Subject: [2/5] mmc: mvsdio: use slot-gpio infrastructure for write protect gpio
Date: Wed, 16 Jan 2013 13:13:57 -0000
From: Andrew Lunn <andrew@lunn.ch>

Message-Id: <1358342040-7130-3-git-send-email-andrew@lunn.ch>

Andrew Lunn <andrew@lunn.ch>
From: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
The MMC core subsystem provides in drivers/mmc/core/slot-gpio.c a nice
set of helper functions to simplify the management of the write
protect GPIO in MMC host drivers. This patch migrates the mvsdio
driver to using those helpers, which will make the ->probe() code
simpler, and therefore ease the process of adding a Device Tree
binding for this driver.

From: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
This patch adds a simple Device Tree binding for the mvsdio driver, as
well as the necessary documentation for it. Compatibility with non-DT
platforms is preserved, by keeping the platform_data based
initialization.
We introduce a small difference between non-DT and DT platforms: DT
platforms are required to provide a clocks = <...> property, which the
driver uses to get the frequency of the clock that goes to the SDIO
IP. The behaviour on non-DT platforms is kept unchanged: a clock
reference is not mandatory, but the clock frequency must be passed in
the "clock" field of the mvsdio_platform_data structure.

From: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
On many Marvell SoCs, the pins used for the SDIO interface are part of
the MPP pins, that are muxable pins. In order to get the muxing of
those pins correct, this commit integrates the mvsdio driver with the
pinctrl infrastructure by calling devm_pinctrl_get_select_default()
during ->probe().
Note that we permit this function to fail because not all Marvell
platforms have yet been fully converted to using the pinctrl
infrastructure.

The SDIO interface is available either on pins MPP9/11/12/13/14/15 or
MPP47/48/49/50/51/52 on the Armada 370. Even though all combinations
are potentially possible, those two muxing options are the most
probable ones, so we provide those at the SoC level .dtsi file.
In practice, in turns out the Armada 370 DB board uses the former,
while the Armada 370 Mirabox uses the latter.

The SDIO interface is only available on pins MPP30/31/32/33/34/35 on
the various Armada XP variants, so we provide a pin muxing option for
this in the Armada XP .dtsi files.
Even though those muxing options are the same for MV78230, MV78260 and
MV78460, we keep them in each .dtsi file, because the number of pins,
and therefore the declaration of the pinctrl node, is different for
each SoC variant.

The Armada XP DB evaluation board has one SD card slot, directly
connected to the SDIO IP of the SoC, so we add a device tree
description for it.
However, in the default configuration of the board, the SD card slot
is not usable: the connector plugged into CON40 must be changed
against a different one, provided with the board by the
manufacturer. Since such a manual modification of the hardware is
needed, we did not enable the SDIO interface by default, and left it
to the board user to modify the Device Tree if needed. Since this
board is really only an evaluation board for developers and not a
final product, it is not too bad.

This patch adds the DTS file to support the Marvell RD-A370-A1

entirely similar to the DB-A370 board except that the first Ethernet PHY
is SGMII-wired and the second is a switch which is RGMII-wired.

The Armada 370 has two gatable clocks for each PCIe interface, and we
want both of them to be enabled. We therefore make one of the two
clocks a child of the other, as we did for the sataX and sataXlnk

In the address decoding code, the orion_disable_wins() function is
used at boot time to disable all address decoding windows, before
configuring only the ones that are needed. This allows to make sure
that no configuration is left from the bootloader.
As a preparation for the introduction of address decoding window
allocation/deallocation function, we refactor this function into an
orion_disable_cpu_win() which disables a single window.
The orion_config_wins() function is changed to call
orion_disable_cpu_win() in a loop, to preserve an identical behavior.

In the address decoding code, we implement two new functions:
orion_alloc_cpu_win() and orion_free_cpu_win(). The first function
finds an unused address decoding window, and configures it according
to the given arguments (in terms of base address, size, target,
attributes). The second function frees an address decoding window,
given a physical base address.
Those two new functions will be used by the PCIe code, which needs to
dynamically register address decoding windows depending on the PCIe
devices that are detected.
The orion_free_cpu_win() function is only here to handle error cases
in the PCIe devices initialization, in the normal case, address
decoding windows are never freed.

This commit adds two functions armada_370_xp_alloc_pcie_window() and
armada_370_xp_free_pcie_window() that respectively allocate and free
an address decoding window pointing to either a memory or I/O region
of a PCIe device.
Those functions will be used by the PCIe driver to create and remove
those regions depending on the PCIe devices that are detected.

mvebu is a new-style Orion platform, so it only selects PLAT_ORION,
but not PLAT_ORION_LEGACY. It will however need the common PCIe code
from plat-orion, so make this code available for PLAT_ORION platforms
as a whole, and not only PLAT_ORION_LEGACY platforms.
We also take this opportunity to build the PCIe code only when

This driver implements the hw_pci operations needed by the core ARM
PCI code to setup PCI devices and get their corresponding IRQs, and
the pci_ops operations that are used by the PCI core to read/write the
configuration space of PCI devices.
In addition, this driver enumerates the different PCIe slots, and for
those having a device plugged in, it allocates the necessary address
decoding windows, using the new armada_370_xp_alloc_pcie_window()
function from mach-mvebu/addr-map.c.

The Armada XP SoCs have multiple PCIe interfaces. The MV78230 has 2
PCIe units (one 4x or quad 1x, the other 1x only), the MV78260 has 3
PCIe units (two 4x or quad 1x and one 4x/1x), the MV78460 has 4 PCIe
units (two 4x or quad 1x and two 4x/1x). We therefore add the
necessary Device Tree informations to make those PCIe interfaces
usable.

The PlatHome OpenBlocks AX3-4 has an internal mini-PCIe slot that can
be used to plug mini-PCIe devices. We therefore enable the PCIe
interface that corresponds to this slot.
