Create driver to support the soft reset (i.e. peripheral)
of all Rockchip SoCs.
Example of usage:
i2c driver:
ret = reset_get_by_name(dev, "i2c", &reset_ctl);
if (ret) {
error("reset_get_by_name() failed: %d\n", ret);
}
reset_assert(&reset_ctl);
udelay(50);
reset_deassert(&reset_ctl);
i2c dts node:
resets = <&cru SRST_P_I2C1>, <&cru SRST_I2C1>;
reset-names = "p_i2c", "i2c";

|

help
|
|
Enable support for the reset controller driver class. Many hardware
|
|
modules are equipped with a reset signal, typically driven by some
|
|
reset controller hardware module within the chip. In U-Boot, reset
|
|
controller drivers allow control over these reset signals. In some
|
|
cases this API is applicable to chips outside the CPU as well,
|
|
although driving such reset isgnals using GPIOs may be more
|
|
appropriate in this case.

doing anything beyond a little error checking.
