2020-07-13mmc: sdhci-msm: Demote faux kerneldoc header down to basic comment blockLee Jones
__sdhci_msm_set_clock()'s function header is the only one in kerneldoc format. Which seems odd as it's not part of an external API and isn't referenced anywhere else. Seeing as there has also been no attempt to describe the expected function arguments either, we're going to assume that this is not actually a bona fide kerneldoc use-case. Fixes the following W=1 kernel build warnings: drivers/mmc/host/sdhci-msm.c:1595: warning: Function parameter or member 'host' not described in '__sdhci_msm_set_clock' drivers/mmc/host/sdhci-msm.c:1595: warning: Function parameter or member 'clock' not described in '__sdhci_msm_set_clock' Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Andy Gross <agross@kernel.org> Cc: Bjorn Andersson <bjorn.andersson@linaro.org> Cc: linux-arm-msm@vger.kernel.org Signed-off-by: Lee Jones <lee.jones@linaro.org> Link: https://lore.kernel.org/r/20200701124702.908713-14-lee.jones@linaro.org Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
2020-07-13mmc: sdhci-of-arasan: Correct formatting and provide missing function arg(s)Lee Jones
Kerneldoc expects arg descriptions to be in the format '@.*: '. If either the '@' or the ':' is omitted then kerneldoc complains that the description is missing. Add the missing ':' here and provide a new description for 'value'.

2020-07-13mmc: sdhci-msm: Use internal voltage controlVeerabhadrarao Badiganti
On qcom SD host controllers voltage switching be done after the HW is ready for it. The HW informs its readiness through power irq. The voltage switching should happen only then. Use the internal voltage switching and then control the voltage switching using power irq. IO-bus supply of eMMC would be kept always-on. So set the load for this supply to configure it in LPM when eMMC is suspend state and in HPM when eMMC is active.

After this patch, commit 7310ece86ad7 ("mmc: implement SD-combo (IO+mem) support") used new sdio_enable_4bit_bus() instead of sdio_enable_wide() to support SD-combo cards, also for card resume. However, no corresponding support added during suspend. That is not correct. Let's fix it.

combo card If the card type is SD combo(MMC_TYPE_SD_COMBO) and the memory part does not support wider bus(SD_SCR_BUS_WIDTH_4), nothing will be done except return 0. However, we should check whether IO part support wider bus or not. We should use available IO ability if supported. In addition, there's a duplicated check to MMC_CAP_4_BIT_DATA since sdio_enable_wide() will include that check. And we can also save one call site to sdio_enable_wide() after this change.

2020-07-13mmc: core: Always allow the card detect uevent to be consumedUlf Hansson
The approach to allow userspace ~5s to consume the uevent, which is triggered when a new card is inserted/initialized, currently requires the mmc host to support system wakeup. This is unnecessary limiting, especially for an mmc host that relies on a GPIO IRQ for card detect. More precisely, the mmc host may not support system wakeup for its corresponding struct device, while the GPIO IRQ still could be configured as a wakeup IRQ via enable_irq_wake(). To support all various cases, let's simply drop the need for the wakeup support. Instead let's always register a wakeup source and activate it for all card detect IRQs by calling __pm_wakeup_event().
