Subject: [PATCH v3 2/7] drivers: thermal: tsens: try load regmap from parent for 8960
Date: Thu, 16 Jul 2020 00:44:57 +0200 [thread overview]
Message-ID: <20200715224503.30462-3-ansuelsmth@gmail.com> (raw)
In-Reply-To: <20200715224503.30462-1-ansuelsmth@gmail.com>
Devices based on 8060 tsens driver (ipq8064) use the reg of the gcc
driver. Try to load the regmap of the parent as they share the same
regs.
