sdio_align_size - pads a transfer size to a more optimal value : SDIO function : original transfer size
Pads the original data size with a number of extra bytes in order to avoid controller bugs and/or performance hits (e.g. some controllers revert to PIO for certain sizes).
If possible, it will also adjust the size so that it can be handled in just a single request.
Returns the improved size, which might be unmodified.
Definition at line 219 of file sdio_io.c.
sdio_claim_host - exclusively claim a bus for a certain SDIO function : SDIO function that will be accessed
Claim a bus for a set of operations. The SDIO function given is used to figure out which bus is relevant.
Definition at line 27 of file sdio_io.c.
sdio_disable_func - disable a SDIO function : SDIO function to disable
Powers down and deactivates a SDIO function. Register access to this function will fail until the function is reenabled.
Definition at line 110 of file sdio_io.c.
sdio_enable_func - enables a SDIO function for usage : SDIO function to enable
Powers up and activates a SDIO function so that register access is possible.
Definition at line 59 of file sdio_io.c.
sdio_f0_readb - read a single byte from SDIO function 0 : an SDIO function of the card : address to read : optional status value from transfer
Reads a single byte from the address space of SDIO function 0. If there is a problem reading the address, 0xff is returned and will contain the error code.
Definition at line 624 of file sdio_io.c.
sdio_f0_writeb - write a single byte to SDIO function 0 : an SDIO function of the card : byte to write : address to write to : optional status value from transfer
Writes a single byte to the address space of SDIO function 0. will contain the status of the actual transfer.
Only writes to the vendor specific CCCR registers (0xF0 - 0xFF) are permiited; will be set to -EINVAL for * writes outside this range.
Definition at line 660 of file sdio_io.c.
sdio_get_host_pm_caps - get host power management capabilities : SDIO function attached to host
Returns a capability bitmask corresponding to power management features supported by the host controller that the card function might rely upon during a system suspend. The host doesn't need to be claimed, nor the function active, for this information to be obtained.
Definition at line 689 of file sdio_io.c.
sdio_memcpy_fromio - read a chunk of memory from a SDIO function : SDIO function to access : buffer to store the data : address to begin reading from : number of bytes to read
Reads from the address space of a given SDIO function. Return value indicates if the transfer succeeded or not.
Definition at line 453 of file sdio_io.c.
sdio_memcpy_toio - write a chunk of memory to a SDIO function : SDIO function to access : address to start writing to : buffer that contains the data to write : number of bytes to write
Writes to the address space of a given SDIO function. Return value indicates if the transfer succeeded or not.
Definition at line 470 of file sdio_io.c.
sdio_readb - read a single byte from a SDIO function : SDIO function to access : address to read : optional status value from transfer
Reads a single byte from the address space of a given SDIO function. If there is a problem reading the address, 0xff is returned and will contain the error code.
Definition at line 369 of file sdio_io.c.
sdio_readl - read a 32 bit integer from a SDIO function : SDIO function to access : address to read : optional status value from transfer
Reads a 32 bit integer from the address space of a given SDIO function. If there is a problem reading the address, 0xffffffff is returned and will contain the error code.
Definition at line 573 of file sdio_io.c.
sdio_readsb - read from a FIFO on a SDIO function : SDIO function to access : buffer to store the data : address of (single byte) FIFO : number of bytes to read
Reads from the specified FIFO of a given SDIO function. Return value indicates if the transfer succeeded or not.
Definition at line 487 of file sdio_io.c.
sdio_readw - read a 16 bit integer from a SDIO function : SDIO function to access : address to read : optional status value from transfer
Reads a 16 bit integer from the address space of a given SDIO function. If there is a problem reading the address, 0xffff is returned and will contain the error code.
Definition at line 521 of file sdio_io.c.
sdio_release_host - release a bus for a certain SDIO function : SDIO function that was accessed
Release a bus, allowing others to claim the bus for their operations.
Definition at line 43 of file sdio_io.c.
sdio_set_block_size - set the block size of an SDIO function : SDIO function to change : new block size or 0 to use the default.
The default block size is the largest supported by both the function and the host, with a maximum of 512 to ensure that arbitrarily sized data transfer use the optimal (least) number of commands.
A driver may call this to override the default block size set by the core. This can be used to set a block size greater than the maximum that reported by the card; it is the driver's responsibility to ensure it uses a value that the card supports.
Returns 0 on success, -EINVAL if the host does not support the requested block size, or -EIO (etc.) if one of the resultant FBR block size register writes failed.
Definition at line 159 of file sdio_io.c.
sdio_set_host_pm_flags - set wanted host power management capabilities : SDIO function attached to host
Set a capability bitmask corresponding to wanted host controller power management features for the upcoming suspend state. This must be called, if needed, each time the suspend method of the function driver is called, and must contain only bits that were returned by sdio_get_host_pm_caps(). The host doesn't need to be claimed, nor the function active, for this information to be set.
Definition at line 710 of file sdio_io.c.
sdio_writeb - write a single byte to a SDIO function : SDIO function to access : byte to write : address to write to : optional status value from transfer
Writes a single byte to the address space of a given SDIO function. will contain the status of the actual transfer.
Definition at line 401 of file sdio_io.c.
sdio_writeb_readb - write and read a byte from SDIO function : SDIO function to access : byte to write : address to write to : optional status value from transfer
Performs a RAW (Read after Write) operation as defined by SDIO spec - single byte is written to address space of a given SDIO function and response is read back from the same address, both using single request. If there is a problem with the operation, 0xff is returned and will contain the error code.
Definition at line 426 of file sdio_io.c.
sdio_writel - write a 32 bit integer to a SDIO function : SDIO function to access : integer to write : address to write to : optional status value from transfer
Writes a 32 bit integer to the address space of a given SDIO function. will contain the status of the actual transfer.
Definition at line 602 of file sdio_io.c.
sdio_writesb - write to a FIFO of a SDIO function : SDIO function to access : address of (single byte) FIFO : buffer that contains the data to write : number of bytes to write
Writes to the specified FIFO of a given SDIO function. Return value indicates if the transfer succeeded or not.
Definition at line 504 of file sdio_io.c.
