2020-01-20mmc: sdhci-of-esdhc: fix transfer mode register readingYangbo Lu
The standard SD controller uses two 16-bit registers for command sending. 0xC: Transfer Mode Register 0xE: Command Register But the eSDHC controller uses one 32-bit register instead. 0xC: XFERTYPE For Transfer Mode Register and Command Register writing, the eSDHC driver will store Transfer Mode Register value in a variable first. When Command Register writing happens, driver will directly write a 32-bit value into XFERTYPE register. But for Transfer Mode Register reading, driver just returns a actual value. This may cause issue for some read-modify-write operations. We should make both reading and write on that variable for Transfer Mode Register.

2020-01-20mmc: sdhci-brcmstb: 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. This issue was previously fixed by commit c894e33ddc191 ("mmc: sdhci: Fix incorrect switch to HS mode") and later removed by commit 07bcc411567c ("Revert \"mmc: sdhci: Fix incorrect switch to HS mode\"") because it caused failures with some SD cards on AM65X systems. The fix will now be done in a platform specific callback instead of common sdhci code.

2020-01-20mmc: sdhci-brcmstb: Add ability to use HS400ES transfer modeAl Cooper
The latest eMMC JEDEC specification version 5.1 added a new transfer mode, HS400 with enhanced strobe (HS400ES). This mode will be selected if both the host controller and eMMC device support it. The latest Arasan 5.1 controller in the 7216a0 supports this mode. The "Host Controller Specification" has not been updated so the controller register bit used to enable this mode is not specified and varies the with controller vendor. The Linux SDHCI driver supplies a callback for enabling HS400ES mode and that callback will be used to supply a routine that will set the proper bit in the Arasan Vendor register.

2020-01-20ALSA: hda: Apply aligned MMIO access only conditionallyTakashi Iwai
It turned out that the recent simplification of HD-audio bus access helpers caused a regression on the virtual HD-audio device on QEMU with ARM platforms. The driver got a CORB/RIRB timeout and couldn't probe any codecs. The essential difference that caused a problem was the enforced aligned MMIO accesses by simplification. Since snd-hda-tegra driver is enabled on ARM, it enables CONFIG_SND_HDA_ALIGNED_MMIO, which makes the all HD-audio drivers using the aligned MMIO accesses. While this is mandatory for snd-hda-tegra, it seems that snd-hda-intel on ARM gets broken by this access pattern. For addressing the regression, this patch introduces a new flag, aligned_mmio, to hdac_bus object, and applies the aligned MMIO only when this flag is set. This change affects only platforms with CONFIG_SND_HDA_ALIGNED_MMIO set, i.e. mostly only for ARM platforms. Unfortunately the patch became a big bigger than it should be, just because the former calls didn't take hdac_bus object in the argument, hence we had to extend the call patterns.

When checking whether the reported lfb_size makes sense, the height * stride result is page-aligned before seeing whether it exceeds the reported size. This doesn't work if height * stride is not an exact number of pages. For example, as reported in the kernel bugzilla below, an 800x600x32 EFI framebuffer gets skipped because of this.

2020-01-20net: phy: don't crash in phy_read/_write_mmd without a PHY driverAlex Marginean
The APIs can be used by Ethernet drivers without actually loading a PHY driver. This may become more widespread in the future with 802.3z compatible MAC PCS devices being locally driven by the MAC driver when configuring for a PHY mode with in-band negotiation. Check that drv is not NULL before reading from it. Signed-off-by: Alex Marginean <alexandru.marginean@nxp.com> Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Signed-off-by: David S.

2020-01-20net: phylink: Allow 2.5BASE-T, 5GBASE-T and 10GBASE-T for the 10G link modesVladimir Oltean
For some reason, PHYLINK does not put the copper modes for 802.3bz (NBASE-T) and 802.3an-2006 (10GBASE-T) in the PHY's supported mask, when the PHY-MAC connection is a 10G-capable one (10GBase-KR, 10GBase-R, USXGMII). One possible way through which the cable side can work at the lower speed is by having the PHY emit PAUSE frames towards the MAC. So fix that omission. Also include the 2500Base-X fiber mode in this list while we're at it. Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2020-01-20net: ip6_gre: fix moving ip6gre between namespacesNiko Kortstrom
Support for moving IPv4 GRE tunnels between namespaces was added in commit b57708add314 ("gre: add x-netns support"). The respective change for IPv6 tunnels, commit 22f08069e8b4 ("ip6gre: add x-netns support") did not drop NETIF_F_NETNS_LOCAL flag so moving them from one netns to another is still denied in IPv6 case. Drop NETIF_F_NETNS_LOCAL flag from ip6gre tunnels to allow moving ip6gre tunnel endpoints between network namespaces.

2020-01-20net: stmmac: modified pcs mode support for RGMIIDejin Zheng
snps databook noted that physical coding sublayer (PCS) interface that can be used when the MAC is configured for the TBI, RTBI, or SGMII PHY interface. we have RGMII and SGMII in a SoC and it also has the PCS block. it needs stmmac_init_phy and stmmac_mdio_register function for initializing phy when it used RGMII interface.

2020-01-20cpufreq: brcmstb-avs: fix imbalance of cpufreq policy refcountchenqiwu
brcm_avs_cpufreq_get() calls cpufreq_cpu_get() to get the cpufreq policy, meanwhile, it also increments the kobject reference count to mark it busy. However, a corresponding call of cpufreq_cpu_put() is ignored to decrement the kobject reference count back, which may lead to a potential stuck risk that the cpuhp thread deadly waits for dropping of kobject refcount when cpufreq policy free. With this patch, the cpuhp thread can be easily exercised by attempting to force an unbind of the CPUfreq driver.
