imx: syscounter: make sure asm is volatile

Without the volatile attribute, compilers are entitled to optimize out
the same asm().  In the case of __udelay() in syscounter.c, it calls
`get_ticks()` twice, one for the starting time and the second in the
loop to check the current time.  When compilers inline `get_ticks()`
they see the same `mrrc` instructions and optimize out the second one.
This leads to infinite loop since we don't get updated value from the
system counter.

Here is a portion of the disassembly of __udelay:

  88: 428b       cmp r3, r1
  8a: f8ce 20a4  str.w r2, [lr, #164] ; 0xa4
  8e: bf08       it eq
  90: 4282       cmpeq r2, r0
  92: f8ce 30a0  str.w r3, [lr, #160] ; 0xa0
  96: d3f7       bcc.n 88 <__udelay+0x88>
  98: e8bd 8cf0  ldmia.w sp!, {r4, r5, r6, r7, sl, fp, pc}

Note that final jump / loop at 96 to 88, we don't have any `mrrc`.

With a volatile attribute, the above changes to this:

  8a: ec53 2f0e  mrrc 15, 0, r2, r3, cr14
  8e: 42ab       cmp r3, r5
  90: f8c1 20a4  str.w r2, [r1, #164] ; 0xa4
  94: bf08       it eq
  96: 42a2       cmpeq r2, r4
  98: f8c1 30a0  str.w r3, [r1, #160] ; 0xa0
  9c: d3f5       bcc.n 8a <__udelay+0x8a>
  9e: e8bd 8cf0  ldmia.w sp!, {r4, r5, r6, r7, sl, fp, pc}
  a2: bf00       nop

I'm advised[1] to put volatile on all asm(), so this commit also adds it
to the asm() in timer_init().

imximage: Remove failure when no IVT offset is found

Sometimes imximage throws the following error:

  CFGS    board/freescale/vf610twr/imximage.cfg.cfgtmp
  CFGS    board/freescale/vf610twr/imximage.cfg.cfgtmp
  MKIMAGE u-boot-dtb.imx
Error: No BOOT_FROM tag in board/freescale/vf610twr/imximage.cfg.cfgtmp
arch/arm/mach-imx/Makefile:100: recipe for target 'u-boot-dtb.imx' failed

Later on, when running mkimage for the u-boot.imx it will succeed in
finding the IVT offset.

Looks like some race condition happening during parallel build when
processing mkimage for u-boot-dtb.imx and u-boot.imx.

A proper fix still needs to be implemented, but as a workaround let's
remove the error when the IVT offset is not found.

It is useful to have such message, especially during bring-up phase,
but the build error that it causes is severe, so better avoid the
build error for now.

The error checking can be re-implemented later when we have a proper
fix.

gpio: pca953x_gpio: Support label setting from DT

The PCA953x driver uses "gpio@%x_" as the GPIO bank name, where "%x" is
instantiated with the I2C address of the chip. While this works, it
becomes very confusing if a board has multiple PCAs with the same
address on different I2C busses, and it also becomes an issue when a
GPIO's value is to be set via the 'gpio' command, because this command
only ever sets the value of the first device it encounters, leaving the
other devices inaccessible to the command.

As to not break boards that rely on this naming scheme, we introduce a
new device tree string property "label" for the driver. If it exists, it
is used to build a bank name of the form "%s@%x_" (where %x is still
instantiated with the I2C address). If it does not exist, the legacy
labeling scheme is used.

net: phy: marvell 88e151x: Fix handling of bare RGMII interface type

Commit 68e6ecadc551 ("net: phy: marvell 88e151x: Fix handling of RGMII
interface types") fixed the initialization of 88e151x phys, but made it
so that interfaces of type PHY_INTERFACE_MODE_RGMII had both RX and TX
delay bits cleared. The default (like in m88e1111s_config) is to have
both bits set.

Hence, this patch changes the behavior in the PHY_INTERFACE_MODE_RGMII
case so that both bits are set.

rockchip: clk: rk3399: handle set_rate/get_rate for PLL_PPLL

The device-tree node for the PMU clk controller assigns to its parent
(i.e. PLL_PPLL) even though this clock currently is set up statically
by an init-function.

In order to avoid unexpected failures, a simple implementation of
set_rate (which accepts requests, but notifies the caller of the
preset frequency in its return value) and get_rate (which always
returns the preset frequency) are added.

Note that this is required for the RK808 PMIC to probe successfully on
the RK3399-Q7, following the support for the assigned-clocks property.

This migrates rk_vop (the shared functions used by multiple VOP
mini-drivers) to be compatible with a live tree.

Unfortunately, there's
(i)  a lot of tree traversal needed for a VOP (as each active VOP
     vnode references back to the endpoints in the encoders and vice
     versa) to configure the connection between VOPs and encoders;
(ii) the DTS binding is not too sane and one needs to walk a node's
     parents (the original code just assumed that the device would
     live 3 levels above the property linked through a phandle) until
     a UCLASS_DISPLAY device can be found.

As part of the migration, the code for finding the enclosing display
device has been changed to not assume a specific depth of nesting
(i.e. we walk until we reach the root or find a matching device) and
to use the newly introduced (in the same series) ofnode_get_parent()
function.
