by removing bogus 'opp-shared' properties from Exynos4412 bus
OPP-tables. This restores frequency scaling for the following busses:
C2C, RightBus, and MFC.
