on the setup, so I think that the choice on what firmware to make
persistent should be left to userspace.
- Why register_firmware()+__init can be useful:
- For boot devices needing firmware.
- To make the transition easier:
The firmware can be declared __init and register_firmware()
called on module_init. Then the firmware is warranted to be
there even if "firmware hotplug userspace" is not there yet or
it doesn't yet provide the needed firmware.
Once the firmware is widely available in userspace, it can be
removed from the kernel. Or made optional (CONFIG_.*_FIRMWARE).
In either case, if firmware hotplug support is there, it can move the
firmware out of kernel memory into the real filesystem for later
usage.
Note: If persistence is implemented on top of initramfs,
register_firmware() may not be appropriate.

PXA2xx SPI on SSP driver HOWTO
===================================================
This a mini howto on the pxa2xx_spi driver. The driver turns a PXA2xx
synchronous serial port into a SPI master controller
(see Documentation/spi/spi_summary). The driver has the following features
- Support for any PXA2xx SSP
- SSP PIO and SSP DMA data transfers.
- External and Internal (SSPFRM) chip selects.
- Per slave device (chip) configuration.
- Full suspend, freeze, resume support.
The driver is built around a "spi_message" fifo serviced by workqueue and a
tasklet. The workqueue, "pump_messages", drives message fifo and the tasklet
(pump_transfer) is responsible for queuing SPI transactions and setting up and
launching the dma/interrupt driven transfers.
Declaring PXA2xx Master Controllers
-----------------------------------
Typically a SPI master is defined in the arch/.../mach-*/board-*.c as a
"platform device". The master configuration is passed to the driver via a table
found in include/asm-arm/arch-pxa/pxa2xx_spi.h:
struct pxa2xx_spi_master {
enum pxa_ssp_type ssp_type;
u32 clock_enable;
u16 num_chipselect;
u8 enable_dma;
};
The "pxa2xx_spi_master.ssp_type" field must have a value between 1 and 3 and
informs the driver which features a particular SSP supports.
The "pxa2xx_spi_master.clock_enable" field is used to enable/disable the
corresponding SSP peripheral block in the "Clock Enable Register (CKEN"). See
the "PXA2xx Developer Manual" section "Clocks and Power Management".
The "pxa2xx_spi_master.num_chipselect" field is used to determine the number of
slave device (chips) attached to this SPI master.
The "pxa2xx_spi_master.enable_dma" field informs the driver that SSP DMA should
be used. This caused the driver to acquire two DMA channels: rx_channel and
tx_channel. The rx_channel has a higher DMA service priority the tx_channel.
See the "PXA2xx Developer Manual" section "DMA Controller".
NSSP MASTER SAMPLE
------------------
Below is a sample configuration using the PXA255 NSSP.
static struct resource pxa_spi_nssp_resources[] = {
[0] = {
.start = __PREG(SSCR0_P(2)), /* Start address of NSSP */
.end = __PREG(SSCR0_P(2)) + 0x2c, /* Range of registers */
.flags = IORESOURCE_MEM,
},
[1] = {
.start = IRQ_NSSP, /* NSSP IRQ */
.end = IRQ_NSSP,
.flags = IORESOURCE_IRQ,
},
};
static struct pxa2xx_spi_master pxa_nssp_master_info = {
.ssp_type = PXA25x_NSSP, /* Type of SSP */
.clock_enable = CKEN9_NSSP, /* NSSP Peripheral clock */
.num_chipselect = 1, /* Matches the number of chips attached to NSSP */
.enable_dma = 1, /* Enables NSSP DMA */
};
static struct platform_device pxa_spi_nssp = {
.name = "pxa2xx-spi", /* MUST BE THIS VALUE, so device match driver */
.id = 2, /* Bus number, MUST MATCH SSP number 1..n */
.resource = pxa_spi_nssp_resources,
.num_resources = ARRAY_SIZE(pxa_spi_nssp_resources),
.dev = {
.platform_data = &pxa_nssp_master_info, /* Passed to driver */
},
};
static struct platform_device *devices[] __initdata = {
&pxa_spi_nssp,
};
static void __init board_init(void)
{
(void)platform_add_device(devices, ARRAY_SIZE(devices));
}
Declaring Slave Devices
-----------------------
Typically each SPI slave (chip) is defined in the arch/.../mach-*/board-*.c
using the "spi_board_info" structure found in "linux/spi/spi.h". See
"Documentation/spi/spi_summary" for additional information.
Each slave device attached to the PXA must provide slave specific configuration
information via the structure "pxa2xx_spi_chip" found in
"include/asm-arm/arch-pxa/pxa2xx_spi.h". The pxa2xx_spi master controller driver
will uses the configuration whenever the driver communicates with the slave
device.
struct pxa2xx_spi_chip {
u8 tx_threshold;
u8 rx_threshold;
u8 dma_burst_size;
u32 timeout_microsecs;
u8 enable_loopback;
void (*cs_control)(u32 command);
};
The "pxa2xx_spi_chip.tx_threshold" and "pxa2xx_spi_chip.rx_threshold" fields are
used to configure the SSP hardware fifo. These fields are critical to the
performance of pxa2xx_spi driver and misconfiguration will result in rx
fifo overruns (especially in PIO mode transfers). Good default values are
.tx_threshold = 12,
.rx_threshold = 4,
The "pxa2xx_spi_chip.dma_burst_size" field is used to configure PXA2xx DMA
engine and is related the "spi_device.bits_per_word" field. Read and understand
the PXA2xx "Developer Manual" sections on the DMA controller and SSP Controllers
to determine the correct value. An SSP configured for byte-wide transfers would
use a value of 8.
The "pxa2xx_spi_chip.timeout_microsecs" fields is used to efficiently handle
trailing bytes in the SSP receiver fifo. The correct value for this field is
dependent on the SPI bus speed ("spi_board_info.max_speed_hz") and the specific
slave device. Please note the the PXA2xx SSP 1 does not support trailing byte
timeouts and must busy-wait any trailing bytes.
The "pxa2xx_spi_chip.enable_loopback" field is used to place the SSP porting
into internal loopback mode. In this mode the SSP controller internally
connects the SSPTX pin the the SSPRX pin. This is useful for initial setup
testing.
The "pxa2xx_spi_chip.cs_control" field is used to point to a board specific
function for asserting/deasserting a slave device chip select. If the field is
NULL, the pxa2xx_spi master controller driver assumes that the SSP port is
configured to use SSPFRM instead.
NSSP SALVE SAMPLE
-----------------
The pxa2xx_spi_chip structure is passed to the pxa2xx_spi driver in the
"spi_board_info.controller_data" field. Below is a sample configuration using
the PXA255 NSSP.

ARRAY_SIZE(streetracer_spi_board_info));
}
DMA and PIO I/O Support
-----------------------
The pxa2xx_spi driver support both DMA and interrupt driven PIO message
transfers. The driver defaults to PIO mode and DMA transfers must enabled by
setting the "enable_dma" flag in the "pxa2xx_spi_master" structure and and
ensuring that the "pxa2xx_spi_chip.dma_burst_size" field is non-zero. The DMA
mode support both coherent and stream based DMA mappings.
The following logic is used to determine the type of I/O to be used on
a per "spi_transfer" basis:
if !enable_dma or dma_burst_size == 0 then
always use PIO transfers
if spi_message.is_dma_mapped and rx_dma_buf != 0 and tx_dma_buf != 0 then
use coherent DMA mode
if rx_buf and tx_buf are aligned on 8 byte boundary then
use streaming DMA mode
otherwise
use PIO transfer

and those methods.)
After you initialize the spi_master, then use spi_register_master() to
publish it to the rest of the system. At that time, device nodes for
the controller and any predeclared spi devices will be made available,
and the driver model core will take care of binding them to drivers.
If you need to remove your SPI controller driver, spi_unregister_master()
will reverse the effect of spi_register_master().
BUS NUMBERING
Bus numbering is important, since that's how Linux identifies a given
SPI bus (shared SCK, MOSI, MISO). Valid bus numbers start at zero. On
SOC systems, the bus numbers should match the numbers defined by the chip
manufacturer. For example, hardware controller SPI2 would be bus number 2,
and spi_board_info for devices connected to it would use that number.
If you don't have such hardware-assigned bus number, and for some reason
you can't just assign them, then provide a negative bus number. That will
then be replaced by a dynamically assigned number. You'd then need to treat
this as a non-static configuration (see above).

Such a transfer() method would normally just add the message to a

already running).
