[PATCH v2 0/4] clk: meson: Add video clocks path

[PATCH v2 0/4] clk: meson: Add video clocks path

[Neil Armstrong]

This patchset is an attempt to handle the Amlogic Meson GX Video clock
in the Common Clock Framework in order to move the video pipeline and
HDMI controller clock management out of the Meson DRM Driver.

In order :
- Add support the VID_PLL fully programmable divider used right after the
  HDMI PLL clock source.
- Fix the GXL HDMI PLL DCO
- Add the video clock bindings covering all the video graphics pipeline
  and the HDMI controller.
- Add the clocks entries used in the video clock path

The vid_pll programmable divider is introduced in its R/O form right now,
but will be extended to be R/W in a next iteration.

All dividers are flagged with CLK_GET_RATE_NOCACHE, and all gates are flagged
with CLK_IGNORE_UNUSED since they are currently directly handled by the
Meson DRM Driver.

Once the DRM Driver is fully migrated to using the Common Clock Framework
to handle the video clock tree, the CLK_GET_RATE_NOCACHE and CLK_IGNORE_UNUSED
will be dropped.

Changes since v1 at [1]:
 - Fixed comments from Martin
 - Fixed GXL HDMI PLL DCO
 - Added the missing HDMI controller clock
 - Moved bindings to a separate patch
 - Updated the commit logs

[PATCH v2 2/4] clk: meson-gxbb: Fix HDMI PLL for GXL SoCs

[Neil Armstrong]

In an attempt to better describe the HDMI PLL, a single DCO clock was
left for GXBB and GXL, but the GXL DCO does not have a pre-multiplier.

This patch adds back a GXL specific HDMI PLL DCO with xtal as parent.

according to the public S905X datasheet (from Khadas)
HHI_HDMI_PLL_CNTL2[31:30] describe the OD_FB
the 32-bit SoCs probably have an OD_FB as well and it seems that the
formula for the PLL with OD_FB is:
  in * m / n >> od << od_fb
(however, I must admit that I'm not sure where od_fb fits in best:
before the PLL DCO - like OD is after the PLL DCO, or part of the PLL
DCO)

so this is more of a question than a suggestion/feedback:
do you know whether the datasheet is correct and there's really a
programmable multiplier (called OD_FB)?
do you have more details on that topic?

Martin

[PATCH v2 4/4] clk: meson-gxbb: Add video clocks

[Neil Armstrong]

Add the clocks entries used in the video clock path, the clock path
is doubled to permit having different synchronized clocks for different
parts of the video pipeline.

All dividers are flagged with CLK_GET_RATE_NOCACHE, and all gates are flagged
with CLK_IGNORE_UNUSED since they are currently directly handled by the
Meson DRM Driver.
Once the DRM Driver is fully migrated to using the Common Clock Framework
to handle the video clock tree, the CLK_GET_RATE_NOCACHE and CLK_IGNORE_UNUSED
will be dropped.

[PATCH v2 4/4] clk: meson-gxbb: Add video clocks

[Neil Armstrong]

Add the clocks entries used in the video clock path, the clock path
is doubled to permit having different synchronized clocks for different
parts of the video pipeline.

All dividers are flagged with CLK_GET_RATE_NOCACHE, and all gates are flagged
with CLK_IGNORE_UNUSED since they are currently directly handled by the
Meson DRM Driver.
Once the DRM Driver is fully migrated to using the Common Clock Framework
to handle the video clock tree, the CLK_GET_RATE_NOCACHE and CLK_IGNORE_UNUSED
will be dropped.

[PATCH v2 4/4] clk: meson-gxbb: Add video clocks

[Neil Armstrong]

Add the clocks entries used in the video clock path, the clock path
is doubled to permit having different synchronized clocks for different
parts of the video pipeline.

All dividers are flagged with CLK_GET_RATE_NOCACHE, and all gates are flagged
with CLK_IGNORE_UNUSED since they are currently directly handled by the
Meson DRM Driver.
Once the DRM Driver is fully migrated to using the Common Clock Framework
to handle the video clock tree, the CLK_GET_RATE_NOCACHE and CLK_IGNORE_UNUSED
will be dropped.

does it select from 7 or 8 parents? you are listing only 7
the same applies for the usages below

for the fclk_divX clocks we use the clk_fixed_factor as parent of the gate
you're doing it the other way around here (as well as for the vclk1
clocks above and the other vclk2 clocks below)
I'm not sure which way is correct though

I'm aware that this has been applied already
I only found a few nit-picks - so this is looking good!

you could get rid of the comment if you inline
gxbb_vid_pll_parent_names and set num_parents to 2 manually

does it select from 7 or 8 parents? you are listing only 7
the same applies for the usages below

for the fclk_divX clocks we use the clk_fixed_factor as parent of the gate
you're doing it the other way around here (as well as for the vclk1
clocks above and the other vclk2 clocks below)
I'm not sure which way is correct though

I'm aware that this has been applied already
I only found a few nit-picks - so this is looking good!

you could get rid of the comment if you inline
gxbb_vid_pll_parent_names and set num_parents to 2 manually

does it select from 7 or 8 parents? you are listing only 7
the same applies for the usages below

for the fclk_divX clocks we use the clk_fixed_factor as parent of the gate
you're doing it the other way around here (as well as for the vclk1
clocks above and the other vclk2 clocks below)
I'm not sure which way is correct though
