2015-04-10mmc: sdhci-st: Update the quirks for this controller.Peter Griffin1-1/+4
Some additional quirks need to be enabled now we support UHS modes.

2015-04-10mmc: sdhci-st: Add sdhci_st_set_uhs_signaling function.Peter Griffin1-0/+51
To allow UHS modes to work properly we need to provide the st specific set_uhs_signaling callback function. This function differs from the generic sdhci_set_uhs_signaling callback in that we need to configure the correct delay depending on the UHS mode, and also set the V18_EN bit.

2015-04-10mmc: sdhci-st: Add delay management functions for top registers (eMMC).Peter Griffin1-0/+59
Due to the tight timing constraints in some UHS modes, it is required to have some delay management in the design. Two types of delay management are supported in the HW: - 1) Static delay management 2) Dynamic delay management NB: The delay management is only there when eMMC interface is selected. 1: Static delay management: is used to provide PVT dependent static delay on the clock/data lines to manage setup/hold requirements of the interface. The maximum delay possible is 3.25ns. These delays are PVT dependent, and thus delay values applied are not accurate and vary across provcess voltage and temperature range. Due to this these delays must not be used on the very time critical paths. 2. Dynamic delay locked loop (DLL): is used to provide dynamic delay management. The advantage of DLL is that it provides accurate & PVT indepedent delay. The DLL is used to provide delay on the loopback clock on "Read Path" to capture read data reliably. On TX path the clock on which output data is transmitted is delayed, resulting in delay of TX data.

2015-04-09mmc: sdhci-esdhc-imx: Call mmc_of_parse()Fabio Estevam1-32/+6
Currently it is not possible to use 'mmc-pwrseq-simple' property with this driver because mmc_of_parse() is never called. mmc_of_parse() calls mmc_pwrseq_alloc() that manages MMC power sequence and allows passing GPIOs in the devicetree to properly power/reset the Wifi chipset. When using mmc_of_parse() we no longer need to have custom code to request card-detect and write-protect pins, as this can now be handled by the mmc core. Tested on a imx6sl-warp board where BT/Wifi is functional and also on a imx6q-sabresd. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>

It is possible for the cmd11 interrupt to fire and delete the cmd11_timer before the cmd11_timer was actually setup. Let's fix this race by adding a few spinlocks.

Although the cmd11 interrupt should come within 2ms, that's a very short time. Let's increase the timeout to be really sure that we don't get an accidnetal timeout. One case in particular this is useful is if you've got a serial console and printk in just the right places. Under that scenario I've seen delays of up to 130ms before the interrupt fired. CMD11 is only sent during card insertion, so this extra timeout shouldn't be terrible.

The dw_mmc driver changes to make the IO accesors endian agnostic did not take into account the fifo accesses do not need to be swapped. To fix this add a mmci_fifo_read/write wrapper to allow these to be passed through the IO without being swapped. Since these are now specific functions, it would be easier just to store the pointer to the fifo registers in the host block instead of the offset to them. So change the host->data_offset to host->fifo_reg (which also means we catch all the places this is read or written).

Note that if we have more than one slot and one defers (but the others don't) things won't work so well. ...but that's not a new thing and everyone has already agreed that multislot support ought to be removed from dw_mmc eventually anyway since it is unused, untested, and you can see several bugs like this by inspecting the code.

2015-03-31mmc: core: Enable runtime PM management of host devicesUlf Hansson1-1/+9
Currently those host drivers which have deployed runtime PM, deals with the runtime PM reference counting entirely by themselves. Since host drivers don't know when the core will send the next request through some of the host_ops callbacks, they need to handle runtime PM get/put between each an every request. In quite many cases this has some negative effects, since it leads to a high frequency of scheduled runtime PM suspend operations. That due to the runtime PM reference count will normally reach zero in-between every request. We can decrease that frequency, by enabling the core to deal with runtime PM reference counting of the host device. Since the core often knows that it will send a seqeunce of requests, it makes sense for it to keep a runtime PM reference count during these periods. More exactly, let's increase the runtime PM reference count by invoking pm_runtime_get_sync() from __mmc_claim_host(). Restore that action by invoking pm_runtime_mark_last_busy() and pm_runtime_put_autosuspend() in mmc_release_host(). In this way a runtime PM reference count will be kept during the complete cycle of a claim -> release host.

2015-03-27ARM: OMAP2: HSMMC: explicit fields to declare cover/card detect pinAndreas Fenkart1-5/+6
board-rx51 has no card detect pin in the mmc slot, but can detect that the (cell-phone) cover has been removed and the card is accessible. The semantics between cover/card detect differ, the gpio on the slot informs you after the card has been removed, cover removal does not necessarily mean that the card has been removed. This means different code paths are necessary. To complete this we also want different fields in the platform data for cover and card detect. This separation is not pushed all the way down into struct omap2_hsmmc_info which is used to initialize the platform data. If we did that we had to go over all board files and set the new gpio_cod pin to -EINVAL. If we forget one board or some out-of-tree archicture forgets that the default '0' is used which is a valid pin number.

2015-03-23mmc: sunxi: avoid invalid pointer calculationArnd Bergmann1-2/+3
The sunxi mmc driver tries to calculate a dma address by using pointer arithmetic, which causes a warning when dma_addr_t is wider than a pointer: drivers/mmc/host/sunxi-mmc.c: In function 'sunxi_mmc_init_idma_des': drivers/mmc/host/sunxi-mmc.c:296:35: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] struct sunxi_idma_des *pdes_pa = (struct sunxi_idma_des *)host->sg_dma; ^ To avoid this warning and to simplify the logic, this changes the code to avoid the cast and calculate the correct address manually. The behavior should be unchanged. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Acked-by: David Lanzendörfer <david.lanzendoerfer@o2s.ch> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
2015-03-23mmc: kconfig: replace PPC_OF with PPCKevin Hao1-2/+2
The PPC_OF is a ppc specific option which is used to mean that the firmware device tree access functions are available. Since all the ppc platforms have a device tree, it is aways set to 'y' for ppc. So it makes no sense to keep a such option in the current kernel. Replace it with PPC. Signed-off-by: Kevin Hao <haokexin@gmail.com> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>

2015-03-23mmc: sdhci: do not set AUTO_CMD12 for multi-block CMD53Corneliu Doban1-1/+3
For CMD53 in block mode, the host does not need to stop the transfer, as it stops when the block count (present in CMD53) is reached. Signed-off-by: Corneliu Doban <cdoban@broadcom.com> Signed-off-by: Scott Branden <sbranden@broadcom.com> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
2015-03-23mmc: sdhci: add quirk for ACMD23 brokenScott Branden1-1/+2
Add quirk to handle broken auto-CMD23. Some controllers do not respond after the first auto-CMD23 is issued. This allows CMD23 to still work (mandatory for the faster UHS-I mode) rather than disabling CMD23 entirely via SDHCI_QUIRK2_HOST_NO_CMD23.
