The QEMU open source machine emulator and virtualizer presents firmware and operating systems running in virtual machines ("guests") with purely virtual hardware (ie. hardware that has never existed in physical form). Since QEMU exposes some of these devices in a DTB, it makes sense to define "qemu" and "virtio" as vendor prefixes. The qemu definition is from [1], revision 4451 (22:24, 25 November 2014). The virtio definition is composed from [2] and [3].

2015-01-13of: replace Asahi Kasei Corp vendor prefixKuninori Morimoto
Current vendor-prefixes.txt already has "ak" prefix for Asahi Kasei Corp by ae8c4209af2c(of: Add vendor prefix for Asahi Kasei Corp.) It went through the appropriate review process. But, almost all Asahi Kasei chip drivers are using "asahi-kasei" prefix today. (arch/arm/boot/dts/tegra20-seaboard.dts only is using "ak,ak8975", but there are instances of "asahi-kasei,ak8975" in other dts files. And drivers/iio/magnetometer/ak8975.c doesn't support "ak,ak8975" prefix) So, we made a mistake there. In addition, checkpatch.pl reports WARNING if it is using "asahi-kasei" prerfix in DT file. (DT compatible string vendor "asahi-kasei" appears un-documented) Marking it deprecated and warning with checkpatch is certainly preferable. So, this patch replace "ak" to "asahi-kasei" in vendor-prefixes.txt. (and fixup tegra20-seaboard) OTOH, Asahi Kasei is usually referred to as "AKM", but this patch doesn't care about it. Because no DT is using that today.

2015-01-13i2c: rk3x: Account for repeated start time requirementDoug Anderson
On Rockchip I2C the controller drops SDA low slightly too soon to meet the "repeated start" requirements. >From my own experimentation over a number of rates: - controller appears to drop SDA at .875x (7/8) programmed clk high. - controller appears to keep SCL high for 2x programmed clk high. The first rule isn't enough to meet tSU;STA requirements in Standard-mode on the system I tested on. The second rule is probably enough to meet tHD;STA requirements in nearly all cases (especially after accounting for the first), but it doesn't hurt to account for it anyway just in case. Even though the repeated start requirement only need to be accounted for during a small part of the transfer, we'll adjust the timings for the whole transfer to meet it. I believe that adjusting the timings in just the right place to switch things up for repeated start would require several extra interrupts and that doesn't seem terribly worth it. With this change and worst case rise/fall times, I see 100kHz i2c going to ~85kHz. With slightly optimized rise/fall (800ns / 50ns) I see i2c going to ~89kHz. Fast-mode isn't affected much because tSU;STA is shorter relative to tHD;STA there. As part of this change we needed to account for the SDA falling time. The specification indicates that this should be the same, but we'll follow Designware's lead and add a binding. Note that we deviate from Designware and assign the default SDA falling time to be the same as the SCL falling time, which is incredibly likely.

2015-01-13i2c: rk3x: fix bug that cause measured high_ns doesn't meet I2C specificationaddy ke
The number of clock cycles to be written into the CLKDIV register that determines the I2C clk high phase includes the rise time. So to meet the timing requirements defined in the I2C specification which defines the minimal time SCL has to be high, the rise time has to taken into account. The same applies to the low phase with falling time. In my test on RK3288-Pink2 board, which is not an upstream board yet, if external pull-up resistor is 4.7K, rise_ns is about 700ns. So the measured high_ns is about 3900ns, which is less than 4000ns (the minimum high_ns in I2C specification for Standard-mode). To fix this bug min_low_ns should include fall time and min_high_ns should include rise time. This patch merged the patch from chromium project which can get the rise and fall times for signals from the device tree. This allows us to more accurately calculate timings. see: https://chromium-review.googlesource.com/#/c/232774/ Signed-off-by: Addy Ke <addy.ke@rock-chips.com> Reviewed-by: Doug Anderson <dianders@chromium.org> Tested-by: Doug Anderson <dianders@chromium.org> [wsa: fixed a typo in the docs] Signed-off-by: Wolfram Sang <wsa@the-dreams.de>

2015-01-13PM / Domains: Add DT bindings for the R-Mobile System ControllerGeert Uytterhoeven
The Renesas R-Mobile System Controller provides a.o. power management support, following the generic PM domain bindings in Documentation/devicetree/bindings/power/power_domain.txt. For now this supports the R-Mobile A1 (r8a7740) only, but it should be sufficiently generic to handle other members of the SH-Mobile/R-Mobile family in the future.

2015-01-12drm/i915: Move to atomic plane helpers (v9)Matt Roper
Switch plane handling to use the atomic plane helpers. This means that rather than provide our own implementations of .update_plane() and .disable_plane(), we expose the lower-level check/prepare/commit/cleanup entrypoints and let the DRM core implement update/disable for us using those entrypoints. The other main change that falls out of this patch is that our drm_plane's will now always have a valid plane->state that contains the relevant plane state (initial state is allocated at plane creation). The base drm_plane_state pointed to holds the requested source/dest coordinates, and the subclassed intel_plane_state holds the adjusted values that our driver actually uses. v2: - Renamed file from intel_atomic.c to intel_atomic_plane.c (Daniel) - Fix a copy/paste comment mistake (Bob) v3: - Use prepare/cleanup functions that we've already factored out - Use newly refactored pre_commit/commit/post_commit to avoid sleeping during vblank evasion v4: - Rebase to latest di-nightly requires adding an 'old_state' parameter to atomic_update; v5: - Must have botched a rebase somewhere and lost some work. Restore state 'dirty' flag to let begin/end code know which planes to run the pre_commit/post_commit hooks for. This would have actually shown up as broken in the next commit rather than this one. v6: - Squash kerneldoc patch into this one. - Previous patches have now already taken care of most of the infrastructure that used to be in this patch. All we're adding here now is some thin wrappers. v7: - Check return of intel_plane_duplicate_state() for allocation failures. v8: - Drop unused drm_plane_state -> intel_plane_state cast. (Ander) - Squash in actual transition to plane helpers. Significant refactoring earlier in the patchset has made the combined prep+transition much easier to swallow than it was in earlier iterations. (Ander) v9: - s/track_fbs/disabled_planes/ in the atomic crtc flags. The only fb's we need to update frontbuffer tracking for are those on a plane about to be disabled (since the atomic helpers never call prepare_fb() when disabling a plane), so the new name more accurately describes what we're actually tracking.
