net: handle HAS_IOPORT dependencies

2024-04-08T10:56:56+00:00

In a future patch HAS_IOPORT=n will disable inb()/outb() and friends at
compile time. We thus need to add HAS_IOPORT as dependency for
those drivers requiring them. For the DEFXX driver the use of I/O
ports is optional and we only need to fence specific code paths. It also
turns out that with HAS_IOPORT handled explicitly HAMRADIO does not need
the !S390 dependency and successfully builds the bpqether driver.

hamradio: baycom: remove useless link in Kconfig

2023-09-22T07:17:05+00:00

The Kconfig help text for baycom drivers suggests that more information
on the hardware can be found at . The website now
includes no information on their ham radio products other than a mention
that they were once produced by the company, saying:
"The amateur radio equipment is now no longer part and business of BayCom GmbH"

As there is no information relavent to the baycom driver on the site,
remove the link.

hamradio: drop ISA_DMA_API dependency

2023-04-19T12:11:41+00:00

It looks like the dependency got added accidentally in commit a553260618d8
("[PATCH] ISA DMA Kconfig fixes - part 3"). Unlike the previously removed
dmascc driver, the scc driver never used DMA.

net: hamradio: remove support for DMA SCC devices

2022-04-27T11:22:56+00:00

Another incarnation of Z8530, looks like? Again, no real changes
in the git history, and it needs VIRT_TO_BUS. Unlikely to have
users, let's spend less time refactoring dead code...

dmascc: add CONFIG_VIRT_TO_BUS dependency

2021-09-28T12:12:07+00:00

Many architectures don't define virt_to_bus() any more, as drivers
should be using the dma-mapping interfaces where possible:

In file included from drivers/net/hamradio/dmascc.c:27:
drivers/net/hamradio/dmascc.c: In function 'tx_on':
drivers/net/hamradio/dmascc.c:976:30: error: implicit declaration of function 'virt_to_bus'; did you mean 'virt_to_fix'? [-Werror=implicit-function-declaration]
  976 |                              virt_to_bus(priv->tx_buf[priv->tx_tail]) + n);
      |                              ^~~~~~~~~~~
arch/arm/include/asm/dma.h:109:52: note: in definition of macro 'set_dma_addr'
  109 |         __set_dma_addr(chan, (void *)__bus_to_virt(addr))
      |                                                    ^~~~

Add the Kconfig dependency to prevent this from being built on
architectures without virt_to_bus().

treewide: replace '---help---' in Kconfig files with 'help'

2020-06-13T16:57:21+00:00

Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over
'---help---'"), the number of '---help---' has been gradually
decreasing, but there are still more than 2400 instances.

This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.

There are a variety of indentation styles found.

  a) 4 spaces + '---help---'
  b) 7 spaces + '---help---'
  c) 8 spaces + '---help---'
  d) 1 space + 1 tab + '---help---'
  e) 1 tab + '---help---'    (correct indentation)
  f) 1 tab + 1 space + '---help---'
  g) 1 tab + 2 spaces + '---help---'

In order to convert all of them to 1 tab + 'help', I ran the
following commend:

  $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'
