Refactor the tas2770_set_samplerate to simplify the code and access the I2C bus only once per rate request.

2020-09-21ASoC: tlv320aic32x4: Enable fast chargeMiquel Raynal
At power-up the analog circuits may take up to one full second before being charged with the default configuration. Using the analog blocks before they are ready generates a *very* crappy sound. Enable the fast charge feature, which will require a bit more power than normal charge but will definitely speed up the starting operation by shrinking this delay to up to 40 ms.

2020-09-21pinctrl: cherryview: Preserve CHV_PADCTRL1_INVRXTX_TXDATA flag on GPIOsHans de Goede
One some devices the GPIO should output the inverted value from what device-drivers / ACPI code expects. The reason for this is unknown, perhaps these systems use an external buffer chip on the GPIO which inverts the signal. The BIOS makes this work by setting the CHV_PADCTRL1_INVRXTX_TXDATA flag. Before this commit we would unconditionally clear all INVRXTX flags, including the CHV_PADCTRL1_INVRXTX_TXDATA flag when a GPIO is requested by a driver (from chv_gpio_request_enable()). This breaks systems using this setup. Specifically it is causing problems for systems with a goodix touchscreen, where the BIOS sets the INVRXTX_TXDATA flag on the GPIO used for the touchscreen's reset pin. The goodix touchscreen driver by defaults configures this pin as input (relying on the pull-up to keep it high), but the clearing of the INVRXTX_TXDATA flag done by chv_gpio_request_enable() causes it to be driven low for a brief time before the GPIO gets set to input mode. This causes the touchscreen controller to get reset. On most CHT devs with this touchscreen this leads to: [ 31.596534] Goodix-TS i2c-GDIX1001:00: i2c test failed attempt 1: -121 The driver retries this though and then everything is fine. But during reset the touchscreen uses its interrupt pin as bootstrap to determine which i2c address to use and on the Acer One S1003 the spurious reset caused by the clearing of the INVRXTX_TXDATA flag causes the controller to come back up again on the wrong i2c address, breaking things. This commit fixes both the -121 errors, as well as the total breakage on the Acer One S1003, by making chv_gpio_clear_triggering() not clear the INVRXTX_TXDATA flag if the pin is already configured as a GPIO. Note that chv_pinmux_set_mux() does still unconditionally clear the flag, so this only affects GPIO usage.

2020-09-21spi: fsl-espi: Only process interrupts for expected eventsChris Packham
The SPIE register contains counts for the TX FIFO so any time the irq handler was invoked we would attempt to process the RX/TX fifos.

2020-09-21cpuidle: psci: Fix suspicious RCU usageUlf Hansson
The commit eb1f00237aca ("lockdep,trace: Expose tracepoints"), started to expose us for tracepoints. This lead to the following RCU splat on an ARM64 Qcom board.

Therefore, let's simply silence the splat by informing the RCU about it with RCU_NONIDLE. Note that, this is a temporary solution. Instead we should strive to avoid using RCU_NONIDLE (and similar), but rather push rcu_idle_enter|exit() further down, closer to the arch specific code. However, as the CPU PM notifiers are also using the RCU, additional rework is needed.

2020-09-21dax: Fix compilation for CONFIG_DAX && !CONFIG_FS_DAXJan Kara
dax_supported() is defined whenever CONFIG_DAX is enabled. So dummy implementation should be defined only in !CONFIG_DAX case, not in !CONFIG_FS_DAX case.

2020-09-21io_uring: fix openat/openat2 unified prep handlingJens Axboe
A previous commit unified how we handle prep for these two functions, but this means that we check the allowed context (SQPOLL, specifically) later than we should. Move the ring type checking into the two parent functions, instead of doing it after we've done some setup work.

2020-09-21io_uring: mark statx/files_update/epoll_ctl as non-SQPOLLJens Axboe
These will naturally fail when attempted through SQPOLL, but either with -EFAULT or -EBADF. Make it explicit that these are not workable through SQPOLL and return -EINVAL, just like other ops that need to use ->files. Signed-off-by: Jens Axboe <axboe@kernel.dk>

2020-09-21io_uring: don't use retry based buffered reads for non-async bdevJens Axboe
Some block devices, like dm, bubble back -EAGAIN through the completion handler. We check for this in io_read(), but don't honor it for when we have copied the iov. Return -EAGAIN for this case before retrying, to force punt to io-wq.

2020-09-21io_uring: don't re-setup vecs/iter in io_resumit_prep() is already thereJens Axboe
If we already have mapped the necessary data for retry, then don't set it up again. It's a pointless operation, and we leak the iovec if it's a large (non-stack) vec.
