[PATCH v5 0/9] Add Omapl138-Hawkboard support

[vm.rod25]

From: Victor Rodriguez <victor.rodriguez@sasken.com>

This patch adds
EMAC, EDMA, ASoC, SOUND, MMC/SD and USB OHCI
support for the Hawkboard-L138 system
It is under the machine name "omapl138_hawkboard".
This system is based on the da850 davinci CPU architecture.

Victor Rodriguez (9):
  davinci: EMAC support for Omapl138-Hawkboard
  davinci: EDMA support for Omapl138-Hawkboard
  davinci: ASoC support for Omapl138-Hawkboard
  davinci: McASP configuration for Omapl138-Hawkboard
  davinci: Audio support for Omapl138-Hawkboard
  davinci: MMC/SD and USB-OHCI configuration for Omapl138-Hawkboard
  davinci: MMC/SD support for Omapl138-Hawkboar
  davinci: USB clocks for Omapl138-Hawkboard

-1 need not be a new line. In any case, please include a ',' after it.

Hey Sergei these patches have been tested by Rene Gonzales and ack by
Liam and Mark Brown , I am going to send the patches V6 because of
this change. I have been rechecking the code and seems that there is
no problem on it, do you have any other comment before i send the
series of patches v6 ?

Thanks a lot for your comments

Really appreciated

[PATCH v5 9/9] davinci: USB1.1 support for Omapl138-Hawkboard

[vm.rod25]

From: Victor Rodriguez <victor.rodriguez@sasken.com>

This patch adds USB1.1 support for the Hawkboard-L138 system

Signed-off-by: Victor Rodriguez <victor.rodriguez@sasken.com>

Notes:

This patch works with da8xx_omapl_defconfig
In order to test it select in menuconfig like insmodule

 Device Drivers  --->
    SCSI device support  --->
       SCSI device support
       legacy /proc/scsi/ support
       SCSI disk support
       SCSI low-level drivers

       USB support  --->
               Support for Host-side US
               OHCI HCD support (NEW)
               USB Mass Storage support (NEW)
               USB Gadget Support  --->
               USB Gadget Drivers (Ethernet Gadget\
                (with CDC Ethernet support))  --->
               NOP USB Transceiver Driver

And you will be able to mount and USB pen drive

In order to connect a keyboard or a mouse on a USB-hub
select in menuconfig like insmodule

HID Devices  --->
       Generic HID support
       USB Human Interface Device (full HID) support
