2019-09-11mmc: mtk-sd: Re-store SDIO IRQs mask at system resumeUlf Hansson
In cases when SDIO IRQs have been enabled, runtime suspend is prevented by the driver. However, this still means msdc_runtime_suspend|resume() gets called during system suspend/resume, via pm_runtime_force_suspend|resume(). This means during system suspend/resume, the register context of the mtk-sd device most likely loses its register context, even in cases when SDIO IRQs have been enabled. To re-enable the SDIO IRQs during system resume, the mtk-sd driver currently relies on the mmc core to re-enable the SDIO IRQs when it resumes the SDIO card, but this isn't the recommended solution. Instead, it's better to deal with this locally in the mtk-sd driver, so let's do that. Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>

2019-09-11mmc: sdhci: Fix incorrect switch to HS modeAl Cooper
When switching from any MMC speed mode that requires 1.8v (HS200, HS400 and HS400ES) to High Speed (HS) mode, the system ends up configured for SDR12 with a 50MHz clock which is an illegal mode. This happens because the SDHCI_CTRL_VDD_180 bit in the SDHCI_HOST_CONTROL2 register is left set and when this bit is set, the speed mode is controlled by the SDHCI_CTRL_UHS field in the SDHCI_HOST_CONTROL2 register. The SDHCI_CTRL_UHS field will end up being set to 0 (SDR12) by sdhci_set_uhs_signaling() because there is no UHS mode being set. The fix is to change sdhci_set_uhs_signaling() to set the SDHCI_CTRL_UHS field to SDR25 (which is the same as HS) for any switch to HS mode. This was found on a new eMMC controller that does strict checking of the speed mode and the corresponding clock rate. It caused the switch to HS400 mode to fail because part of the sequence to switch to HS400 requires a switch from HS200 to HS before going to HS400.

The datasheet of the IP (sd4hc) says it is compiatible with SDHCI v4, but the spec version field in the version register is read as 2 (i.e. SDHCI_SPEC_300) based on the RTL provided by Cadence. Socionext did not fix it up when it integrated the IP into the SoCs. So, it is working as SDHCI v3. It is not a real problem because there is no difference in the program flow in sdhci.c between SDHCI_SPEC_300/400, but set the real version just in case.

2019-09-11mmc: sdhci-of-aspeed: Add support for the ASPEED SD controllerAndrew Jeffery
Add a minimal driver for ASPEED's SD controller, which exposes two SDHCIs. The ASPEED design implements a common register set for the SDHCIs, and moves some of the standard configuration elements out to this common area (e.g. 8-bit mode, and card detect configuration which is not currently supported). The SD controller has a dedicated hardware interrupt that is shared between the slots. The common register set exposes information on which slot triggered the interrupt; early revisions of the patch introduced an irqchip for the register, but reality is it doesn't behave as an irqchip, and the result fits awkwardly into the irqchip APIs. Instead I've taken the simple approach of using the IRQ as a shared IRQ with some minor performance impact for the second slot. Ryan was the original author of the patch - I've taken his work and massaged it to drop the irqchip support and rework the devicetree integration. The driver has been smoke tested under qemu against a minimal SD controller model and lightly tested on an ast2500-evb.

2019-09-11mmc: sdhci-cadence: use struct_size() helperGustavo A. R. Silva
One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct sdhci_cdns_priv { ... struct sdhci_cdns_phy_param phy_params[0]; }; Make use of the struct_size() helper instead of an open-coded version in order to avoid any potential type mistakes. So, replace the following form: sizeof(*priv) + sizeof(priv->phy_params[0]) * nr_phy_params with: struct_size(priv, phy_params, nr_phy_params) Also, notice that, in this case, variable priv_size is not necessary, hence it is removed.
