2009-12-11tty: sdio_uart: Fix the locking on "func" for new codeAlan Cox
The new dtr_rts function didn't take the port->func lock as it should so add use of the lock there. Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2009-12-11tty: sdio_uart: add modem functionalityAlan Cox
Add the POSIX block for carrier Linux TIOCMIWAIT functionality is still lacking from the driver. Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2009-12-11tty: sdio_uart: Style fixesAlan Cox
Running the current code through checkpatch shows a few bits of noise mostly but not entirely from before the changes. Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2009-12-11tty: sdio_uart: Fix termios handlingAlan Cox
Switching between two non standard baud rates fails because of the cflag test. Do as we did elsewhere and just kill the "optimisation". Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2009-12-11tty: sdio_uart: Switch to the open/close helpersAlan Cox
Gets us proper tty semantics, removes some code and fixes up a few corner case races (hangup during open etc) Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2009-12-11sdio_uart: Move the open lockAlan Cox
When we move to the tty_port logic the port mutex will protect open v close v hangup. Move to this first in the existing open code so we have a bisection point. Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2009-12-11sdio_uart: refcount the tty objectsAlan Cox
The tty can go away underneath us, so we must refcount it. Do the naïve implementation initially. We will worry about startup shortly. Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2009-12-02[ARM] pxamci: call mmc_remove_host() before freeing resourcesDaniel Mack
mmc_remove_host() will cause the mmc core to switch off the bus power by eventually calling pxamci_set_ios(). This function uses the regulator or the GPIO which have been freed already.

Add better support for omitting either the card detect or the write protect GPIOs if the board does not support it. Add the fields no_wprotect and no_detect to the platform data which when set indicate the absence of the respective GPIOs. Note, this also fixes a minor bug where it tries to free IRQ0 if there is no detect gpio available.

2009-10-01s3cmci: DMA fixesBen Dooks
Fixes for the DMA transfer mode of the driver to try and improve the state of the code: - Ensure that dma_complete is set during the end of the command phase so that transfers do not stall awaiting the completion - Update the DMA debugging to provide a bit more useful information such as how many DMA descriptors where not processed and print the DMA addresses in hexadecimal. - Fix the DMA channel request code to actually request DMA for the S3CMCI block instead of whatever '0' signified. - Add fallback to PIO if we cannot get the DMA channel, as many of the devices with this block only have a limited number of DMA channels. - Only try and claim and free the DMA channel if we are trying to use it. This improves the driver DMA code to the point where it can now identify a card and read the partition table. However the DMA can still stall when trying to move data between the host and memory.

2009-10-01s3cmci: Kconfig selection for PIO/DMA/BothBen Dooks
Add a selection for the data transfer mode of the s3cmci driver, allowing for either a configuration or rumtime selection of the use of the DMA or PIO transfer code. The PIO only mode is 476 bytes smaller than the driver with both methods compiled in.

2009-10-01s3cmci: add SDIO IRQ supportBen Dooks
The controller supports SDIO IRQ detection so add support for hardware assisted SDIO interrupt detection for the SDIO core. This improves the response time for SDIO interrupts and thus the transfer rate from devices such as the Marvel 8686. As a note, it does seem that the controller will miss an IRQ than is held asserted, so there are some manual checks to see if the SDIO interrupt is active after a transfer. Major testing on the S3C2440.

2009-10-01s3cmci: add debugfs support for examining driver and hardware stateBen Dooks
Export driver state and hardware register state via debugfs entries created under a directory formed from dev_name() on the probed device when CONFIG_DEBUG_FS is set.

2009-10-01s3cmci: fix direct write to interrupt maskBen Dooks
The clear_imask() call should be used to clear the interrupt mask register, as it may end up clearing the SDIO interrupt bit if this is enabled. Change all writes of zero to SDIIMSK register to use clear_imask() ready for the SDIO updates.

2009-10-01s3cmci: change GPIO to gpiolib from S3C24XX specific callsBen Dooks
Move to using gpiolib to access the card detect and write protect GPIO lines instead of using the platform speicifc s3c2410_gpio calls. Also ensure that the card lines are claimed the same way to avoid overlap with any other drivers.

2009-10-01s3cmci: update probe to use new platform id listBen Dooks
Use the platform id list to match the three different versions of the hardware block that this driver supports. This will change the prefix of the console messages produced by this driver to be prefixed by s3c-mci instead of the hardware block name, such as s3c2440-mci.

2009-10-01sdio: pass whitelisted cis funce tuples to sdio driversAlbert Herranz
Some manufacturers provide vendor information in non-vendor specific CIS tuples. For example, Broadcom uses an Extended Function tuple to provide the MAC address on some of their network cards, as in the case of the Nintendo Wii WLAN daughter card. This patch allows passing whitelisted FUNCE tuples unknown to the SDIO core to a matching SDIO driver instead of rejecting them and failing.
