In case of an error (if there are not free PEB's for example),
__wl_get_peb will return a negative value. In order to prevent access
violation we need to test the returned value prior to using it later on.

The way that reset is handled right now is that it is made optional for every
pinctrl driver, while actually, it isn't used at all for the main pin
controllers so far, and while it's mandatory for the A31's secondary pin
controller.
Move the reset functions out of the core and in the driver, where they can be
made mandatory.

A frame starts with ST21NFCA_SOF_EOF(0x7e) + 0x00.
A frame ends with ST21NFCA_SOF_EOF(0x7e).
It is possible that the i2c macrocell is stopped for other
communication interfaces with highest priority(RF or SWP).
This can be seen with some 0xFF data at the end of a received shdlc buffer.
If this happen we need to discard the frame because the CLF will repeat it.
In order to push accurate data to hci layer, we add the following fix:
- Instead of looking for the first 0x7e in the frame, check that the last
received byte is 0x7e.
- Check that the first frame reception block start with start of
frame(0x7e 0x00). If not, clear the buffer.
- Check that the next frame reception block do not start with start of
frame(0x7e). If so, clear the buffer.

There is no byte stuffing when data are stored in skb.
TAILROOM is 2 byte crc + 1 byte eof.
st21nfca_hci_remove_len_crc was doing an incorrect operation on
the TAILROOM data.
If shdlc timer T2 is triggered, it will request to send the same data.
Before every hci data was lost after st21nfca_hci_remove_len_crc.

Pull arm64 fixes from Catalin Marinas:
"These are mostly arm64 fixes with an additional arm(64) platform fix
for the initialisation of vexpress clocks (the latter only affecting
arm64; the arch/arm64 code is SoC agnostic and does not rely on early
SoC-specific calls)
- vexpress platform clocks initialisation moved earlier following the
arm64 move of of_clk_init() call in a previous commit
- Default DMA ops changed to non-coherent to preserve compatibility
with 32-bit ARM DT files. The "dma-coherent" property can be used
to explicitly mark a device coherent. The Applied Micro DT file
has been updated to avoid DMA cache maintenance for the X-Gene SATA
controller (the only arm64 related driver with such assumption in
-rc mainline)
- Fixmap correction for earlyprintk
- kern_addr_valid() fix for huge pages"

interfaces. However, like all DMA-capable Marvell interface, they

It's caused by a silicon issue that SATA phy does not get reset by
controller when coming back from LPM. The patch adds a software
workaround for this issue. It enforces a software reset on SATA phy
in imx_sata_enable() function, so that we can ensure SATA link will
come up properly in both power-on and resume.
The software reset is implemented by writing phy reset register through
the phy control register bus interface. Functions
imx_phy_reg_[addressing|write|read]() implement this bus interface, while
imx_sata_phy_reset() performs the actually reset operation.

Following arm64 commit bc3ee18a7a57 (arm64: init: Move of_clk_init to
time_init()), vexpress_osc_of_setup() is called via of_clk_init() long
before initcalls are issued. Initialising the vexpress oscillators
requires the vespress sysregs to be already initialised, so this patch
adds an explicit call to vexpress_sysreg_of_early_init() in vexpress
oscillator setup function.

Move the pin description to a driver specific to be.
This is the final step toward retiring pinctrl-sunxi-pins.h that used to define
all the pins for all the Allwinner SoCs in a single header, that would have in
turn result in having these structures in the final binary as many times as the
header was included.
We can finally remove that header, and remove all the driver part of the
