Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet""

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.

This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing
changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

clk: imx6: Add definition for IMX6QDL_CLK_ENET_REF clock

After commit 673f6597321d ("net: fec_mxc: support i.MX8M with CLK_CCF") all
NXP boards, which are not IMX8 and in the same time are supporting CCF need
to provide PTP clock.

SHA1: 5752b50477da)to provide clocks support as it is used on the Linux
kernel with Common Clock Framework [CCF] setup.

The directory structure has been preserved. The ported code only supports
reading information from PLL, MUX, Divider, etc and enabling/disabling
the clocks USDHCx/ECSPIx depending on used bus. Moreover, it is agnostic
to the alias numbering as the information about the clock is read from the

clk: Add support for I2C clocks on NXP's imx6q SoC which use CCF

This change adds support for I2C clock modeled in CCF. This code intention
is to only enable those clocks in the I2C driver with default settings.
For that reason the "busy" versions of clocks reuse the generic approach
and would need to be updated when one wants to adjust the I2C clock
frequency in U-Boot.

clk: Port Linux common clock framework [CCF] for imx6q to U-boot (tag: v5.1.12)

This patch brings the files from Linux kernel (linux-stable/linux-5.1.y
SHA1: 5752b50477da)to provide clocks support as it is used on the Linux
kernel with Common Clock Framework [CCF] setup.

The directory structure has been preserved. The ported code only supports
reading information from PLL, MUX, Divider, etc and enabling/disabling
the clocks USDHCx/ECSPIx depending on used bus. Moreover, it is agnostic
to the alias numbering as the information about the clock is read from the
device tree.

One needs to pay attention to the comments indicating necessary for U-Boot's
driver model changes.

If needed, the code can be extended to support the "set" part of the clock
management.

clk: imx6: Add definition for IMX6QDL_CLK_ENET_REF clock

After commit 673f6597321d ("net: fec_mxc: support i.MX8M with CLK_CCF") all
NXP boards, which are not IMX8 and in the same time are supporting CCF need
to provide PTP clock.

On the i.MX6Q this clock is provided with IMX6QDL_CLK_ENET_REF in the Linux

Code in this change models the simplest case when enet reference clock is

The directory structure has been preserved. The ported code only supports

clk: Add support for I2C clocks on NXP's imx6q SoC which use CCF

This change adds support for I2C clock modeled in CCF. This code intention
is to only enable those clocks in the I2C driver with default settings.
For that reason the "busy" versions of clocks reuse the generic approach
and would need to be updated when one wants to adjust the I2C clock

clk: Port Linux common clock framework [CCF] for imx6q to U-boot (tag: v5.1.12)

This patch brings the files from Linux kernel (linux-stable/linux-5.1.y
SHA1: 5752b50477da)to provide clocks support as it is used on the Linux
kernel with Common Clock Framework [CCF] setup.

The directory structure has been preserved. The ported code only supports
reading information from PLL, MUX, Divider, etc and enabling/disabling
the clocks USDHCx/ECSPIx depending on used bus. Moreover, it is agnostic
to the alias numbering as the information about the clock is read from the
device tree.

One needs to pay attention to the comments indicating necessary for U-Boot's
driver model changes.

If needed, the code can be extended to support the "set" part of the clock
management.

clk: imx6: Add definition for IMX6QDL_CLK_ENET_REF clock

After commit 673f6597321d ("net: fec_mxc: support i.MX8M with CLK_CCF") all
NXP boards, which are not IMX8 and in the same time are supporting CCF need
to provide PTP clock.

On the i.MX6Q this clock is provided with IMX6QDL_CLK_ENET_REF in the Linux

This patch brings the files from Linux kernel (linux-stable/linux-5.1.y
SHA1: 5752b50477da)to provide clocks support as it is used on the Linux
kernel with Common Clock Framework [CCF] setup.

The directory structure has been preserved. The ported code only supports
reading information from PLL, MUX, Divider, etc and enabling/disabling
the clocks USDHCx/ECSPIx depending on used bus. Moreover, it is agnostic
to the alias numbering as the information about the clock is read from the

clk: Add support for I2C clocks on NXP's imx6q SoC which use CCF

This change adds support for I2C clock modeled in CCF. This code intention
is to only enable those clocks in the I2C driver with default settings.
For that reason the "busy" versions of clocks reuse the generic approach
and would need to be updated when one wants to adjust the I2C clock
frequency in U-Boot.

clk: Port Linux common clock framework [CCF] for imx6q to U-boot (tag: v5.1.12)

This patch brings the files from Linux kernel (linux-stable/linux-5.1.y
SHA1: 5752b50477da)to provide clocks support as it is used on the Linux
kernel with Common Clock Framework [CCF] setup.

The directory structure has been preserved. The ported code only supports
reading information from PLL, MUX, Divider, etc and enabling/disabling
the clocks USDHCx/ECSPIx depending on used bus. Moreover, it is agnostic
to the alias numbering as the information about the clock is read from the
device tree.

One needs to pay attention to the comments indicating necessary for U-Boot's
driver model changes.

If needed, the code can be extended to support the "set" part of the clock
management.

clk: imx6: Add definition for IMX6QDL_CLK_ENET_REF clock

After commit 673f6597321d ("net: fec_mxc: support i.MX8M with CLK_CCF") all
NXP boards, which are not IMX8 and in the same time are supporting CCF need
to provide PTP clock.

On the i.MX6Q this clock is provided with IMX6QDL_CLK_ENET_REF in the Linux
kernel's CCF.

Code in this change models the simplest case when enet reference clock is
generated from 'osc' clock.

need to provide IMX6QDL_CLK_ENET.

This change defines the missing clock in i.MX6Q's CCF.
