Subject: [PATCH v3 00/42] ep93xx device tree conversion
This series aims to convert ep93xx from platform to full device tree support.
The main goal is to receive ACK's to take it via Arnd's arm-soc branch.
I've moved to b4, tricking it to consider v0 as v1, so it consider's
this version to be v3, this exactly the third version.
Link to previous versions:
https://lore.kernel.org/all/20230424123522.18302-1-nikita.shubin@maquefel.me/
Major changes with clocks:
- split all ep93xx clk into two groups:
- those who are special to ep93xx (i.e. can't be implemented via standard clk's)
and use special swlocked registers
- those who can be implemented via devm_clk_hw_register_gate, etc...
- moved all clk's that are not used via device tree to SoC driver
- dropped init and globals
- devm_* everywhere
Other notable changes:
- added a global spinlock for SoC driver to protect swlocked register's.
- moved dts file into cirrus
- dropped "dt-bindings: gpio: Add Cirrus EP93xx" as it was taken by
Bartosz via gpio subsystem
on master v6.5-rc2-89-g3acbd4602b05:
make dtbs_check
```
make -j34 -C build-linux ARCH=arm CROSS_COMPILE=armv4t-softfloat-linux-gnueabi- dtbs_check -s

cirrus,cs4271 is defined in linux/Documentation/devicetree/bindings/sound/cs4271.txt
`make dt_binding_check` shows no issues.
[PATCH v1 01/43] gpio: ep93xx: split device in multiple
- core.c:
- fixed tab used instead of space
- unsigned i in ep93xx_init_devices
- gpio-ep93xx.c:
- single line for EP93XX_INT_DEBOUNCE_OFFSET
- drop assignment from definition
- s/devm_kcalloc/devm_kzalloc/
- value check for platform_get_irq
- used dev_err_probe
- s/if (irq <= 0)/if (irq < 0)/
[PATCH v1 02/43] dt-bindings: soc: Add Cirrus EP93xx

- filename now matches compatible
- dropped description
- dropped clock description

- headers sorted
- fixed comment
- use lo_hi_readq and UINT_MAX
[PATCH 12/43] clk: ep93xx: add DT support for Cirrus EP93xx
- move out all clocks that aren't used in device tree to SoC driver (pll1, pll2, usb)
- drop all static variables (regmap, clock data)
- DMA and USB clocks as standart gates to avoid additional checks (all other require swlocked_write)
- rearranged ep93xx_clk members to avoid holes
- numerous fixes from Andy
- don't get revision, use soc_device_match instead
- added own clk_get function to distinguish fixed and own clocks
[PATCH v1 14/43] power: reset: Add a driver for the ep93xx reset
- added private data with regmap, as we dropped global regmap in SoC dirver
- use dev_err_probe
- + bits.h header
[PATCH v1 17/43] dt-bindings: spi: Add Cirrus EP93xx
- fixed filename to cirrus,ep9301-spi.yaml
- dropped address and size cells
- dropped cs-gpio

- s/derived/Derived from/
- BIT and GENMASK
- s/sizeof(struct ts72xx_nand_data)/sizeof(*data)/ and one line
- fixed wierd mtd_device_parse_register error handling
- added child node parsing to conform device tree bindings (i.e. partitions contained in 'nand@0' child node)
[PATCH v1 26/43] pata: cirrus: add DT support for Cirrus EP93xx
- headers reordering
- s/-ENXIO/-ENOMEM/

[PATCH v1 34/43] gpio: ep93xx: add DT support for gpio-ep93xx
- s/Add match table./Add OF ID match table./
