This patchset add basic support for i.MX6Quad Plus SOC.
change for v2:
-- address commnet from Fabio Estevam, split the dts
into three patch:
dts for imx6qp soc; dts for imx6qp-sabresd
and dts for imx6qp-sabreauto
-- fix a typo in commit, the chip name should be i.MX6Quad Plus
Bai Ping (5):
ARM: dts: imx: Add basic dts support for imx6qp SOC
ARM: dts: imx: Add basic dts support for imx6qp-sabresd
ARM: dts: imx: Add basic dts support for imx6qp-sabreauto
clk: imx: Add clock support for imx6qp
ARM: imx: Add msl code support for imx6qp

The i.MX6Quad Plus processor is an high performance SOC of i.MX6 family.
It has enhanced graphics performance and increased overall memory bandwidth
compared to i.MX6Q. Most of the design are same as i.MX6Quad/Dual, so code
for i.MX6Quad can be resued by this chip. The revision number is identied as
i.MX6Q Rev2.0, but actually it is a new chip, as we did many change to the
overall architecture.
This patch adds basic dtsi file support for the new i.MX6Quad Plus processor.

most of the clock tree structures on i.MX6QP are same as
on i.MX6Q. there still some difference between these two
SOCs. Compared to the i.MX6Q, the differences of clocks on
i.MX6QP is mainly on:
1. UART clk root
2. IPG_PER clk,
3. ENFC
4. ECSPI
5. CAN_SEL
6. CSCMR1 register fixup issue
7. LDB clock
8. GPU2D clock
9 MMDC_CH1_AXI gate ...

The i.MX6QP is a different SOC, but internally we treate
it as i.MX6Q Rev_2.0 to maximum the code reusability. The chip
silicon number we read from the ANADIG_DIGPROG is 0x630100. This
patch add code to identify it as i.MX6QP Rev_1.0 when print out the
silicon version.

For new dts files, we suggest to use GPL/X11 dual license to consider
non-Linux users. You can grep "dual-licensed" in arch/arm/boot/dts to

This file should be updated in the patch that updates clock driver.
Only after these new clocks get supported by clock driver, you can use
them in device tree.

Please keep the list sort alphabetically. That said,
imx6qp-sabresd.dtb should be added after imx6q-* ones.

So this change applies to imx6q and imx6dl sabresd as well?

Ah, that's why you do not include "imx6qdl.dtsi" in imx6qp.dtsi. I have
a question with this approach. How people should write his imx6qp board
dts file, if his board never has an imx6q version?

Since commit 5fcdf6a7ed95 (pinctrl: imx: Allow parsing DT without
function nodes), this additional container node can just be saved.

Please at least add some comment here to help us remember that this is
