2021-05-11Input: ili210x - add missing negation for touch indication on ili210xHansem Ro
commit ac05a8a927e5a1027592d8f98510a511dadeed14 upstream. This adds the negation needed for proper finger detection on Ilitek ili2107/ili210x. This fixes polling issues (on Amazon Kindle Fire) caused by returning false for the cooresponding finger on the touchscreen.

commit 30b3f68715595dee7fe4d9bd91a2252c3becdf0a upstream. The touch coordinate register contains the following: byte 3 byte 2 byte 1 +--------+--------+ +-----------------+ +-----------------+ | | | | | | | | X[3:0] | Y[3:0] | | Y[11:4] | | X[11:4] | | | | | | | | +--------+--------+ +-----------------+ +-----------------+ Bytes 2 and 1 need to be shifted left by 4 bits, the least significant nibble of each is stored in byte 3. Currently they are only being shifted by 3 causing the reported coordinates to be incorrect. This matches downstream examples, and has been confirmed on my device (OnePlus 7 Pro).

2021-04-21Input: nspire-keypad - enable interrupts only when openedFabian Vogt
[ Upstream commit 69d5ff3e9e51e23d5d81bf48480aa5671be67a71 ] The driver registers an interrupt handler in _probe, but didn't configure them until later when the _open function is called. In between, the keypad can fire an IRQ due to touchpad activity, which the handler ignores. This causes the kernel to disable the interrupt, blocking the keypad from working. Fix this by disabling interrupts before registering the handler. Additionally, disable them in _close, so that they're only enabled while open.

[ Upstream commit 0ce1ac23149c6da939a5926c098c270c58c317a0 ] The response to a command may never arrive or it may be corrupted (and hence dropped) for some reason. While exceedingly rare, when it did happen it blocked all further commands. One way to fix this was to do a suspend/resume. However, recovering automatically seems like a nicer option. Hence this puts a time limit (1 sec) on how long we're willing to wait for a response, after which we assume it got lost.

commit b5d6e7ab7fe7d186878142e9fc1a05e4c3b65eb9 upstream. After commit 77b425399f6d ("Input: i8042 - use chassis info to skip selftest on Asus laptops"), all modern Asus laptops have the i8042 selftest disabled. It has done by using chassys type "10" (laptop). The Asus Zenbook Flip suffers from similar suspend/resume issues, but it _sometimes_ work and sometimes it doesn't. Setting noselftest makes it work reliably. In this case, we need to add chassis type "31" (convertible) in order to avoid selftest in this device.

2021-03-04tty: convert tty_ldisc_ops 'read()' function to take a kernel pointerLinus Torvalds
[ Upstream commit 3b830a9c34d5897be07176ce4e6f2d75e2c8cfd7 ] The tty line discipline .read() function was passed the final user pointer destination as an argument, which doesn't match the 'write()' function, and makes it very inconvenient to do a splice method for ttys. This is a conversion to use a kernel buffer instead. NOTE! It does this by passing the tty line discipline ->read() function an additional "cookie" to fill in, and an offset into the cookie data. The line discipline can fill in the cookie data with its own private information, and then the reader will repeat the read until either the cookie is cleared or it runs out of data. The only real user of this is N_HDLC, which can use this to handle big packets, even if the kernel buffer is smaller than the whole packet.

Forgetting to pm_runtime_put_noidle will result in reference leak. 2) In err_unmap, forget to disable runtime of device, pm_runtime_enable will increase power disable depth. Thus a pairing decrement is needed on the error handling path to keep it balanced. 3) In err_pm_disable, it will call pm_runtime_put_sync twice not one time.

Raydium device does not like splitting of tx transactions into multiple messages - one for the register address and one for the actual data. This results in incorrect behavior on the device side. This change updates raydium_i2c_read and raydium_i2c_write to create i2c_msg arrays separately and passes those arrays into raydium_i2c_xfer which decides based on the address whether the bank switch command should be sent. The bank switch header is still added by raydium_i2c_read and raydium_i2c_write to ensure that all these operations are performed as part of a single I2C transfer. It guarantees that no other transactions are initiated to any other device on the same bus after the bank switch command is sent.

2020-12-01Input: atmel_mxt_ts - fix lost interruptsLinus Walleij
After commit 74d905d2d38a devices requiring the workaround for edge triggered interrupts stopped working. The hardware needs the quirk to be used before even proceeding to check if the quirk is needed because mxt_acquire_irq() is called before mxt_check_retrigen() is called and at this point pending IRQs need to be checked, and if the workaround is not active, all interrupts will be lost from this point. Solve this by switching the calls around.

2020-10-26Input: i8042 - allow insmod to succeed on devices without an i8042 controllerHans de Goede
The i8042 module exports several symbols which may be used by other modules. Before this commit it would refuse to load (when built as a module itself) on systems without an i8042 controller. This is a problem specifically for the asus-nb-wmi module. Many Asus laptops support the Asus WMI interface. Some of them have an i8042 controller and need to use i8042_install_filter() to filter some kbd events. Other models do not have an i8042 controller (e.g. they use an USB attached kbd). Before this commit the asus-nb-wmi driver could not be loaded on Asus models without an i8042 controller, when the i8042 code was built as a module (as Arch Linux does) because the module_init function of the i8042 module would fail with -ENODEV and thus the i8042_install_filter symbol could not be loaded. This commit fixes this by exiting from module_init with a return code of 0 if no controller is found. It also adds a i8042_present bool to make the module_exit function a no-op in this case and also adds a check for i8042_present to the exported i8042_command function. The latter i8042_present check should not really be necessary because when builtin that function can already be used on systems without an i8042 controller, but better safe then sorry.

2020-10-22hil/parisc: Disable HIL driver when it gets stuckHelge Deller
When starting a HP machine with HIL driver but without an HIL keyboard or HIL mouse attached, it may happen that data written to the HIL loop gets stuck (e.g. because the transaction queue is full). Usually one will then have to reboot the machine because all you see is and endless output of: Transaction add failed: transaction already queued? In the higher layers hp_sdc_enqueue_transaction() is called to queued up a HIL packet. This function returns an error code, and this patch adds the necessary checks for this return code and disables the HIL driver if further packets can't be sent. Tested on a HP 730 and a HP 715/64 machine. Signed-off-by: Helge Deller <deller@gmx.de> Cc: <stable@vger.kernel.org>
