Patches based on for-next
Patch 1,2 is to fix the lockdep warning reported by Leonard
Patch 3 is to fix pll mux bit
Patch 4 is align with other i.MX8M using gate
Patch 5 is to simplify i.MX8MP clk root using composite
Patch 3~5 is actually https://patchwork.kernel.org/patch/11402761/
with a minimal change to patch 5 here.
Patch 6 is to use composite core clk for A53 clk root
Patch 7,8,9 is actually to fix CORE/BUS clk slice issue.
This issue is triggerred after we update U-Boot to include
the A53 clk fixes to sources from PLL, not from A53 root clk,
because of the signoff timing is 1GHz. U-Boot set the A53 root
mux to 2, sys pll2 500MHz. Kernel will set the A53 root mux to
4, sys pll1 800MHz, then gate off sys pll2 500MHz. Then kernel
will gate off A53 root because clk_ignore_unsed, A53 directly sources
PLL, so it is ok to gate off A53 root. However when gate off A53
root clk, system hang, because the original mux sys pll2 500MHz
gated off with CLK_OPS_PARENT_ENABLE flag.
It is lucky that we not met issue for other core/bus clk slice
except A53 ROOT core slice. But it is always triggerred after
U-Boot and Linux both switch to use ARM PLL for A53 core, but
have different mux settings for A53 root clk slice.
So the three patches is to address this issue.
Not expect this merge in 5.6 release. Since this patchset is
worked out based on for-next and for-next will have conflicts
if the patchset based on master. And to make things easier,
we let all core/bus use composite api.
Patch 10 is make memrepair as critical.

From: Peng Fan <[email protected]>
Assign IMX8M*_CLK_A53_SRC's parent to system pll1 and
assign IMX8M*_CLK_A53_CORE's parent to arm pll out as what
is done in drivers/clk/imx/clk-imx8m*.c, then we could remove
the settings in driver which triggers lockdep warning.

From: Peng Fan <[email protected]>
Same to i.MX8MN/i.MX8MM, pll BYPASS bit should be kept inside pll
driver for glitchless freq setting following spec. If exposing the
bit, that means pll driver and clk driver has two paths to touch
this bit, which is wrong.
So use EXT_BYPASS bit here.

2.16.4
From: Peng Fan <[email protected]>
Inspried from
commit e8688fe8df7d ("clk: imx8mn: Define gates for pll1/2 fixed dividers")
On imx8mp there are 9 fixed-factor dividers for SYS_PLL1 and SYS_PLL2
each with their own gate. Only one of these gates (the one "dividing" by
one) is currently defined and it's incorrectly set as the parent of all
the fixed-factor dividers.
Add the other 8 gates to the clock tree between sys_pll1/2_bypass and
the fixed dividers.

From: Peng Fan <[email protected]>
Migrate A53 clk root to use composite core clk type. It
will simplify code and make it easy to use composite
specific mux operation.

2.16.4
From: Peng Fan <[email protected]>
The CORE/BUS root slice has following design, simplied graph:
The difference is core not have pre_div block.
A composite core/bus clk has 8 inputs for mux to select, saying clk[0-7].
SEL_A GA
+--+ +-+
| +->+ +------+
CLK[0-7]--->+ | +-+ |
| | | +----v---+ +----+
| +--+ |pre_diva+----> | +---------+
| +--------+ |mux +--+post_div |
| +--+ |pre_divb+--->+ | +---------+
| | | +----^---+ +----+
+--->+ | +-+ |
| +->+ +------+
+--+ +-+
SEL_B GB
There will be system hang, when doing the following steps:
1. switch mux from clk0 to clk1
2. gate off clk0
3. switch from clk1 to clk2, or gate off clk1
Step 3 triggers system hang.
If we skip step2, keep clk0 on, step 3 will not trigger system hang.
However we have CLK_OPS_PARENT_ENABLE flag, which will unprepare disable
the clk0 which will not be used.
To address this issue, we could use following simplied software flow:
After the first target register set
wait the target register set finished
set the target register set again
wait the target register set finished
The upper flow will make sure SEL_A and SEL_B both set the new mux,
but with only one path gate on.
And there will be no system hang anymore with step3.

Introduce imx8m_clk_hw_composite_bus api for bus clk root slice usage.
Because the mux switch sequence issue, we could not reuse Peripheral
Clock Slice code, need use composite specific mux operation.

If memrepair root clock in CCM is disabled, the memory repair logic
in HDMIMIX can’t work. So let's mark it as critical clock.

we could avoid possible issue when setting mux of the clk.

From: Peng Fan <[email protected]>

set parent here. And clk_hw_set_parent will trigger lockdep warning,
because this api not have prepare_lock.
