| * drm: shmobile: Make DRM_SHMOBILE visible on Renesas SoC platformsGeert Uytterhoeven2023-05-241-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The LCD Controller supported by the drm-shmob driver is present on SuperH SH-Mobile SoCs, and on Renesas ARM SH/R-Mobile SoCs. Unfortunately its config option is not visible on either, so the user can never enable the support. Fix this by dropping the dependency on ARM (for SuperH), and by widening the dependency range to ARCH_RENESAS (for ARM).

| * drm/bridge: anx7625: Prevent endless probe loopNícolas F. R. A. Prado2023-05-231-40/+88
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During probe, the driver registers i2c dummy devices and populates the aux bus, which registers a device for the panel. After doing that, the driver can still defer probe if needed. This ordering of operations is troublesome however, because the deferred probe work will retry probing all pending devices every time a new device is registered. Therefore, if modules need to be loaded in order to satisfy the dependencies for this driver to complete probe, the kernel will stall, since it'll keep trying to probe the anx7625 driver, but never succeed, given that modules would only be loaded after the deferred probe work completes. Two changes are required to avoid this issue: * Move of_find_mipi_dsi_host_by_node(), which can defer probe, to before anx7625_register_i2c_dummy_clients() and devm_of_dp_aux_populate_ep_devices(), which register devices. * Make use of the done_probing callback when populating the aux bus, so that the bridge registration is only done after the panel is probed. This is required because the panel might need to defer probe, but the aux bus population needs the i2c dummy devices working, so this call couldn't just be moved to an earlier point in probe. One caveat is that if the panel is described outside the aux bus, the probe loop issue can still happen, but we don't have a way to avoid it in that case since there's no callback available. With this patch applied, it's possible to boot on mt8192-asurada-spherion with CONFIG_DRM_ANALOGIX_ANX7625=y CONFIG_MTK_MMSYS=m CONFIG_BACKLIGHT_PWM=y and also with CONFIG_DRM_ANALOGIX_ANX7625=y CONFIG_MTK_MMSYS=y CONFIG_BACKLIGHT_PWM=m Fixes: adca62ec370c ("drm/bridge: anx7625: Support reading edid through aux channel") Fixes: 269332997a16 ("drm/bridge: anx7625: Return -EPROBE_DEFER if the dsi host was not found") Reported-by: "kernelci.org bot" <bot@kernelci.org> Signed-off-by: Nícolas F.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rename drm_sched_wakeup() to drm_sched_wakeup_if_canqueue() since the former is misleading, as it wakes up the GPU scheduler _only if_ more jobs can be queued to the underlying hardware. This distinction is important to make, since the wake conditional in the GPU scheduler thread wakes up when other conditions are also true, e.g. when there are jobs to be cleaned. For instance, a user might want to wake up the scheduler only because there are more jobs to clean, but whether we can queue more jobs is irrelevant. v2: Separate "canqueue" to "can_queue". (Alex D.)

The common case has been the use of regular I/O functions, such as __raw_readb() or memset_io(). A few architectures used plain system- memory reads and writes. Sparc used helpers for its SBus. The architectures that used special cases provide the same code in their __raw_*() I/O helpers.

| * drivers/firmware: Move sysfb_init() from device_initcall to subsys_initcall_syncHuacai Chen2023-05-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Consider a configuration like this: 1, efifb (or simpledrm) is built-in; 2, a native display driver (such as radeon) is also built-in. As Javier said, this is not a common configuration (the native display driver is usually built as a module), but it can happen and cause some trouble. In this case, since efifb, radeon and sysfb are all in device_initcall() level, the order in practise is like this: efifb registered at first, but no "efi-framebuffer" device yet. radeon registered later, and /dev/fb0 created. sysfb_init() comes at last, it registers "efi-framebuffer" and then causes an error message "efifb: a framebuffer is already registered". Make sysfb_init() to be subsys_ initcall_sync() can avoid this. And Javier Martinez Canillas is trying to make a more general solution in commit 873eb3b11860 ("fbdev: Disable sysfb device registration when removing conflicting FBs"). However, this patch still makes sense because it can make the screen display as early as possible (We cannot move to subsys_initcall, since sysfb_init() should be executed after PCI enumeration).

| * drm: sun4i: calculate proper DCLK rate for DSIRoman Beranek2023-05-101-15/+21
| | | | | | | | | | | | | | | | | | In DSI mode, TCON0's data clock is required to run at 1/4 the per-lane bit rate. Signed-off-by: Roman Beranek <me@crly.cz> Signed-off-by: Maxime Ripard <maxime@cerno.tech> Link: https://patchwork.freedesktop.org/patch/msgid/20230505052110.67514-5-me@crly.cz
| * drm: sun4i: rename sun4i_dotclock to sun4i_tcon_dclkRoman Beranek2023-05-104-7/+7
| | | | | | | | | | | | | | | | | | | | | | While the rate of TCON0's DCLK matches dotclock for parallel and LVDS outputs, this doesn't hold for DSI. The 'D' in DCLK actually stands for 'Data' according to Allwinner's manuals. The clock is mostly referred to as dclk throughout this driver already anyway, so stick with that.
