Commit 358e76fd613a ("drm/sun4i: hdmi: Consolidate atomic_check and
mode_valid") changed the clock rate from an unsigned long to an unsigned
long long resulting in a a 64-bit division that might not be supported
on all platforms.

The resulted in compilation being broken at least for m68k, xtensa and
some arm configurations, at least.

Commit 358e76fd613a ("drm/sun4i: hdmi: Consolidate atomic_check and
mode_valid") added a call to drm_atomic_get_new_connector_state() but
didn't include drm_atomic.h which defines it.

On some configuration, this leads to a build failure, presumably because
in the common case the header gets included by an intermediate header
but it isn't always the case.

Let's add a proper include.

container_of_const() allows to preserve the pointer constness and is
thus more flexible than inline functions.

Let's switch all our instances of container_of() to container_of_const().

After removal of the legacy EEPROM driver and I2C_CLASS_DDC support in
olpc_dcon there's no i2c client driver left supporting I2C_CLASS_DDC.
Class-based device auto-detection is a legacy mechanism and shouldn't
be used in new code. So we can remove this class completely now.

drm-misc-next for v6.7-rc1:

UAPI Changes:
- drm_file owner is now updated during use, in the case of a drm fd
  opened by the display server for a client, the correct owner is
  displayed.
- Qaic gains support for the QAIC_DETACH_SLICE_BO ioctl to allow bo
  recycling.

Cross-subsystem Changes:
- Disable boot logo for au1200fb, mmpfb and unexport logo helpers.
  Only fbcon should manage display of logo.
- Update freescale in MAINTAINERS.
- Add some bridge files to bridge in MAINTAINERS.
- Update gma500 driver repo in MAINTAINERS to point to drm-misc.

Core Changes:
- Move size computations to drm buddy allocator.
- Make drm_atomic_helper_shutdown(NULL) a nop.
- Assorted small fixes in drm_debugfs, DP-MST payload addition error handling.
- Fix DRM_BRIDGE_ATTACH_NO_CONNECTOR handling.
- Handle bad (h/v)sync_end in EDID by clipping to htotal.
- Build GPUVM as a module.

Driver Changes:
- Simple drivers don't need to cache prepared result.
- Call drm_atomic_helper_shutdown() in shutdown/unbind for a whole lot
  more drm drivers.
- Assorted small fixes in amdgpu, ssd130x, bridge/it6621, accel/qaic,
  nouveau, tc358768.
- Add NV12 for komeda writeback.
- Add arbitration lost event to synopsis/dw-hdmi-cec.
- Speed up s/r in nouveau by not restoring some big bo's.
- Assorted nouveau display rework in preparation for GSP-RM,
  especially related to how the modeset sequence works and
  the DP sequence in relation to link training.
- Update anx7816 panel.
- Support NVSYNC and NHSYNC in tegra.
- Allow multiple power domains in simple driver.

<title>drm: Call drm_atomic_helper_shutdown() at shutdown time for misc drivers</title>
<updated>2023-09-21T17:41:04+00:00</updated>

<id>ce3d99c8349584bc0fbe1e21918a3ea1155343aa</id>
<content type='text'>
Based on grepping through the source code these drivers appear to be
missing a call to drm_atomic_helper_shutdown() at system shutdown
time. Among other things, this means that if a panel is in use that it
won't be cleanly powered off at system shutdown time.

The fact that we should call drm_atomic_helper_shutdown() in the case
of OS shutdown/restart comes straight out of the kernel doc "driver
instance overview" in drm_drv.c.

All of the drivers in this patch were fairly straightforward to fix
since they already had a call to drm_atomic_helper_shutdown() at
remove/unbind time but were just lacking one at system shutdown. The
only hitch is that some of these drivers use the component model to
register/unregister their DRM devices. The shutdown callback is part
of the original device. The typical solution here, based on how other
DRM drivers do this, is to keep track of whether the device is bound
based on drvdata. In most cases the drvdata is the drm_device, so we
can just make sure it is NULL when the device is not bound. In some
drivers, this required minor code changes. To make things simpler,
drm_atomic_helper_shutdown() has been modified to consider a NULL
drm_device as a noop in the patch ("drm/atomic-helper:
drm_atomic_helper_shutdown(NULL) should be a noop").

Based on grepping through the source code these drivers appear to be
missing a call to drm_atomic_helper_shutdown() at system shutdown
time. Among other things, this means that if a panel is in use that it
won't be cleanly powered off at system shutdown time.

The fact that we should call drm_atomic_helper_shutdown() in the case
of OS shutdown/restart comes straight out of the kernel doc "driver
instance overview" in drm_drv.c.

All of the drivers in this patch were fairly straightforward to fix
since they already had a call to drm_atomic_helper_shutdown() at
remove/unbind time but were just lacking one at system shutdown. The
only hitch is that some of these drivers use the component model to
register/unregister their DRM devices. The shutdown callback is part
of the original device. The typical solution here, based on how other
DRM drivers do this, is to keep track of whether the device is bound
based on drvdata. In most cases the drvdata is the drm_device, so we
can just make sure it is NULL when the device is not bound. In some
drivers, this required minor code changes. To make things simpler,
drm_atomic_helper_shutdown() has been modified to consider a NULL
drm_device as a noop in the patch ("drm/atomic-helper:
drm_atomic_helper_shutdown(NULL) should be a noop").

Pull clk subsystem updates from Stephen Boyd:
 "This pull request is full of clk driver changes. In fact, there aren't
  any changes to the clk framework this time around. That's probably
  because everyone was on vacation (yours truly included). We did lose a
  couple clk drivers this time around because nobody was using those
  devices. That skews the diffstat a bit, but either way, nothing looks
  out of the ordinary here. The usual suspects are chugging along adding
  support for more SoCs and fixing bugs.

  If I had to choose, I'd say the theme for the past few months has been
  "polish". There's quite a few patches that migrate to
  devm_platform_ioremap_resource() in here. And there's more than a
  handful of patches that move the NR_CLKS define from the DT binding
  header to the driver. There's even patches that migrate drivers to use
  clk_parent_data and clk_hw to describe clk tree topology. It seems
  that the spring (summer?) cleaning bug got some folks, or the
  semiconductor shortage finally hit the software side.

  New Drivers:
   - StarFive JH7110 SoC clock drivers
   - Qualcomm IPQ5018 Global Clock Controller driver
   - Versa3 clk generator to support 48KHz playback/record with audio
     codec on RZ/G2L SMARC EVK

  Removed Drivers:
   - Remove non-OF mmp clk drivers
   - Remove OXNAS clk driver

  Updates:
   - Add __counted_by to struct clk_hw_onecell_data and struct
     spmi_pmic_div_clk_cc
   - Move defines for numbers of clks (NR_CLKS) from DT headers to
     drivers
   - Introduce kstrdup_and_replace() and use it
   - Add PLL rates for Rockchip rk3568
   - Add the display clock tree for Rockchip rv1126
   - Add Audio Clock Generator (ADG) clocks on Renesas R-Car Gen3 and
     RZ/G2 SoCs
   - Convert sun9i-mmc clock to use
     devm_platform_get_and_ioremap_resource()
   - Fix function name in a comment in ccu_mmc_timing.c
   - Parameter name correction for ccu_nkm_round_rate()
   - Implement CLK_SET_RATE_PARENT for Allwinner NKM clocks, i.e.
     consider alternative parent rates when determining clock rates
   - Set CLK_SET_RATE_PARENT for Allwinner A64 pll-mipi
   - Support finding closest (as opposed to closest but not higher)
     clock rate for NM, NKM, mux and div type clocks, as use it for
     Allwinner A64 pll-video0
   - Prefer current parent rate if able to generate ideal clock rate for
     Allwinner NKM clocks
   - Clean up Qualcomm SMD RPM driver, with interconnect bus clocks
     moved out to the interconnect drivers
   - Fix various PM runtime bugs across many Qualcomm clk drivers
   - Migrate Qualcomm MDM9615 is to parent_hw and parent_data
   - Add network related resets on Qualcomm IPQ4019
   - Add a couple missing USB related clocks to Qualcomm IPQ9574
   - Add missing gpll0_sleep_clk_src to Qualcomm MSM8917 global clock
     controller
   - In the Qualcomm QDU1000 global clock controller, GDSCs, clkrefs,
     and GPLL1 are added, while PCIe pipe clock, SDCC rcg ops are
     corrected
   - Add missing GDSCs to and correct GDSCs for the SC8280XP global
     clock controller driver
   - Support retention for the Qualcomm SC8280XP display clock
     controller GDSCs.
   - Qualcommm's SDCC apps_clk_src is marked with CLK_OPS_PARENT_ENABLE
     to fix issues with missing parent clocks across sc7180, sm7150,
     sm6350 and sm8250, while sm8450 is corrected to use floor ops
   - Correct Qualcomm SM6350 GPU clock controller's clock supplies
   - Drop unwanted clocks from the Qualcomm IPQ5332 GCC driver
   - Add missing OXILICX GDSC to Qualcomm MSM8226 GCC
   - Change the delay in the Qualcomm reset controller to fsleep() for
     correctness
   - Extend the Qualcomm SM83550 Video clock controller to support
     SC8280XP
   - Add graphics clock support on Renesas RZ/G2M, RZ/G2N, RZ/G2E, and
     R-Car H3, M3-W, and M3-N SoCs
   - Add Clocked Serial Interface (CSI) clocks on Renesas RZ/V2M
   - Add PWM (MTU3) clock and reset on Renesas RZ/G2UL and RZ/Five
   - Add the PDM IPC clock for i.MX93
   - Add 519.75MHz frequency support for i.MX9 PLL
   - Simplify the .determine_rate() implementation for i.MX GPR mux

   - Drop the 393216000 and 361267200 from i.MX PLL14xx rate table to
     allow glitch free switching"
