Subject: [PATCH v4 0/5] usb: phy: samsung: Introducing usb phy driver for samsung SoCs
Date: Fri, 10 Aug 2012 12:40:26 +0530	[thread overview]
Message-ID: <1344582631-13658-1-git-send-email-p.paneri@samsung.com> (raw)

Changes from v3:
Replaced susbsys_initcall()/module_exit() by module_platform_driver().
Accordingly in the hsotg driver returned -EPROBE_DEFER until phy driver
is registered
Removed unnecessary devm_usb_put_phy() call from the hsotg driver remove.

Changes from v2:
Changed the driver filenames to samsung-usbphy
Changed 's3c' to 'samsung' for platform device as well as platform data
Moved platform data structure to a separate file
Rectified coding style related errors

Changes from v1:
Rebased patches to latest usb-next branch
Changed the name 'sec_usbphy' to 'samsung_usbphy'

This patch set introduces a phy driver for samsung SoCs. It uses the existing
transceiver infrastructure to provide phy control functions. Use of this driver
can be extended for usb host phy as well. Over the period of time all the phy
related code for most of the samsung SoCs can be integrated here.
Removing the existing phy code from mach-s3c64xx. Same can be done for other SoCs
when they start supporting this phy driver. 
This driver is tested with smdk6410 and Exynos4210(with DT).
