This mxs usbphy is only needs to be on after system boots up, and software never needs to control it anymore. Meanwhile, usbphy's parent needs to be notified if usb is suspend or not. So we design below mxs usbphy usage: - usbphy1_gate and usbphy2_gate: Their parents are dummy clock, we only needs to enable it after system boots up. - usbphy1 and usbphy2 Usage reserved bit for this clock, in that case, the refcount will be updated, but without hardware changing.

* Clock bindings for Freescale i.MX6 Quad
|
|
|
|
Required properties:
|
|
- compatible: Should be "fsl,imx6q-ccm"
|
|
- reg: Address and length of the register set
|
|
- interrupts: Should contain CCM interrupt
|
|
- #clock-cells: Should be <1>
|
|
|
|
The clock consumer should specify the desired clock by having the clock
|
|
ID in its "clocks" phandle cell. The following is a full list of i.MX6Q
|
|
clocks and IDs.
