This is the bulk of pin control changes for the v5.6 kernel cycle:

Browse Source 
Core changes:
 
 - Dropped the chained IRQ setup callback into GPIOLIB as we
   got rid of the last users of that in this changeset.
 
 New drivers:
 
 - New driver for Ingenic X1830.
 
 - New driver for Freescale i.MX8MP.
 
 Driver enhancements:
 
 - Fix all remaining Intel drivers to pass their IRQ chips
   along with the GPIO chips.
 
 - Intel Baytrail allocates its irqchip dynamically.
 
 - Intel Lynxpoint is thoroughly rewritten and modernized.
 
 - Aspeed AST2600 pin muxing and configuration is much
   improved.
 
 - Qualcomm SC7180 functions are updated and wakeup interrupt
   map is provided.
 
 - A whole slew of Renesas SH-PFC cleanups and improvements.
 
 - Fix up the Intel DT bindings to use the generic YAML
   DT bindings schema. (A first user of this.)

handler for a gpio_chip from a parent IRQ and passes the struct gpio_chip*

/*
* Lynxpoint gpios are controlled through both bitmapped registers and
* per gpio specific registers. The bitmapped registers are in chunks of
* 3 x 32bit registers to cover all 94 gpios
*
* per gpio specific registers consist of two 32bit registers per gpio
* (LP_CONFIG1 and LP_CONFIG2), with 94 gpios there's a total of
* 188 config registers.
*
* A simplified view of the register layout look like this:
*
* LP_ACPI_OWNED[31:0] gpio ownerships for gpios 0-31 (bitmapped registers)
* LP_ACPI_OWNED[63:32] gpio ownerships for gpios 32-63
* LP_ACPI_OWNED[94:64] gpio ownerships for gpios 63-94
* ...
* LP_INT_ENABLE[31:0] ...
* LP_INT_ENABLE[63:31] ...
* LP_INT_ENABLE[94:64] ...
* LP0_CONFIG1 (gpio 0) config1 reg for gpio 0 (per gpio registers)
* LP0_CONFIG2 (gpio 0) config2 reg for gpio 0
* LP1_CONFIG1 (gpio 1) config1 reg for gpio 1
* LP1_CONFIG2 (gpio 1) config2 reg for gpio 1
* LP2_CONFIG1 (gpio 2) ...
* LP2_CONFIG2 (gpio 2) ...
* ...
* LP94_CONFIG1 (gpio 94) ...
* LP94_CONFIG2 (gpio 94) ...
