There is a bug in regards to deferred probing within the drivers core
that causes GPIO-driver to suspend after its users. The bug appears if
GPIO-driver probe is getting deferred, which happens after introducing
dependency on PINCTRL-driver for the GPIO-driver by defining "gpio-ranges"
property in device-tree. The bug in the drivers core is old (more than 4
years now) and is well known, unfortunately there is no easy fix for it.
The good news is that we can workaround the deferred probe issue by
changing GPIO / PINCTRL drivers registration order and hence by moving
PINCTRL driver registration to the arch_init level and GPIO to the
subsys_init.

The msix number for vf is different, depends on the max vf number.
Futherly if the vf supports roce, the offset of msix is not fixed.

[Why]
VGA sometimes has trouble retrieving the EDID on very long cables, KVM
switches, or old displays.
[How]
Only require EDID read for HDMI and DVI and exempt other types (DP,
VGA). We currently don't support VGA but if anyone adds support in the
future this might get overlooked.

[Why]
Some boards seem to have a problem where HPD is high on HDMI even though
no display is connected. We don't want to report these as connected. DP
spec still requires us to report DP displays as connected when HPD is
high but we can't read the EDID in order to go to fail-safe mode.
[How]
If connector_signal is not DP abort detection if we can't retrieve the
EDID.

This patch is first version of Mediatek Command Queue(CMDQ) driver. The
CMDQ is used to help write registers with critical time limitation,
such as updating display configuration during the vblank. It controls
Global Command Engine (GCE) hardware to achieve this requirement.
Currently, CMDQ only supports display related hardwares, but we expect
it can be extended to other hardwares for future requirements.

Use new return type vm_fault_t for fault handler. For
now, this is just documenting that the function returns
a VM_FAULT value rather than an errno. Once all instances
are converted, vm_fault_t will become a distinct type.
Ref- commit 1c8f422059ae ("mm: change return type to vm_fault_t")
Previously vm_insert_mixed() returns err which driver
mapped into VM_FAULT_* type. The new function
vmf_insert_mixed() will replace this inefficiency by
returning VM_FAULT_* type.
vmf_error() is the newly introduce inline function
in 4.17-rc6.

Secure Proxy is another communication scheme in Texas Instrument's
devices intended to provide an unique communication path from various
processors in the System on Chip(SoC) to a central System Controller.
Secure proxy is, in effect, an evolution of current generation Message
Manager hardware block found in K2G devices. However the following
changes have taken place:
Secure Proxy instance exposes "threads" or "proxies" which is
primary representation of "a" communication channel. Each thread is
preconfigured by System controller configuration based on SoC usage
requirements. Secure proxy by itself represents a single "queue" of
communication but allows the proxies to be independently operated.
Each Secure proxy thread can uniquely have their own error and threshold
interrupts allowing for more fine control of IRQ handling.
Provide the driver support for Secure Proxy and thread instances.
NOTE: Secure proxy configuration is only done by System Controller,
hence these are assumed to be pre-configured instances.

In a much bigger system SoCs, the number of Rx channels can be
many and mostly unused based on the system of choice, and not all
Rx channels need IRQs and allocating all memory at probe will be
inefficient. Some SoCs could have total threads in the 100s and usage
would be just 1 Rx thread.
Thus, request and map the IRQs and allocate memory only when needed.
Since these channels are requested by client drivers on need, our
utilization will be optimal.

The OMAP Mailbox driver is directly using an integer value as
match data for distinguishing the interrupt register layout
between OMAP2 and OMAP4+ SoCs. Introduce a dedicated structure
for storing this match data, and simplify the probe function by
using the of_device_get_match_data() function. This allows the

The Realtek RTL8723BS and RTL8723DS chipsets are SDIO wifi chips. They
also contain a Bluetooth module which is connected via UART to the host.
Realtek's userspace initialization tool (rtk_hciattach) differentiates
these two via the HCI version and revision returned by the
HCI_OP_READ_LOCAL_VERSION command.
Additionally we apply these checks only the for UART devices. Everything
else is assumed to be a "RTL8723B" which was originally supported by the
driver (communicating via USB).

The UART settings are embedded in the config blob. This has to be parsed
to successfully initialize the Bluetooth part of the RTL8723BS (which is
an SDIO chip, but the Bluetooth part is connected via UART).
The Realtek "rtl8723bs_bt" and "rtl8723ds_bt" userspace Bluetooth UART
initialization tools (rtk_hciattach) use the following sequence:
- send H5 sync pattern (already supported by hci_h5)
- get LMP version (already supported by btrtl)
- get ROM version (already supported by btrtl)
- load the firmware and config for the current chipset (already
supported by btrtl)
- read UART settings from the config blob (part of this patch)
- send UART settings via a vendor command to the device (which changes
the baudrate of the device and enables or disables flow control
depending on the config)
- change the baudrate and flow control settings on the host
- send the firmware and config blob to the device (already supported by
btrtl)
Sending the last firmware and config blob download command
(rtl_download_cmd) fails if the UART settings are not updated
beforehand. This is presumably because the device applies the config
right after the firmware and config blob download - which means that at
this point the host is using different UART settings than the device
(which will obviously result in non-working communication).

This prepares the btrtl code so it can be used to initialize Bluetooth
modules connected via UART (these are found for example on the RTL8723BS
and RTL8723DS SDIO chips, which come with an embedded UART Bluetooth
module).
The Realtek "rtl8723bs_bt" and "rtl8723ds_bt" userspace Bluetooth UART
initialization tools (rtk_hciattach) use the following sequence:
1) send H5 sync pattern (already supported by hci_h5)
2) get LMP version (already supported by btrtl)
3) get ROM version (already supported by btrtl)
4) load the firmware and config for the current chipset (already
supported by btrtl)
5) read UART settings from the config blob (currently not supported)
6) send UART settings via a vendor command to the device (which changes
the baudrate of the device and enables or disables flow control
depending on the config)
7) change the baudrate and flow control settings on the host
8) send the firmware and config blob to the device (already supported by
btrtl)
The main reason why the initialization has to be split is step #7. This
requires changes to the underlying "bus", which should be kept outside
of the "generic" btrtl driver.
The idea for this split is borrowed from the btbcm driver but adjusted
where needed (the btrtl driver for example needs two blobs: firmware and
config, while the btbcm only needs one).
This also prepares the code for step #5 (parsing the config blob) by
centralizing the code which loads the firmware and config blobs and
storing the result in the new struct btrtl_device_info.

GENERIC_IRQ_MULTI_HANDLER is incompatible with MULTI_IRQ_HANDLER because
they define the same symbols. Multiple generic irqchip drivers select
MULTI_IRQ_HANDLER, which is now defined on all architectures that
provide set_handle_irq().
To solve this select GENERIC_IRQ_MULTI_HANDLER for all drivers that used to
select MULTI_IRQ_HANDLER, but only when MULTI_IRQ_HANDLER doesn't exist.
After that every architecture can be converted over from MULTI_IRQ_HANDLER
to GENERIC_IRQ_MULTI_HANDLER before removing the extra MULTI_IRQ_HANDLER
scaffolding.

Should the PSP initialization fail, the PSP data structure will be
freed and the value contained in the sp_device struct set to NULL.
At module unload, psp_dev_destroy() does not check if the pointer
value is NULL and will end up dereferencing a NULL pointer.
Add a pointer check of the psp_data field in the sp_device struct
in psp_dev_destroy() and return immediately if it is NULL.

adf_dev_aer_schedule_reset()
adf_dev_aer_schedule_reset() is never called in atomic context, as it
calls wait_for_completion_timeout().
adf_dev_aer_schedule_reset() calls kzalloc() with GFP_ATOMIC,
which is not necessary.
GFP_ATOMIC can be replaced with GFP_KERNEL.

crypto_alloc_context()
crypto_alloc_context() is only called by nitrox_skcipher_init(), which is
never called in atomic context.
crypto_alloc_context() calls dma_pool_alloc() with GFP_ATOMIC,
which is not necessary.
GFP_ATOMIC can be replaced with GFP_KERNEL.

Issue description: Intel 7265 shares the same RF with Wifi and BT.
In the shutdown scenario turn off BT, followed by turn WiFi off
and on causing error in RF calibration in WiFi Module
Solution: before shutdown BT ensure any RF activity to clear by
HCI reset command.
