c3370de64d Bluetooth: Expose current Device ID information via debugfs
For debugging purposes it is good to be able to read the current
configured Device ID details.

b55d1abf56 Bluetooth: Expose quirks through debugfs
This patch expose controller quirks through debugfs. It would be
useful for BlueZ tests using vhci. Currently there is no way to
test quirk dependent behaviour. It might be also useful for manual
testing.

b880ab869c Bluetooth: The P-256 randomizer is 16 octets long and not 19 octets
This seems to be a simple typo in the debugfs entry for the remote
out-of-band data entries.

b7cb93e528 Bluetooth: Merge hdev->dbg_flags fields into hdev->dev_flags
With the extension of hdev->dev_flags utilizing a bitmap now, the space
is no longer restricted. Merge the hdev->dbg_flags into hdev->dev_flags
to save space on 64-bit architectures. On 32-bit architectures no size
reduction happens.

Instead of manually coding test_bit on hdev->dev_flags all the time,
use hci_dev_test_flag helper macro.

6858bcd073 Bluetooth: Expose remote OOB information as debugfs entry
For debugging purposes it is good to know which OOB data is actually
currently loaded for each controller. So expose that list via debugfs.

5789f37cbc Bluetooth: Expose hardware error code as debugfs entry
When the Hardware Error event is send by the controller, the Bluetooth
core stores the error code. Expose it via debugfs so it can be retrieved
later on.

6e07231a80 Bluetooth: Expose Secure Simple Pairing debug mode setting in debugfs
The value of the ssp_debug_mode should be accessible via debugfs to be
able to determine if a BR/EDR controller generates debugs keys or not.

cb0d2faeb1 Bluetooth: Fix scope of sc_only_mode debugfs entry
The sc_only_mode debugfs entry is used to read the current state of the
Secure Connections Only mode. Before Bluetooth 4.2 this mode was only
for BR/EDR controllers and with that tight to the support Secure Simple
Pairing. Since Secure Connections is now available for BR/EDR and LE
this debugfs entry is no longer correctly place.

Move it to the common section and enable it when either BR/EDR Secure
Connections feature is supported or when the controller has LE support.

05b3c3e790 Bluetooth: Remove no longer needed force_sc_support debugfs option
The force_sc_support debugfs option was introduced to easily work with
pre-production Bluetooth 4.1 silicon. This option is no longer needed
since controllers supporting BR/EDR Secure Connections feature are now
available.

91389af67c Bluetooth: Remove broken force_lesc_support debugfs option
The force_lesc_support debugfs option never really worked. It has a race
condition between creating the debugfs entry and registering the L2CAP
fixed channel for BR/EDR SMP support.

Also this has been replaced with a working force_bredr_smp debugfs
switch that developers can use now.

60c5f5fb1f Bluetooth: Add skeleton functions for debugfs creation
The debugfs file creation has been part of the core initialization
handling of controllers. With the introduction of Bluetooth 4.2 core
specification, the number of debugfs files is increasing even further.

To avoid cluttering the core controller handling, create a separate
file hci_debugfs.c to centralize all debugfs file creation. For now
leave the current files in the core, but in the future all debugfs
file creation will be moved.
