a282ada198 IPQ40xx: clk: add USB clock handling
USB clocks were completely forgotten as driver would always return 0 even if clock ID was unknown.

This behaviour changed with "IPQ40xx: clk: dont always return 0" and this will now causes the USB-s to fail probing as clock enable will return -EINVAL.

So to fix that lets add all of the USB clocks to the driver.

Fixes: 430e1dcf ("IPQ40xx: Add USB nodes")

20476b51aa IPQ40xx: clk: dont always return 0
Currently the driver will go through the clock ID-s and set/enable them as needed.
But if the ID is unknown it will fall through the switch case to the default case which will always return 0.

This is not correct and default cases should return a error code since clock ID is unknown.
So lets return -EINVAL instead.

164cc98a7b IPQ40xx: clk: drop breaks in switch case
There is no point in having break statements in the switch case as there is already a return before break.

So lets drop them from the driver.

90534536a3 IPQ40xx: clk: use dev_read_addr()
Lets convert the driver to use dev_read_addr() instead of the devfdt_get_addr().

While we are here, lets also alphabetise the includes.

cfec8d36ce IPQ40xx: Add PRNG support
Since we now have the driver for Qualcomm PRNG HW, lets use it and add the necessary clocks and nodes.

5ae15415c1 IPQ40xx: clk: Use dt-bindings instead of hardcoding
Its common to use dt-bindings instead of hard-coding clocks or resets.
So lets use the imported Linux GCC bindings on IPQ40xx target.

e479a7d52e arm: Add support for Qualcomm IPQ40xx family
This introduces initial support for the popular Qualcomm
IPQ40x8 and IPQ40x9 WiSoC series.

IPQ40xx series have 4x Cortex A7 ARM-v7A cores.
Supported are: IPQ4018, IPQ4019, IPQ4028 and IPQ4029.

IPQ40x8 and IPQ40x9 use the same cores, but differ in
addressable RAM size (1GB for IPQ40x9 and 256MB for IPQ40x8)
and supported peripherals (IPQ40x8 lacks RGMII, LCD controller
and EMMC/SDHCI controllers).

IQP4028/IPQ4029 models differ from IPQ4018/IPQ4019 only
by their rated temperatures rates with IPQ402X models being
rated for wider temperature ranges.

Initially this supports:
* Simple clock driver (Only for UART1 now, will be extended)
* Pinctrl driver (Supports UARTX and GPIO now, will be extended)
* GPIOs already supported by msm_gpio driver with updates
* UARTs already supported by serial_msm driver with updates

Further peripherals will come in later patches.
