Subject: [PATCH V2] ARM: shmobile: stout: enable R-Car Gen2 regulator quirk
Date: Thu, 15 Feb 2018 11:02:08 +0100	[thread overview]
Message-ID: <20180215100208.24646-1-marek.vasut+renesas@gmail.com> (raw)

Regulator setup is suboptimal on H2 Stout too. The Stout newly has
two DA9210 regulators, so the quirk is extended to handle another
DA9210 at i2c address 0x70.
