2018-11-05drm/i915/icl: Configure MG PHY gating for HDMI ports tooImre Deak3-68/+70
The MG PHY clock gating needs to be configured for Type C static/fixed/legacy HDMI ports the same way it's configured for Type C static/fixed/legacy and aternate mode DP ports, fix this.

2018-11-05drm/vgem: create a render node for vgemEmil Velikov1-1/+2
VGEM doesn't do anything modeset specific, so in a way exposing a primary node is 'wrong'. At the same time, we extensively use if for creating dumb buffers, fences, prime fd <> handle imports/exports. To the point that we explicitly annotate the vgem fence ioctls as DRM_RENDER_ALLOW and have an IGT test which opens the render node. close(drm_open_driver_render(DRIVER_VGEM)) Better late than never, let's flip the switch.

2018-11-05drm/sun4i: Add support for H6 HDMI PHYJernej Skrabec1-0/+137
H6 has Synopsys DWC HDMI 2.0 TX PHY. There is no freely available documentation for it, only code found in BSP kernel. However, judging by the code, PHY is very similar to older Synopsys HDMI PHY described in i.MX6 documentation. Most registers seem to be the same. According to i.MX6 documentation, mpll settings are based on pixel clock and are not specific to each SoC. Because of that, mpll table in this commit is based on that documentation and not on BSP code. Other PHY settings were derived from BSP PHY driver code.

2018-11-05drm/sun4i: Add support for Synopsys HDMI PHYJernej Skrabec3-6/+24
Currently sun8i-hdmi-phy driver supports only custom PHYs connected to DW HDMI controller. Since newest Allwinner SoCs have unmodified Synopsys PHY, driver has to be reorganized to support them. Variant structure is expanded to allow differentiation between custom and Sysnopsys PHYs and to hold Synopsys PHY settings. Since DW HDMI bridge platform data has different fields for custom and Sysnopsys PHY, function sun8i_hdmi_phy_get_ops() is replaced with sun8i_hdmi_phy_set_ops().

2018-11-05mtd: docg3: don't set conflicting BCH_CONST_PARAMS optionArnd Bergmann1-1/+1
I noticed during the creation of another bugfix that the BCH_CONST_PARAMS option that is set by DOCG3 breaks setting variable parameters for any other users of the BCH library code. The only other user we have today is the MTD_NAND software BCH implementation (most flash controllers use hardware BCH these days and are not affected). I considered removing BCH_CONST_PARAMS entirely because of the inherent conflict, but according to the description in lib/bch.c there is a significant performance benefit in keeping it. To avoid the immediate problem of the conflict between MTD_NAND_BCH and DOCG3, this only sets the constant parameters if MTD_NAND_BCH is disabled, which should fix the problem for all cases that are affected. This should also work for all stable kernels. Note that there is only one machine that actually seems to use the DOCG3 driver (arch/arm/mach-pxa/mioa701.c), so most users should have the driver disabled, but it almost certainly shows up if we wanted to test random kernels on machines that use software BCH in MTD.

2018-11-05Revert "drm/exynos/decon5433: implement frame counter"Inki Dae3-21/+0
This reverts commit 0586feba322e1de05075700eb4b835c8b683e62b This patch makes it to need get_vblank_counter callback in crtc to get frame counter from decon driver. However, drm_dev->max_vblank_count is a member unique to vendor's DRM driver but in case of ARM DRM, some CRTC devices don't provide the frame counter value. As a result, this patch made extension and clone mode not working. Instead of this patch, we may need separated max_vblank_count which belongs to each CRTC device, or need to implement frame counter emulation for them who don't support HW frame counter.

2018-11-04bonding/802.3ad: fix link_failure_count trackingJarod Wilson1-2/+2
Commit 4d2c0cda07448ea6980f00102dc3964eb25e241c set slave->link to BOND_LINK_DOWN for 802.3ad bonds whenever invalid speed/duplex values were read, to fix a problem with slaves getting into weird states, but in the process, broke tracking of link failures, as going straight to BOND_LINK_DOWN when a link is indeed down (cable pulled, switch rebooted) means we broke out of bond_miimon_inspect()'s BOND_LINK_DOWN case because !link_state was already true, we never incremented commit, and never got a chance to call bond_miimon_commit(), where slave->link_failure_count would be incremented. I believe the simple fix here is to mark the slave as BOND_LINK_FAIL, and let bond_miimon_inspect() transition the link from _FAIL to either _UP or _DOWN, and in the latter case, we now get proper incrementing of link_failure_count again.

Add support for platforms where pit_shutdown() doesn't work because of a quirk in the PIT emulation. On these platforms setting the counter register to zero causes the PIT to start running again, negating the shutdown. Provide a global variable that controls whether the counter register is zero'ed, which platform specific code can override.
