When creating dumb buffers with 32bpp and 24bit colour depth this is default mode return by drm_mode_legacy_fb_format. So we need to support this for common dumb buffers to just work. Signed-off-by: Emil Renner Berthing <kernel@esmil.dk>

This adds a compatible for the high speed UARTs on the StarFive JH7100 RISC-V SoC. Just like the regular uarts we also need to keep the input clocks at their default rate and rely only on the divisor in the UART. Signed-off-by: Emil Renner Berthing <kernel@esmil.dk>

3 dayspinctrl: starfive: Reset pinmux settingsEmil Renner Berthing1-0/+66
Current u-boot doesn't seem to take into account that some GPIOs are configured as inputs/outputs of certain peripherals on power-up. This means it ends up configuring some GPIOs as inputs to more than one peripheral which the documentation explicitly says is illegal. Similarly it also ends up configuring more than one GPIO as output of the same peripheral. While not explicitly mentioned by the documentation this also seems like a bad idea. The easiest way to remedy this mess is to just disconnect all GPIOs from peripherals and have our pinmux configuration set everything up properly. This, however, means that we'd disconnect the serial console from its pins for a while, so add a device tree property to keep certain GPIOs from being reset.

3 daysusb: cdns3: starfive: Simplify mode initEmil Renner Berthing1-30/+21
The syscon regmap and offset to the USB mode register is only used at probe time, so there is no need to store it in the device data. Just get the regmap pointer in the cdns_mode_init() function where it is needed. Also this function never uses the platform device, so just pass the device pointer directly.

11 daysi2c: scx200_acb: depends on HAS_IOPORTJohannes Berg1-1/+1
It already depends on X86_32, but that's also set for ARCH=um. Recent changes made UML no longer have IO port access since it's not needed, but this driver uses it. Build it only for HAS_IOPORT. This is pretty much the same as depending on X86, but on the off-chance that HAS_IOPORT will ever be optional on x86 HAS_IOPORT is the real prerequisite.

12 daysdrm/xe/guc: Explicitly exit CT safe mode on unwindMichal Wajdeczko1-4/+6
During driver probe we might be briefly using CT safe mode, which is based on a delayed work, but usually we are able to stop this once we have IRQ fully operational. However, if we abort the probe quite early then during unwind we might try to destroy the workqueue while there is still a pending delayed work that attempts to restart itself which triggers a WARN. This was recently observed during unsuccessful VF initialization: [ ] xe 0000:00:02.1: probe with driver xe failed with error -62 [ ] ------------[ cut here ]------------ [ ] workqueue: cannot queue safe_mode_worker_func [xe] on wq xe-g2h-wq [ ] WARNING: CPU: 9 PID: 0 at kernel/workqueue.c:2257 __queue_work+0x287/0x710 [ ] RIP: 0010:__queue_work+0x287/0x710 [ ] Call Trace: [ ] delayed_work_timer_fn+0x19/0x30 [ ] call_timer_fn+0xa1/0x2a0 Exit the CT safe mode on unwind to avoid that warning.

12 daysnvme: fix atomic write size validationChristoph Hellwig2-24/+12
Don't mix the namespace and controller values, and validate the per-controller limit when probing the controller. This avoid spurious failures for controllers with namespaces that have different namespaces with different logical block sizes, or report the per-namespace values only for some namespaces. It also fixes a missing queue_limits_cancel_update in an error path by removing that error path.

12 daysnvme: reset delayed remove_work after reconnectKeith Busch2-1/+5
The remove_work will proceed with permanently disconnecting on the initial final path failure if the head shows no paths after the delay. If a new path connects while the remove_work is pending, and if that new path happens to disconnect before that remove_work executes, the delayed removal should reset based on the most recent path disconnect time, but queue_delayed_work() won't do anything if the work is already pending. Attempt to cancel the delayed work when a new path connects, and use mod_delayed_work() in case the remove_work remains pending anyway.

12 daysnet: enetc: Correct endianness handling in _enetc_rd_reg64Simon Horman1-1/+1
enetc_hw.h provides two versions of _enetc_rd_reg64. One which simply calls ioread64() when available. And another that composes the 64-bit result from ioread32() calls. In the second case the code appears to assume that each ioread32() call returns a little-endian value. However both the shift and logical or used to compose the return value would not work correctly on big endian systems if this were the case. Moreover, this is inconsistent with the first case where the return value of ioread64() is assumed to be in host byte order. It appears that the correct approach is for both versions to treat the return value of ioread*() functions as being in host byte order. And this patch corrects the ioread32()-based version to do so. This is a bug but would only manifest on big endian systems that make use of the ioread32-based implementation of _enetc_rd_reg64. While all in-tree users of this driver are little endian and make use of the ioread64-based implementation of _enetc_rd_reg64. Thus, no in-tree user of this driver is affected by this bug. Flagged by Sparse. Compile tested only.
