      gpio: max732x: Add missing dev reference to gpiochip · 34ab54ed
      Marek Vasut 提交于
      In case the gpiochip doesn't have the .dev field set, as is the case
      in here, it is not possible to reference this device in DT as a GPIO
      controller. A good example of this problem is that gpio-leds can not
      be used when connected to this chip, the gpio-leds driver bails out
      with -EPROBE_DEFER.
      
      Fix this problem by setting the .dev field of the gpio_chip to the
      parent i2c device.

      gpio/xilinx: Use correct address when setting initial values. · 5b2c9121
      Raphaël Teysseyre 提交于
      xgpio_save_regs() is used in this driver to setup the initial
      values of the registers in the hardware.
      
      The relevant registers at that time are:
      0x0 -> channel 0 data (32 bits, one for each GPIO on this channel).
      0x4 -> channel 0 tri, controls in/out status for each GPIO of this channel.
      0x8 -> channel 1 data
      0xC -> channel 1 tri
      
      gpio-xilinx.c defines these:
      XGPIO_DATA_OFFSET   (0x0)
      XGPIO_TRI_OFFSET    (0x4)
      XGPIO_CHANNEL_OFFSET	0x8
      
      Before this patch, the "data" register value of channel 1 was written
      at 0x4 intead of 0x8 (overwriting the channel 0 "tri" register),
      and the "tri" register value for channel 1 was written at 0x8 instead of 0xC.
