      gpio: tps6586x: make explicitly non-modular · a0e63738
      Paul Gortmaker authored
      The Kconfig currently controlling compilation of this code is:
      
      drivers/gpio/Kconfig:config GPIO_TPS6586X
      drivers/gpio/Kconfig:   bool "TPS6586X GPIO"
      
      ...meaning that it currently is not being built as a module by anyone.
      
      Lets remove the modular code that is essentially orphaned, so that
      when reading the driver there is no doubt it is builtin-only.
      
      Since module_init was not in use by this code, the init ordering
      remains unchanged with this commit.
      
      We also delete the MODULE_LICENSE tag etc. since all that information
      is already contained at the top of the file in the comments.

      gpio: tc3589x: implement open drain/source callback · 8b866b06
      Linus Walleij authored
      This makes use of the new .set_single_ended() callback to
      set the GPIO line as open drain/open source using hardware.
      The TC3589x can do this by either disabling the N-MOS
      transistor (open drain) or the P-MOS transistor (open source)
      of the output driver stage, in the first case making the signal
      drive actively low and high impedance as "high" and in the second
      case actively high and high impedance, which is as close to native
      open drain support as we come.

      gpio: tc3589x: use BIT() macro · cee1b40d
      Linus Walleij authored
      This switch to use BIT(n) instead of (1 << n) which is less
      to the point. Most GPIO drivers do this to avoid mistakes.
      Also switch from using <linux/gpio.h> to the apropriate
      <linux/gpio/driver.h> include.

      gpio: support native single-ended hardware drivers · c663e5f5
      Linus Walleij authored
      Some GPIO controllers has a special hardware bit we can flip
      to support open drain / source. This means that on these hardwares
      we do not need to emulate OD/OS by setting the line to input
      instead of actively driving it high/low. Add an optional vtable
      callback to the driver set_single_ended() so that driver can
      implement this in hardware if they have it.
      
      We may need a pinctrl_gpio_set_config() call at some point to
      propagate this down to a backing pin control device on systems
      with split GPIO/pin control.
