[PATCH v4 00/42] ep93xx device tree conversion

[PATCH v4 00/42] ep93xx device tree conversion

[Nikita Shubin via B4 Relay]

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.

Major changes:
- drop newline at the end from each YAML files
- rename dma and clk bindings headers to match first compatible
- shrink SoC exported functions number to only 2
- dropped some ep93xx_pata fixes from these series
- dropped m48t86 stuff from these series

Bit thanks to Andy Shevchenko for thorough review.

Some parts are were sent in advance, so these series depends on the
following:

Changes in v4:

- gpio: ep93xx: split device in multiple
  - s/generic_handle_irq/generic_handle_domain_irq/
  - s/int offset/irq_hw_number_t offset/ though now it looks a bit odd to me
  - drop i = 0
  - drop 'error'
  - use dev_err_probe withour printing devname once again

dt-bindings: clock: Add Cirrus EP93xx
  - renamed cirrus,ep93xx-clock.h -> cirrus,ep9301-clk.h

clk: ep93xx: add DT support for Cirrus EP93xx
  - drop unused includes
  - use .name only for xtali, pll1, pll2 parents
  - convert // to /*
  - pass clk_parent_data instead of char* clock name

dt-bindings: pinctrl: Add Cirrus EP93xx
  - s/additionalProperties/unevaluatedProperties/

dt-bindings: soc: Add Cirrus EP93xx
  - move syscon to soc directory
  - add vendor prefix
  - make reboot same style as pinctrl, clk
  - use absolute path for ref
  - expand example

soc: Add SoC driver for Cirrus ep93xx
  - s/0xf0000000/GENMASK(31, 28)/
  - s/ret/ep93xx_chip_revision(map)/
  - drop symbol exports
  - convert to platform driver

dt-bindings: rtc: Add Cirrus EP93xx
  - allOf: with $ref to rtc.yaml
  - s/additionalProperties/unevaluatedProperties/

dt-bindings: watchdog: Add Cirrus EP93x
  - drop description
  - reword

power: reset: Add a driver for the ep93xx reset
  - lets use 'GPL-2.0+' instead of '(GPL-2.0)'
  - s/of_device/of/
  - drop mdelay with warning
  - return 0 at the end

net: cirrus: add DT support for Cirrus EP93xx
  - fix leaking np

mtd: nand: add support for ts72xx
  - +bits.h
  - drop comment
  - ok to fwnode_get_next_child_node
  - use goto to put handle and nand and report error

ARM: dts: add Cirrus EP93XX SoC .dtsi
  - add simple-bus for ebi, as we don't require to setup anything
  - add arm,pl011 compatible to uart nodes
  - drop i2c-gpio, as it's isn't used anywhere

ARM: dts: ep93xx: add ts7250 board
  - generic node name for temperature-sensor
  - drop i2c
  - move nand, rtc, watchdog to ebi node
 
- Link to v3: https://lore.kernel.org/r/20230605-ep93xx-v3-0-3d63a5f1103e@maquefel.me

Re: [PATCH v4 26/42] mtd: nand: add support for ts72xx

I initially agreed to accept a first version of this controller driver
with a legacy API because people were apparently under time pressure to
get this in. I see it's been a couple of months, so this is not that
urgent after all. As the driver is only 166 lines long, I would
strongly prefer a very straight ->exec_op() conversion in order to get
rid of these ugly direct I/O accesses.

Thanks,
Miquèl

You are welcome!

Dunno if you have used --patience when formatted the patches, but I think
you should, if hadn't, for the next version. It will help a lot in reviewing
and understanding the changes.
