mmc: Convert timers to use timer_setup()

2017-11-02T14:20:28+00:00

In preparation for unconditionally passing the struct timer_list pointer to all timer callbacks, switch to using the new timer_setup() and from_timer() to pass the timer pointer explicitly.

mmc: mvsdio: delete platform data code path

2015-12-22T10:32:12+00:00

There are no in-kernel users of the MVSDIO platform data method (instantiating from a board file) so just delete this code and make this a DT-only driver. We depend on OF and check that we have an OF node in probe().

mmc: mvsdio: delete platform data header

2015-12-22T10:32:12+00:00

This platform data struct is only used inside the MVSDIO driver, nowhere else in the entire kernel. Move the struct into the driver and delete the external header.

mmc: mvsdio: don't use devm_pinctrl_get_select_default() in probe

2015-01-19T08:56:21+00:00

Since commit ab78029ecc34 (drivers/pinctrl: grab default handles from device core), we can rely on device core for setting the default pins. Signed-off-by: Wolfram Sang Signed-off-by: Ulf Hansson

mmc: mvsdio: Remove redundant use of mmc_gpio_free_cd|ro()

2015-01-19T08:56:15+00:00

The MMC core makes use of the devm_* functions while requesting the CD/WP GPIOs, let's rely on that. Cc: Nicolas Pitre Signed-off-by: Ulf Hansson

mmc: mvsdio: Work around broken TX DMA

2014-11-26T13:31:00+00:00

In order to use the mvsdio driver for sdio, it has been necessary to use a module parameter to disable DMA so to force PIO is used. It is then possible to use wireless LAN devices like mwifiex found on topkick and mirabox. However, accessing an MMC SD card does work with DMA. Investigation has shown that MMC block device accesses are always aligned to 64 byte boundaries, where as transfers from mwifiex are rarely more than word aligned. It has also been determined that card to host transfers work with DMA for SDIO devices, but host to card transfers with DMA have problems. This patch extends the current checks for buffers which are not word aligned or multiple of words. All host to card transfers which are not 64 byte aligned are now also performed via PIO. This should not affect the performance of SD cards, but allow sdio devices to work out of the box, and they are likely to be more efficient since DMA will be used for card to host transfers. Tested on mirabox for wifi via mwifiex Tested on 370 RD for file systems on an SD card. Signed-off-by: Andrew Lunn Signed-off-by: Ulf Hansson

mmc: mvsdio: avoid compiler warning

2014-06-12T08:50:27+00:00

gcc correctly points out that hw_state can be used uninitially in the mvsd_setup_data() function. This rearranges the function to ensure it always contains a proper value.

mmc: mvsdio: workaround for spurious irqs

2014-05-12T22:05:46+00:00

SDIO controllers found on Marvell Kirkwood SoCs seem to cause a late, spurious irq although all interrupts have been disabled. This irq doesn't do any harm, neither to HW nor driver. To avoid some "unexpected irq" warning later, we workaround above issue by bailing out of irq handler early, if we didn't expect any.

mmc: mvsdio: silence card detect notice

2014-05-12T22:05:28+00:00

mvsdio reports method of card detection with dev_notice, while for removable cards it may be sane, for non-removable cards it is not. Also, as the user cannot do anything about it, silence the message by reducing it from dev_notice to dev_dbg.
