2013-10-29imx-drm: ipuv3-crtc: Invert IPU DI0 clock polarityFabio Estevam1-1/+1
sig_cfg.clk_pol controls the 'di0_polarity_disp_clk' bit of register IPUx_DI0_GENERAL through the following code in imx-drm/ipu-v3/ipu-di.c: if (!sig->clk_pol) di_gen |= DI_GEN_POLARITY_DISP_CLK; With 'di0_polarity_disp_clk' bit set we do not have stable HDMI output on mx6solo: contours of pictures look jittery and the white colour does not appear really white. Russell King initially reported this problem at: http://www.spinics.net/lists/arm-kernel/msg279805.html Inverting 'di0_polarity_disp_clk' leads to stable HDMI output image. Tested on the following boards: - mx6solowandboard (HDMI output) - mx6qwandboard (HDMI output) - mx6qsabrelite (LVDS) - mx6qsabresd (HDMI output and LVDS) - mx6dlsabresd (HDMI output) - mx53qsb (parallel WVGA display) Reported-by: Russell King <[email protected]> Suggested-by: Sascha Hauer <[email protected]> Signed-off-by: Fabio Estevam <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>
2013-10-29usb: cdc-wdm: ignore speed change notificationsBjørn Mork1-0/+4
The only notification supported by the Device Management class is Response Available. But this driver is also used as a subdriver of other CDC classes, allowing notifications like Speed Change and Network Connection. This results in log messages which are only confusing to an end user: [66255.801874] cdc_mbim 1-3:1.5: unknown notification 42 received: index 5 len 8 These drivers use cdc-wdm as a subdriver to allow access to an embedded management protocol, and all management is expected to use this protocol. There is therefore no need to handle any of these optional CDC notifications. Instead we can let the cdc-wdm driver recognize them and log a debug level message instead of an error.

suppressed" messages pr_debug_ratelimited should be coded similarly to dev_dbg_ratelimited to reduce the "callbacks suppressed" messages. Add #include <linux/dynamic_debug.h> to printk.h. Unfortunately, this new #include must be after the prototype/declaration of function printk. It may be better to split out these _ratelimited declarations into a separate file one day. Any use of these pr_<foo>_ratelimited functions must also have another specific #include <ratelimited.h>. Most users have this done indirectly via #include <linux/kernel.h> printk.h may not #include <linux/ratelimit.h> as it causes circular dependencies and compilation failures.

2013-10-29serial: omap: Add support for optional wake-upTony Lindgren1-8/+46
With the recent pinctrl-single changes, omaps can treat wake-up events from deeper idle states as interrupts. There's a separate "io chain" controller on most omaps that stays enabled when the device hits off-idle and the regular interrupt controller is powered off. Let's add support for the optional second interrupt for wake-up events. And then serial-omap can manage the wake-up interrupt from it's runtime PM calls to avoid spurious interrupts during runtime. Note that the wake interrupt is board specific as it uses the UART RX pin, and for omap3, there are six pin options for UART3 RX pin. Also Note that the legacy platform based booting handles the wake-ups in the legacy mux driver and does not need to pass the wake-up interrupt to the driver. And finally, to pass the wake-up interrupt in the dts file, either interrupt-map or the pending interrupts-extended property needs to be passed. It's probably best to use interrupts-extended when it's available.

3124eb1679 ("sysfs: merge regular and bin file handling") folded bin file handling into regular file handling. Among other things, bin file now shares the same open path including sysfs_open_dirent association using sysfs_dirent->s_attr.open. This is buggy because ->s_bin_attr lives in the same union and doesn't have the field. This bug doesn't trigger because sysfs_elem_bin_attr doesn't have an active field at the conflicting position. It does have a field "buffers" but it isn't used anymore. This patch collapses sysfs_elem_bin_attr into sysfs_elem_attr so that the bin_attr is accessed through ->s_attr.bin_attr which lives with ->s_attr.attr in an anonymous union. The code paths already assume bin_attr contains attr as the first element, so this doesn't add any more assumptions while making it explicit that the two types are handled together.
