2020-10-04Input: add zinitix touchscreen driverMichael Srba3-0/+594
Add support for the bt541 touchscreen IC from zinitix, loosely based on downstream driver. The driver currently supports multitouch (5 touch points). The bt541 seems to support touch keys, but the support was not added because that functionality is not being utilized by the touchscreen used for testing. Based on the similartities between downstream drivers, it seems likely that other similar touchscreen ICs can be supported with this driver in the future.

2020-09-13Input: raydium_i2c_ts - use single i2c_transfer transaction when using RM_CMD_BANK_SWITCHFurquan Shaikh1-73/+58
On an AMD chromebook, where the same I2C bus is shared by both Raydium touchscreen and a trackpad device, it is observed that interleaving of I2C messages when `raydium_i2c_read_message()` is called leads to the Raydium touch IC reporting incorrect information. This is the sequence that was observed to result in the above issue: * I2C write to Raydium device for RM_CMD_BANK_SWITCH * I2C write to trackpad device * I2C read from trackpad device * I2C write to Raydium device for setting address * I2C read from Raydium device >>>> This provides incorrect information This change adds a new helper function `raydium_i2c_xfer()` that performs I2C transactions to the Raydium device. It uses the register address to decide if RM_CMD_BANK_SWITCH header needs to be sent to the device (i.e. if register address is greater than 255, then bank switch header is sent before the rest of the transaction). Additionally, it ensures that all the I2C operations performed as part of `raydium_i2c_xfer()` are done as a single i2c_transfer. This guarantees that no other transactions are initiated to any other device on the same bus in between. Additionally, `raydium_i2c_{send|read}*` functions are refactored to use this new helper function. Verified with the patch across multiple reboots (>100) that the information reported by the Raydium touchscreen device during probe is correct.

Samsung S3C24xx and S3C64xx machine code cleanup for v5.10 Big cleanup for the Samsung S3C24xx and S3C64xx platforms, although it also touches files shared with S5Pv210 and Exynos. This is mostly Arnd Bergmann work which Krzysztof Kozlowski took over, rebased and polished. The goal is to cleanup, merge and finally make the Samsung S3C24xx and S3C64xx architectures multiplatform. The multiplatform did not happen yet here - just cleaning up and merging into one arch/arm/mach-s3c directory. However this is step forward for multiplatform or at least to keep this code still maintainable. This pulls also branch with changes for Samsung SoC sound drivers from broonie/sound because the cleanups there were part of this series and all further patches depend on them. * tag 'samsung-soc-s3c-5.10' of https://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux: (62 commits) ARM: s3c: Avoid naming clash of S3C24xx and S3C64xx timer setup ARM: s3c: Cleanup from old plat-samsung include ARM: s3c: make headers local if possible ARM: s3c: move into a common directory ARM: s3c24xx: stop including mach/hardware.h from mach/io.h cpufreq: s3c24xx: move low-level clk reg access into platform code cpufreq: s3c2412: use global s3c2412_cpufreq_setrefresh ARM: s3c: remove cpufreq header dependencies cpufreq: s3c24xx: split out registers fbdev: s3c2410fb: remove mach header dependency ARM: s3c24xx: bast: avoid irq_desc array usage ARM: s3c24xx: spi: avoid hardcoding fiq number in driver ARM: s3c24xx: include mach/irqs.h where needed ARM: s3c24xx: move s3cmci pinctrl handling into board files ARM: s3c24xx: move iis pinctrl config into boards ARM: s3c24xx: move spi fiq handler into platform ARM: s3c: adc: move header to linux/soc/samsung ARM: s3c24xx: move irqchip driver back into platform ARM: s3c24xx: move regs-spi.h into spi driver ARM: s3c64xx: remove mach/hardware.h ...

2020-08-06Input: exc3000 - add support to query model and fw_versionSebastian Reichel1-1/+147
Expose model and fw_version via sysfs. Also query the model in probe to make sure, that the I2C communication with the device works before successfully probing the driver. This is a bit complicated, since EETI devices do not have a sync interface. Sending the commands and directly reading does not work. Sending the command and waiting for some time is also not an option, since there might be touch events in the mean time. Last but not least we do not cache the results, since this interface can be used to check the I2C communication is still working as expected.

The workaround of reading all messages until an invalid is received is a way of forcing the CHG line high, which means that when using edge-triggered interrupts the interrupt can be acquired. With level-triggered interrupts the workaround is unnecessary. Also, most recent maXTouch chips have a feature called RETRIGEN which, when enabled, reasserts the interrupt line every cycle if there are messages waiting. This also makes the workaround unnecessary. Note: the RETRIGEN feature is only in some firmware versions/chips, it's not valid simply to enable the bit.

This patch applies the semantic patch: @@ expression I, P, SP; @@ I = devm_iio_device_alloc(P, SP); ... - I->dev.parent = P; It updates 302 files and does 307 deletions. This semantic patch also removes some comments like '/* Establish that the iio_dev is a child of the i2c device */' But this is is only done in case where the block is left empty. The patch does not seem to cover all cases. It looks like in some cases a different variable is used in some cases to assign the parent, but it points to the same reference. In other cases, the block covered by ... may be just too big to be covered by the semantic patch. However, this looks pretty good as well, as it does cover a big bulk of the drivers that should remove the parent assignment.

2020-05-09Input: add driver for the Cypress CY8CTMA140 touchscreenLinus Walleij3-0/+366
This adds a new driver for the Cypress CY8CTMA140 touchscreen. This driver is inspired by out-of-tree code for the Samsung GT-S7710 mobile phone. I have tried to compare the structure and behaviour of this touchscreen to the existing CYTTSP and CYTTSP4 generics and it seems pretty different. It is also different in character from the cy8ctmg110_ts.c. It appears to rather be vaguely related to the Melfas MMS114 driver, yet distinctly different. Dmitry Torokhov rewrote the key scanning code during the submission process so the driver is a joint work.

2020-05-09Input: edt-ft5x06 - improve power management operationsMarco Felsch1-10/+132
It is possible to bring the device into a deep sleep state. To exit this state the reset or wakeup pin must be toggeled as documented in [1]. Because of the poor documentation I used the several downstream kernels [2] and other applications notes [3] to indentify the related registers. Furthermore I added the support to disable the device completely which is obviously the most effective power-saving mechanism. This mechanism needs the reset pin to ensure the power-up/down sequence. We can't apply any of these power-saving mechanism if both pins are missing (not connected) or if it is a wakeup device.

2020-04-25Input: mms114 - add extra compatible for mms345lStephan Gerhold1-2/+15
MMS345L is another first generation touch screen from Melfas, which uses mostly the same registers as MMS152. However, there is some garbage printed during initialization. Apparently MMS345L does not have the MMS152_COMPAT_GROUP register that is read+printed during initialization. TSP FW Rev: bootloader 0x6 / core 0x26 / config 0x26, Compat group: \x06 On earlier kernel versions the compat group was actually printed as an ASCII control character, seems like it gets escaped now. But we probably shouldn't print something from a random register. Add a separate "melfas,mms345l" compatible that avoids reading from the MMS152_COMPAT_GROUP register. This might also help in case there is some other device-specific quirk in the future.
