      spi: gpio: Add SPI_MASTER_GPIO_SS flag · 2922d1cc
      Linus Walleij authored
      The GPIO SPI master has some code in its local CS
      callback to set the initial sck GPIO value. This was
      lost in the commit converting it to use SPI core
      GPIO handling as this callback isn't called if the
      internal GPIO handling is active.
      Add the special SPI_MASTER_GPIO_SS to ascertain it
      gets called anyway so we get the initial SCK setting
      right. There is some platform provided GPIO handling
      there as well but this will be skipped as the cs_gpios
      will be NULL.
      My test targets seem not to care about the initial
      SCK value so I am uncertain if this is a regression,
      but to preserve the previous semantic we better do

      spi/acpi: fix incorrect ACPI parent check · b5e3cf41
      Ard Biesheuvel authored
      The ACPI device object parsing code for SPI slaves enumerates the
      entire ACPI namespace to look for devices that refer to the master
      in question via the 'resource_source' field in the 'SPISerialBus'
      resource. If that field does not refer to a valid ACPI device or
      if it refers to the wrong SPI master, we should disregard the
      Current, the valid device check is wrong, since it gets the
      polarity of 'status' wrong. This could cause issues if the
      'resource_source' field is bogus but parent_handle happens to
      refer to the correct master (which is not entirely imaginary
      since this code runs in a loop)
      So test for ACPI_FAILURE() instead, to make the code more
      self explanatory.

      spi/acpi: enumerate all SPI slaves in the namespace · 4c3c5954
      Ard Biesheuvel authored
      Currently, the ACPI enumeration that takes place when registering a
      SPI master only considers immediate child devices in the ACPI namespace,
      rather than checking the ResourceSource field in the SpiSerialBus()
      resource descriptor.
      This is incorrect: SPI slaves could reside anywhere in the ACPI
      namespace, and so we should enumerate the entire namespace and look for
      any device that refers to the newly registered SPI master in its
      resource descriptor.
      So refactor the existing code and use a lookup structure so that
      allocating the SPI device structure is deferred until we have identified
      the device as an actual child of the controller. This approach is
      loosely based on the way the I2C subsystem handles ACPI enumeration.
      Note that Apple x86 hardware does not rely on SpiSerialBus() resources
      in _CRS but uses nested devices below the controller's device node in
      the ACPI namespace, with a special set of device properties. This means
      we have to take care to only parse those properties for device nodes
      that are direct children of the controller node.

      spi: Use struct_size() helper · aef97522
      Gustavo A. R. Silva authored
      One of the more common cases of allocation size calculations is finding
      the size of a structure that has a zero-sized array at the end, along
      with memory for some number of elements for that array. For example:
      struct spi_replaced_transfers {
              struct spi_transfer inserted_transfers[];
      Make use of the struct_size() helper instead of an open-coded version
      in order to avoid any potential type mistakes.
      So, replace the following form:
      insert * sizeof(struct spi_transfer) + sizeof(struct spi_replaced_transfers)
      struct_size(rxfer, inserted_transfers, insert)
      This code was detected with the help of Coccinelle.
