+Subject: [PATCH] gpio: add a data pointer to gpio_chip
+
+This adds a void * pointer to gpio_chip so that driver can
+assign and retrieve some states. This is done to get rid of
+container_of() calls for gpio_chips embedded inside state
+containers, so we can remove the need to have the gpio_chip
+or later (planned) struct gpio_device be dynamically allocated
+at registration time, so that its struct device can be properly
+reference counted and not bound to its parent device (e.g.
+a platform_device) but instead live on after unregistration
+if it is opened by e.g. a char device or sysfs.
+
+The data is added with the new function gpiochip_add_data()
+and for compatibility we add static inline wrapper function
+gpiochip_add() that will call gpiochip_add_data() with
+NULL as argument. The latter will be removed once we have
+exorcised gpiochip_add() from the kernel.
+
+gpiochip_get_data() is added as a static inline accessor
+for drivers to quickly get their data out.

+Subject: [PATCH] gpio: generic: factor into gpio_chip struct
+
+The separate struct bgpio_chip has been a pain to handle, both
+by being confusingly similar in name to struct gpio_chip and
+for being contained inside a struct so that struct gpio_chip
+is contained in a struct contained in a struct, making several
+steps of dereferencing necessary.
+
+Make things simpler: include the fields directly into
+<linux/gpio/driver.h>, #ifdef:ed for CONFIG_GENERIC_GPIO, and
+get rid of the <linux/basic_mmio_gpio.h> altogether. Prefix
+some of the member variables with bgpio_* and add proper
+kerneldoc while we're at it.
+
+Modify all users to handle the change and use a struct
+gpio_chip directly. And while we're at it: replace all
+container_of() dereferencing by gpiochip_get_data() and
+registering the gpio_chip with gpiochip_add_data().
