Subject: [PATCH] arm64: dts: exynos: increase bus frequency for MHL chip
Date: Fri, 01 Dec 2017 12:33:51 +0100	[thread overview]
Message-ID: <20171201113351.16361-1-a.hajda@samsung.com> (raw)

sii8620 supports 1MHz clock, it allows faster transmissions and according
to extensive tests allows to mitigate some obscure bugs in I2C client
logic of the chip.
