2016-07-25Documentation: phy: Let the rockchip eMMC PHY get an exported card clockDouglas Anderson
As of an earlier change in this series ("Documentation: mmc: sdhci-of-arasan: Add ability to export card clock") the SDHCI driver used on Rockchip SoCs can now expose its clock. Let's now specify that the PHY can use it. Letting the PHY get access to this clock means it can adjust phyctrl_frqsel field appropriately. Although the Rockchip PHY appears slightly different than the reference Arasan one, you can see that the Arasan datasheet [1] had it defined as: Select the frequency range of DLL operation: 3b'000 => 200MHz to 170 MHz 3b'001 => 170MHz to 140 MHz 3b'010 => 140MHz to 110 MHz 3b'011 => 110MHz to 80MHz 3b'100 => 80MHz to 50 MHz 3b'101 => 275Mhz to 250MHz 3b'110 => 250MHz to 225MHz 3b'111 => 225MHz to 200MHz On the Rockchip version of the PHY we have less granularity but the idea is the same.

2016-07-25mmc: sdhci-of-arasan: Add ability to export card clockDouglas Anderson
Some SD/eMMC PHYs (like the PHY from Arasan that is designed to work with arasan,sdhci-5.1) need to know the card clock in order to function properly. Let's add the ability to expose this clock. Any PHY that needs to know the clock rate can add a reference and query the clock rate. At the moment we register a CLK_GET_RATE_NOCACHE clock that simply allows querying the clock. This allows us to be less intrusive with regards to the main SDHCI driver, which has complex logic for adjusting the SD clock. Right now we always fully power cycle the PHY when the clock changes and that gives the PHY a good chance to query our clock.

2016-07-25mmc: sdhci-of-arasan: Properly set corecfg_baseclkfreq on rk3399Douglas Anderson
In the the earlier change in this series ("Documentation: mmc: sdhci-of-arasan: Add soc-ctl-syscon for corecfg regs") we can see the mechansim for specifying a syscon to properly set corecfg registers in sdhci-of-arasan. Now let's use this mechanism to properly set corecfg_baseclkfreq on rk3399. >From [1] the corecfg_baseclkfreq is supposed to be set to: Base Clock Frequency for SD Clock. This is the frequency of the xin_clk. This is a relatively easy thing to do. Note that we assume that xin_clk is not dynamic and we can check the clock at probe time. If any real devices have a dynamic xin_clk future patches could register for notifiers for the clock. At the moment, setting corecfg_baseclkfreq is only supported for rk3399 since we need a specific map for each implementation. The code is written in a generic way that should make this easy to extend to other SoCs. Note that a specific compatible string for rk3399 is already in use and so we add that to the table to match rk3399.

2016-07-25Documentation: mmc: sdhci-of-arasan: Add soc-ctl-syscon for corecfg regsDouglas Anderson
As can be seen in Arasan's datasheet [1] there are several "corecfg" settings in their SDHCI IP Block that are supposed to be controlled by software. Although the datasheet referenced is a bit vague about how to access corecfg, in Figure 5 you can see that for Arasan's PHY (a separate component than their SDHCI component) they describe the "phyctrl" registers as being "FROM SOC CTL REG", implying that it's up to the licensee of the Arasan IP block to implement these registers. It seems sane to assume that the "corecfg" registers in their SDHCI IP block works in a similar way for all licensees of the IP Block. Device tree has a model that allows a device to get a reference to random registers located elsewhere in the SoC: sysctl. Let's leverage this model and allow adding a sysctl reference to access the control registers for the Arasan SDHCI PHYs. Having a reference to the control registers doesn't do much for us on its own since the Arasan spec doesn't specify how these corecfg values are laid out in memory. In the SDHCI driver we'll need a map detailing where each corecfg can be found in each implementation. This map can be found using the primary compatible string of the SDHCI device. In that spirit, document that existing rk3399 device trees already have a specific compatible string, though up to now they've always been relying on the driver supporting the generic. Note that since existing devices seem to work fairly well as-is, we'll list the syscon reference as "optional", but it's likely that we'll run into much fewer problems if we can actually set the proper values in the syscon, so it is strongly suggested that any SoCs where we have a map to set the corecfg also include a reference to the syscon.

2016-07-25mmc: sdhci-of-arasan: Always power the PHY off/on when clock changesDouglas Anderson
In commit 802ac39a5566 ("mmc: sdhci-of-arasan: fix set_clock when a phy is supported") we added code to power the PHY off and on whenever the clock was changed but we avoided doing the power cycle code when the clock was low speed. Let's now do it always. Although there may be other reasons for power cycling the PHY when the clock changes, one of the main reasons is that we need to give the DLL a chance to re-lock with the new clock. One of the things that the DLL is for is tuning the Receive Clock in HS200 mode and STRB in HS400 mode. Thus it is clear that we should make sure we power cycle the PHY (and wait for the DLL to lock) when we know we'll be in one of these two speed modes. That's what the original code did, though it used the clock rate rather than the speed mode. However, even in speed modes other than HS200,/HS400 the DLL is used for something since it can be clearly observed that the PHY doesn't function properly if you leave the DLL off. Although it appears less important to power cycle the PHY and wait for the DLL to lock when not in HS200/HS400 modes (no bugs were reported), it still seems wise to let the locking always happen nevertheless. Note: as part of this, we make sure that we never try to turn the PHY on when the clock is off (when the clock rate is 0). The PHY cannot work when the clock is off since its DLL can't lock. This change requires ("phy: rockchip-emmc: Increase lock time allowance") and will cause problems if picked without that change.

2016-07-25phy: rockchip-emmc: Increase lock time allowanceDouglas Anderson
Previous PHY code waited a fixed amount of time for the DLL to lock at power on time. Unfortunately, the time for the DLL to lock is actually a bit more dynamic and can be longer if the card clock is slower. Instead of waiting a fixed 30 us, let's now dynamically wait until the lock bit gets set. We'll wait up to 10 ms which should be OK even if the card clock is at the super slow 100 kHz. On its own, this change makes the PHY power on code a little more robust. Before this change the PHY was relying on the eMMC code to make sure the PHY was only powered on when the card clock was set to at least 50 MHz before, though this reliance wasn't documented anywhere. This change will be even more useful in future changes where we actually need to be able to wait for a DLL lock at slower clock speeds.

The output tap delay controls helps maintain the hold requirements for eMMC. The exact value is dependent on the SoC and other factors, though it isn't really an exact science. But the default of 0 is not very good, as it doesn't give the eMMC much hold time, so let's bump up to 4 (approx 90 degree phase?). If we need to configure this any further (e.g., based on board or speed factors), we may need to consider a device tree representation.

It also ignores possibilities: - data lines 1-3 are not connected and could show at any level - data lines 1-2 can be used by SDIO for other purposes According to the SD specification, it is OK to check any of the data lines for voltage switching, so change to use DAT[0] only.

git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security Pull key handling fixes from James Morris: "Quoting David Howells: Here are three miscellaneous fixes: (1) Fix a panic in some debugging code in PKCS#7. This can only happen by explicitly inserting a #define DEBUG into the code. (2) Fix the calculation of the digest length in the PE file parser. This causes a failure where there should be a success. (3) Fix the case where an X.509 cert can be added as an asymmetric key to a trusted keyring with no trust restriction if no AKID is supplied. Bugs (1) and (2) aren't particularly problematic, but (3) allows a security check to be bypassed. Happily, this is a recent regression and never made it into a released kernel" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security: KEYS: Fix for erroneous trust of incorrectly signed X.509 certs pefile: Fix the failure of calculation for digest PKCS#7: Fix panic when referring to the empty AKID when DEBUG defined

git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm Pull libnvdimm fix from Dan Williams: "This contains a regression fix for a problem that was introduced in v4.7-rc6. In 4.7-rc1 we introduced auto-probing for the ACPI DSM (device- specific-method) format that the platform firmware implements for nvdimm devices. We initially fixed a regression in probing the QEMU DSM implementation by making acpi_check_dsm() tolerant of the way QEMU reports the "0 DSMs supported" condition. However, that broke HPE platforms since that tolerance caused the driver to mistakenly match the 1-zero-byte response those platforms give to "unknown" commands. Instead, we simply make the driver tolerant of not finding any supported DSMs. This has been tested to work with both QEMU and HPE platforms. This commit has appeared in a -next release with no reported issues" * 'libnvdimm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: nfit: make DIMM DSMs optional
