SiS_DRAMType is const and only used by sisfb_post_300_rwtest which is marked __devinit we can annotate SiS_DRAMType with __devinitconst and move it into the file scope in order to not have it created on the stack. This patch decreases the compiled module size by about 100bytes. And since hardcoded values are bad we use ARRAY_SIZE for determining the size of SiS_DRAMType ;) Signed-off-by:

This patch removes the unused structs SiS_SDRDRAM_TYPE and SiS_DDRDRAM_TYPE from init.h These are not used anywhere so we can delete them. The SiS_DRAMType is identically defined in sis_main.c and only used there so we can remove it here. Signed-off-by:

Since s3c_fb_missing_pixclock() is called from s3c_fb_set_rgb_timing() which is used in the suspend/resume paths it can't be marked __devinit as this could result in it being discarded after boot. Signed-off-by:

The AUO-K190X controllers share a very similar set of commands and can therefore also share most of the driver code. Signed-off-by:

Heiko Stübner authored
With this optional callback the driver is notified when the first page is entered into the pagelist and a new deferred_io call is scheduled. A possible use-case for this is runtime-pm. In the first_io call pm_runtime_get() could be called, which starts an asynchronous runtime_resume of the device. In the deferred_io callback a call to pm_runtime_barrier() makes the sure, the device is resumed by then and a pm_runtime_put() may put the device back to sleep. Also, some SoCs may use the runtime-pm system to determine if they are able to enter deeper idle states. Therefore it is necessary to keep the use-count from the first written page until the conclusion of the screen update, to prevent the system from going to sleep before completing the pending update. Two users of defio were using kmalloc to allocate the structure. These allocations are changed to kzalloc, to prevent uninitialised .first_io members in those drivers. Signed-off-by:

There were two problems in this code: failure of the setup function should free locally allocated resources like other nearby failures, and the test if (&info->cmap) can never be false. To generally clean things up, this patch reorders the error handling code at the failed label and adds labels so that the conditionals are not necessary. Signed-off-by:

This patch adds analog and pll control setting. This control setting is used for DP TX PHY block to set the values as below. It is beneficial to improve analog characteristics. - TX terminal registor is 50 Ohm. - Reference clock of PHY is 24 MHz. - Power source for TX digital logic is 1.0625 V. - Power source for internal clock driver is 1.0625 V. - PLL VCO range setting is 600 uA. - Power down ring osc is turned off. - AUX terminal resistor is 50 Ohm. - AUX channel current is 8 mA and multiplied by 2. - TX channel output amplitude is 400 mV.

For all the Samsung SoC based boards which have the platform data for s3c-fb driver, the 'default_win' element in the platform data is removed and the lcd panel video timing values are moved out of individual window configuration data. Acked-by:

Thomas Abraham authored
The display controller window data should contain window configuration data for only one type of lcd panel. So, for real6410 and mini6410 boards, split the existing display controller window data, which contains window configuration data for two different types of lcd panels, into two seperate instances and register one of them depending on the type of the lcd panel detected at runtime. This is a prerequisite change for a subsequent commit that reorders the platform data of display controller by moving video interface timing out of window setup data.

Thomas Abraham authored
The decision to enable or disable the data output to the lcd panel from the controller need not be based on the value of 'default_win' element in the platform data. Instead, the data output to the panel is enabled if any of the windows are active, else data output is disabled. Cc: Ben Dooks <ben-linux@fluff.org> Signed-off-by:
-
Thomas Abraham authored
The video interface timing is independent of the window setup data. The resolution of the window can be smaller than that of the lcd panel to which the video data is output. So move the video timing data from the per-window setup data to the platform specific section in the platform data. This also removes the restriction that atleast one window should have the same resolution as that of the panel attached. Cc: Ben Dooks <ben-linux@fluff.org> Signed-off-by:

Add abort flag and use it to terminate processing when an exchange is timed out or is reset. The abort flag is used in place of the transport_generic_free_cmd function call in the reset and timeout cases, because calling that function in that context would free memory that was in use. The aborted flag allows the lifetime to be managed in a more normal way, while truncating the processing. This change eliminates a source of memory corruption which manifested in a variety of ugly ways. (nab: Drop unused struct fc_exch *ep in ft_recv_seq) Signed-off-by:
