[PATCH v3 1/2] media: v4l2-cci: Add support for little-endian encoded registers

by Alexander Stein

Some sensors, e.g. Sony IMX290, are using little-endian registers. Add support for those by encoding the endianess into Bit 20 of the register address.

[PATCH] coresight: etm4x: Fix width of CCITMIN field

by James Clark

CCITMIN is a 12 bit field and doesn't fit in a u8, so extend it to u16. This probably wasn't an issue previously because values higher than 255 never occurred. But since commit 0f55b43dedcd ("coresight: etm: Override TRCIDR3.CCITMIN on errata affected cpus"), a comparison with 256 was done to enable the errata, generating the following W=1 build error: coresight-etm4x-core.c:1188:24: error: result of comparison of constant 256 with expression of type 'u8' (aka 'unsigned char') is always false [-Werror,-Wtautological-constant-out-of-range-compare] if (drvdata->ccitmin == 256) Cc: stable(a)vger.kernel.org Fixes: 54ff892b76c6 ("coresight: etm4x: splitting struct etmv4_drvdata") Signed-off-by: James Clark <james.clark(a)arm.com> --- drivers/hwtracing/coresight/coresight-etm4x.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/hwtracing/coresight/coresight-etm4x.h b/drivers/hwtracing/coresight/coresight-etm4x.h index 20e2e4cb7614..da17b6c49b0f 100644 --- a/drivers/hwtracing/coresight/coresight-etm4x.h +++ b/drivers/hwtracing/coresight/coresight-etm4x.h @@ -1036,7 +1036,7 @@ struct etmv4_drvdata { u8 ctxid_size; u8 vmid_size; u8 ccsize; - u8 ccitmin; + u16 ccitmin; u8 s_ex_level; u8 ns_ex_level; u8 q_support; -- 2.34.1

[PATCH v3] serial: 8250: 8250_omap: Clear UART_HAS_RHR_IT_DIS bit

From: Ronald Wahl <ronald.wahl(a)raritan.com> This fixes commit 439c7183e5b9 ("serial: 8250: 8250_omap: Disable RX interrupt after DMA enable") which unfortunately set the UART_HAS_RHR_IT_DIS bit in the UART_OMAP_IER2 register and never cleared it.

[PATCH v4] serial: 8250: 8250_omap: Do not start RX DMA on THRI interrupt

by Ronald Wahl

From: Ronald Wahl <ronald.wahl(a)raritan.com> Starting RX DMA on THRI interrupt is too early because TX may not have finished yet. This change is inspired by commit 90b8596ac460 ("serial: 8250: Prevent starting up DMA Rx on THRI interrupt") and fixes DMA issues I had with an AM62 SoC that is using the 8250 OMAP variant.

Possibly broken Linux 5.10.198 backport spi: spi-zynqmp-gqspi: Fix runtime PM imbalance in zynqmp_qspi_probe

by Marek Vasut

Linux 5.10.198 commit 2cdec9c13f81 ("spi: spi-zynqmp-gqspi: Fix runtime PM imbalance in zynqmp_qspi_probe") looks very different compared to matching upstream commit: a21fbc42807b ("spi: spi-zynqmp-gqspi: Fix runtime PM imbalance in zynqmp_qspi_probe") The Linux 5.10.198 change breaks a platform for me and it really looks like an incorrect backport. Dinghao, can you have a look ? Thank you

[REGRESSION] Userland interface breaks due to hard HFSC_FSC requirement

Hi, (prefix, I was not aware of the regression reporting process and incorrectly reported this informally with the developers mentioned in the change) I upgraded from 6.1.38 to 6.1.55 this morning and it broke my traffic shaping script, leaving me with a non-functional uplink on a remote router.

[PATCH v6 8/8] eventfs: Use simple_recursive_removal() to clean up dentries

by Steven Rostedt

From: "Steven Rostedt (Google)" <rostedt(a)goodmis.org> Looking at how dentry is removed via the tracefs system, I found that eventfs does not do everything that it did under tracefs. The tracefs removal of a dentry calls simple_recursive_removal() that does a lot more than a simple d_invalidate(). As it should be a requirement that any eventfs_inode that has a dentry, so does its parent. When removing a eventfs_inode, if it has a dentry, a call to simple_recursive_removal() on that dentry should clean up all the dentries underneath it. Add WARN_ON_ONCE() to check for the parent having a dentry if any children do. Link: https://lore.kernel.org/all/20231101022553.GE1957730@ZenIV/ Cc: stable(a)vger.kernel.org Cc: Al Viro <viro(a)zeniv.linux.org.uk> Fixes: 5bdcd5f5331a2 ("eventfs: Implement removal of meta data from eventfs") Signed-off-by: Steven Rostedt (Google) <rostedt(a)goodmis.org> --- Changes since the last patch: https://lore.kernel.org/linux-trace-kernel/20231031144703.71eef3a0@gandalf.… - Was originally called: eventfs: Process deletion of dentry more thoroughly - Al Viro pointed out that I could use simple_recursive_removal() instead. I had originally thought that I could not, but looking deeper into it, and realizing that if a dentry exists on any eventfs_inode, then all the parent eventfs_inode of that would als have a dentry. Hence, calling simple_recursive_removal() on the top dentry would clean up all the children dentries as well.
