usb: phy: phy-rcar-usb: delete unnecessary 'out of memory' messages

2014-11-03T16:01:04Z

The memory subsystem has already had similar message for it. Signed-off-by: Peter Chen Signed-off-by: Felipe Balbi

usb: phy: use dev_get_platdata()

2013-07-30T08:18:53Z

Use the wrapper function for retrieving the platform data instead of accessing dev->platform_data directly. Signed-off-by: Jingoo Han Signed-off-by: Felipe Balbi

usb: phy: don't check resource with devm_ioremap_resource

2013-07-29T10:58:14Z

devm_ioremap_resource does sanity checks on the given resource. No need to duplicate this in the driver. Signed-off-by: Wolfram Sang Signed-off-by: Felipe Balbi

phy-rcar-usb: add R8A7778 support

2013-06-11T07:11:16Z

The driver currently only supports R8A7779 SoC. Compared to it, R8A7778 USB-PHY has extra register range containing two high-speed signal quality characteristic control registers which should be set up during USB-PHY startup depending on whether a ferrite bead is in use or not. So, we now handle an optional second memory range in the driver's probe method, add the 'ferrite_bead' field to the driver's platform data, and add an extra (optional) step to the USB-PHY startup routine which sets up the extended registers. Also mark in the driver's Kconfig section that R8A7778 is now supported and generally clarify that section, uppercasing the word "phy" and also changing the module name that got lost in the big driver rename, while at it... The patch has been tested on the Marzen and BOCK-W boards. Signed-off-by: Sergei Shtylyov Acked-by: Felipe Balbi Signed-off-by: Simon Horman

phy-rcar-usb: handle platform data

2013-06-11T07:10:49Z

Set the USBPCTRL0 register from the passed platform data in rcar_usb_phy_init(); don't reset it to 0 in rcar_usb_phy_shutdown() anymore as that does not make sense. Also, don't allow the driver's probe to succeed when the platform data are not supplied with a device. The patch has been tested on the Marzen and BOCK-W boards.

phy-rcar-usb: correct base address

2013-06-11T07:10:47Z

The memory region that is used by the driver overlaps EHCI and OHCI register regions for absolutely no reason now -- fix it by adding offset of 0x800 to the base address, changing the register #define's accordingly. This has extra positive effect that we now can use devm_ioremap_resource()... Note that the driver and the SoC code have to be in one patch to keep the code bisectable... The patch has been tested on the Marzen board. Signed-off-by: Sergei Shtylyov Acked-by: Kuninori Morimoto Acked-by: Felipe Balbi Signed-off-by: Simon Horman

phy-rcar-usb: remove EHCI internal buffer setup

2013-06-11T07:10:46Z

Now that the EHCI internal buffer setup is done by the platform code, we can remove such code from this driver as it never really belonged here. We also no longer need the 2nd memory region now (2nd EHCI controller is simply missing in e.g. R8A7778 SoC). The patch has been tested on the Marzen and BOCK-W boards.

usb: phy: rename all phy drivers to phy-$name-usb.c

2013-03-18T09:18:08Z

this will make sure that we have sensible names for all phy drivers. Current situation was already quite bad with too generic names being used. Signed-off-by: Felipe Balbi
