usb: i.MX: Add i.MX28 support ...

The existing i.MX chipidea support can be used for i.MX28 as well. The
main difference is that the i.MX28 doesn't have a usbmisc unit, so the
bulk of this patch makes this unit optional in the driver.

common.h: move the generic IOMEM definition to asm-generic/io.h ...

arch/mips/include/asm/io.h defines arch-specific IOMEM().

The generic definition of IOMEM() should go to asm-generic/io.h
because it is a collection of fallback defaults when there is no
specific definition in <asm/io.h>.

of: refactor of_read_number for clarity ...

While the code is correct, less sophisticated static analyzers (and
users operating them..) trip over it, because they don't see that
the be32_to_cpu argument is evaluated multiple times only if it's
constant. Moving the side effect out:

- Lets us avoid the false positive
- Aligns us with what Linux does
- Makes the code IMO a bit clearer

Do so.

iopoll: Introduce read_poll_timeout ...

barebox adoption of Linux commit:

| commit 5f5323a
| Author: Dejin Zheng <zhengdejin5@gmail.com>
| Date:   Mon Mar 23 23:05:51 2020 +0800
|
|     iopoll: introduce read_poll_timeout macro
|
|     this macro is an extension of readx_poll_timeout macro. the accessor
|     function op just supports only one parameter in the readx_poll_timeout
|     macro, but this macro can supports multiple variable parameters for
|     it. so functions like phy_read(struct phy_device *phydev, u32 regnum)
|     and phy_read_mmd(struct phy_device *phydev, int devad, u32 regnum) can
|     also use this poll timeout core. and also expand it can sleep some time
|     before read operation.

clk: at91: port Linux v5.6 SAM9X60 (new ARM926EJ-S) clock support ...

During a bug hunt that ultimately turned out unrelated to the state
of the barebox at91 clk driver, I synchronized its state with Linux v5.6.

Bug fixes and clean up to minimize the diff were split out in separate
prior commits.  This last commit imports the rest, which is basically
support for Microchip's new ARM926EJ-S SoC, the SAM9x60.

clk: at91: add sama5d2 audio PLL support ...

Commit 7310b976 ("clk: at91: fix compilation errors in sama5d2.c") and
follow-up commit ca3077068c ("clk: at91: delete dead i2s/audio code")
had deleted the i2s/audio clock related parts of the upstream driver.

This was mostly due to unwillingness on my part to understand the code
enough for porting them and because I deemed them unnecessary to support
in barebox. The former has changed and the latter is not totally true as
audio PLL derived clocks may be muxed as inputs for programmable and
generated clocks.

Port them over and mimize the diff to upstream.

clk: implement clk_register_fixed_rate ...

We lack a way to instantiate a fixed clock while specifying a parent.
This is used in the at91 clock code sync with upstream in a later
commit, so prepare by porting clk_register_fixed_rate.

It's based on the Linux commit of the same name with the difference that
it doesn't use (and thus doesn't require) a struct device_d * as first
parameter.
