Subject: [PATCH] arm64: dts: stratix10: enable i2c, add i2c periperals
Date: Wed, 21 Feb 2018 14:25:41 -0600 [thread overview]
Message-ID: <20180221202541.3258-1-atull@kernel.org> (raw)
Add clock for i2c
Enable i2c1
Set the i2c bus speed to 100KHz
Add the following i2c peripherals
* ds1339 RTC
* 24c32 EEPROM
* max1619 temperature monitor
* ltc2497 ADC
* Add a fixed regulator for the ADC's Vref.
This requires Dinh Nguyen's Stratix10 clock driver
("clk: socfpga: stratix10: add clock driver for Stratix10 platform")
