2021-03-04Input: i8042 - add ASUS Zenbook Flip to noselftest listMarcos Paulo de Souza1-0/+4
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 Torvalds1-1/+3
[ 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.

2021-01-02Input: st1232 - wait until device is ready before reading resolutionGeert Uytterhoeven1-0/+35
According to the st1232 datasheet, the host has to wait for the device to change into Normal state before accessing registers other than the Status Register. If the reset GPIO is wired, the device is powered on during driver probe, just before reading the resolution. However, the latter may happen before the device is ready, leading to a probe failure: st1232-ts 1-0055: Failed to read resolution: -6 Fix this by waiting until the device is ready, by trying to read the Status Register until it indicates so, or until timeout. On Armadillo 800 EVA, typically the first read fails with an I2C transfer error, while the second read indicates the device is ready.

st1232_ts_read_data() already reads ts->read_buf_len bytes (8 or 20 bytes) from the touchscreen controller.

Before, the maximum coordinates were fixed to (799, 479) or (319, 479), depending on touchscreen controller type. The driver was changed to read the actual values from the touchscreen controller, but did not take into account the returned values are not the maximum coordinates, but the touchscreen resolution (e.g. 800 and 480).

If device is set up as a wakeup source, I2C core configures the interrupt line as wake IRQ and PM core automatically configures it for waking up the system on system suspend transition, so we do not have to explicitly call enable_irq_wake() and disable_irq_wake() in suspend/resume.

We should not be configuring the controller as a wakeup source in the driver, but rather rely on I2C core to mark it as such by either instantiating as I2C_CLIENT_WAKEUP or specifying "wakeup-source" device property.

Also mark "report rate" register as non-existent for generic firmwares as having it set to 0 does not make sense.

The Samsung touchkey controllers are often used with external pull-up for the interrupt line and the I2C lines, so we might need to enable a regulator to bring the lines into usable state. Otherwise, this might cause spurious interrupts and reading from I2C will fail. Implement support for a "vddio-supply" that is enabled by the tm2-touchkey driver so that the regulator gets enabled when needed.
