[PATCH 0/3] ARM: dts: imx6ull: fix some incompatibilities between i.MX6UL and i.MX6ULL

[Lothar Waßmann]

This patchset addresses some differences between i.MX6UL and i.MX6ULL
which have slipped through the cracks so far.

- UART8 is not on SPBA but on AIPS-3
- i.MX6ULL has an ESAI interface in the address range of the UART8 on i.MX6UL
- i.MX6ULL does not have a CAAM unit nor SIM interfaces

[PATCH 1/3] ARM: dts: imx6ull: fix the i.MX6ULL UART8 configuration

[Lothar Waßmann]

UART8 on i.MX6ULL is not located on the SPBA bus like on i.MX6UL but
on the (otherwise unused) AIPS-3 bus.
Create the appropriate AIPS-3 bus configuration and move the uart8
definition where it belongs.

[PATCH 2/3] ARM: dts: imx6ull: add support for the esai interface

[Lothar Waßmann]

The address space taken by the UART8 on the i.MX6UL is used for the
ESAI interface on i.MX6ULL.

Since the ESAI unit on i.MX6ULL has two more bits in the TFCR register
(TFIN, TAENB) it deserves to get its own compatible string, though the
bits are currently not used by the driver.

[PATCH 3/3] ARM: dts: imx6ull: address some more incompatibilites between i.MX6UL and i.MX6ULL

[Lothar Waßmann]

The i.MX6ULL doesn't have the CAAM engine nor any SIM interface.
These are currently not implemented for i.MX6UL but it cannot hurt to
delete the corresponding nodes from the i.MX6ULL DTB anyway.

Should them be separate patches?

Otherwise this patch is ok to me.

As mentioned, this really should be 3 patches. At least split out the
