ARM: dts: AM33XX: Add device tree data

Add device tree data of pinctrl, d_can, lis331dlh and tmp275 drivers for AM33XX family of devices. These patches were submitted earlier and reviewed. Re-sending to apply cleanly on linux-omap/devel-dt tree. These patches were tested on am33xx-evm and am335x-bone.

Add AM335x cpu0 clock entry to the corresponding clock data file. This is useful in getting the correct mpu clock pointer to change the cpu frequency in cpufreq driver.

Hi

Looks like this one is unrelated to the DTS changes, so I'll queue it separately here for 3.7.

Thanks Paul

Thanks

Add lis331dlh device tree data to am335x-evm.dts. In AM335x EVM lis331dlh accelerometer is connected to I2C2 bus. So this patch change the status of I2C2 node to "okay" to use I2C2 bus. Also added all the required platform data to am335x-evm.

Add temperature sensor DT data to am335x-evm.dts. In AM335x EVM tmp275 temperature sensor is connected to I2C2 bus. So this patch adds child node inside i2c2 node with i2c slave address. This patch is tested on AM335x EVM.

Hi Anil,

Thanks for the rebase / repost. I'll pulled the full series if Paul is OK with
ARM: OMAP2+: AM33XX: Add clock entries to omap_clk data

Paul,
Is that OK?

Benoit

Hi Beno?t

Looks to me like the clock change is unrelated to the DTS changes? Best thing would be if you could just take the DTS changes and I'll take the clkdev alias change.

Otherwise if that doesn't work I can ack it, but there might be some conflicts with other clkdev data changes.

- Paul

Good point, it can be separated.

No problem, that's fine for me.

Regards,
Benoit

Thanks Benoit,

What about Matt's series to fix the I2C number? Should it be applied on top of that one?

Regards,
Benoit

I had the series to fix the GPIO numbering [1]. It's dependent on this series which carries the led dts patch. Pantelis has a patch for i2c dts numbering in his i2c series [2]. A hunk in that patch has support for his i2c pinctrl series mixed in (not sure where that one is due to the change to early init) so it doesn't apply cleanly alone on top of for_3.7/dts_part2. If you're willing to pick up that i2c renumbering by itself I can drop you a patch just for that part.
