Our current writing function accesses PHY directly bypassing MDIO layer.
The aim is to extend this module to also behave as MDIO driver. This
will require using different writing function which can be handled
cleanly by having an extra pointer like this.

Move MDIO specific code to the writing helper function. This makes init
code a bit more generic and doesn't require it to track what happens
after every write.

Commit 8ae904e3c236 ("phy: cpcap-usb: Add CPCAP PMIC USB support")
is missing return statement as noted by Colin Ian King
<colin.king@canonical.com>. If the optional pins are not configured,
we just want to return early and not attempt to configure the pins.

This is driver for USB DRD PHY used in Broadcom's Northstar2
SoC. The phy can be configured to be in Device mode or Host
mode based on the type of cable connected to the port. The
driver registers to extcon framework to get appropriate
connect events for Host/Device cables connect/disconnect
states based on VBUS and ID interrupts.

When MUSB is a loadable module, we get a link error for a built-in
CPCAP driver:
drivers/phy/built-in.o: In function `cpcap_usb_phy_remove':
phy-cpcap-usb.c:(.text+0xed9): undefined reference to `musb_mailbox'
This adds a Kconfig dependency to prevent this broken configuration,
enforcing that CPCAP can only be a module when MUSB is also a module.

The USB 3.0 PHY modules of R-Car Gen3 SoCs have:
- Spread spectrum clock (ssc).
- Using USB 2.0 EXTAL clock instead of USB 3.0 clock.
- Enabling VBUS detection for usb3.0 peripheral.
So, this driver supports these features.

At the current rockchip-inno-usb2 phy driver framework, it can
only support usb2-phy which comprises with one otg-port and one
host-port.
However, some Rockchip SoCs' (e.g RK3228, RK3229) usb2-phy comprises
with two host-ports, so we use index of otg id for one host-port
configuration, and make it work the same as otg-port host mode.

In rockchip-inno-usb2 phy driver, we use otg_sm_work to
dynamically manage power consumption for phy otg-port.
If the otg-port works as peripheral mode and does not
communicate with usb host, we will suspend phy.
But once suspend phy, the phy no longer has any internal
clock running, include the utmi_clk which supplied for
usb controller. So if we suspend phy before usb controller
init, it will cause usb controller fail to initialize.
Specifically, without this patch, the observed order is:
1. unplug usb cable
2. start system, do dwc2 controller probe
3. dwc2_lowlevel_hw_enable()
- phy_init()
- rockchip_usb2phy_init()
- schedule otg_sm_work after 2s
put phy in suspend, and close utmi_clk
4. dwc2_hsotg_udc_start() - fail to initialize the usb core
Generally, dwc2_hsotg_udc_start() can be called within 5s
after start system on Rockchip platform, so we increase the
the first schedule delay time to 6s for otg_sm_work afer usb
controller calls phy_init(), this can make sure that the usb
controller completes initialization before phy enter suspend.

Some Motorola phones like droid 4 use a custom CPCAP PMIC that has a
multiplexing USB PHY.
This USB PHY can operate at least in four modes using pin multiplexing
and two control GPIOS:
- Pass through companion PHY for the SoC USB PHY
- ULPI PHY for the SoC
- Pass through USB for the modem
- UART debug console for the SoC
This patch adds support for droid 4 USB PHY and debug UART modes,
support for other modes can be added later on as needed.
Both peripheral and host mode are working for the USB. The
host mode depends on the cpcap-charger driver for VBUS.
VBUS and ID pin detection are done using cpcap-adc IIO ADC
driver.

This adds a new driver for the USB2 PHYs found on Meson GXL and GXM SoCs
(both SoCs are using the same USB PHY register layout).
The USB2 PHY is a simple PHY which only has a few registers to configure
the mode (host/device) and a reset register (to enable/disable the PHY).
Unfortunately there are no datasheets available for this PHY. The driver
was written by reading the code from Amlogic's GPL kernel sources and
by analyzing the registers on an actual GXL and GXM device running the
kernel that was shipped on the boards I have.

The userspace xboxdrv driver [0] contains some USB IDs unknown to the

A quick google search confirmed that all the new devices called
Fightstick/pad are Arcade-type devices [2] where the
MAP_TRIGGERS_TO_BUTTONS option should apply.
There are some similar devices in the existing device table where this
flag is not set, but I did refrain from changing those.

Booting with UBI fastmap and SLUB debugging enabled results in the
following splats. The problem is that ubi_scan_fastmap() moves the
fastmap blocks from the scan_ai (allocated in scan_fast()) to the ai
allocated in ubi_attach(). This results in two problems:
- When the scan_ai is freed, aebs which were allocated from its slab
cache are still in use.
- When the other ai is being destroyed in destroy_ai(), the
arguments to kmem_cache_free() call are incorrect since aebs on its
->fastmap list were allocated with a slab cache from a differnt ai.
Fix this by making a copy of the aebs in ubi_scan_fastmap() instead of
moving them.

When write syscall is called, every time security label is searched to
determine that file's privileges should be changed.
If LSM(Linux Security Model) is not used, this is useless.
So introduce CONFIG_UBIFS_SECURITY to disable security labels. it's default
value is "y".

WARNING: vmlinux.o(.text+0x1f2a80): Section mismatch in reference from the variable __param_ops_mtd to the function .init.text:ubi_mtd_param_parse()
The function __param_ops_mtd() references
the function __init ubi_mtd_param_parse().
This is often because __param_ops_mtd lacks a __init
annotation or the annotation of ubi_mtd_param_parse is wrong.

um: Add missing NR_CPUS include
um: Fix to call read_initrd after init_bootmem
um: Include kbuild.h instead of duplicating its macros
um: Fix PTRACE_POKEUSER on x86_64
um: Set number of CPUs
um: Fix _print_addr()

Since read_initrd() invokes alloc_bootmem() for allocating
memory to load initrd image, it must be called after init_bootmem.
This makes read_initrd() called directly from setup_arch()
after init_bootmem() and mem_total_pages().

This is broken since ever but sadly nobody noticed.
Recent versions of GDB set DR_CONTROL unconditionally and
UML dies due to a heap corruption. It turns out that
the PTRACE_POKEUSER was copy&pasted from i386 and assumes
that addresses are 4 bytes long.
Fix that by using 8 as address size in the calculation.
