Hey all, new member here! As the subject line suggests, our development hardware does not support UniPro so we were looking at a guest kernel solution with TCP/IP transport over gbridge. However, one of the SDIO bus devices is a wifi module that requires DMA. Is this possible over the current gb-netlink/gbridge to your knowledge? Cheers, -- *—* *Kyle Harding* Embedded Linux Engineer, balena.io

[PATCH] staging: greybus: move to use request_irq by IRQF_NO_AUTOEN flag

disable_irq() after request_irq() still has a time gap in which interrupts can come. request_irq() with IRQF_NO_AUTOEN flag will disable IRQ auto-enable because of requesting. this patch is made base on "add IRQF_NO_AUTOEN for request_irq" which is being merged: https://lore.kernel.org/patchwork/patch/1388765/ Signed-off-by: Tian Tao <tiantao6(a)hisilicon.com> --- drivers/staging/greybus/arche-platform.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/staging/greybus/arche-platform.c b/drivers/staging/greybus/arche-platform.c index e374dfc..be27ace 100644 --- a/drivers/staging/greybus/arche-platform.c +++ b/drivers/staging/greybus/arche-platform.c @@ -500,13 +500,13 @@ static int arche_platform_probe(struct platform_device *pdev) arche_platform_wd_irq, arche_platform_wd_irq_thread, IRQF_TRIGGER_FALLING | - IRQF_TRIGGER_RISING | IRQF_ONESHOT, + IRQF_TRIGGER_RISING | IRQF_ONESHOT | + IRQF_NO_AUTOEN, dev_name(dev), arche_pdata); if (ret) { dev_err(dev, "failed to request wake detect IRQ %d\n", ret); return ret; } - disable_irq(arche_pdata->wake_detect_irq); ret = device_create_file(dev, &dev_attr_state); if (ret) { -- 2.7.4

[PATCH 00/16] tty: TIOCSSERIAL fixes and clean ups

by Johan Hovold

TIOCSSERIAL is a horrid, underspecified, legacy interface which for most serial devices is only useful for setting the close_delay and closing_wait parameters. This series fixes up the various ways in which driver authors have gotten the implementation wrong over the years, like, for example, jiffies conversions, permissions checks and error handling. The de-facto standard for error handling is to ignore any unsupported features and immutable parameters (cf. UPF_FIXED_PORT and deprecated ASYNC flags). Permission checking should prevent an unprivileged user from changing anything but the ASYNC_USR flags (and custom divisor) by returning -EPERM. These patches are against tty-next, but the staging ones could otherwise go through either tree. I'll be sending the corresponding USB fixes separately.

[PATCH 00/10] spi: finalize 'delay_usecs' removal/transition

by Alexandru Ardelean

A while back I started the introduction of the 'spi_delay' data type: https://lore.kernel.org/linux-spi/20190926105147.7839-1-alexandru.ardelean@… Users of the 'delay_usecs' were removed from drivers. Now it's time to remove the 'delay_usecs' from the SPI subsystem and use only the 'delay' field. This changeset adapts all SPI drivers to do without 'delay_usecs'. Additionally, for greybus we need to adapt it to use the 'delay' in nano-seconds and convert it to micro-seconds. Alexandru Ardelean (10): spi: spi-axi-spi-engine: remove usage of delay_usecs spi: bcm63xx-spi: don't check 'delay_usecs' field spi: spi-bcm-qspi: replace 'delay_usecs' with 'delay.value' check spi: spi-sh: replace 'delay_usecs' with 'delay.value' in pr_debug spi: spi-tegra20-flash: don't check 'delay_usecs' field for spi transfer staging: greybus: spilib: use 'spi_delay_to_ns' for getting xfer delay spi: spi-falcon: remove check for 'delay_usecs' spi: fsl-espi: remove usage of 'delay_usecs' field spi: core: remove 'delay_usecs' field from spi_transfer spi: docs: update info about 'delay_usecs' Documentation/spi/spi-summary.rst | 7 +++++-- drivers/spi/spi-axi-spi-engine.c | 12 ++++-------- drivers/spi/spi-bcm-qspi.c | 2 +- drivers/spi/spi-bcm63xx.c | 2 +- drivers/spi/spi-falcon.c | 2 +- drivers/spi/spi-fsl-espi.c | 17 +++++------------ drivers/spi/spi-sh.c | 4 ++-- drivers/spi/spi-tegra20-sflash.c | 3 +-- drivers/spi/spi.c | 1 - drivers/staging/greybus/spilib.c | 5 ++++- include/linux/spi/spi.h | 12 ------------ 11 files changed, 24 insertions(+), 43 deletions(-) -- 2.29.2
