Commit Message

Peter Griffin April 4, 2024, 12:25 p.m. UTC 
CMU_HSI2 is the clock management unit used for the hsi2 block.
HSI stands for High Speed Interface and as such it generates
clocks for PCIe, UFS and MMC card.

This patch adds support for the muxes, dividers, and gates in
cmu_hsi2.

CLK_GOUT_HSI2_HSI2_CMU_HSI2_PCLK is marked as CLK_IS_CRITICAL
as disabling it leads to an immediate system hang.

CLK_GOUT_HSI2_SYSREG_HSI2_PCLK is also marked CLK_IS_CRITICAL.
A hang is not observed with fine grained clock control, but
UFS IP does not function with syscon controlling this clock
just around hsi2_sysreg register accesses.

CLK_GOUT_HSI2_GPIO_HSI2_PCLK is marked CLK_IGNORE_UNUSED until
the exynos pinctrl clock patches land then it can be removed.

Some clocks in this unit have very long names. To help with this
the clock name mangling strategy was updated to include removing
the following sub-strings.
- G4X2_DWC_PCIE_CTL_
- G4X1_DWC_PCIE_CTL_
- PCIE_SUB_CTRL_
- INST_0_
- LN05LPE_
- TM_WRAPPER_
- SF_

Hi Pete,

Thanks for this!

I haven't reviewed this, but one immediate comment...

Can you please keep the #defines alphabetical (hsi before misc).

You need to add these defines as part of the patch that is updating the
binding (patch 1 this series).

Is it doable to use shorter register names while still keeping them
close to datasheet/manual? This one is a bit too much... actually most
of them are quite too much. :)

Keep these also alphabetically ordered by compatible.

Would it make sense to add this clock to the &ufs_0 node in the DTS
instead? Seems more natural than a clock that's constantly enabled?

Can you make these alphabetical, too, please, which would also match their usage

Here and below: all these extra empty lines are not needed.

The two strings fit on the same line.

I have a similar clock in USB, which also causes a hang if off, I wonder what we
could do better here.
