Subject: [PATCH 00/11] net: dsa: ksz9477: use regmap to add I2C support next to SPI
Date: Wed, 11 Jan 2023 09:01:08 +0100 [thread overview]
Message-ID: <20230111080119.933475-1-a.fatoum@pengutronix.de> (raw)
The Linux DSA driver supports both I2C and SPI as management interface
by using regmaps as abstraction. barebox regmaps were not quite that
powerful yet, so we rework our regmaps to support optional formatting
and then use that to make the KSZ driver work with either I2C or SPI
transports.
This series has been tested with both an I2C-connected KSZ8563 and
a SPI-connected KSZ9563, both of which are supported by the barebox
KSZ9477 driver.
Ahmad Fatoum (11):
regmap: consolidate reg/val format into regmap_format
regmap: support formatted read and write
regmap: port regmap_init_spi
regmap: factor out regmap cdev size calculation
net: dsa: ksz9477: switch to regmap_init_spi
net: dsa: ksz9477: create regmap cdev for switch registers
drivers: base: regmap: introduce REGMAP_I2C
dev: add dev_bus_is_spi/i2c helpers
net: dsa: ksz9477: refactor to prepare i2c support
regmap: i2c: use formatted I/O
net: ksz9477: add I2C support
