Subject: [PATCH 0/4] Add I2C support on TH1520
Date: Thu, 25 Apr 2024 10:21:31 +0200	[thread overview]
Message-ID: <20240425082138.374445-1-thomas.bonnefille@bootlin.com> (raw)

This adds I2C support in the device tree of the T-Head TH1520 RISCV-SoC
and a default configuration for the BeagleV-Ahead. It appears that the
TH1520 I2C is already supported in the upstream kernel through the
Synopsis Designware I2C adapter driver.
As there is no clock driver for this board as of today, this patch
series uses a fixed-clock named i2c_ic_clk.
There is also no pinctrl driver yet so pinmux must be handled manually
for now.
It also fixes the order of the nodes in the device tree to comply with
device-tree coding-style.
