2014-11-26mmc: omap_hsmmc: remove unnecessary omap_hsmmc_slot_data indirectionAndreas Fenkart
omap_hsmmc supports only one slot per controller, see OMAP_MMC_MAX_SLOTS. This unnecessary indirection leads to confusion in the omap_hsmmc driver. For example the card_detect callback is not installed by platform code but from the driver probe function. So it should be a field of omap_hsmmc_host. But since it is declared under the platform slot while the drivers struct omap_hsmmc_host has no slot abstraction, this looks like a bug, especially when not familiar that this driver only supports 1 slot anyway. Either we should add a slot abstraction to omap_hsmmc_host or remove it from the platform data struct. Removed since slot multiplexing is an un-implemented feature Acked-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Andreas Fenkart <afenkart@gmail.com> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>

2014-11-26ARM: OMAP1/2+: MMC: separate platform data for mmc and mmc hs driverAndreas Fenkart
- omap mmc driver supports multiplexing, omap_mmc_hs doesn't this leads to one of the major confusions in the omap_hsmmc driver - platform data should be read-only for the driver most callbacks are not set by the omap3 platform init code while still required. So they are set from the driver probe function, which is against the paradigm that platform-data should not be modified by the driver typical examples are card_detect, read_only callbacks un-bundling by searching for driver name \"omap_hsmmc in the arch/arm folder. omap_hsmmc_platform_data is not initialized directly, but from omap2_hsmmc_info, which is defined in a separate header file not touched by this patch hwmod includes platform headers to declare features of the platform. All the declared features are prefixed OMAP_HSMMC. There is no need to include platform header from hwmod other except for feature defines Acked-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Andreas Fenkart <afenkart@gmail.com> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>

2014-07-09mmc: omap_hsmmc: Pin remux workaround to support SDIO interrupt on AM335xAndreas Fenkart
The am335x can't detect pending cirq in PM runtime suspend. This patch reconfigures dat1 as a GPIO before going to suspend. SDIO interrupts are detected with the GPIO, the GPIO will only wake the module from suspend, SDIO irq detection will still happen through the IP block. Idea of remuxing the pins by Tony Lindgren.

2014-07-09mmc: omap_hsmmc: switch default/idle pinctrl states in runtime hooksAndreas Fenkart
These are predefined states of the driver model. When not present, as if not set in the device tree, they become no-ops. Explicitly selecting the default state is not needed since the device core layer sets pin mux to "default" state before probe. This is not the simplest implementation, on AM335x at least, we could switch to idle at any point in the suspend hook, only the default state needs to be set before writing to the irq registers or an IRQ might get lost.

2014-07-09mmc: omap_hsmmc: abort runtime suspend if pending sdio irq detectedAndreas Fenkart
On multicores, an sdio irq handler could be running in parallel to runtime suspend. In the worst case it could be waiting for the spinlock held by the runtime suspend. When runtime suspend is complete and the functional clock (fclk) turned off, the irq handler will continue and cause a SIGBUS on the first register access.

2014-07-09mmc: omap_hsmmc: Enable SDIO interruptAndreas Fenkart
There have been various patches floating around for enabling the SDIO IRQ for hsmmc, but none of them ever got merged. Probably the reason for not merging the SDIO interrupt patches has been the lack of wake-up path for SDIO on some omaps that has also needed remuxing the SDIO DAT1 line to a GPIO making the patches complex. This patch adds the minimal SDIO IRQ support to hsmmc for omaps that do have the wake-up path. For those omaps, the DAT1 line need to have the wake-up enable bit set, and the wake-up interrupt is the same as for the MMC controller. This patch has been tested on am3730 es1.2 with mwifiex connected to MMC3 with mwifiex waking to Ethernet traffic from off-idle mode. Note that for omaps that do not have the SDIO wake-up path, this patch will not work for idle modes and further patches for remuxing DAT1 to GPIO are needed. Based on earlier patches [1][2] by David Vrabel <david.vrabel@csr.com>, Steve Sakoman <steve@sakoman.com> For now, only support SDIO interrupt if we are booted with a separate wake-irq configued via device tree. This is because omaps need the wake-irq for idle states, and some omaps need special quirks. And we don't want to add new legacy mux platform init code callbacks any longer as we are moving to DT based booting anyways. To use it, you need to specify the wake-irq using the interrupts-extended property.

2013-08-25mmc: omap_hsmmc: clear status flags before starting a new commandFrancesco Lavra
Commit 1f6b9fa40e76fffaaa0b3bd6a0bfdcf1cdc06efa consolidated writes to the STAT register in one location, moving them from omap_hsmmc_do_irq() to omap_hsmmc_irq(). This move has the unwanted side effect that the controller status flags are potentially cleared after a new command has been started as a consequence of reading the previous status flags. This means that if the new command changes the status flags before the IRQ routine returns, those flags may be cleared without handling the event which asserted them, and thus missing the event. Move the writing of the STAT register back in omap_hsmmc_do_irq(), before handling the status flags which generated the interrupt.

2012-12-06mmc: omap_hsmmc: Cleanup bitmap definitions of Interrupt RegisterVenkatraman S
Define the most frequently used bitmasks of the Interrupt Enable / Interrupt Status register with consistent naming ( with _EN suffix). Use meaningful concatenation of bitfields for INT_EN_MASK, which shows which interrupts are enabled by default. No functional changes.

2012-12-06mmc: omap_hsmmc: Convert critical failure reports to dev_errVenkatraman S
Fatal errors for the driver are not reported when just error debug is enabled. Convert selected dev_dbg to dev_err for accurate error reporting. Reported-by: Benoit Cousson <b-cousson@ti.com> Signed-off-by: Venkatraman S <svenkatr@ti.com> Signed-off-by: Chris Ball <cjb@laptop.org>
2012-12-06mmc: omap_hsmmc: Introduce omap_hsmmc_prepare/completeFelipe Balbi
prepare() is supposed to prevent new children from being registered. On the MMC subsystem, children (new cards) registration starts with the card detect IRQ. Move card detect IRQ disabling to prepare() so that no new cards will be registered while we're trying to suspend. Likewise, move card detect IRQ enabling to complete() so we only try to register new children after our MMC IP is back up.
