Marvell pxa controllers have private registers that may need to be modified before and after a reset is done. For example, the SD reset operation, RESET_ALL, will reset the private registers to their default state. This will cause the clock adjustment registers that may have been programmed to have incorrect values. RESET_DATA sometimes needs to be delayed before the reset is done (depending on SoC) to enable any transactions being handled by the SDIO card to be completed. Needed in pre SD 3.0 silicon to handle clock gating. Implement hooks to allow this to happen. Signed-off-by: NPhilip Rakity <prakity@marvell.com> Signed-off-by: NChris Ball <cjb@laptop.org>

Some SD host controllers (noticed on an integrated JMicron SD reader on an HP Pavilion dv5-1250eo laptop) don't update the dma address register before signaling a dma interrupt due to a dma boundary. Update the register manually to the next boundary (by default 512KiB), at which the transfer stopped. As long as each transfer is at most 512KiB in size (guaranteed by a BUG_ON in sdhci_prepare_data()) and the boundary is kept at the default value, this fix is needed at most once per transfer. Smaller boundaries are taken care of by counting the transferred bytes.

We now: * check for a v3 controller before setting 8-bit bus width * offer a callback for platform code to switch to 8-bit mode, which allows non-v3 controllers to support it * rely on mmc->caps |= MMC_CAP_8_BIT_DATA; in platform code to specify that the board designers have indeed brought out all the pins for 8-bit to the slot. We were previously relying only on whether the *controller* supported 8-bit, which doesn't tell us anything about the pin configuration in the board design. This fixes the MMC card regression reported by Maxim Levitsky here: http://thread.gmane.org/gmane.linux.kernel.mmc/4336 by no longer assuming that 8-bit works by default.

Some platforms based on sdhci-pltfm need to set their own quirks. Previously to this patch, the quirks were in drivers/mmc/host/sdhci.h. This patch splits drivers/mmc/host/sdhci.h into two parts: * drivers/mmc/host/sdhci.h includes the HC registers and I/O accessors. * include/linux/mmc/sdhci.h includes the sdhci structure and quirks. Instead of including drivers/mmc/host/sdhci.h, -pltfm drivers should now include include/linux/mmc/sdhci.h and include/linux/sdhci-pltfm.h. This patch avoids adding/changing the calls/flags in the sdhci_pltfm_data structure. It has been tested on STM platforms (e.g. STx7106, STx7108, STx5206) where the driver is configured and used as shown in the example below: [snip] static int mmc_pad_resources(struct sdhci_host *sdhci) { if (!devm_stm_pad_claim(sdhci->mmc->parent, &stx7108_mmc_pad_config, dev_name(sdhci->mmc->parent))) return -ENODEV; return 0; } static struct sdhci_pltfm_data stx7108_mmc_platform_data = { .init = mmc_pad_resources, .quirks = SDHCI_QUIRK_NO_ENDATTR_IN_NOPDESC, }; static struct platform_device stx7108_mmc_device = { .name = "sdhci", [snip] Note: drivers/mmc/host/sdhci.h now also includes linux/mmc/sdhci.h, and no modifications should be needed on other sdhci-<XXX> drivers.

On some Samsung SoCs not all SDHCI controllers have card detect (CD) line. For some embedded designs it is not even needed, because ususally the device (like SDIO flash memory or wifi controller) is permanently wired to the controller. There are also systems which have a card detect line connected to some of the external interrupt lines or the presence of the card depends on some other actions (like enabling a power regulator). This patch adds support for all these cases. The following card detection methods are possible: 1. internal sdhci host card detect line 2. external event 3. external gpio interrupt 4. no card detect line, controller will poll for the card 5. no card detect line, card is permanently wired to the controller (once detected host won't poll it any more) By default, all existing code would use method #1, what is compatible with the previous version of the driver. In case of external event, two callbacks must be provided in platdata: ext_cd_init and ext_cd_cleanup. Both of them get a callback to a function that notifies the s3c-sdhci host contoller as their argument. That callback function should be called from the even dispatcher to let host notice the card insertion/removal. In case of external gpio interrupt, a gpio pin number must be provided in platdata (ext_cd_gpio parameter), as well as the information about the polarity of that gpio pin (ext_cd_gpio_invert). By default (ext_cd_gpio_invert == 0) gpio value 0 means 'card has been removed', but this can be changed to 'card has been removed' when ext_cd_gpio_invert == 1. This patch adds all required changes to sdhci-s3c driver.

eSDHC fails to recognize some SDHS cards, throwing timeout errors: mmc0: error -110 whilst initialising SD card That's because we calculate timeout value in a wrong way: on eSDHC hosts the timeout clock is derivied from the SD clock, which is set dynamically. As David Vrabel suggested, deriving timeout clock from SD clock is a common scheme, so let's implement DATA_TIMEOUT_USES_SDCLK quirk and use it for eSDHC hosts. Also, from now on we don't need esdhc_get_timeout_clock() callback, so remove it.

Since commit 8dfd0374 ("MMC core: limit minimum initialization frequency to 400kHz") MMC core checks for minimum frequency, and that causes following messages flood when using eSDHC controllers: ... mmc0: Minimum clock frequency too high for identification mode mmc0: Minimum clock frequency too high for identification mode ... The warnings are legitimate, since if we'd use 133 MHz clocks for standard SDHCI controllers, we'd not able to scale frequency down to 400 kHz. But eSDHC controllers have a non-standard SD clock management, so we can divide clock by 256 * 16, not just 256. This patch introduces get_min_clock() callback for sdhci core and implements it for sdhci-of driver, and thus fixes the issue.

Card detection interrupts should be handled separately as they should not be enabled before mmc_add_host() returns and should be disabled before calling mmc_remove_host(). The same is for suspend and resume routines. sdhci_init() no longer enables card-detection irqs. Instead, two new functions implemented: sdhci_enable_card_detection() and sdhci_disable_card_detection(). New sdhci_reinit() call implemented to behave the same way as the old sdhci_init(). Also, this patch implements and uses few new helpers to manage IRQs in a more conveinient way, that is: - sdhci_clear_set_irqs() - sdhci_unmask_irqs() - sdhci_mask_irqs() - SDHCI_INT_ALL_MASK constant sdhci_enable_sdio_irq() converted to these new helpers, plus the helpers will be used by the subsequent patches.
