Subject: [PATCH 1/5 v11] arm: omap: usb: ehci and ohci hwmod structures for omap4
Date: Thu, 22 Sep 2011 17:07:55 +0530	[thread overview]
Message-ID: <1316691479-1849-2-git-send-email-keshava_mgowda@ti.com> (raw)
In-Reply-To: <1316691479-1849-1-git-send-email-keshava_mgowda@ti.com>

From: Benoit Cousson <b-cousson@ti.com>

Following 4 hwmod structures are added
1. usb_host_hs hwmod of usbhs with uhh base address and functional clock,
2. usb_ehci_hs hwmod with irq and base address,
3. usb_ohci_hs hwmod with irq and base address,
   - The ehci and ohci hwmods does not require functional clock
     because usb_host_hs has functional clock which is sufficient
     to access ehci and ohci address space.
   - The usb_ehci_hs and usb_ohci_hs should be two separate hwmods
     which should not be combined. This is needed because ehci and
     ohci will have separate dedicated ports & in omap4 there is a
     clock per port.We should be able to configure the IO-Wakeup
     capability of pins specific to EHCI & OHCI separately and depending
     on the I/O wakeup event  the  only port clocks corresponding
     to the wakeup source will be enabled internally by the usb host driver.

4. usb_tll_hs hwmod of usbhs with the TLL base address and irq.

- The initial version had only two hwmods,usb_host_hs and usb_tll_hs.
These two hwmods are reorganized as above four hwmods, because there
will be dedicated ports for ehci and ohci; and each port will have I/O
mux, which will be initialized per hwmod in future.

- migrated these hwmod structures to Kevin's pm branch:
 git://git.kernel.org/pub/scm/linux/kernel/git/khilman/linux-omap-pm.git .
