usb: misc: usb3503: Remove 100ms sleep on reset, conform to data sheet

2013-06-03T18:01:09+00:00

The usb3503 driver sleeps a flat 100ms when resetting the chip, with a
comment about waiting for the reference clock. This seems to be a
board-specific detail that should not hold up boot across all platforms.
This patch reduces the sleep to the 4ms initialization delay that the
chip itself actually requires (as per its data sheet). If certain boards
require more time to set up the reference clock, they should change this
through local patches or add a proper, configurable synchronization
mechanism.

usb: misc: usb3503: Adding device tree entry 'disabled-ports'

2013-05-30T12:32:52+00:00

This patch is to add a property 'disabled-ports' representing the unused port
of USB3503. USB3503 can support up to 3 USB host port and each ports can be
controlled to be enabled or disabled. Do not describe this property if all
ports must be enabled.

You can represent the ports to disable in the device tree.

	usb3503@08{
		...
		disabled-ports = <2 3>;
		...
	};

usb: misc: usb3503: Add to select the ports to disable

2013-05-30T12:32:52+00:00

This patch is to disable the USB ports unconnected to USB3503. In order to
disable the port, 'port_off_mask' must be set.

* Disable PORT1 only
	.port_off_mask = USB3503_OFF_PORT1;

* Disable PORT1 and PORT3 only
	.port_off_mask = USB3503_OFF_PORT1 | USB3503_OFF_PORT3;

* Enables all ports
	.port_off_mask = 0;
