* spi: imx: fix reference leak in two imx operationsZhang Qilong2020-11-101-0/+2
| | | | | | | | | | | | pm_runtime_get_sync will increment pm usage counter even it failed. Forgetting to pm_runtime_put_noidle will result in reference leak in callers(spi_imx_prepare_message and spi_imx_remove), so we should fix it.

* spi: atmel: Downgrade to dev_dbg when dma_request_chan() failsTudor Ambarus2020-10-301-3/+3
| | | | | | | | | | | | | | | | | | | | The IP's DMA capabilities are described in the SoC dtsi, to spare users duplicating the DMA bindings in their board device tree. Users that don't want to use DMA, have to overwrite the DMA bindings in their board device tree. An example is: commit ddcdaeb88242 ("ARM: dts: at91: sama5d2: Add DMA bindings for the SPI and UART flx4 functions") When the DMA bindings are overwritten, one could see on the console: atmel_spi fc018400.spi: error -ENODEV: No TX DMA channel, DMA is disabled atmel_spi fc018400.spi: Atmel SPI Controller using PIO only Choosing to not use DMA is not a reason to print an error message. More, the user is already informed when PIO is used: "Atmel SPI Controller using PIO only". Downgrade to dev_dbg when dma_request_chan() fails.

* spi: spi-sun6i: enable autosuspend featureAlexander Kochetkov2020-10-271-1/+4
| | | | | | | | | | | | | | | | If SPI is used for periodic polling any sensor, significant delays sometimes appear. Switching on module clocks during resume lead to delays. Enabling autosuspend mode causes the controller to not suspend between SPI transfers and the delays disappear. The commit also remove unnecessary call to pm_runtime_idle() used to explicit put device to suspended state. Without pm_runtime_idle() PM core will put device in the suspended state just after probe() returns.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 525c9e5a32bd introduced pm_runtime support for the i.MX SPI driver. With this pm_runtime is used to bring up the clocks initially. When CONFIG_PM is disabled the clocks are no longer enabled and the driver doesn't work anymore. Fix this by enabling the clocks in the probe function and telling pm_runtime that the device is active using pm_runtime_set_active().

But i2c_acpi_install_space_handler() had a call to acpi_walk_dep_device_list() hidden (that is I missed it) at the end of it, so as an unwanted side-effect now acpi_walk_dep_device_list() was also being called before i2c_acpi_register_devices(). Move the acpi_walk_dep_device_list() call to the end of i2c_acpi_register_devices(), so that it is once again called *after* the i2c_client-s hanging of the adapter have been created.

This change broke some existing userspace code (e.g. udevadm, systemd-udevd, elogind) which called specific syscalls which do strict value checking on their flag parameter. This patch adds wrapper functions for the relevant syscalls. The wrappers masks out any old invalid O_NONBLOCK flags, reports in the syslog if the old O_NONBLOCK value was used and then calls the target syscall with the new O_NONBLOCK value.

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.
