Each of hdmi and edp are already attached in msm_*_bridge_init. A second
attachment returns -EBUSY, failing the driver load.
Tested with HDMI on IFC6410 (APQ8064 / MDP4), but eDP case should be
analogous.

Move mapping of resources to encoder ids from the resource manager to a
new dpu_global_state struct. Store this struct in global atomic state.
Before this patch, atomic test would be performed by modifying global
state (resource manager), and backing out any changes if the test fails.
By using drm atomic global state, this is not necessary as any changes
to the global state will be discarded if the test fails.

Track hardware resource objects in arrays rather than
a list and remove the resource manager's iterator idiom. Separate
the mapping of hardware resources to an encoder ID into a different
array.
Use an implicit mapping between the hardware blocks' ids, which
are 1-based, and array indices in these arrays to replace iteration
with index lookups in several places.

For a given byte clock, if VCO recalc value is exactly same as
vco set rate value, vco_set_rate does not get called assuming
VCO is already set to required value. But Due to GDSC toggle,
VCO values are erased in the HW. To make sure VCO is programmed

Commit e812744c5f ("drm: msm: a6xx: Add support for A618") added a
universal GBIF un-halt into a6xx_start(). This can cause problems for
a630 targets which do not use GBIF and might have access protection
enabled on the region now occupied by the GBIF registers.
But it turns out that we didn't need to unhalt the GBIF in this path
since the stop function already takes care of that after executing a flush
but before turning off the headswitch. We should be confident that the
GBIF is open for business when we restart the hardware.

I was hitting kCFI crashes when building with clang, and after
some digging finally narrowed it down to the
dsi_mgr_connector_mode_valid() function being implemented as
returning an int, instead of an enum drm_mode_status.
This patch fixes it, and appeases the opaque word of the kCFI
gods (seriously, clang inlining everything makes the kCFI
backtraces only really rough estimates of where things went
wrong).
Thanks as always to Sami for his help narrowing this down.

the normal collection of driver updates to support new SoCs, fix incorrect
data, and convert various drivers to clk_hw based APIs.
In the core, we allow clk_ops::init() to return an error code now so that we
can fail clk registration if the callback does something like fail to allocate
memory. We also add a new "terminate" clk_op so that things done in
clk_ops::init() can be undone, e.g. free memory. We also spit out a warning now
when critical clks fail to enable and we support changing clk rates and
enable/disable state through debugfs when developers compile the kernel
themselves.
On the driver front, we get support for what seems like a lot of Qualcomm and
NXP SoCs given that those vendors dominate the diffstat. There are a couple new
drivers for Xilinx and Amlogic SoCs too. The updates are all small things like
fixing the way glitch free muxes switch parents, avoiding div-by-zero problems,
or fixing data like parent names. See the updates section below for more
details.
Finally, the "basic" clk types have been converted to support specifying
parents with clk_hw pointers. This work includes an overhaul of the fixed-rate
clk type to be more modern by using clk_hw APIs.
Core:
- Let clk_ops::init() return an error code
- Add a clk_ops::terminate() callback to undo clk_ops::init()
- Warn about critical clks that fail to enable or prepare
- Support dangerous debugfs actions on clks with dead code
New Drivers:
- Support for Xilinx Versal platform clks
- Display clk controller on qcom sc7180
- Video clk controller on qcom sc7180
- Graphics clk controller on qcom sc7180
- CPU PLLs for qcom msm8916
- Move qcom msm8974 gfx3d clk to RPM control
- Display port clk support on qcom sdm845 SoCs
- Global clk controller on qcom ipq6018
- Add a driver for BCLK of Freescale SAI cores
- Add cam, vpe and sgx clock support for TI dra7
- Add aess clock support for TI omap5
- Enable clks for CPUfreq on Allwinner A64 SoCs
- Add Amlogic meson8b DDR clock controller
- Add input clocks to Amlogic meson8b controllers
- Add SPIBSC (SPI FLASH) clock on Renesas RZ/A2
- i.MX8MP clk driver support
Updates:
- Convert gpio, fixed-factor, mux, gate, divider basic clks to hw based APIs
- Detect more PRMCU variants in ux500 driver
- Adjust the composite clk type to new way of describing clk parents
- Fixes for clk controllers on qcom msm8998 SoCs

These are updates to device drivers and file systems that for some reason
or another were not included in the kernel in the previous y2038 series.
I've gone through all users of time_t again to make sure the kernel is
in a long-term maintainable state, replacing all remaining references
to time_t with safe alternatives.
Some related parts of the series were picked up into the nfsd, xfs,
alsa and v4l2 trees. A final set of patches in linux-mm removes the now
unused time_t/timeval/timespec types and helper functions after all five
branches are merged for linux-5.6, ensuring that no new users get merged.
As a result, linux-5.6, or my backport of the patches to 5.4 [1], should
be the first release that can serve as a base for a 32-bit system designed
to run beyond year 2038, with a few remaining caveats:
- All user space must be compiled with a 64-bit time_t, which will be
supported in the coming musl-1.2 and glibc-2.32 releases, along with
installed kernel headers from linux-5.6 or higher.
- Applications that use the system call interfaces directly need to be
ported to use the time64 syscalls added in linux-5.1 in place of the
existing system calls. This impacts most users of futex() and seccomp()
as well as programming languages that have their own runtime environment
not based on libc.
- Applications that use a private copy of kernel uapi header files or
their contents may need to update to the linux-5.6 version, in
particular for sound/asound.h, xfs/xfs_fs.h, linux/input.h,
linux/elfcore.h, linux/sockios.h, linux/timex.h and linux/can/bcm.h.
- A few remaining interfaces cannot be changed to pass a 64-bit time_t
in a compatible way, so they must be configured to use CLOCK_MONOTONIC
times or (with a y2106 problem) unsigned 32-bit timestamps. Most
importantly this impacts all users of 'struct input_event'.
- All y2038 problems that are present on 64-bit machines also apply to
32-bit machines. In particular this affects file systems with on-disk
timestamps using signed 32-bit seconds: ext4 with ext3-style small
inodes, ext2, xfs (to be fixed soon) and ufs.
Changes since v1 [2]:
- Add Acks I received
- Rebase to v5.5-rc1, dropping patches that got merged already
- Add NFS, XFS and the final three patches from another series
- Rewrite etnaviv patches
- Add one late revert to avoid an etnaviv regression

With the db845c running AOSP, I see the following error on every
frame on the home screen:
[drm:dpu_plane_atomic_check:915] [dpu error]plane33 invalid src 2880x1620+0+470 line:2560
This is due to the error paths in atomic_check using
DPU_ERROR_PLANE(), and the drm_hwcomposer using atomic_check
to decide how to composite the frame (thus it expects to see
atomic_check to fail).
In order to avoid spamming the logs, this patch converts the
DPU_ERROR_PLANE() calls to DPU_DEBUG_PLANE() calls in
atomic_check.

has additional functionality introduced to enable/disable HS
signalling with default value set to enabled. To accommodate this
change, LANE_CTRL register should be read and bit wise ORed to enable

[cleanup subject / commit message]
Signed-off-by: Rob Clark <robdclark@chromium.org>
After commit fc0c209c14 ("clk: Allow parents to be specified without
string names") we can use DT or direct clk_hw pointers to specify
parents. Create a generic function that shouldn't be used very often to
encode the multitude of ways of registering a mux clk with different
parent information. Then add a bunch of wrapper macros that only pass
down what needs to be passed down to the generic function to support
this with less arguments.
Note: the msm drm driver passes an anonymous array through the macro
which seems to confuse my compiler. Adding a parenthesis around the
whole thing at the call site seems to fix it but it must be wrong. Maybe
it's better to split this patch and pick out the array bits there?
