2012-04-18USB: ehci-s5p: add clock gating to suspend/resumeJingoo Han1-0/+4
This patch adds clock gating to suspend and resume functions. Signed-off-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2012-03-08USB: ehci-s5p: add DMA burst supportJingoo Han1-0/+15
DMA burst support is added to improve performance in EHCI data transfer. The USB EHCI controller on Exynos SoCs can use INCR16, INCR8, and INCR4 mode. These modes of INSNREG00 register should be set in order to enable DMA burst transfer. This feature is also related to AHB spec.

2011-12-08usb: Remove ehci_reset call from ehci_runGeoff Levand1-0/+2
Remove the ehci_reset() call done in the ehci_run() routine of the USB EHCI host controller driver and add an ehci_reset() call to the probe processing of all EHCI platform drivers that do not already call ehci_reset(). The call to ehci_reset() from ehci_run() was problematic for several platform drivers, and unnecessary for others. This change moves the decision to call ehci_reset() at driver startup to the platform driver code. Signed-off-by: Geoff Levand <geoff@infradead.org> Acked-by: Alan Stern <stern@rowland.harvard.edu>

2011-08-22USB: EHCI: remove usages of hcd->stateAlan Stern1-1/+1
This patch (as1483) improves the ehci-hcd driver family by getting rid of the reliance on the hcd->state variable. It has no clear owner and it isn't protected by the usual HCD locks. In its place, the patch adds a new, private ehci->rh_state field to record the state of the root hub. Along the way, the patch removes a couple of lines containing redundant assignments to the state variable. Also, the QUIESCING state simply gets changed to the RUNNING state, because the driver doesn't make any distinction between them.

2011-08-22usb: s5p-ehci: fix a NULL pointer deferenceYulgon Kim1-0/+1
This patch fixes a NULL pointer deference. A NULL pointer dereference happens since s5p_ehci->hcd field is not initialized yet in probe function.

This patch adds power management support such as suspend and resume functions. Signed-off-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2011-05-10USB: ehci-s5p : use __devinit and __devexit macros for probe and removeJingoo Han1-3/+3
The __devinit and __devexit macros were added to probe and remove functions. The macros move the probe and remove functions to the devinit and devexit sections Signed-off-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2011-05-03USB: EHCI: Support controllers with big endian capability regsJan Andersson1-1/+2
The two first HC capability registers (CAPLENGTH and HCIVERSION) are defined as one 8-bit and one 16-bit register. Most HC implementations have selected to treat these registers as part of a 32-bit register, giving the same layout for both big and small endian systems. This patch adds a new quirk, big_endian_capbase, to support controllers with big endian register interfaces that treat HCIVERSION and CAPLENGTH as individual registers.

2011-04-13USB: Add initial S5P EHCI driverJoonyoung Shim1-0/+201
This patch adds host USB high speed driver for samsung S5P series. This is initial driver and we need additional implementation to support some functions like power management.
