[Nishanth Menon]

BeagleBoard-X15 is the next generation Open Source Hardware
BeagleBoard based on TI's AM5728 SoC featuring dual core 1.5GHZ A15
processor. The platform features 2GB DDR3L (w/dual 32bit busses),
eSATA, 3 USB3.0 ports, integrated HDMI (1920x108@60), separate LCD
port, video In port, 4GB eMMC, uSD, Analog audio in/out, dual 1G
Ethernet.

For more information, refer to:
BeagleBoard-X15 Wiki:
http://www.elinux.org/Beagleboard:BeagleBoard-X15

AM5728 is part of the Sitara product family whose additional details
will be available: http://www.ti.com/lsds/ti/arm/overview.page

Technical Reference Manual for AM5728 is public domain at:
http://www.ti.com/lit/spruhz6

Just add basic support for the moment, the following updates are needed:
  i)	Ethernet - depends on SoC dts fixes
  ii)	USB Client (USB2) - depends on GPIO extcon
  ii)	HDMI - additional driver fixes pending
  iii)	Audio - additional driver fixes pending

[PATCH] ARM: dts: Add am57xx-beagle-x15

[Nishanth Menon]

BeagleBoard-X15 is the next generation Open Source Hardware
BeagleBoard based on TI's AM5728 SoC featuring dual core 1.5GHZ A15
processor. The platform features 2GB DDR3L (w/dual 32bit busses),
eSATA, 3 USB3.0 ports, integrated HDMI (1920x108 at 60), separate LCD
port, video In port, 4GB eMMC, uSD, Analog audio in/out, dual 1G
Ethernet.

For more information, refer to:
BeagleBoard-X15 Wiki:
http://www.elinux.org/Beagleboard:BeagleBoard-X15

AM5728 is part of the Sitara product family whose additional details
will be available: http://www.ti.com/lsds/ti/arm/overview.page

Technical Reference Manual for AM5728 is public domain at:
http://www.ti.com/lit/spruhz6

Just add basic support for the moment, the following updates are needed:
  i)	Ethernet - depends on SoC dts fixes
  ii)	USB Client (USB2) - depends on GPIO extcon
  ii)	HDMI - additional driver fixes pending
  iii)	Audio - additional driver fixes pending

Tested with omap2plus_defconfig modified as: http://slexy.org/view/s2DRTzUwjj
boot log: http://slexy.org/raw/s25Grf1uoo
based on 3.18-rc1 tag.

Support for u-boot has been posted as well: (series ending
http://patchwork.ozlabs.org/patch/407552/ )

Side note: this patch generates a few unrelated checkpatch warning for
compatible which probably is part of appropriate driver documentation
fixes (functionality is already present).

Yes, it should either be the full and correct value or 0x0 (like a

the right value here.

Oh neat, you put a USB3 hub on the board?

I really should cleanup and submit my patch to make the system time not
run 576ppm too fast on the AM57xx.

This will sure be a nice board when you get it released.  I will have
to get one.

Honest mistake, my bad.. I thought I cleaned up the patch! Sigh!!! i
will repost with proper 2GB. it is better that way in case being used
with "other bootloaders" which are not exactly too good like u-boot.

Oh neat, you put a USB3 hub on the board?

I really should cleanup and submit my patch to make the system time not run
576ppm too fast on the AM57xx.

This will sure be a nice board when you get it released.  I will have to get
one.

Convert 12V to 5V and 3.3V. 5V supplies are too expensive at the required
wattage level.

yep - will do that similar to
https://patchwork.kernel.org/patch/5125431/ - same rationale unless
there is any specific voltage rail that you are explicitly interested
in that needs additional explanation. Is there additional rails of
interest?

Here is what I have in mind: (updated with comments from Felipe/Tom and
above) - would you like more details added - if you could point out
areas of interest, I can help improve information provided here.

Subject: [PATCH V2] ARM: dts: Add am57xx-beagle-x15

BeagleBoard-X15 is the next generation Open Source Hardware
BeagleBoard based on TI's AM5728 SoC featuring dual core 1.5GHZ A15
processor. The platform features 2GB DDR3L (w/dual 32bit busses),
eSATA, 3 USB3.0 ports, integrated HDMI (1920x108@60), separate LCD
port, video In port, 4GB eMMC, uSD, Analog audio in/out, dual 1G
Ethernet.

For more information, refer to:
BeagleBoard-X15 Wiki:
http://www.elinux.org/Beagleboard:BeagleBoard-X15

AM5728 is part of the Sitara product family whose additional details
will be available: http://www.ti.com/lsds/ti/arm/overview.page

Technical Reference Manual for AM5728 is public domain at:
http://www.ti.com/lit/spruhz6

Just add basic support for the moment, the following updates are needed:
  i)	Ethernet - depends on SoC dts fixes
  ii)	USB Client (USB2) - depends on GPIO extcon
  ii)	HDMI - additional driver fixes pending
  iii)	Audio - additional driver fixes pending

NOTE:
AM5728 Data Manual (SPRS915L - August 2014) section 4.1.1 states: "All
unused power supply balls must be supplied with the voltages specified
in the Section 5.2, Recommended Operating Conditions". This implies
that all unused voltage rails for AM5728 can never be switched off even
if the hardware blocks inside that voltage domain is unused. Switching
off these unused rails may result in stability issues on other domains
and increased leakage and power-on-hour impacts.

Changes in V2 since V1:
	- Fix the missing squash of proper DDR size.

V1: https://patchwork.kernel.org/patch/5244801/

Additional references:
	- Missing ethernet dtsi patch series: http://marc.info/?t=141388585300001&r=1&w=2
	- Missing USB Client extcon patch series: http://marc.info/?t=141520160800004&r=1&w=2

Tested with omap2plus_defconfig modified as: http://slexy.org/view/s2DRTzUwjj
boot log: http://slexy.org/raw/s25Grf1uoo
based on 3.18-rc1 tag.

Support for u-boot has been posted as well: (series ending
http://patchwork.ozlabs.org/patch/407552/ )

Side note: this patch generates a few unrelated checkpatch warning for
compatible which probably is part of appropriate driver documentation
fixes (functionality is already present).

Here is what I have in mind: (updated with comments from Felipe/Tom and
above) - would you like more details added - if you could point out
areas of interest, I can help improve information provided here.

Subject: [PATCH V2] ARM: dts: Add am57xx-beagle-x15

BeagleBoard-X15 is the next generation Open Source Hardware
BeagleBoard based on TI's AM5728 SoC featuring dual core 1.5GHZ A15
processor. The platform features 2GB DDR3L (w/dual 32bit busses),
eSATA, 3 USB3.0 ports, integrated HDMI (1920x108@60), separate LCD
port, video In port, 4GB eMMC, uSD, Analog audio in/out, dual 1G
Ethernet.

For more information, refer to:
BeagleBoard-X15 Wiki:
http://www.elinux.org/Beagleboard:BeagleBoard-X15

AM5728 is part of the Sitara product family whose additional details
will be available: http://www.ti.com/lsds/ti/arm/overview.page

Technical Reference Manual for AM5728 is public domain at:
http://www.ti.com/lit/spruhz6

Just add basic support for the moment, the following updates are needed:
  i)	Ethernet - depends on SoC dts fixes
  ii)	USB Client (USB2) - depends on GPIO extcon
  ii)	HDMI - additional driver fixes pending
  iii)	Audio - additional driver fixes pending

NOTE:
AM5728 Data Manual (SPRS915L - August 2014) section 4.1.1 states: "All
unused power supply balls must be supplied with the voltages specified
in the Section 5.2, Recommended Operating Conditions". This implies
that all unused voltage rails for AM5728 can never be switched off even
if the hardware blocks inside that voltage domain is unused. Switching
off these unused rails may result in stability issues on other domains
and increased leakage and power-on-hour impacts.

Changes in V2 since V1:
	- Fix the missing squash of proper DDR size.

V1: https://patchwork.kernel.org/patch/5244801/

Additional references:
	- Missing ethernet dtsi patch series: http://marc.info/?t=141388585300001&r=1&w=2
	- Missing USB Client extcon patch series: http://marc.info/?t=141520160800004&r=1&w=2

Tested with omap2plus_defconfig modified as: http://slexy.org/view/s2DRTzUwjj
boot log: http://slexy.org/raw/s25Grf1uoo
based on 3.18-rc1 tag.

Support for u-boot has been posted as well: (series ending
http://patchwork.ozlabs.org/patch/407552/ )

Side note: this patch generates a few unrelated checkpatch warning for
compatible which probably is part of appropriate driver documentation
fixes (functionality is already present).

Here is what I have in mind: (updated with comments from Felipe/Tom and
above) - would you like more details added - if you could point out
areas of interest, I can help improve information provided here.

Subject: [PATCH V2] ARM: dts: Add am57xx-beagle-x15

BeagleBoard-X15 is the next generation Open Source Hardware
BeagleBoard based on TI's AM5728 SoC featuring dual core 1.5GHZ A15
processor. The platform features 2GB DDR3L (w/dual 32bit busses),
eSATA, 3 USB3.0 ports, integrated HDMI (1920x108 at 60), separate LCD
port, video In port, 4GB eMMC, uSD, Analog audio in/out, dual 1G
Ethernet.

For more information, refer to:
BeagleBoard-X15 Wiki:
http://www.elinux.org/Beagleboard:BeagleBoard-X15

AM5728 is part of the Sitara product family whose additional details
will be available: http://www.ti.com/lsds/ti/arm/overview.page

Technical Reference Manual for AM5728 is public domain at:
http://www.ti.com/lit/spruhz6

Just add basic support for the moment, the following updates are needed:
  i)	Ethernet - depends on SoC dts fixes
  ii)	USB Client (USB2) - depends on GPIO extcon
  ii)	HDMI - additional driver fixes pending
  iii)	Audio - additional driver fixes pending

NOTE:
AM5728 Data Manual (SPRS915L - August 2014) section 4.1.1 states: "All
unused power supply balls must be supplied with the voltages specified
in the Section 5.2, Recommended Operating Conditions". This implies
that all unused voltage rails for AM5728 can never be switched off even
if the hardware blocks inside that voltage domain is unused. Switching
off these unused rails may result in stability issues on other domains
and increased leakage and power-on-hour impacts.

Changes in V2 since V1:
	- Fix the missing squash of proper DDR size.

V1: https://patchwork.kernel.org/patch/5244801/

Additional references:
	- Missing ethernet dtsi patch series: http://marc.info/?t=141388585300001&r=1&w=2
	- Missing USB Client extcon patch series: http://marc.info/?t=141520160800004&r=1&w=2

Tested with omap2plus_defconfig modified as: http://slexy.org/view/s2DRTzUwjj
boot log: http://slexy.org/raw/s25Grf1uoo
based on 3.18-rc1 tag.

Support for u-boot has been posted as well: (series ending
http://patchwork.ozlabs.org/patch/407552/ )

Side note: this patch generates a few unrelated checkpatch warning for
compatible which probably is part of appropriate driver documentation
fixes (functionality is already present).
