parisc/serial: Rename 8250_gsc.c to 8250_parisc.c

2022-10-21T06:10:46Z

The file name of this driver is misleading - it handles various serial ports on parisc machines, not just such on the GSC bus. Rename the file to make this clearer. Suggested-by: Mikulas Patocka Signed-off-by: Helge Deller

parisc: Make 8250_gsc driver dependend on CONFIG_PARISC

2022-10-21T06:10:45Z

Although the name of the driver 8250_gsc.c suggests that it handles only serial ports on the GSC bus, it does handle serial ports listed in the parisc machine inventory as well, e.g. the serial ports in a C8000 PCI-only workstation. Change the dependency to CONFIG_PARISC, so that the driver gets included in the kernel even if CONFIG_GSC isn't set. Reported-by: Mikulas Patocka Cc: Signed-off-by: Helge Deller

serial: 8250: SERIAL_8250_ASPEED_VUART should depend on ARCH_ASPEED

2022-07-14T14:27:55Z

The Aspeed Virtual UART is only present on Aspeed BMC platforms. Hence add a dependency on ARCH_ASPEED, to prevent asking the user about this driver when configuring a kernel without Aspeed BMC support.

serial: 8250: Correct Kconfig help text for blacklisted PCI devices

2022-02-25T09:33:50Z

Correct the Kconfig help text for SERIAL_8250_LPSS, SERIAL_8250_MID and SERIAL_8250_PERICOM configuration options for dedicated PCI UART drivers that have been blacklisted in the generic PCI 8250 UART driver and as from commit a13e19cf3dc10 ("serial: 8250_lpss: split LPSS driver to separate module"), commit d9eda9bab2372 ("serial: 8250_pci: Intel MID UART support to its own driver"), and commit fcfd3c09f4078 ("serial: 8250_pci: Split out Pericom driver") respectively are not handled by said driver anymore (rather than for extra features only, as the current text indicates), and therefore require the respective dedicated drivers to work at all.

Pericom along with Acces I/O support consumes a lot of LOCs in 8250_pci.c. For the sake of easier maintenance, split it to a separate driver. Signed-off-by: Andy Shevchenko Link: https://lore.kernel.org/r/20211122133512.8947-2-andriy.shevchenko@linux.intel.com Signed-off-by: Greg Kroah-Hartman

serial: 8250: allow disabling of Freescale 16550 compile test

2021-10-05T13:07:44Z

The SERIAL_8250_FSL option is used to enable a workaround for a break-detection erratum for Freescale 16550 UARTs in the 8250 driver and is currently also used to enable support for ACPI enumeration. It is enabled on PPC, ARM and ARM64 whenever 8250 console support is enabled (since the quirk is needed for sysrq handling). Commit b1442c55ce89 ("serial: 8250: extend compile-test coverage") enabled compile testing of the code in question but did not provide a means to disable the option when COMPILE_TEST is enabled. Add a conditional input prompt instead so that SERIAL_8250_FSL is no longer enabled by default when compile testing while continuing to always enable the quirk for platforms that may need it.

serial: 8250: extend compile-test coverage

Allow more drivers to be compile tested more easily, for example, when doing subsystem-wide changes. Verified on X86_64 as well as arm, powerpc and m68k with minimal configs in order to catch missing implicit build dependencies.
