tty: riscv: Using RISCV_SBI_V01 instead of RISCV_SBI

2020-04-21T23:15:04+00:00

As shown in SBI v0.2, the legacy console SBI functions (sbi_console_getchar()
and sbi_console_putchar()) are expected to be deprecated; they have no replacement.

Let's HVC_RISCV_SBI and SERIAL_EARLYCON_RISCV_SBI depends on RISCV_SBI_V01.

2020-04-03T20:22:40+00:00

Pull char/misc driver updates from Greg KH:
 "Here is the big set of char/misc/other driver patches for 5.7-rc1.

  Lots of things in here, and it's later than expected due to some
  reverts to resolve some reported issues. All is now clean with no
  reported problems in linux-next.

  Included in here is:
   - interconnect updates
   - mei driver updates
   - uio updates
   - nvmem driver updates
   - soundwire updates
   - binderfs updates
   - coresight updates
   - habanalabs updates
   - mhi new bus type and core
   - extcon driver updates
   - some Kconfig cleanups
   - other small misc driver cleanups and updates

  As mentioned, all have been in linux-next for a while, and with the
  last two reverts, all is calm and good"

tty: serial: make SERIAL_SPRD depend on COMMON_CLK

2020-03-26T14:41:03+00:00

kbuild-test reported an error:

  config: mips-randconfig-a001-20200321 ...
  >> drivers/tty/serial/sprd_serial.c:1175: undefined reference
  to `clk_set_parent'

Because some mips Kconfig selects HAVE_CLK but not COMMON_CLK and no
clk_set_parent implemented, so the error was exposed. So adding
dependence on COMMON_CLK can fix this issue.

Revert "tty: serial: samsung_tty: build it for any platform"

2020-03-17T14:22:23+00:00

This reverts commit 175b558d0efb8b4f33aa7bd2c1b5389b912d3019.

When the user configures a kernel without support for Samsung SoCs, it
makes no sense to ask the user about enabling "Samsung SoC serial
support", as Samsung serial ports can only be found on Samsung SoCs.

tty: source all tty Kconfig files in one place

2020-03-12T16:17:30+00:00

'source' (include) all of the tty/*/Kconfig files from
drivers/tty/Kconfig instead of from drivers/char/Kconfig.
This consolidates them both in source code and in menu
presentation to the user.

Move hvc/Kconfig and serial/Kconfig 'source' lines into the
if TTY/endif block and remove the if TTY/endif blocks from
those 2 files.

Remove the dependency with ARCH_SPRD from sprd serial/console Kconfig-s,
since we want them can be built-in when ARCH_SPRD is set as 'm'.

serial: ar933x_uart: add RS485 support

2020-03-06T12:26:26+00:00

Emulate half-duplex operation and use mctrl_gpio to add support for
RS485 tranceiver with transmit/receive switch hooked to RTS GPIO line.
This is needed to make use of the RS485 port found on Teltonika RUT955.

tty: serial: samsung_tty: remove SERIAL_SAMSUNG_DEBUG

2020-02-20T12:46:28+00:00

Since a05025d0ce72 ("tty: serial: samsung_tty: use standard debugging
macros") this configuration option is not used at all, so remove it from
the Kconfig file.

tty: serial: samsung_tty: build it for any platform

There is no need to tie this driver to only a specific SoC, or compile
test, so remove that dependancy from the Kconfig rules.
