serial: sh-sci: Add device tree support for r8a7{778,740,3a4} and sh73a0

2014-07-12T00:45:12+00:00

Simply document new compat strings.
There appears to be no need for a driver updates.

serial: uart: add hw flow control support configuration

2014-05-28T20:04:46+00:00

8250 uart driver currently supports only software assisted hw flow
control. The software assisted hw flow control maintains a hw_stopped
flag in the tty structure to stop and start transmission and use modem
status interrupt for the event to drive the handshake signals. This is
not needed if hw has flow control capabilities. This patch adds a
DT attribute for enabling hw flow control for a uart port. Also skip
stop and start if this flag is present in flag field of the port
structure.

tty/serial: at91: use mctrl_gpio helpers

2014-05-28T19:49:44+00:00

On sam9x5, dedicated CTS (and RTS) pins are unusable together with the
LCDC, the EMAC, or the MMC because they share the same line.

Moreover, the USART controller doesn't handle DTR/DSR/DCD/RI signals,
so we have to control them via GPIO.

This patch permits to use GPIOs to control the CTS/RTS/DTR/DSR/DCD/RI
signals.

tty/serial: atmel_serial: Fix device tree documentation

2014-05-28T19:44:32+00:00

RTS pin is an active low pin.
For now, this doesn't change anything as the ACTIVE_LOW flag is not
handled in atmel_serial, but it will be in 3.16.

serial: sh-sci: Add device tree support for r8a7779

2014-04-24T23:13:01+00:00

According to the platform data for the legacy-C initialisation of sh-sci
for the r8a7779 SoC and my own testing the SCIx_SH4_SCIF_REGTYPE bit of
scscr needs to be set.

serial: efm32: use $vendor,$device scheme for compatible string

2014-04-16T21:17:43+00:00

Wolfram Sang pointed out that "efm32,$device" is non-standard. So use the
common scheme and prefix device with "efm32-". The old compatible string
is left in place until arch/arm/boot/dts/efm32* is fixed.

Merge tag 'cleanup-3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

2014-04-05T20:51:19+00:00

Pull ARM SoC cleanups from Arnd Bergmann:
 "These cleanup patches are mainly move stuff around and should all be
  harmless.  They are mainly split out so that other branches can be
  based on top to avoid conflicts.

  Notable changes are:

   - We finally remove all mach/timex.h, after CLOCK_TICK_RATE is no
     longer used (Uwe Kleine-König)
   - The Qualcomm MSM platform is split out into legacy mach-msm and
     new-style mach-qcom, to allow easier maintainance of the new
     hardware support without regressions (Kumar Gala)
   - A rework of some of the Kconfig logic to simplify multiplatform
     support (Rob Herring)
   - Samsung Exynos gets closer to supporting multiplatform (Sachin
     Kamat and others)
   - mach-bcm3528 gets merged into mach-bcm (Stephen Warren)
   - at91 gains some common clock framework support (Alexandre Belloni,
     Jean-Jacques Hiblot and other French people)"
