Put MMC to sleep if it supports SLEEP/AWAKE (CMD5) in the mmc suspend so that Vcc (NAND core) can be cut to minimize power consumption. eMMC put into SLEEP can respond to CMD0 or H/W reset or CMD5. Current implemention on resume from suspend relies on CMD0 in mmc_init_card to get out of SLEEP mode.

Stress-testing the runtime power management of libertas_sdio through a rmmod/insmod loop revealed that it is quite easy to cause an ETIMEDOUT failure in mmc_sdio_power_restore() leading to: libertas_sdio: probe of mmc1:0001:1 failed with error -16 Experimentation shows that a very short delay (100us) is needed in the power down path before the card can be successfully booted again. We know that this setup is lacking poweroff clamps on the card's power lines, but as only a short delay is needed, apply this unconditionally. Also bump up to 1ms sleep for extra legroom.

The previous patch which implemented a DT binding for sdhci-tegra did not allow all platform data fields to be initialized from DT. The following were missing: is_8bit: Implemented by this patch. pm_flags: Not implemented yet. There are no mainline users of this field. I'm not quite sure what it's for, and hence how to represent this in DT; the value ends up being assigned to host->mmc->pm_caps. While we're at it, fix the binding documentation to refer to "SD/MMC" instead of "eSDHC", since that's the correct name; "eSDHC" was cut/paste from the Freescale binding docs.

For clocks that support rates which can be set (most clocks other than _pclk AHB clocks), a rate must be set using clk_set_rate() before the clock is enabled for the first time with clk_enable(). Subsequent calls to clk_enable() need not be preceded with the clk_set_rate() calls unless we wish to change the clock rate that is set previously. SDC host->clk is currently enabled without setting the clock rate even once. This patch fixes this, by ensuring that the clock rate for this clock is first set before enabling the clock.

由 Daniel Drake 提交于
Now that we have improved the runtime power management powerup/powerdown code, we believe that MMC_CAP_POWER_OFF_CARD is no longer necessary: runtime PM should now work everywhere. The only hard evidence for introducing MMC_CAP_POWER_OFF_CARD was the Marvell sd8686 wifi chip, which was believed to require external gpio manipulation which wasn't supported by some boards. After further investigation it was realized (and confirmed by Marvell folks) that sd8686 requirements can be fulfilled by changing the reset sequence itself, even if no external gpio is manipulated. For further information, see the following thread: http://www.mail-archive.com/linux-mmc@vger.kernel.org/msg04289.html Enable this trivially for a release or two. If no problems are reported, we will follow up with a more extensive patch to remove this flag altogether. If problems are reported, we can look at whitelist/blacklist possibilities as before.

This adds support to inject data errors after a completed host transfer. The mmc core will return error even though the host transfer is successful. This simple fault injection proved to be very useful to test the non-blocking error handling in the mmc_blk_issue_rw_rq(). Random faults can also test how the host driver handles pre_req() and post_req() in case of errors.

This patch fixes a potential issue about PDC interrupts. For example we have a ENDRX pending interrupt and a RXBUFF pending interrupt. We have received the RXBUFF interrupt but the transfer is not finished (so we didn't have time to give a new buffer to the PDC controller). Then we will compute ENDRX interrupt and we will give a new buffer to the PDC controller, just after we will compute the RXBUFF interrupt and give one or two new buffers to the PDC controller but we are not sure that the first buffer given has been filled. So in this situation we may have "lost" one sg buffer. It's the same for transmission.
