The I2C bus will get stuck when reading 0 byte. So we add validation of

This driver is designed in a generic manner, so resets should be

Signed-off-by: NMasahiro Yamada <yamada.masahiro@socionext.com>

My motivation for this patch is to make reset control handling
optional for generic drivers.

I want to add reset control to drivers/usb/host/ehci-generic.c,
but it is used by several platforms, some will implement a reset
controller driver, some will not.

Add no-op stubs in order to avoid link error for drivers that
implement reset controlling, but still it is optional.

Unlike Linux, nothing about errno.h is arch-specific in U-Boot.
As you see, all of arch/${ARCH}/include/asm/errno.h is just a

export headers to user-space, so we just have to care about the
consistency in the U-Boot tree.
