Subject: [PATCH v2 0/7] ARM: mstar: Basic MPLL support
Date: Thu, 11 Feb 2021 14:21:59 +0900 [thread overview]
Message-ID: <20210211052206.2955988-1-daniel@0x0f.com> (raw)
This series adds support for the MPLL block that is present in
MStar/SigmaStar ARMv7 SoCs.
This block is intended to be set and forgotten about before
Linux is running so all it actually does it read the registers
and calculate what the output frequencies should be.
We only care about this block because there are upstream dividers,
gates, muxes etc that need something between the input crystal
and themselves to calculate their own rates.
Changes since v1:
- The clock output name related parts of the binding
description are gone. Clock names are generated inside the driver.
I dropped Rob's reviewed-by because of these changes.
- A devm helper has been added for clk_hw_register_fixed_factor()
to allow drivers to register multiple fixed factor clks
without having to handle all of the clean up.
- Numerous clean ups to the mpll driver itself based on Stephen's
feedback.
