Subject: ARM: dts: exynos: Remove 'opp-shared' from Exynos4412 bus OPP-tables
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=a23beead41a18c3be3ca409cb52f35bc02e601b9;p=linux.git

ARM: dts: exynos: Remove 'opp-shared' from Exynos4412 bus OPP-tables

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 buses:
C2C, RightBus, and MFC.
