Subject: [PATCH 0/5] i2c: ls2x: Add support for the Loongson-2K/LS7A I2C
Date: Thu, 22 Sep 2022 19:39:53 +0800 [thread overview]
Message-ID: <cover.1663835855.git.zhoubinbin@loongson.cn> (raw)
Hi all:
This patch series adds support for the I2C module found on various
Loongson systems with the Loongson-2K SoC or the Loongson LS7A bridge chip.
For now, the I2C driver is suitable for DT-based or ACPI-based systems.
BTW:
I have only tested on the Loongson-3A5000+LS7A1000/LS7A2000 under LoongArch
architecture.
Thanks.
Binbin Zhou (5):
i2c: core: Pick i2c bus number from ACPI if present
i2c: gpio: Add support on ACPI-based system
dt-bindings: i2c: add bindings for Loongson LS2X I2C
i2c: Add driver for Loongson-2K/LS7A I2C controller
LoongArch: Enable LS2X I2C in loongson3_defconfig
