2020-11-16mmc: renesas_sdhi: merge the SCC reset functionsWolfram Sang
There is no user of renesas_sdhi_reset_scc() anymore, only renesas_sdhi_disable_scc() so merge these functions into one. I guess the seperation was cruft anyhow. The BSP doesn't have it anymore and I can't recall the reason we had it.

2020-11-16mmc: renesas_sdhi: populate SCC pointer at the proper placeWolfram Sang
The SCC pointer is currently filled whenever the SoC is Gen2+. This is wrong because there is a Gen2-variant without SCC (SDHI_VER_GEN2_SDR50). We have been lucky because the writes to unintended registers have not caused problems so far. But further refactoring work exposed the problem. So, move the pointer initialization to the place where we know that the SDHI instance supports tuning. And also populate the 'reset' pointer unconditionally to make sure the interrupt enable register is always properly set for Gen2+.

2020-11-16mmc: core: Initial support for SD express card/hostUlf Hansson
In the SD specification v7.10 the SD express card has been added. This new type of removable SD card, can be managed via a PCIe/NVMe based interface, while also allowing backwards compatibility towards the legacy SD interface. To keep the backwards compatibility, it's required to start the initialization through the legacy SD interface. If it turns out that the mmc host and the SD card, both supports the PCIe/NVMe interface, then a switch should be allowed. Therefore, let's introduce some basic support for this type of SD cards to the mmc core. The mmc host, should set MMC_CAP2_SD_EXP if it supports this interface and MMC_CAP2_SD_EXP_1_2V, if also 1.2V is supported, as to inform the core about it. To deal with the switch to the PCIe/NVMe interface, the mmc host is required to implement a new host ops, ->init_sd_express(). Based on the initial communication between the host and the card, host->ios.timing is set to either MMC_TIMING_SD_EXP or MMC_TIMING_SD_EXP_1_2V, depending on if 1.2V is supported or not. In this way, the mmc host can check these values in its ->init_sd_express() ops, to know how to proceed with the handover. Note that, to manage card insert/removal, the mmc core sticks with using the ->get_cd() callback, which means it's the host's responsibility to make sure it provides valid data, even if the card may be managed by PCIe/NVMe at the moment. As long as the card seems to be present, the mmc core keeps the card powered on.

2020-11-16mmc: sdhci-acpi: AMDI0040: Allow changing HS200/HS400 driver strengthRaul E Rangel
This change will allow platform designers better control over signal integrity by allowing them to tune the HS200 and HS400 driver strengths. The driver strength was previously hard coded to A to solve boot problems with certain platforms. This driver strength does not universally apply to all platforms so we need a knob to adjust it. All older platforms currently have the SDR104 preset hard coded to A in the firmware. This means that switching from the hard coded value in the kernel to reading the SDR104 preset is a no-op for these platforms. Newer platforms will have properly set presets. So this change will support both new and old platforms.

2020-11-15kvm: mmu: fix is_tdp_mmu_check when the TDP MMU is not in usePaolo Bonzini
In some cases where shadow paging is in use, the root page will be either mmu->pae_root or vcpu->arch.mmu->lm_root. Then it will not have an associated struct kvm_mmu_page, because it is allocated with alloc_page instead of kvm_mmu_alloc_page. Just return false quickly from is_tdp_mmu_root if the TDP MMU is not in use, which also includes the case where shadow paging is enabled. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
