The Micro Crystal RV8263 has the same IC as the pcf85063 but has an on board crystal. This means that the CAP_SEL bit has to be cleared so the correct capacitance is selected for the crystal. Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>
As stated in a comment pcf85063a and pcf85063tp don't have the same number of registers. Especially, pcf85063tp doesn't have alarm support. Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>

The Epson rx8571 is compatible with the Epson rx8581 RTC. The difference between the rx8571 and rx8581 RTC is that the former has 16 bytes more RAM. This renders them incompatible from a DT point of view. Signed-off-by: Biju Das <biju.das@bp.renesas.com> Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>

Add a driver for the MicroCrystal RV-3028. It is a SMT Real-Time Clock Module that incorporates an integrated CMOS circuit together with an XTAL. It has an i2c interface. The driver handles date/time, alarms, trickle charging, timestamping, frequency offset correction, EEPROM and NVRAM. Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>
Since this documents multiple chips controlled by the isl1208 driver, name it isil,isl1208.txt, as the convention is to use the base driver name in the bindings document for drivers with multiple devices. Include all chips supported by this driver in the docs. Make it clear which properties apply to which chips. Expand documentation for existing isil,evienb property to explain operation in more detail. Existing docs just describe it in terms of setting a bit in a register.

The 32-bit Amlogic Meson SoCs (Meson6, Meson8, Meson8b and Meson8m2) have a built-in RTC block. It has the following inputs: - an 32.768kHz crystal oscillator - an interrupt line - a reset line - 0.9V voltage input Signed-off-by: Ben Dooks <ben.dooks@codethink.co.uk> [resurrected patches from Ben after 2 years] Signed-off-by: Martin Blumenstingl <martin.blumenstingl@googlemail.com> Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>
Add compatible string for Microcrystal RV1805 RTC, which is compatible with AB1805. The RV1805 uses smaller 10 pin package, while the AB1805 uses larger 16pin package, however the die inside the chip is the same.
