* arm: mvebu: Enable USB EHCI support on Armada XPStefan Roese2015-08-17-1/+8
| | | | | | | | | | | | | | | | | 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 Goede2015-08-08-2/+0
| | | | | | | | | | | | | | | | | | | | | 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>

* | Tegra: clocks: Add 38.4MHz OSC support for T210 useTom Warren2015-08-05-5/+13
|/ | | | | | | | | | | | | | | 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.

Note the #ifdef turns usb_find_emul_child() into a nop, rather then not building it and adding another #ifdef to the caller, this is done this way because adding a #ifdef to the caller is somewhat hairy.

The result of this commit is best seen in the output of "dm tree" after plugging out an usb hub with 2 devices plugges in and plugging in a keyb. instead, before this commit the output would be: usb [ + ] `-- sunxi-musb usb_hub [ ] |-- usb_hub usb_mass_st [ ] | |-- usb_mass_storage usb_dev_gen [ ] | `-- generic_bus_0_dev_3 usb_dev_gen [ + ] `-- generic_bus_0_dev_1 Notice the non active usb_hub child and its 2 non active children. The first child being non-active as in this example also causes usb_get_dev_index to return NULL when probing the first child, which results in the usb kbd code not binding to the keyboard. With this commit in place the output after swapping and "usb reset" is: usb [ + ] `-- sunxi-musb usb_dev_gen [ + ] `-- generic_bus_0_dev_1 As expected, and usb_get_dev_index works properly and the keyboard works.
