2012-09-23viafb: don't touch clock state on OLPC XO-1.5Daniel Drake1-0/+19
As detailed in the thread titled "viafb PLL/clock tweaking causes XO-1.5 instability," enabling or disabling the IGA1/IGA2 clocks causes occasional stability problems during suspend/resume cycles on this platform. This is rather odd, as the documentation suggests that clocks have two states (on/off) and the default (stable) configuration is configured to enable the clock only when it is needed. However, explicitly enabling *or* disabling the clock triggers this system instability, suggesting that there is a 3rd state at play here. Leaving the clock enable/disable registers alone solves this problem. This fixes spurious reboots during suspend/resume behaviour introduced by commit b692a63a.

equalization To check channel equalization, the value of LANE_ALIGN_STATUS_UPDATED is necessary in exynos_dp_channel_eq_ok(). Also, link_align includes this value. However, link_status does not include this value, so it makes the problem that channel equalization is failed during link training.

It is expected that LCDC to continue to be disabled after resume if it is blanked before suspend. This is also true for DVFS. But it is observed that LCDC being enabled after suspend/resume cycle or DVFS. Correcting it by having check for FB_BLANK_UNBLANK before enabling.

2012-08-23OMAPDSS: Fix SDI PLL lockingTomi Valkeinen1-0/+14
Commit f476ae9dab3234532d41d36beb4ba7be838fa786 (OMAPDSS: APPLY: Remove DISPC writes to manager's lcd parameters in interface) broke the SDI output, as it causes the SDI PLL locking to fail. LCLK and PCLK divisors are located in shadow registers, and we normally write them to DISPC registers when enabling the output. However, SDI uses pck-free as source clock for its PLL, and pck-free is affected by the divisors. And as we need the PLL before enabling the output, we need to write the divisors early. It seems just writing to the DISPC register is enough, and we don't need to care about the shadow register mechanism for pck-free. The exact reason for this is unknown.

2012-08-22fbcon: fix race condition between console lock and cursor timer (v1.1)Dave Airlie1-1/+8
So we've had a fair few reports of fbcon handover breakage between efi/vesafb and i915 surface recently, so I dedicated a couple of days to finding the problem. Essentially the last thing we saw was the conflicting framebuffer message and that was all. So after much tracing with direct netconsole writes (printks under console_lock not so useful), I think I found the race. Thread A (driver load) Thread B (timer thread) unbind_con_driver -> | bind_con_driver -> | vc->vc_sw->con_deinit -> | fbcon_deinit -> | console_lock() | | | | fbcon_flashcursor timer fires | console_lock() <- blocked for A | | fbcon_del_cursor_timer -> del_timer_sync (BOOM) Of course because all of this is under the console lock, we never see anything, also since we also just unbound the active console guess what we never see anything. Hopefully this fixes the problem for anyone seeing vesafb->kms driver handoff. v1.1: add comment suggestion from Alan. Cc: stable@vger.kernel.org Signed-off-by: Dave Airlie <airlied@redhat.com>

git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs Pull second vfs pile from Al Viro: "The stuff in there: fsfreeze deadlock fixes by Jan (essentially, the deadlock reproduced by xfstests 068), symlink and hardlink restriction patches, plus assorted cleanups and fixes. Note that another fsfreeze deadlock (emergency thaw one) is *not* dealt with - the series by Fernando conflicts a lot with Jan's, breaks userland ABI (FIFREEZE semantics gets changed) and trades the deadlock for massive vfsmount leak; this is going to be handled next cycle. There probably will be another pull request, but that stuff won't be in it."

Merge Andrew's first set of patches: "Non-MM patches: - lots of misc bits - tree-wide have_clk() cleanups - quite a lot of printk tweaks. I draw your attention to "printk: convert the format for KERN_<LEVEL> to a 2 byte pattern" which looks a bit scary. But afaict it's solid. - backlight updates - lib/ feature work (notably the addition and use of memweight()) - checkpatch updates - rtc updates - nilfs updates - fatfs updates (partial, still waiting for acks) - kdump, proc, fork, IPC, sysctl, taskstats, pps, etc - new fault-injection feature work" * Merge emailed patches from Andrew Morton <akpm@linux-foundation.org>: (128 commits) drivers/misc/lkdtm.c: fix missing allocation failure check lib/scatterlist: do not re-write gfp_flags in __sg_alloc_table() fault-injection: add tool to run command with failslab or fail_page_alloc fault-injection: add selftests for cpu and memory hotplug powerpc: pSeries reconfig notifier error injection module memory: memory notifier error injection module PM: PM notifier error injection module cpu: rewrite cpu-notifier-error-inject module fault-injection: notifier error injection c/r: fcntl: add F_GETOWNER_UIDS option resource: make sure requested range is included in the root range include/linux/aio.h: cpp->C conversions fs: cachefiles: add support for large files in filesystem caching pps: return PTR_ERR on error in device_create taskstats: check nla_reserve() return sysctl: suppress kmemleak messages ipc: use Kconfig options for __ARCH_WANT_[COMPAT_]IPC_PARSE_VERSION ipc: compat: use signed size_t types for msgsnd and msgrcv ipc: allow compat IPC version field parsing if !ARCH_WANT_OLD_COMPAT_IPC ipc: add COMPAT_SHMLBA support ...
2012-07-31backlight: move lp855x header into platform_data directoryKim, Milo1-1/+1
The lp855x header is used only in the platform side, so it can be moved into platform_data directory Signed-off-by: Milo(Woogyom) Kim <milo.kim@ti.com> Cc: Richard Purdie <rpurdie@rpsys.net> Cc: Bryan Wu <bryan.wu@canonical.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2012-07-31backlight: move register definitions from header to sourceKim, Milo1-2/+6
ROM boundary definitions do not need to be exported because these are used only internally in the lp855x driver. And few code cosmetic changes Signed-off-by: Milo(Woogyom) Kim <milo.kim@ti.com> Cc: Richard Purdie <rpurdie@rpsys.net> Cc: Bryan Wu <bryan.wu@canonical.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

The devm_ functions allocate memory that is released when a driver detaches. This patch uses devm_gpio_request_one() for these functions.
