Reported the cleared bytes in case of a partial clear_user instead
of -EFAULT, and remove a pointless conditional, as cleared must be

e2435d6920 drm/bridge: dw-mipi-dsi.c: Add VPG runtime config through debugfs
Add support for the video pattern generator (VPG) BER pattern mode and
configuration in runtime.

This enables using the debugfs interface to manipulate the VPG after
the pipeline is set.
Also, enables the usage of the VPG BER pattern.

Changes in v2:
  - Added VID_MODE_VPG_MODE
  - Solved incompatible return type on __get and __set

6a953dc4db mwifiex: Remove unnecessary braces from HostCmd_SET_SEQ_NO_BSS_INFO
A new warning in clang points out when macro expansion might result in a
GNU C statement expression. There is an instance of this in the mwifiex
driver:

drivers/net/wireless/marvell/mwifiex/cmdevt.c:217:34: warning: '}' and
')' tokens terminating statement expression appear in different macro
expansion contexts [-Wcompound-token-split-by-macro]
        host_cmd->seq_num = cpu_to_le16(HostCmd_SET_SEQ_NO_BSS_INFO
                                        ^~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/net/wireless/marvell/mwifiex/fw.h:519:46: note: expanded from
macro 'HostCmd_SET_SEQ_NO_BSS_INFO'
        (((type) & 0x000f) << 12);                  }
                                                    ^

This does not appear to be a real issue. Removing the braces and
replacing them with parentheses will fix the warning and not change the
meaning of the code.

c6d94e37bd drm/bridge/synopsys: dsi: add support for non-continuous HS clock
Current code enables the HS clock when video mode is started or to
send out a HS command, and disables the HS clock to send out a LP
command. This is not what DSI spec specify.

Enable HS clock either in command and in video mode.
Set automatic HS clock management for panels and devices that
support non-continuous HS clock.

9e025e8066 drm/bridge/synopsys: dsi: allow sending longer LP commands
Current code does not properly computes the max length of LP
commands that can be send during H or V sync, and rely on static
values.
Limiting the max LP length to 4 byte during the V-sync is overly
conservative.

Relax the limit and allows longer LP commands (16 bytes) to be
sent during V-sync.

0f93db6542 mmc: renesas_sdhi: keep SCC clock active when tuning
Tuning procedure switches to lower frequencies but that will turn the
SCC off and accessing its register then will hang. So, check when we are
tuning and keep the current setup of the external clock if we are doing
so. Note that we still switch to the lower frequency because of the
internal divider. We just make sure to not modify the external clock.
This patch depends on a MMC core patch calling the downgrade function
earlier.

97a7d87e96 mmc: core: add a 'doing_init_tune' flag and a 'mmc_doing_tune' helper
Our driver needs to know when tuning is in progress. 'doing_retune' only
covers re-tuning, not the initial tuning. Add another flag to detect the
initial tuning state and add a helper which tells us if any kind of
tuning is going on. Only implemented for MMC currently because that's
where we need it. SD can be added later if it becomes necessary.

8c98644bfc mmc: sdhci-msm: Prefer asynchronous probe
Turning on initcall debug on one system showed this:
  initcall sdhci_msm_driver_init+0x0/0x28 returned 0 after 34782 usecs

The lion's share of this time (~33 ms) was in mmc_power_up().  This
shouldn't be terribly surprising since there are a few calls to delay
based on "power_delay_ms" and the default delay there is 10 ms.

Because we haven't specified that we'd prefer asynchronous probe for
this driver then we'll wait for this driver to finish before we start
probes for more drivers.  While 33 ms doesn't sound like tons, every
little bit counts.

There should be little problem with turning on asynchronous probe for
this driver.  It's already possible that previous drivers may have
turned on asynchronous probe so we might already have other things
(that probed before us) probing at the same time we are anyway.  This
driver isn't really providing resources (clocks, regulators, etc) that
other drivers need to probe and even if it was they should be handling
-EPROBE_DEFER.

Let's turn this on and get a bit of boot speed back.

fa2d0aa969 mmc: core: Allow setting slot index via device tree alias
As with GPIO, UART and others, allow specifying the device index via the
aliases node in the device tree.

On embedded devices, there is often a combination of removable (e.g.
SD card) and non-removable MMC devices (e.g. eMMC).
Therefore the index might change depending on

* host of removable device
* removable card present or not

This makes it difficult to hardcode the root device, if it is on the
non-removable device. E.g. if SD card is present eMMC will be mmcblk1,
if SD card is not present at boot, eMMC will be mmcblk0.

Alternative solutions like PARTUUIDs do not cover the case where multiple
mmcblk devices contain the same image. This is a common issue on devices
that can boot both from eMMC (for regular boot) and SD cards (as a
temporary boot medium for development). When a firmware image is
installed to eMMC after a test boot via SD card, there will be no
reliable way to refer to a specific device using (PART)UUIDs oder
LABELs.

The demand for this feature has led to multiple attempts to implement
it, dating back at least to 2012 (see
https://www.spinics.net/lists/linux-mmc/msg26586.html for a previous
discussion from 2014).

All indices defined in the aliases node will be reserved for use by the
respective MMC device, moving the indices of devices that don't have an
alias up into the non-reserved range. If the aliases node is not found,
the driver will act as before.

This is a rebased and cleaned up version of
https://www.spinics.net/lists/linux-mmc/msg26588.html .
