2022-01-06serial: stm32: rework TX DMA state conditionValentin Caron
TX DMA state condition is handled by tx_dma_busy boolean. This boolean is set when dma descriptor is requested and reset when dma channel is stopped (dma_terminate). In stm32_usart_serial_remove(), stm32_usart_stop_tx() and stm32_usart_transmit_chars_dma() fallback error case, DMA channel is stopped but tx_dma_busy is not handled. Rework the driver by using two new functions to solve this issue: - stm32_usart_tx_dma_started return true if DMA TX have a descriptor. - stm32_usart_tx_dma_enabled return true if DMAT bit is set. stm32_usart_tx_dma_started uses tx_dma_busy flag to prevent dual DMA transaction at the same time. This flag is set when a DMA transaction begins and is unset when dmaengine_terminate_async function is called. A new DMA transaction cannot be created if this flag is set. Create a new function "stm32_usart_tx_dma_terminate" to be sure the flag is unset after each call of dmaengine_terminate_async.

2022-01-06serial: stm32: move tx dma terminate DMA to shutdownValentin Caron
Terminate DMA transaction and clear CR3_DMAT when shutdown is requested, instead of when remove is requested. If DMA transfer is not stopped in shutdown ops, driver will fail to start a new DMA transfer after next startup ops.

2022-01-06serial: pl011: Drop redundant DTR/RTS preservation on close/openLukas Wunner
Commit d8d8ffa47783 ("amba-pl011: do not disable RTS during shutdown") amended the PL011 serial driver to leave DTR/RTS polarity untouched on tty close. That change made sense. But the commit also added code to save DTR/RTS state to an internal variable on tty close and restore it on tty open. That part of the commit makes less sense: The driver has no ->pm() callback, so the uart remains powered after tty close and automatically preserves register state, including DTR/RTS. Saving and restoring registers isn't the job of the ->startup() and ->shutdown() callbacks anyway. Rather, it should happen in ->pm(). Additionally, after pl011_startup() restores the state, the serial core overrides it in uart_port_dtr_rts() if a baud rate has been set: tty_port_open() uart_port_activate() uart_startup() uart_port_startup() pl011_startup() # restores DTR/RTS from uap->old_cr tty_port_block_til_ready() tty_port_raise_dtr_rts # if (C_BAUD(tty)) uart_dtr_rts() uart_port_dtr_rts() # raises DTR/RTS The serial core also overrides DTR/RTS on tty close in uart_shutdown() if C_HUPCL(tty) is set. So a user-defined DTR/RTS polarity won't survive a close/open cycle anyway, unless the user has set the baud rate to zero and disabled hupcl on the tty. Bottom line is, the code to save and restore DTR/RTS has no effect. Remove it.

2022-01-06serial: pl011: Drop CR register reset on set_termiosLukas Wunner
pl011_set_termios() briefly resets the CR register to zero, thereby glitching DTR/RTS signals. With rs485 this may result in the bus being occupied for no reason. Where does this register write originate from? The PL011 driver was forked from the PL010 driver in 2004: https://git.kernel.org/history/history/c/157c0342e591 Until this commit, the PL010 driver's IRQ handler ambauart_int() modified the CR register without holding the port spinlock. ambauart_set_termios() also modified that register. To prevent concurrent read-modify-writes by the IRQ handler and to prevent transmission while changing baudrate, ambauart_set_termios() had to disable interrupts. On the PL010, that is achieved by writing zero to the CR register. However, on the PL011, interrupts are disabled in the IMSC register, not in the CR register. Additionally, the commit amended both the PL010 and PL011 driver to acquire the port spinlock in the IRQ handler, obviating the need to disable interrupts in ->set_termios(). So the CR register write is obsolete for two reasons. Drop it.

2022-01-06counter: 104-quad-8: Fix use-after-free by quad8_irq_handlerWilliam Breathitt Gray
On unbind an irq might be pending which results in quad8_irq_handler() calling counter_push_event() for a counter that is already unregistered. This patch fixes that situation by passing the struct counter_device dev to devm_request_irq() rather than the parent's so that the irq handler is cleaned before the counter is unregistered.

If bInterval is 1, then p_interval is 8000 and p_interval_mil is 8E9, which is too big for a 32-bit value. While the storage is indeed 64-bit, this value is used as the divisor in do_div() which will truncate it into a uint32_t leading to incorrect calculated values.

But after that commit params.speed is updated based on a value passed in by the gadget core which may set it to a faster speed than is supported by the hardware.

2022-01-06regulator: qcom_smd: Align probe function with rpmh-regulatorKonrad Dybcio
The RPMh regulator driver is much newer and gets more attention, which in consequence makes it do a few things better. Update qcom_smd-regulator's probe function to mimic what rpmh-regulator does to address a couple of issues: - Probe defer now works correctly, before it used to, well, kinda just die.. This fixes reliable probing on (at least) PM8994, because Linux apparently cannot deal with supply map dependencies yet.. - Regulator data is now matched more sanely: regulator data is matched against each individual regulator node name and throwing an -EINVAL if data is missing, instead of just assuming everything is fine and iterating over all subsequent array members. - status = "disabled" will now work for disabling individual regulators in DT. Previously it didn't seem to do much if anything at all.

2022-01-06ASoC: fsl_asrc: refine the check of available clock dividerShengjiu Wang
According to RM, the clock divider range is from 1 to 8, clock prescaling ratio may be any power of 2 from 1 to 128. So the supported divider is not all the value between 1 and 1024, just limited value in that range. Create table for the supported divder and add function to check the clock divider is available by comparing with the table.

2022-01-06ASoC: Intel: bytcr_rt5640: Add support for external GPIO jack-detectHans de Goede
Some boards have the codec IRQ hooked-up as normally, so the driver can still do things like headset vs headphones and button-press detection, but instead of using one of the JD pins of the codec, an external GPIO is used to report the jack-presence switch status of the jack. Add support for boards which have this setup and which specify which external GPIO to use in the special Android AMCR0F28 ACPI device. And add a quirk for the Asus TF103C tablet which uses this setup.

AMCR0F28 ACPI dev Some X86 tablets, which ship with Android as factory installed OS, specify codec IRQs/GPIOS in a special Android AMCR0F28 ACPI device. Add support for retrieving the codec IRQ from this ACPI device instead of from the 10EC5640 device describing the codec itself and enable this on Asus MemoPad 7 ME176C tablets. This fixes jack-detect not working on these tablets.

2022-01-06ASoC: rt5640: Allow snd_soc_component_set_jack() to override the codec IRQHans de Goede
On some boards where the firmware/fwnode information is in essence read-only (x86 + ACPI boards) the i2c_client for the codec may contain the wrong IRQ or no IRQ at all. Since we only request the IRQ once snd_soc_component_set_jack() gets called, allow machine drivers to override the IRQ with the proper one through the data parameter to snd_soc_component_set_jack().

2022-01-06ASoC: rt5640: Fix possible NULL pointer deref on resumeHans de Goede
Commit 2b9c8d2b3c89 ("ASoC: rt5640: Add the HDA header support") adds re-queuing of the jack_work on resume when rt5640->jd_src != 0. But the jack_work will unconditionally deref rt5640->jack and that might be NULL. E.g. the sound/soc/intel/boards/bytcr_rt5640.c machine driver call snd_soc_component_set_jack(codec, NULL, NULL) from pre_suspend to disable the IRQ to avoid spurious wakeups, so when rt5640_resume() runs rt5640->jack will be NULL in this case. Make the queueing of the work conditional on rt5640->jack instead of on rt5640->jd_src to fix this.
