d538990ee1 pinctrl: mvebu: armada-375: remove incorrect space in pin description
There was an incorrect space in the definition of the function of one
pin in the Armada 375 pinctrl driver, which this commit fixes.

There was a mistake in the definition of the functions for MPP48 on

80b3d04fea pinctrl: mvebu: armada-xp: remove non-existing VDD cpu_pd functions
The latest version of the Armada XP datasheet no longer documents the
VDD cpu_pd functions, which might indicate they are not working and/or
not supported. This commit ensures the pinctrl driver matches the

After updating to a more recent version of the Armada XP datasheet, we

331642fbf2 pinctrl: mvebu: armada-38x: fix PCIe functions
A new revision of the Marvell Armada 38x hardware datasheet unveiled
that the definition of some of the PCIe functions were not
correct. This commit fixes the pinctrl driver accordingly.

Some PCIe functions simply do not exist, some of the PCIe functions in
fact were corresponding to other functions, and some PCIe functions
have been added.

Note: the seemingly unrelated removal of spi(cs2) on MPP47 is related:
this function is in fact implemented on MPP43, instead of a PCIe
function.

1fc62c526a Bluetooth: Fix exposing full value of shortened LTKs
When we notify user space of a new LTK or distribute an LTK to the
remote peer the value passed should be the shortened version so that
it's easy to compare values in various traces. The core spec also sets
the requirements for the shortening/masking as:

"The masking shall be done after generation and before being

98a226ed21 ALSA: hda - Don't actually write registers for caps overwrites
Along with the transition to regmap for managing the cached parameter
reads, the caps overwrite was also moved to regmap cache.  The cache
change itself works, but it still tries to write the non-existing verb
(the HDA parameter is read-only) wrongly.  It's harmless in most
cases, but some chips are picky and may result in the codec
communication stall.

This patch avoids it just by adding the missing flag check in
reg_write ops.

all devices behind rtciobrg needs a special way to access. currently they
are using a platform-specific API.
this patch moves to REGMAP, then clients can use regmap APIs to read/write.
for the moment, old APIs are still kept, once all clients move to regmap,
old APIs will be dropped.

539f511365 x86/asm/entry/64: Disentangle error_entry/exit gsbase/ebx/usermode code
The error_entry/error_exit code to handle gsbase and whether we
return to user mdoe was a mess:

 - error_sti was misnamed.  In particular, it did not enable interrupts.

 - Error handling for gs_change was hopelessly tangled the normal
   usermode path.  Separate it out.  This saves a branch in normal
   entries from kernel mode.

 - The comments were bad.

Fix it up.  As a nice side effect, there's now a code path that
happens on error entries from user mode.  We'll use it soon.

1536bb46fa x86/asm/entry/32: Explain reloading of registers after __audit_syscall_entry()
Here it is not obvious why we load pt_regs->cx to %esi etc.
Lets improve comments.

Explain that here we combine two things: first, we reload
registers since some of them are clobbered by the C function we
just called; and we also convert 32-bit syscall params to 64-bit
C ABI, because we are going to jump back to syscall dispatch
code.

Move reloading of 6th argument into the macro instead of having
it after each of two macro invocations.

No actual code changes here.

This patch adds the CLK_SET_RATE_PARENT flag for 'aclk_g3d' clock and parent
clocks becuase 'aclk_g3d' is used to change GPU frequency for DVFS (Dynamic

7e49d6165e ixgbe: Set lan_id before using I2C
We need to call the set_lan_id before accessing I2C and this wasn't
being done so this patch corrects that.  Likewise we do the same for
QSFP just to be consistent.

In the X550 case this is even more important as with out it the mux
is not controlled properly.

This patch adds ixgbe_check_link_t_X550em for checking copper PHY
link.  We check that both the MAC and external PHY have link. This
is to avoid a false link up between the internal and external PHY
when  the external PHY doesn't have link.

e2261bcc2a ixgbe: fix X550 devices init flow
Reviewing the X550 copper init flow with the Si team resulted in a
new simplified flow.  We no longer wait for the PHY FW initialization
complete bit to be set as this bit is only set once by the PHY at power
on and then cleared on the first read. So only the first instance of
running SW (or possibly MAC FW) needs to initialize the PHY.

The PHY initialization has been simplified and now only requires that
the PHY FW be un-stalled
low-power mode or enabled the transceiver
