ARM: Convert to using %pOF instead of full_name

2017-08-16T20:25:30+00:00

Now that we have a custom printf format specifier, convert users of
full_name to use %pOF instead. This is preparation to remove storing
of the full path string for each node.

ARM: align .data section

2017-08-14T15:22:55+00:00

Robert Jarzmik reports that his PXA25x system fails to boot with 4.12,
failing at __flush_whole_cache in arch/arm/mm/proc-xscale.S:215:

   0xc0019e20 <+0>:     ldr     r1, [pc, #788]
   0xc0019e24 <+4>:     ldr     r0, [r1]	<== here

with r1 containing 0xc06f82cd, which is the address of "clean_addr".
Examination of the System.map shows:

c06f22c8 D user_pmd_table
c06f22cc d __warned.19178
c06f22cd d clean_addr

indicating that a .data.unlikely section has appeared just before the
.data section from proc-xscale.S.  According to objdump -h, it appears
that our assembly files default their .data alignment to 2**0, which
is bad news if the preceding .data section size is not power-of-2
aligned at link time.

Add the appropriate .align directives to all assembly files in arch/arm
that are missing them where we require an appropriate alignment.

ARM: rockchip: select ARCH_DMA_ADDR_T_64BIT for LPAE

2017-08-06T11:06:05+00:00

Rockchip RK3288 has some 64-bit capable DMA and therefore needs
dma_addr_t to be a 64-bit size. One user is the Mali GPU.

ARM: rockchip: enable ZONE_DMA for non 64-bit capable peripherals

2017-07-31T22:57:59+00:00

Most IP cores on ARM Rockchip platforms can only address 32 bits of
physical memory for DMA. Thus ZONE_DMA should be enabled when LPAE
is activated.

ARM: rockchip: explicitly request exclusive reset control in smp code

2017-07-20T20:26:26+00:00

Commit a53e35db70d1 ("reset: Ensure drivers are explicit when requesting
reset lines") started to transition the reset control request API calls
to explicitly state whether the driver needs exclusive or shared reset
control behavior. Convert all drivers requesting exclusive resets to the
explicit API call so the temporary transition helpers can be removed.

No functional changes.

2017-07-04T21:34:51+00:00

Pull ARM SoC platform updates from Arnd Bergmann:
 "SoC platform changes (arch/arm/mach-*). This merge window, the bulk is
  for a few platforms:

   - Andres Färber adds initial support for the Actions Semi S500 (aka
     'owl') platform, a close relative of the S900 platform he adds for
     arm64.

   - in mach-omap2, we remove more legacy code

   - Rockchips gains support for the RV1108 SoC designed for camera
     applications.

   - For Atmel, we gain support for MMU-less SoCs (SAME70/V71/S70/V70)

   - Minor updates for other platforms, including davinci, s3c64xx,
     prima2, stm32, broadcom nsp, amlogic, pxa, imx and renesas"

clocksource/drivers: Rename clocksource_probe to timer_probe

2017-06-14T09:59:16+00:00

The function name is now renamed to 'timer_probe' for consistency with
the CLOCKSOURCE_OF_DECLARE => TIMER_OF_DECLARE change.
