tmio_mmc_host has .enable_dma callback now. We don't need TMIO_MMC_HAVE_CTL_DMA_REG anymore. Let's remove it Signed-off-by:

Renesas SDHI which is based on TMIO driver has 2 type SoC. 1st one is used as SH-Mobile series, and 2nd is R-Car series. R-Car series SoC has DMA buswidth setting register which enables 32bit access. This patch adds .dma_buswidth and enables it. Signed-off-by:

Current tmio_mmc driver is using tmio_mmc_data for driver/platform specific data/callback, and it is needed for tmio_mmc_host_probe() function. Because of this style, include/linux/mfd/tmio.h header has tmio driver/framework specific data which is not needed from platform. This patch adds new tmio_mmc_host_alloc/free() as cleanup preparation. tmio driver specific data/callback will be implemented in tmio_mmc_host, and platform specific data/callback will be implemented in tmio_mmc_data in this cleanup.

If we power up vqmmc in MMC_POWER_ON then we end up turning it on before mmc_power_up() sets the signal voltage. That's not so great since we might be powering it up at the wrong voltage. Note that this is how Yuvaraj originally coded things up in <https://patchwork.kernel.org/patch/4401231/> but he changed it on my suggestion. Apparently I was wrong. Reported-by:

Commit 0dcaa249 ("sdhci-pxav3: Fix runtime PM initialization") tries to fix one hang issue caused by calling sdhci_add_host() on a suspended device. The fix enables the clock twice, once by clk_prepare_enable() and another by pm_runtime_get_sync(), meaning that the clock will never be gated at runtime PM suspend. I observed the power consumption regression on Marvell BG2Q SoCs. In fact, the fix is not correct. There still be a very small window during which a runtime suspend might somehow occur after pm_runtime_enable() but before pm_runtime_get_sync(). This patch fixes all of the two problems by just incrementing the usage counter before pm_runtime_enable(). It also adjust the order of disabling runtime pm and storing the usage count in the error path to handle clock gating properly. Signed-off-by:

There is no point making the initialization of buf_ready_int conditional on host version. Simplify by just doing it always. Note that the other conditional initializations will be removed when the new way of doing re-tuning is taken into use. Signed-off-by:

For each MMC, SD and SDIO there is code that holds the clock, calls ops->execute_tuning, and releases the clock. Simplify the code a bit by providing a separate function to do that. Signed-off-by:

Using the common code removes some code duplication, and makes it easier to switch to using mmc_of_parse() which will remove more duplication. This uses the new mmc_gpio_request_cd_isr to provide a non-standard interrupt service routine for card-detect interrupts. Signed-off-by:

NeilBrown authored
One of the reasons omap_hsmmc doesn't use the slot-gpio library is that it has some non-standard functionality in the card-detect interrupt service routine. To make it possible for omap_hsmmc (and maybe others) to be converted to use slot-gpio, add 'mmc_gpio_request_cd_isr' which provide an alternate isr to be register by the slot-gpio code.

Move the (e)MMC specific hw_reset code from core.c into mmc.c. Call the code from the new bus_ops member "reset". This also allows for adding a SD card specific reset procedure. Signed-off-by:

Always check if the card is alive after a successful reset. This allows us to remove mmc_hw_reset_check(), leaving mmc_hw_reset() as the only card reset interface. Signed-off-by:

This adds SDIO devicetree subnode parsing to the mmc core. While SDIO devices are runtime probable they sometimes need nonprobable additional information on embedded systems, like an additional gpio interrupt or a clock. This patch makes it possible to supply this information from the devicetree. SDIO drivers will find a pointer to the devicenode in their devices of_node pointer. Signed-off-by:
