by Tom Rini 05 Jan '21

05 Jan '21

Hey all, A day late, but here we are. I've taken a few small fixes in, and we've had a few small PRs. But I think things are looking good for release next week. In terms of a changelog, git log --merges v2021.01-rc4..v2021.01-rc5 contains what I've pulled but as always, better PR messages and tags will provide better results here. Thanks all! -- Tom

[PATCH v2] nvme: Use only 32-bit accesses in nvme_writeq/nvme_readq
by Stefan Agner 05 Jan '21

05 Jan '21

There might be hardware configurations where 64-bit data accesses to NVMe registers are not supported properly. This patch removes the readq/writeq so always two 32-bit accesses are used to read/write 64-bit NVMe registers, similarly as it is done in Linux kernel. This patch fixes operation of NVMe devices on RPi4 Broadcom BCM2711 SoC based board, where the PCIe Root Complex, which is attached to the system through the SCB bridge. Even though the architecture is 64-bit the PCIe BAR is 32-bit and likely the 64-bit wide register accesses initiated by the CPU are not properly translated to a sequence of 32-bit PCIe accesses. nvme_readq(), for example, always returns same value in upper and lower 32-bits, e.g. 0x3c033fff3c033fff which lead to NVMe devices to fail probing. This fix is analogous to commit 8e2ab05000ab ("usb: xhci: Use only 32-bit accesses in xhci_writeq/xhci_readq").

[PATCH] Nokia RX-51: Decrease i2c speed to 100000
by Pali Rohár 05 Jan '21

05 Jan '21

It looks like that i2c bus lot of times timeout on some units. Prior migration to CONFIG_DM_I2C i2c speed was set to CONFIG_SYS_OMAP24_I2C_SPEED value which was 100000. Lower speed fixes timeout problems, so change speed back to its previous value.

Hi, This driver is connected via spi on one ZynqMP board. Only 8bit SPI connection is supported now. Spi zynq driver was used for testing this driver. We have tested load image via BMP command and also using it as console as is visible from log in the last patch. Thanks, Michal Changes in v3: - also fix video_bmp call. - use 32bit reg/value parameters - new patch in this series Changes in v2: - New patch is series - New patch is series - Add support for returning value - Update kernel-doc format to pass kernel-doc script - Update patch subject s/call/operation/ - Fix Kconfig entry and use VIDEO_SEPS525 instead of SEPS525 and fix location - Add kernel-doc structure for seps525_priv structure - Remove flags variable and use macros directly Michal Simek (5): video: Fix video sync kernel-doc format video: Let video_sync to return error value video: Introduce video_sync operation video: seps525: Add seps525 SPI driver video: Call video_sync in video_clear() Vikhyat Goyal (1): video: seps525: Add dt binding description MAINTAINERS | 2 + .../video/syncoam,seps525.txt | 24 ++ drivers/video/Kconfig | 7 + drivers/video/Makefile | 1 + drivers/video/seps525.c | 327 ++++++++++++++++++ drivers/video/vidconsole-uclass.c | 40 ++- drivers/video/video-uclass.c | 23 +- drivers/video/video_bmp.c | 5 +- include/video.h | 22 +- 9 files changed, 426 insertions(+), 25 deletions(-) create mode 100644 doc/device-tree-bindings/video/syncoam,seps525.txt create mode 100644 drivers/video/seps525.c -- 2.29.2
