6 -GPIOMMC - Driver for an MMC/SD card on a bitbanging GPIO SPI bus
7 -================================================================
8 -
9 -The gpiommc module hooks up the mmc_spi and spi_gpio modules for running an
10 -MMC or SD card on GPIO pins.
11 -
12 -Two interfaces for registering a new MMC/SD card device are provided:
13 -A static platform-device based mechanism and a dynamic configfs based interface.
14 -
15 -
16 -Registering devices via platform-device
17 -=======================================
18 -
19 -The platform-device interface is used for registering MMC/SD devices that are
20 -part of the hardware platform. This is most useful only for embedded machines
21 -with MMC/SD devices statically connected to the platform GPIO bus.
22 -
23 -The data structures are declared in <linux/mmc/gpiommc.h>.
24 -
25 -To register a new device, define an instance of struct gpiommc_platform_data.
26 -This structure holds any information about how the device is hooked up to the
27 -GPIO pins and what hardware modes the device supports. See the docbook-style
28 -documentation in the header file for more information on the struct fields.
29 -
30 -Then allocate a new instance of a platform device by doing:
31 -
32 - pdev = platform_device_alloc(GPIOMMC_PLATDEV_NAME, gpiommc_next_id());
33 -
34 -This will allocate the platform device data structures and hook it up to the
35 -gpiommc driver.
36 -Then add the gpiommc_platform_data to the platform device.
37 -
38 - err = platform_device_add_data(pdev, pdata, sizeof(struct gpiommc_platform_data));
39 -
40 -You may free the local instance of struct gpiommc_platform_data now. (So the
41 -struct may be allocated on the stack, too).
42 -Now simply register the platform device.
43 -
44 - err = platform_device_add(pdev);
45 -
46 -Done. The gpiommc probe routine will be invoked now and you should see a kernel
47 -log message for the added device.
48 -
49 -
50 -Registering devices via configfs
51 -================================
52 -
53 -MMC/SD cards connected via GPIO often are a pretty dynamic thing, as for example
54 -selfmade hacks for soldering an MMC/SD card to standard GPIO pins on embedded
55 -hardware are a common situation.
56 -So we provide a dynamic interface to conveniently handle adding and removing
57 -devices from userspace, without the need to recompile the kernel.
58 -
59 -The "gpiommc" subdirectory at the configfs mountpoint is used for handling
60 -the dynamic configuration.
61 -
62 -To create a new device, it must first be allocated with mkdir.
63 -The following command will allocate a device named "my_mmc":
64 - mkdir /config/gpiommc/my_mmc
65 -
66 -There are several configuration files available in the new
67 -/config/gpiommc/my_mmc/ directory:
68 -
69 -gpio_data_in = The SPI data-IN GPIO pin number.
70 -gpio_data_out = The SPI data-OUT GPIO pin number.
71 -gpio_clock = The SPI Clock GPIO pin number.
72 -gpio_chipselect = The SPI Chipselect GPIO pin number.
73 -gpio_chipselect_activelow = Boolean. If 0, Chipselect is active-HIGH.
74 - If 1, Chipselect is active-LOW.
75 -spi_mode = The SPI data mode. Can be 0-3.
76 -spi_delay = Enable all delays in the lowlevel bitbanging.
77 -max_bus_speed = The maximum SPI bus speed. In Hertz.
78 -
79 -register = Not a configuration parameter.
80 - Used to register the configured card
81 - with the kernel.
82 -
83 -The device must first get configured and then registered by writing "1" to
84 -the "register" file.
85 -The configuration parameters "gpio_data_in", "gpio_data_out", "gpio_clock"
86 -and "gpio_chipselect" are essential and _must_ be configured before writing
87 -"1" to the "register" file. The registration will fail, otherwise.
88 -
89 -The default values for the other parameters are:
90 -gpio_chipselect_activelow = 1 (CS active-LOW)
91 -spi_mode = 0 (SPI_MODE_0)
92 -spi_delay = 1 (enabled)
93 -max_bus_speed = 5000000 (5 Mhz)
94 -
95 -Configuration values can not be changed after registration. To unregister
96 -the device, write a "0" to the "register" file. The configuration can be
97 -changed again after unregistering.
98 -
99 -To completely remove the device, simply rmdir the directory
100 -(/config/gpiommc/my_mmc in this example).
101 -There's no need to first unregister the device before removing it. That will
102 -be done automatically.
