Subject: [PATCH v1 2/4] mfd: qcom-pm8008: Convert irq chip to config regs
Date:   Thu, 16 Feb 2023 22:22:12 +0000
Message-Id: <20230216222214.138671-3-aidanmacdonald.0x0@gmail.com>
In-Reply-To: <20230216222214.138671-1-aidanmacdonald.0x0@gmail.com>

MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

Replace type and virtual registers, which are both deprecated,
with config registers. This also simplifies the driver because
IRQ types are set in one place, the set_type_config() callback.
