Subject: [PATCH v3 0/9] ARM: mstar: cpupll
Date: Fri, 21 Jan 2022 20:35:35 +0100 [thread overview]
Message-ID: <20220121193544.23231-1-romain.perier@gmail.com> (raw)
This series adds a basic driver for the PLL that generates
the cpu clock on MStar/SigmaStar ARMv7 SoCs.
Unfortunately there isn't much documentation for this thing
so there are few magic values and guesses.
This needs to come after the MPLL DT changes.
Changes since v2:
- Re-ordered Kconfig by name
- Re-ordered includes alphabetically and removed useless ones
- Used timeout for cpu_relax
- Returned DIV_ROUND_DOWN_ULL() directly in
msc313_cpupll_frequencyforreg()
- Returned DIV_ROUND_DOWN_ULL() directly in
msc313_cpupll_regforfrequecy()
- Reduced the number of lines for msc313_cpupll_of_match
- Removed CLK_IS_CRITICAL
Changes since v1:
- Re-worked the series and ensure that 'make dt_binding_check' passes.
The required commit is merged now, so it is okay.
- Fixed coding style issues in the driver and makes check_patch.pl happy
- Added one more commit for extending the opp_table for infinity2m.
