* reset: simple: export reset_simple_ops to be referred from modulesKunihiko Hayashi2018-07-161-0/+1
| | | | | | | | | Allow reset_simple_ops to be referred from modules that use reset-simple framework by adding EXPORT_SYMBOL_GPL.

* reset: simple: Enable for ASPEED systemsJoel Stanley2018-02-201-0/+2
| | | | | | | | | | | ASPEED BMC SoCs have a reset controller in the LPC IP that can be controlled using this driver to release the UARTs from reset. No special configuration is required, so only the compatible string is added. Signed-off-by: Joel Stanley <joel@jms.id.au> Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de>

| | | | | | | | Add reset line status readback, inverted status support, and socfpga device tree quirks to the simple reset driver, and use it to replace the socfpga driver. Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de>
* reset: add reset-simple to unify socfpga, stm32, sunxi, and zx2967Philipp Zabel2017-10-171-0/+134
Copy reusable parts from the sunxi driver, to add a driver for simple reset controllers with reset lines that can be controlled by toggling bits in exclusive, contiguous register ranges using read-modify-write cycles under a spinlock. The following patches will replace compatible reset drivers with reset-simple, extending it where necessary.
