USB: serial: cp210x: fix GPIO in autosuspend

2019-03-10T06:09:01+00:00

commit 7b0b644b9aa2de5032db0f468fddca091d0b7b90 upstream. Current GPIO code in cp210x fails to take USB autosuspend into account, making it practically impossible to use GPIOs with autosuspend enabled without user configuration. Fix this like for ftdi_sio in a previous patch. Tested on a CP2102N.

commit 0326ccb5feac6eac35ba6254260e2774277cd976 upstream. During initialization, the host and super-speed power domains will contain an ERR_PTR() encoded error code rather than being NULL.

usb: typec: tcpm: Correct the PPS out_volt calculation

2019-01-31T08:14:00+00:00

When Sink negotiates PPS, the voltage range of selected PPS APDO might not cover the previous voltage (out_volt). If the previous out_volt is lower than the new min_volt, the output voltage in RDO might be set to an invalid value. For instance, supposed that the previous voltage is 5V, and the new voltage range in the APDO is 7V-12V. Then the output voltage in the RDO should not be set to 5V which is lower than the possible min_volt 7V. Fix this by choosing the maximal value between the previous voltage and the new min_volt first. And ensure that this value will not exceed the new max_volt. The new out_volt will fall within the new voltage range while being the closest value compared to the previous out_volt.

Merge tag 'fixes-for-v5.0-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-linus

Felipe writes: usb: fixes for v5.0-rc4 Dwc3 got a fix for cases when gadget driver queue an OUT request of length 0; this is a case that has been overlooked for quite some time now. Exynos' dwc3 glue layer got a fix on the error path for those cases where clk_prepare_enable() fails. TI's AM335x PHY driver got a fix for a race condition during probe. This race happened because driver was powering off the PHY only after adding the PHY handle to the framework. The result is that we could fall into a situation where user of the PHY (MUSB) could call phy_init() before phy driver's probe() called phy_poweroff() which would result in a powered off PHY after phy_init() was called. The old net2272 driver got a fix for an erroneous use of bitwise negation. * tag 'fixes-for-v5.0-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb: usb: phy: am335x: fix race condition in _probe usb: dwc3: exynos: Fix error handling of clk_prepare_enable usb: phy: fix link errors usb: gadget: udc: net2272: Fix bitwise and boolean operations usb: dwc3: gadget: Handle 0 xfer length for OUT EP

usb: gadget: musb: fix short isoc packets with inventra dma

2019-01-30T14:48:10+00:00

Handling short packets (length < max packet size) in the Inventra DMA engine in the MUSB driver causes the MUSB DMA controller to hang. An example of a problem that is caused by this problem is when streaming video out of a UVC gadget, only the first video frame is transferred. For short packets (mode-0 or mode-1 DMA), MUSB_TXCSR_TXPKTRDY must be set manually by the driver. This was previously done in musb_g_tx (musb_gadget.c), but incorrectly (all csr flags were cleared, and only MUSB_TXCSR_MODE and MUSB_TXCSR_TXPKTRDY were set). Fixing that problem allows some requests to be transferred correctly, but multiple requests were often put together in one USB packet, and caused problems if the packet size was not a multiple of 4. Instead, set MUSB_TXCSR_TXPKTRDY in dma_controller_irq (musbhsdma.c), just like host mode transfers.

power off the phy should be done before populate the phy. Otherwise, am335x_init() could be called by the phy owner to power on the phy first, then am335x_phy_probe() turns off the phy again without the caller knowing it.
