usb: ehci-atmel: Convert to platform remove callback returning void The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Eventually after all drivers are converted, .remove_new() is renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

This patch also fixes a bug introduced by 3440ef1 (ARM: at91/dt: fix USB high-speed clock to select UTMI), which was leaving the usb clock uninitialized and preventing the OHCI driver from setting the usb clock rate to 48MHz. This bug was caused by several things: 1/ usb clock drivers set the CLK_SET_RATE_GATE flag, which means the rate cannot be changed once the clock is prepared 2/ The EHCI driver was retrieving and preparing/enabling the uhpck clock which was in turn preparing its parent clock (the usb clock), thus preventing any rate change because of 1/ Fixes: 3440ef169100 ("ARM: at91/dt: fix USB high-speed clock to select UTMI") Signed-off-by: Boris Brezillon <boris.brezillon@free-electrons.com> Acked-by: Alan Stern <stern@rowland.harvard.edu> Acked-by: Nicolas Ferre <nicolas.ferre@atmel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

USB: set device dma_mask without reference to global data Many USB host drivers contain code such as: if (!pdev->dev.dma_mask) pdev->dev.dma_mask = &tegra_ehci_dma_mask; ... where tegra_ehci_dma_mask is a global. I suspect this code originated in commit 4a53f4e "USB: ehci-tegra: add probing through device tree" and was simply copied everywhere else. This works fine when the code is built-in, but can cause a crash when the code is in a module. The first module load sets up the dma_mask pointer, but if the module is removed and re-inserted, the value is now non-NULL, and hence is not updated to point at the new location, and hence points at a stale location within the previous module load address, which in turn causes a crash if the pointer is de-referenced. The simplest way of solving this seems to be to copy the code from ehci-platform.c, which uses the coherent_dma_mask as the target for the dma_mask pointer.

USB: EHCI: make ehci-atmel a separate driver Separate the Atmel host controller driver from ehci-hcd host code so that it can be built as a separate driver module. This work is part of enabling multi-platform kernels on ARM; however, note that other changes are still needed before Atmel can be booted with a multi-platform kernel. This is currently planned for Linux-3.11. With the infrastructure added by Alan Stern in patch 3e0232039 "USB: EHCI: prepare to make ehci-hcd a library module", we can avoid this problem by turning a bus glue into a separate module, as we do here for the Atmel bus glue. In V4 (arnd): - reordered #include statements. - removed call to ehci_shutdown and the corresponding export In V3: - Detailed commit message added here about why this patch is required. - Replaced hcd_name string "ehci-atmel" to "atmel-ehci". - Inserted blank line in the Makefile to separate the EHCI drivers from the following non-EHCI drivers. - Exported ehci_shutdown symbol as it is needed by the Atmel driver. - Eliminated ehci_atmel_setup routine because hcd registers can be directly set in the ehci_atmel_drv_probe function.

USB: EHCI: remove ehci_port_power() routine This patch (as1623) removes the ehci_port_power() routine and all the places that call it. There's no reason for ehci-hcd to change the port power settings; the hub driver takes care of all that stuff. There is one exception: When the controller is resumed from hibernation or following a loss of power, the ports that are supposed to be handed over to a companion controller must be powered on first. Otherwise the handover won't work. This process is not visible to the hub driver, so it has to be handled in ehci-hcd.

EHCI: centralize controller initialization This patch (as1564c) converts the EHCI platform drivers to use the central ehci_setup() routine for generic controller initialization rather than each having its own idiosyncratic approach. The major point of difficulty lies in ehci-pci's many vendor- and device-specific workarounds. Some of them have to be applied before calling ehci_setup() and some after, which necessitates a fair amount of code motion. The other platform drivers require much smaller changes. One point not addressed by the patch is whether ports should be powered on or off following initialization. The different drivers appear to handle this pretty much at random. In fact it shouldn't matter, because the hub driver turns on power to all ports when it binds to the root hub. Straightening that out will be left for another day.

usb: Add in missing EHCI helpers. Several of the EHCI glue drivers either predate or were merged in the same timeframe as API changes at the USB core level, resulting in some missing endpoint_reset and clear_tt_buffer_complete callbacks. This fixes up all of ehci-atmel, mxc, w90x900, and xilinx-of to tie in the new helpers, which brings them in line with everyone else.
