| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | port at91_udc driver from linux: original commit Message: commit c94e289f195e0e13cf34d27f9338d28221a85751 Author: Arnd Bergmann <arnd@arndb.de> Date: Sat Apr 11 00:14:21 2015 +0200 usb: gadget: remove incorrect __init/__exit annotations A recent change introduced a link error for the composite printer gadget driver: `printer_unbind' referenced in section `.ref.data' of drivers/built-in.o: defined in discarded section `.exit.text' of drivers/built-in.o Evidently the unbind function should not be marked __exit here, because it is called through a callback pointer that is not necessarily discarded, __composite_unbind() is indeed called from the error path of composite_bind(), which can never work for a built-in driver. Looking at the surrounding code, I found the same problem in all other composite gadget drivers in both the bind and unbind functions, as well as the udc platform driver 'remove' functions. Those will break if anyone uses the 'unbind' sysfs attribute to detach a device from a built-in driver. This patch removes the incorrect annotations from all the gadget drivers.

* usb: ehci: remember init modeStephen Warren2015-09-07-1/+7
| | | | | | | | | | | | | | When an EHCI device is registered in device mode, the HW isn't actually initialized at all, and hence isn't left in a running state. Consequently, when the device is deregistered, ehci_shutdown() will fail, since the HW bits it expects to see set in response to its shutdown requests will not be sent, and the message "EHCI failed to shut down host controller." will be printed. Fix ehci-hcd.c to remember whether the device was registered in host or device mode, and only call ehci_shutdown() for host mode registrations. Signed-off-by: Stephen Warren <swarren@nvidia.com>

| | | | | | | | | | | | | | | | | This patch enables the USB EHCI support for the Marvell Armada XP (AXP) SoCs. In compatism to the Armada 38x (A38x), the AXP needs to configure the USB PLL and the USB PHY's specifically in U-Boot. The A38x has done this already in the bin_hdr (SPL U-Boot). Without this, accessing the controller registers in U-Boot or Linux will hang the CPU. Additionally, the AXP uses a different USB EHCI base address. This patch also takes care of this by runtime SoC detection in the Marvell EHCI driver.

* sunxi: usb-phy: Never power off the usb portsHans de Goede2015-08-08-14/+16
| | | | | | | | | | | | | | | | | | | | | USB devices are not really designed to get the power bounced off and on at them. Esp. USB powered harddisks do not like this. Currently we power off the USB ports both on a "usb reset" and when booting the kernel, causing the usb-power to bounce off and then back on again. This patch removes the powering off calls, fixing the undesirable power bouncing. Note this requires some special handling for the OTG port: 1) We must skip the external vbus check if we've already enabled our own vbus to avoid false positives 2) If on an usb reset we no longer detect that the id-pin is grounded, turn off vbus as that means an external vbus may be present now Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>

|/ | | | | | | | | | | | | | | Added 38.4MHz/48MHz entries to pll_x_table for CPU PLL. Needs to be measured - should be close to 700MHz (1.4G/2). Note that some freqs aren't in the PLLU table in T210 TRM (13, 26MHz), so I used the 12MHz table entry for them. They shouldn't be selected since they're not viable T210 OSC freqs. Since there are now 2 new OSC defines, all tables (pll_x_table, PLLU) had to increase by two entries, but since 38.4/48MHz are not viable osc freqs on T20/30/114, etc, they're just set to 0.
