This is the default out-of-reset voltage, but if only the i.MX6 SoC got reset, the PMIC might still be stuck at the lower voltage for the slow operating point.

	a256667 Browse files » net: designware: look for a child device node for MDIO bus ... The Designware driver registers a local MDIO bus for each MAC device, but without setting a device node pointer for the MDIO bus device. In this case, mdiobus_register() will use the MDIO bus's parent device node (if any) as the MDIO device node. If the MAC device node has a child node compatible with "snps,dwmac-mdio", let us use that as the MDIO bus device node. Otherwise, leave the MDIO bus device node pointer set to NULL and carry on as before. The upshot is that PHY device nodes can now be placed in an intermediate node for the MDIO bus instead of having to place them directly in the Designware MAC device node. (Tested on a Terasic DE0-Nano-SoC with a suitably modified device tree.)

2018-10-29	b7705a1 Browse files » fs: devfs: implement d_revalidate hook ... The files in devfs can change withouut the fs layer noticing, so we have to revalidate dentries before using them. A failure could be triggered with: ls /dev/nand0.root.ubi; ubiattach /dev/nand0.root; ls /dev/nand0.root.ubi The first 'ls' would create a dentry for nand0.root.ubi with no inode associated since it does not yet exist. 'ubiattach' then creates that file, but the second 'ls' does not show it since the dentry is not revalidated and thus no inode is added to that dentry. This patch fixes this and also the opposite case when a file is removed (for example with ubidetach).

	eb18806 Browse files » usb: gadget: set maxpacket_limit ... Gadget update to 3.15 imported Linux patch e117e742d310 ("usb: gadget: add "maxpacket_limit" field to struct usb_ep"): This patch adds "maxpacket_limit" to struct usb_ep. This field contains maximum value of maxpacket supported by driver, and is set in driver probe. This value should be used by autoconfig() function, because value of field "maxpacket" is set to value from endpoint descriptor when endpoint becomes enabled. So when autoconfig() function will be called again for this endpoint, "maxpacket" value will contain wMaxPacketSize from descriptior instead of maximum packet size for this endpoint. For this reason this patch adds new field "maxpacket_limit" which contains value of maximum packet size (which defines maximum endpoint capabilities). This value is used in ep_matches() function used by autoconfig(). Value of "maxpacket_limit" should be set in UDC driver probe function, using usb_ep_set_maxpacket_limit() function, defined in gadget.h. This function set choosen value to both "maxpacket_limit" and "maxpacket" fields. However said update didn't bring in all driver changes. Do it now.

	28b38c1 Browse files » usb: gadget: fsl_udc: pass controller instance to unregister ... ci_udc_unregister() used to unregister "the controller". Since we may register multiple chipidea devices we called ci_udc_unregister() for each of them. This led to messages like: ERROR: imx-usb 53f80000.usb: gadget not registered. Fix this by returning the registered controller. This allows us to call ci_udc_unregister() only when we actually registered one before.

	610a2b2 Browse files » usb: host: ehci: do not use dev->priv ... An ehci can be registered with ehci_register which is passed a struct device_d *. In that case the priv pointer may already be used by the caller, so we must not use it in the ehci code. At least for the Atmel ehci driver this fixes a bug, here dev->priv is set two times to different values. Since we need dev->priv in the ehci code to get the controller in ehci_detect() we can no longer implement that without the help of the caller, hence we eport ehci_detect() and epect it to be called by the code which registers a ehci host.
