2011-11-10ENGR00160878-2 mxc v4l2 output: new mxc v4l2 output driver based on videobufJason Chen
This new v4l2 output driver is based on videobuf, using dma contig alloc method. It creates video dev node for each display framebuffer begin from /dev/video16 by default. If need post-processing, this driver will do it by ipu pp driver which support: - resizing - CSC - rotate - deinterlacing If no need post-processing, the IPU IC will be bypassed as old driver, the buf will be set to fb buffer directly by crack fb smem_start. The user should do setting before streamon like below: 1. set output crop 2. set ctrl like rotate/vflip/hflip/deinterlacing motion 3. set fmt 4. reqbuf The new features compare to old driver: - support multi-instance - support user point buffer - runtime suspend/resume For suspend/resume, still has chance to meet issue on mx6q, will fix later.

2011-11-10Fix memory leak in cpufreq_statsteven finney
commit 98586ed8b8878e10691203687e89a42fa3355300 upstream. When a CPU is taken offline in an SMP system, cpufreq_remove_dev() nulls out the per-cpu policy before cpufreq_stats_free_table() can make use of it. cpufreq_stats_free_table() then skips the call to sysfs_remove_group(), leaving about 100 bytes of sysfs-related memory unclaimed each time a CPU-removal occurs. Break up cpu_stats_free_table into sysfs and table portions, and call the sysfs portion early.

2011-11-10CPU hotplug, re-create sysfs directory and symlinksJacob Shin
commit 27ecddc2a9f99ce4ac9a59a0acd77f7100b6d034 upstream. When we discover CPUs that are affected by each other's frequency/voltage transitions, the first CPU gets a sysfs directory created, and rest of the siblings get symlinks. Currently, when we hotplug off only the first CPU, all of the symlinks and the sysfs directory gets removed. Even though rest of the siblings are still online and functional, they are orphaned, and no longer governed by cpufreq. This patch, given the above scenario, creates a sysfs directory for the first sibling and symlinks for the rest of the siblings. Please note the recursive call, it was rather too ugly to roll it out. And the removal of redundant NULL setting (it is already taken care of near the top of the function).

2011-11-10serial/imx: read cts state only after acking cts change irqUwe Kleine-König
commit 5680e94148a86e8c31fdc5cb0ea0d5c6810c05b0 upstream. If cts changes between reading the level at the cts input (USR1_RTSS) and acking the irq (USR1_RTSD) the last edge doesn't generate an irq and uart_handle_cts_change is called with a outdated value for cts. The race was introduced by commit ceca629 ([ARM] 2971/1: i.MX uart handle rts irq) Reported-by: Arwed Springer <Arwed.Springer@de.trumpf.com> Tested-by: Arwed Springer <Arwed.Springer@de.trumpf.com> Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de> (cherry picked from commit 1eb710f4e01a9afab735828c87ef13e2e6b57386)
2011-11-10ENGR00161256-1 flexcan: convert driver to use platform idsDong Aisheng
Using platform ids to handle differences between different SoCs. The default rx fifo global mask register, newly introduced in mx6q, is 0xffffffff and the reset value in Message buffers(can be reused as the memory of rx fifo filter table) is none zero, it will wrongly cause the can to be unable to recevie packets due to filter. We need to clear it to make sure to receive all packets. Signed-off-by: Dong Aisheng <b29396@freescale.com>

2011-11-10ENGR00160692 - MXC HDMI: Unbalanced clk disableDanny Nold
HDMI IAHB clock was capable of being disabled twice consecutively due to a race condition between enabling the HDMI interrupts and disabling the HDMI clock. A spinlock has been added to protect against the race condition. Another race condition was present due to the driver handling HPD (hotplug detect) and RX Sense interrupts separately. Only HPD interrupts handled now, simplifying enable/disable flow and eliminating the race condition. One final race condition fixed during HDMI driver initialization. IRQ request moved to after place where IAHB is disabled, to ensure balanced enable/disable of IAHB clock. Signed-off-by: Danny Nold <dannynold@freescale.com>
