Make the default USB device authorization mode configurable at build
time. This is useful for systems that require a mode that is stricter
than the standard setting, as it avoids relying on the kernel command
line being properly set.

Since the wireless USB implementation has been removed and since the
behavior with authorized_default values -1 and 1 is now effectively
same, change the initial value to latter in order to stop using the
leftover value. The former value can still be passed as a module
parameter to retain backwards compatibility.

Add support for ac5 to the EHCI Orion platform driver.
The ac5 SOC has DDR starting at offset 0x2_0000_0000,
Hence it requires a larger than 32-bit DMA mask to operate.
Move the dma mask to be pointed by the OF match data, and
use that match data when initializng the DMA mask.

With the Cypress CCGx Type-C controller the following error is
sometimes observed on boot:
[ 16.087147] ucsi_ccg 1-0008: failed to reset PPM!
[ 16.087319] ucsi_ccg 1-0008: PPM init failed (-110)
When the above timeout occurs the following happens:
1. The function ucsi_reset_ppm() is called to reset UCSI controller.
This function performs an async write to start reset and then
polls for completion.
2. An interrupt occurs when the reset completes. In the interrupt
handler, the OPM field in the INTR_REG is cleared and this clears
the CCI data in the PPM. Hence, the reset completion status is
cleared.
3. The function ucsi_reset_ppm() continues to poll for the reset
completion, but has missed the reset completion event and
eventually timeouts.
In this patch, we store CCI when handling the interrupt and make
reading after async write gets the correct value.
To align with the CCGx UCSI interface guide, this patch updates the
driver to copy CCI and MESSAGE_IN before they are reset when UCSI
interrupt acknowledged.
When a new command is sent, the driver will clear the old CCI to avoid
ucsi_ccg_read() getting wrong CCI after ucsi_ccg_async_write() when
the UCSI interrupt is not handled.
Finally, acking the UCSI_READ_INT interrupt before calling complete()
in ISR to ensure that the ucsi_ccg_sync_write() would wait for the
interrupt handling to complete.

Use of_reset_control_array_get_optional_exclusive() instead, it is
implemented as:
static inline struct reset_control *
of_reset_control_array_get_optional_exclusive(struct device_node *node)
{
return of_reset_control_array_get(node, false, true, true);
}
This makes the code easier to understand and removes the last remaining
direct use of of_reset_control_array_get(). No functional changes.
This change was made possible by commit f4cc91ddd856 ("usb: dwc3:
of-simple: remove Amlogic GXL and AXG compatibles"), which made the
parameters passed to of_reset_control_array_get() constant.

In sddr55_{read|write}_data(), the address variables are needlessly typed
as *unsigned long* -- which is 32-bit type on the 32-bit arches and 64-bit
type on the 64-bit arches; those variables' value should fit into just 3
command bytes and consists of 10-bit block # (or at least the max block #
seems to be 1023) and 4-/5-bit page # within a block, so 32-bit *unsigned*
*int* type should be more than enough...

bcachefs btree nodes are big - typically 256k - and btree roots are
pinned in memory. As we're now up to 18 btrees, we now have significant
memory overhead in mostly empty btree roots.
And in the future we're going to start enforcing that certain btree node
boundaries exist, to solve lock contention issues - analagous to XFS's
AGIs.
Thus, we need to start allocating smaller btree node buffers when we
can. This patch changes code that refers to the filesystem constant
c->opts.btree_node_size to refer to the btree node buffer size -
btree_buf_bytes() - where appropriate.

When issuing discards, we may need to flush the journal if there's too
