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). Signed-off-by:

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: adca62ec ("drm/bridge: anx7625: Support reading edid through aux channel") Fixes: 26933299 ("drm/bridge: anx7625: Return -EPROBE_DEFER if the dsi host was not found") Reported-by:

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.)

Implement framebuffer I/O helpers, such as fb_read*() and fb_write*(), in the architecture's <asm/fb.h> header file or the generic one. 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. So the patch replaces this code with the __raw_*() functions and moves it to <asm-generic/fb.h> for all architectures. v8: * remove garbage after commit-message tags v6: * fix fb_readq()/fb_writeq() on 64-bit mips (kernel test robot) v5: * include <linux/io.h> in <asm-generic/fb>; fix s390 build v4: * ia64, loongarch, sparc64: add fb_mem*() to arch headers to keep current semantics (Arnd) v3: * implement all architectures with generic helpers * support reordering and native byte order (Geert, Arnd) Signed-off-by:
