This brings in fix for F03 build error when serio is module.
|
|
Since F03 is a boolean, "depends" on symbols that can be modules
do not work quite right. We can enable F03 if SERIO is built-in or
if both RMI core and SERIO core are modules. If SERIO core is module,
but RMI is built-in, we'll get:
drivers/built-in.o: In function `rmi_f03_attention':
rmi_f03.c:(.text+0xf8ef8): undefined reference to `serio_interrupt'

currently the controllers get the same product id as the wireless
receiver. However the controllers actually have their own product id.
The patch makes the driver expose the same product id as the windows
driver.
This improves compatibility when running applications with WINE.

ktime_set(S,N) was required for the timespec storage type and is still
useful for situations where a Seconds and Nanoseconds part of a time value
needs to be converted. For anything where the Seconds argument is 0, this
is pointless and can be replaced with a simple assignment.

The error message "Can't read CTR while initializing i8042" appears on
Cherry Trail-based devices at each boot time:
i8042: PNP: No PS/2 controller found. Probing ports directly.
i8042: Can't read CTR while initializing i8042
i8042: probe of i8042 failed with error -5
This happens because we historically do not trust firmware on X86 and,
while noting that PNP does not show keyboard or mouse devices, we still
charge ahead and try to probe the controller. Let's relax this a bit and if
results of PNP probe agree with the results of platform
initialization/quirks conclude that there is, in fact, no i8042.
While at it, let's avoid using x86_platform.i8042_detect() and instead
abort execution early if platform indicates that it can not possibly have
i8042 (x86_platform.legacy.i8042 equals X86_LEGACY_I8042_PLATFORM_ABSENT).

msleep(1~20) may not do what the caller intends, and will often sleep longer.
(~20 ms actual sleep for any value given in the 1~20ms range)
This is not the desired behaviour for many cases like device resume time,
device suspend time, device enable time, retry logic, etc.
Thus, change msleep to usleep_range for precise wakeups.

Pull sound updates from Takashi Iwai:
"No dramatic changes are found in this development cycle, but as usual,
many commits are applied in a wide range of drivers.
Most of big changes are in ASoC, where a few bits of framework work
and quite a lot of cleanups and improvements to existing code have
been done. The rest are usual stuff, a few HD-audio and USB-audio
quirks and fixes, as well as the drop of kthread usages in the whole
subsystem.
Below are some highlights:
ASoC:
- support for stereo DAPM controls
- some initial work on the of-graph sound card
- regmap conversions of the remaining AC'97 drivers
- a new version of the topology ABI; this should be backward
compatible
- updates / cleanups of rsnd, sunxi, sti, nau8825, samsung, arizona,
Intel skylake, atom-sst
- new drivers for Cirrus Logic CS42L42, Qualcomm MSM8916-WCD, and
Realtek RT5665
USB-audio:
- yet another race fix at disconnection
- tolerated packet size calculation for some Android devices
- quirks for Axe-Fx II, QuickCam, TEAC 501/503
HD-audio:
- improvement of Dell pin fixup mapping
- quirks for HP Z1 Gen3, Alienware 15 R2 2016 and ALC622 headset mic
Misc:
- replace all kthread usages with simple works"

Update driver drv260x to use generic device properties so that it can be
used on non-DT systems. We also remove platform data as generic device
properties work on static board code as well.

We were assigning I2C bus controller instead of client as parent device.
Besides being logically wrong, it messed up with devm handling of input
device. As a result we were leaving input device and event node behind
after rmmod-ing the driver, which lead to a kernel oops if one were to
access the event node later.
Let's remove the assignment and rely on devm_input_allocate_device() to
set it up properly for us.

Semantics of NR_IRQS is different on machines with SPARSE_IRQ option
disabled or enabled, in the latter case IRQs are allocated starting
at least from the value specified by NR_IRQS and going upwards, so
the check of (irq >= NR_IRQ) to decide about an error code returned by
platform_get_irq() is completely invalid, don't attempt to overrule
irq subsystem in the driver.
The change fixes lpc32xx_keys driver initialization on boot:
lpc32xx_keys 40050000.key: failed to get platform irq
lpc32xx_keys: probe of 40050000.key failed with error -22

The HID implementation of RMI4 provides the data during
the interrupt (in the input report). We need to provide
a way for this transport driver to provide the attention
data while calling an IRQ.
We use a fifo in rmi_core to not lose any incoming event.

First check if there are data available passed by the transport device.
If data available use these data. If there are no data available
try to read the rmi block if dsata are passed this way.
This is the way the other rmi function handlers will do this.
This patch is needed on HID devices because the firmware reads F03 data
registers and adds them to the HID attention report. Reading those
registers from the driver after the firmware read them will result in
invalid data.

The name of a codec pin can have an optional prefix string, which is
defined by the SoC machine driver. The snd_soc_dapm_x_pin functions
take the fully-specified name including the prefix and so the existing
code would fail to find the pin if the audio machine driver had added
a prefix.
Switch to using the snd_soc_component_x_pin equivalent functions that
take a specified SoC component and automatically add the name prefix to
the provided pin name.

Pull input fixes from Dmitry Torokhov: "We are disabling automatic
probing of BYD touchpads as it results in too many false positives,
and the hardware is not terribly popular and having the protocol
support does not result in significantly improved user experience.
We also change keycode for KEY_DATA to avoid clashing with
KEY_FASTREVERSE. Luckily this newish code is used by CEC framework
that is still in staging, so it is extremely unlikely that someone has
already started using this keycode"
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:

The code uses of_property_read_u32 and expects positive values. However,
the values are stored in signed int variables. Additionally, the registers
values are also stored in signed variables without a good reason
(readl/writel expect u32).
The only time this caused a real bug was in the new average-samples
property, in which the property is numerically compared and implicitly
expected to be positive.
I believe it's better to change all the properties and registers to u32,
for consistency and warnings reduction.

add support for F34 device reflash")
irq_mutex should be used only to protect data->current_irq_mask, not
preventing incoming input to be processed while the upgrade of the
firmware is happening. We can simply disable the irqs when we don't
want them to interfere with the upgrade process.

Using regmap_update_bits(..., mask, 1) with 'mask' following (1 << k)
and k greater than 0 is wrong. Indeed, _regmap_update_bits will perform
(mask & 1), which results in 0 if LSB of mask is 0. Thus the call
regmap_update_bits(..., mask, 1) is in reality equivalent to
regmap_update_bits(..., mask, 0).
In such a case, the correct use is regmap_update_bits(..., mask, mask).
This driver is performing such a mistake with the DRV2667_STANDBY mask,
which equals (1 << 6). Fix the driver to make it consistent with the
API, and fix the alignment problem at the same time. Please note that
this change is untested, as I do not have this piece of hardware.

The return value of alps_get_pkt_id_ss4_v2() should really be "enum
SS4_PACKET_ID", not "unsigned char". Correct this.
Also, most of the Alps SS5 (SS4 v2) packet byte parsing code is implemented
using macros, but there are a few places where bytes are directly
manipulated in alps.c. For consistency, migrate the rest of these to
macros.

The current Alps SS5 (SS4 v2) code generates bogus TouchPad events when
TrackStick packets are processed.
This causes the xorg synaptics driver to print
"unable to find touch point 0" and
"BUG: triggered 'if (priv->num_active_touches > priv->num_slots)'"
messages. It also causes unexpected TouchPad button release and re-click
event sequences if the TrackStick is moved while holding a TouchPad
button.
This commit corrects the problem by adjusting alps_process_packet_ss4_v2()
so that it only sends TrackStick reports when processing TrackStick
packets.
