• 91f1551a7   gpio: ts4800: Fix module autoload ... Browse Code »

  If the driver is built as a module, autoload won't work because the module
  alias information is not filled. So user-space can't match the registered
  device with the corresponding module.

  Export the module alias information using the MODULE_DEVICE_TABLE() macro.

  Before this patch:

  $ modinfo drivers/gpio/gpio-ts4800.ko | grep alias
  $

  After this patch:

  $ modinfo drivers/gpio/gpio-ts4800.ko | grep alias
  alias: of:N*T*Ctechnologic,ts4800-gpioC*
  alias: of:N*T*Ctechnologic,ts4800-gpio

• 7de9a6c75   gpio: ts4800: fix implicit assumption module.h is present ... Browse Code »

  The Kconfig for this file is:

  drivers/gpio/Kconfig:config GPIO_TS4800
  drivers/gpio/Kconfig: tristate "TS-4800 DIO blocks and compatibles"

  ...but however it does not include module.h -- it in turn gets it from
  another header (gpio/driver.h) and we'd like to replace that with a
  forward delcaration of "struct module;" but if we do, this file will
  fail to compile.

  So we fix this first to avoid putting build failures into the bisect
  commit history.

  No flags are required for bgpio_init in the TS-4800 gpio driver. This
  patch set zero instead. The driver will have the same behaviour since
  the & operator between the flags already resulted to zero.

  The TS-4800 GPIO driver provide support for the GPIOs available
  on the Technologic Sytems board FPGA. It allows to set
  direction and read/write states.

  It uses the generic gpio driver.
