The reset value for the MAX clock is 0b10.
The MAX clock is needed by the SoC, yet unused in the Kernel, so the
common clock framework will disable it during late init time. It will
only disable clocks though which it detects as being turned on. This
detection is made depending on the lower bit of the gate. If the reset
value has been altered by the bootloader to 0b11 the clock framework

off and the system locks up.

atmel_lcdfb: fix 16-bpp modes on older SOCs
Fix regression introduced by commit 787f9fd23283 ("atmel_lcdfb: support
16bit BGR:565 mode, remove unsupported 15bit modes") which broke 16-bpp
modes for older SOCs which use IBGR:555 (msb is intensity) rather
than BGR:565.
Use SOC-type to determine the pixel layout.
Tested on at91sam9263 and at91sam9g45.

We can now enable mach-spear without selecting any of the

Doing so causes a build error that is trivial to fix by
making both the spear13xx and the spear3xx/6xx portion of
this file conditional rather than alternatives.

The spear platform is now multiplatform capable in principle,

the Kconfig options for spear to enable both single- and multiplatform
support. As a side-effect, even building the single spear kernel
can now enable spear3xx and spear6xx simultaneously, although
not together with spear13xx, because they are a different archicture
version (v7 instead of v5).

it static, since that one does not actually need to be

Device drivers should not access MMIO registers through hardcoded

Ideally, the clock driver would use of_iomap() or similar to
get the address, and that can be used later, but for now, this

This adds additional error checking to the private edma api implementation
to catch the case where the edma_alloc_slot() has an invalid controller

being handled in order to avoid setting up a second edma dmaengine
instance on DA830.
Verfied using a DA850 with the second EDMA controller platform instance
removed to simulate a DA830 which only has a single EDMA controller.

Atmel MXT touchscreen: increase reset timeouts
There is a more complete atmel patch-series out by Nick Dyer that fixes

get the touchscreen going on (at least my) Pixel Chromebook.
Not that I want my dirty fingers near that beautiful screen, but it
seems that a non-initialized touchscreen will also end up being a
constant wakeup source, so you have to disable it to go to sleep. And
it's easier to just fix the initialization sequence.
Update proc_ns_follow_link to use nd_jump_link instead of just
manually updating nd.path.dentry.
This fixes the BUG_ON(nd->inode != parent->d_inode) reported by Dave
Jones and reproduced trivially with mkdir /proc/self/ns/uts/a.
Sigh it looks like the VFS change to require use of nd_jump_link
happend while proc_ns_follow_link was baking and since the common case
of proc_ns_follow_link continued to work without problems the need for
making this change was overlooked.
