ARM: at91: debug: use DEBUG_UART_PHYS

2015-09-21T14:31:15+00:00

Instead of having to add a new configuration option each time support for
new SoC is added, use CONFIG_DEBUG_UART_PHYS. For now,
CONFIG_DEBUG_UART_VIRT is automatically computed.

Merge tag 'imx-soc-4.3' of git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux into next/soc

2015-08-18T20:10:05+00:00

The i.MX SoC changes for 4.3:
 - Add i.MX6 Ultralite SoC support, which is the newest addition to
   i.MX6 family.  It integrates a single Cortex-A7 core and a power
   management module that reduces the complexity of external power
   supply and simplifies power sequencing.
 - Change SNVS RTC driver to use syscon interface for register access,
   and add SNVS power key driver support.
 - Add a second clock for mxc rtc driver, and support device tree probe
   for the driver.
 - Add FEC MAC reference clock and phy fixup initialization for i.MX6UL
   platform.

ARM: zynq: Fix earlyprintk in big endian mode

2015-07-22T07:37:58+00:00

earlyprintk messages are not appearing on the terminal
emulator during a big endian kernel boot. In BE mode
sending full words to UART will result in unprintable
characters as they are byte swapped versions of printable
ones. So send only bytes.

2015-06-10T23:58:05+00:00

The i.MX SoC updates for 4.2:
 - Add new SoC i.MX7D support, which integrates two Cortex-A7 and one
   Cortex-M4 cores.
 - Support suspend from IRAM on i.MX53, so that DDR pins can be set to
   high impedance for more power saving during suspend.
 - Move i.MX clock drivers from arch/arm/mach-imx to drivers/clk/imx.
 - Move i.MX GPT timer driver from arch/arm/mach-imx into
   drivers/clocksource.
 - A couple of clock driver update for VF610 and i.MX6Q.
 - A few random code correction and improvement.

ARM: unify MMU/!MMU addruart calls

2015-05-20T21:09:51+00:00

Remove the needless differences between MMU/!MMU addruart calls.
This allows to use the same addruart macro on SoC level. Useful
for SoC consisting of multiple CPUs with and without MMU such as
Freescale Vybrid.
