Suspend and resume of cards are being handled from the protocol layer and consequently the mmc_suspend|resume_host APIs are deprecated. This means we can simplify the suspend|resume callbacks by removing the use of the deprecated APIs.

We want to give user space provision to fully consume a card insert/remove event, when the event was caused by a wakeup irq. By signaling the wakeup event for a time of 5 s for devices configured as wakeup capable, we likely will be prevent a sleep long enough to let user space consume the event. To enable this feature, host drivers must thus configure their devices as wakeup capable. This is a reworked implementation of the old wakelocks for the mmc subsystem, originally authored by Colin Cross and San Mehat for the Android kernel. Zoran Markovic shall also be given cred for recently re-trying to upstream this feature.

Since mmc_select_voltage now only gets called from the attach sequence, it makes sense to move the out of spec validations of the card ocr into this function. Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org> Signed-off-by: Chris Ball <cjb@laptop.org>

According to eMMC/SD/SDIO specs, the VDD (VCC) voltage level must be maintained during the initialization sequence. If we want/need to tune the voltage level, a complete power cycle of the card must be executed. Most host drivers conforms to the specifications by only allowing to change VDD voltage level at the MMC_POWER_UP state, but some also cares about MMC_POWER_ON state, which they should'nt. This patch will not break those drivers, but they could clean up code to better reflect what is expected from the protocol layer. A big re-work of the mmc_select_voltage function is done to only change VDD voltage level if the host supports MMC_CAP2_FULL_PWR_CYCLE. Otherwise only validation of the host and card ocr mask will be done. A very nice side-effect of this patch is that we now don't need to reset the negotiated ocr mask at the mmc_power_off function, since now it will actually reflect the present voltage level, which safely can be used at the next power up and re-initialization. Moreover, we then only need to execute mmc_select_voltage from the attach sequence. Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org> Signed-off-by: Chris Ball <cjb@laptop.org>

The negotiated ocr mask is directly related to the card. Once a card gets removed, the mask shall be dropped. By moving the cache of the ocr mask from the host struct to the card struct we have accomplished this. Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org> Signed-off-by: Chris Ball <cjb@laptop.org>

At several places in mmc_sdio_init_card function the cached mask in host->ocr were being updated. To simplify code, we make use of an local ocr parameter instead. Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org> Signed-off-by: Chris Ball <cjb@laptop.org>

Some switch operations like poweroff notify, shall according to the spec not be followed by any other new commands. For these cases and when the host does'nt support MMC_CAP_WAIT_WHILE_BUSY, we must not send status commands to poll for busy detection. Instead wait for the stated timeout from the EXT_CSD before completing the request.

pbias_disable is set to protect the mmc pbias i/o cells in DT boot by preventing voltage switch. Currently pbias_disable is enabled only for omap3 and not for omap4 due to reg_offset difference of 0x100.
