14 * This driver is a fairly straightforward GPIO driver for the
15 * complete family of Marvell EBU SoC platforms (Orion, Dove,
16 * Kirkwood, Discovery, Armada 370/XP). The only complexity of this
17 * driver is the different register layout that exists between the
18 * non-SMP platforms (Orion, Dove, Kirkwood, Armada 370) and the SMP
19 * platforms (MV78200 from the Discovery family and the Armada
20 * XP). Therefore, this driver handles three variants of the GPIO
21 * block:
22 * - the basic variant, called "orion-gpio", with the simplest
23 * register set. Used on Orion, Dove, Kirkwoord, Armada 370 and
24 * non-SMP Discovery systems
25 * - the mv78200 variant for MV78200 Discovery systems. This variant
26 * turns the edge mask and level mask registers into CPU0 edge
27 * mask/level mask registers, and adds CPU1 edge mask/level mask
28 * registers.
29 * - the armadaxp variant for Armada XP systems. This variant keeps
30 * the normal cause/edge mask/level mask registers when the global
31 * interrupts are used, but adds per-CPU cause/edge mask/level mask
32 * registers n a separate memory area for the per-CPU GPIO
33 * interrupts.

15 * Quirk 1: Shortcut interrupts don't set the bank 1/2 register pending bits
16 *
17 * If an interrupt fires on bank 1 that isn't in the shortcuts list, bit 8
18 * on bank 0 is set to signify that an interrupt in bank 1 has fired, and
19 * to look in the bank 1 status register for more information.
20 *
21 * If an interrupt fires on bank 1 that _is_ in the shortcuts list, its
22 * shortcut bit in bank 0 is set as well as its interrupt bit in the bank 1
23 * status register, but bank 0 bit 8 is _not_ set.
24 *
25 * Quirk 2: You can't mask the register 1/2 pending interrupts
26 *
27 * In a proper cascaded interrupt controller, the interrupt lines with
28 * cascaded interrupt controllers on them are just normal interrupt lines.
29 * You can mask the interrupts and get on with things. With this controller
30 * you can't do that.
31 *
32 * Quirk 3: The shortcut interrupts can't be (un)masked in bank 0
33 *
34 * Those interrupts that have shortcuts can only be masked/unmasked in
35 * their respective banks' enable/disable registers. Doing so in the bank 0
36 * enable/disable registers has no effect.
37 *
38 * The FIQ control register:
39 * Bits 0-6: IRQ (index in order of interrupts from banks 1, 2, then 0)
40 * Bit 7: Enable FIQ generation
41 * Bits 8+: Unused
42 *
43 * An interrupt must be disabled before configuring it for FIQ generation
44 * otherwise both handlers will fire at the same time!

13 * This file supports the three variants of Armada XP SoCs that are
14 * available: mv78230, mv78260 and mv78460. From a pin muxing
15 * perspective, the mv78230 has 49 MPP pins. The mv78260 and mv78460
16 * both have 67 MPP pins (more GPIOs and address lines for the memory
17 * bus mainly). The only difference between the mv78260 and the
18 * mv78460 in terms of pin muxing is the addition of two functions on
19 * pins 43 and 56 to access the VDD of the CPU2 and 3 (mv78260 has two
20 * cores, mv78460 has four cores).

16/**
17 * struct mvebu_mpp_ctrl - describe a mpp control
18 * @name: name of the control group
19 * @pid: first pin id handled by this control
20 * @npins: number of pins controlled by this control
21 * @mpp_get: (optional) special function to get mpp setting
22 * @mpp_set: (optional) special function to set mpp setting
23 * @mpp_gpio_req: (optional) special function to request gpio
24 * @mpp_gpio_dir: (optional) special function to set gpio direction
25 *
26 * A mpp_ctrl describes a muxable unit, e.g. pin, group of pins, or
27 * internal function, inside the SoC. Each muxable unit can be switched
28 * between two or more different settings, e.g. assign mpp pin 13 to
29 * uart1 or sata.
30 *
31 * If optional mpp_get/_set functions are set these are used to get/set
32 * a specific mode. Otherwise it is assumed that the mpp control is based
33 * on 4-bit groups in subsequent registers. The optional mpp_gpio_req/_dir
34 * functions can be used to allow pin settings with varying gpio pins.
