2012-06-05video: bfin_adv7393fb: Convert to kstrtouint_from_userEmil Goode
This patch removes a call to the deprecated simple_strtoul function and simplifies the code by replacing two function calls with one call to kstrtouint_from_user. -Simplify the adv7393_write_proc function by replacing the simple_strtoul and copy_from_user calls with one call to kstrtouint_from_user. -Change the count parameter from unsigned long to size_t as this is the type that the kstrtouint_from_user function expects.

2012-06-04OMAPDSS: DSI: Fix bug when calculating LP command interleaving parametersArchit Taneja
In function dsi_compute_interleave_lp(), the escape clock/LP clock time period is calculated incorrectly. The escape clock/LP clock is calculated as: LP Clock(Hz) = DSI_FCLK(Hz) / lp_clk_div Since we are calculating the time period of LP clock, the LP clock divider should be multiplied with the time period of DSI_FCLK. Calculating incorrect value of txclkesc results in incorrect calculation of LP interleaving parameters, it also creates a possibility of a divide by zero error.

2012-06-04OMAPDSS: fix bogus WARN_ON in dss_runtime_put()Tomi Valkeinen
pm_runtime_put_sync() in dss_runtime_put() returns -EBUSY when any child of dss is still enabled. This happens, for example, when a display output is enabled and one dumps the clocks via debugfs. This causes dss_runtime_get & put to be called. While I couldn't find anything about this in the documentation and it wasn't immediately clear from runtime_pm code, it looks to me that pm_runtime_put_sync() returns -EBUSY to inform that things went fine, but the device could not be turned off as there are still child devices that are enabled. This is not a problem. This patch skips the WARN_ON if pm_runtime_put_sync() returns -EBUSY. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

2012-05-30i2c: Split I2C_M_NOSTART support out of I2C_FUNC_PROTOCOL_MANGLINGMark Brown
Since there are uses for I2C_M_NOSTART which are much more sensible and standard than most of the protocol mangling functionality (the main one being gather writes to devices where something like a register address needs to be inserted before a block of data) create a new I2C_FUNC_NOSTART for this feature and update all the users to use it. Also strengthen the disrecommendation of the protocol mangling while we're at it. In the case of regmap-i2c we remove the requirement for mangling as I2C_M_NOSTART is the only mangling feature which is being used.

2012-05-29lcd: add callbacks for early fb event blank supportInki Dae
This patchset adds early fb blank feature that a callback of lcd panel driver is called prior to specific fb driver's one. In the case of MIPI-DSI based video mode LCD Panel, for lcd power off, the power off commands should be transferred to lcd panel with display and mipi-dsi controller enabled because the commands is set to lcd panel at vsync porch period. and in opposite case, the callback of fb driver should be called prior to lcd panel driver's one because of same issue. Also if fb_blank mode is changed to FB_BLANK_POWERDOWN then display controller would be off(clock disable) but lcd panel would be still on. at this time, you could see some issue like sparkling on lcd panel because video clock to be delivered to ldi module of lcd panel was disabled. this issue could occurs for all lcd panels. The callback order is as the following: at fb_blank function of fbmem.c -> fb_notifier_call_chain(FB_EARLY_EVENT_BLANK) -> lcd panel driver's early_set_power() -> info->fbops->fb_blank() -> spcefic fb driver's fb_blank() -> fb_notifier_call_chain(FB_EVENT_BLANK) -> lcd panel driver's set_power() -> fb_notifier_call_chain(FB_R_EARLY_EVENT_BLANK) if info->fops->fb_blank() was failed. fb_notifier_call_chain(FB_R_EARLY_EVENT_BLANK) would be called to revert the effects of previous FB_EARLY_EVENT_BLANK call. and note that if early_set_power() of lcd_ops is NULL then early fb blank callback would be ignored. This patch: Add early_set_power and r_early_set_power callbacks. early_set_power callback is called prior to fb_blank() of fbmem.c and r_early_set_power callback is called if fb_blank() was failed to revert the effects of the early_set_power call of lcd panel driver.

2012-05-29fbdev: add events for early fb event supportInki Dae
Add FB_EARLY_EVENT_BLANK and FB_R_EARLY_EVENT_BLANK event mode supports. first, fb_notifier_call_chain() is called with FB_EARLY_EVENT_BLANK and fb_blank() of specific fb driver is called and then fb_notifier_call_chain() is called with FB_EVENT_BLANK again at fb_blank(). and if fb_blank() was failed then fb_nitifier_call_chain() would be called with FB_R_EARLY_EVENT_BLANK to revert the previous effects.

2012-05-29blacklight: remove redundant spi driver bus initializationLars-Peter Clausen
In ancient times it was necessary to manually initialize the bus field of an spi_driver to spi_bus_type. These days this is done in spi_driver_register() so we can drop the manual assignment. The patch was generated using the following coccinelle semantic patch: // <smpl> @@ identifier _driver; @@ struct spi_driver _driver = { .driver = { - .bus = &spi_bus_type, }, }; // </smpl> Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Cc: Richard Purdie <rpurdie@rpsys.net> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2012-05-29video: bfin_adv7393fb: Fix cleanup codeEmil Goode
This patch fixes the cleanup code of the bfin_adv7393_fb_probe function. 1) The resources were not freed in the order that we allocated them so we call dma_free_coherent() before it was allocated. 2) The labels weren't in the right place which also meant that we freed resources that weren't allocated. 3) We should free gpio_free(P_IDENT(P_PPI0_FS3)) before returning. 4) Lets change the label names into something more meaningful.
