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.

The MMC core subsystem provides in drivers/mmc/core/slot-gpio.c a nice
|
|
||||||
set of helper functions to simplify the management of the card detect
|
|
||||||
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.

|
|
||||||
|
|
||||||
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.

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.

Subject: [PATCH] arm: mvebu: add DTS file for Marvell RD-A370-A1 board
|
|
||||||
|
|
||||||
This patch adds the DTS file to support the Marvell RD-A370-A1
|
|
||||||
(Reference Design board) also known as RD-88F6710 board. It is almost
|
|
||||||
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.

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
|
|
||||||
CONFIG_PCI is enabled.

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.

+* Marvell Armada 370/XP PCIe interfaces
|
|
||||||
+
|
|
||||||
+Mandatory properties:
|
|
||||||
+- compatible: must be "marvell,armada-370-xp-pcie"
|
|
||||||
+- status: either "disabled" or "okay"
|
|
||||||
+- #address-cells, set to <1>
|
|
||||||
+- #size-cells, set to <1>
|
|
||||||
+- ranges: describes the association between the physical addresses of
|
|
||||||
+ the PCIe registers for each PCIe interface with "virtual" addresses
|
|
||||||
+ as seen by the sub-nodes. One entry per PCIe interface. Each entry
|
|
||||||
+ must have 3 values: the "virtual" address seen by the sub-nodes, the
|
|
||||||
+ real physical address of the PCIe registers, and the size.
|
|
||||||
+
|
|
||||||
+In addition, the Device Tree node must have sub-nodes describing each
|
|
||||||
+PCIe interface, having the following mandatory properties:
|
|
||||||
+- reg: the address and size of the PCIe registers (translated
|
|
||||||
+ addresses according to the ranges property of the parent)
|
|
||||||
+- interrupts: the interrupt number of this PCIe interface
|
|
||||||
+- clocks: the clock associated to this PCIe interface
|
|
||||||
+- marvell,pcie-port: the physical PCIe port number
|
|
||||||
+- status: either "disabled" or "okay"
|
|
||||||
+
|
|
||||||
+and the following optional properties:
|
|
||||||
+- marvell,pcie-lane: the physical PCIe lane number, for ports having
|
|
||||||
+ multiple lanes. If this property is not found, we assume that the
|
|
||||||
+ value is 0.

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.
