2015-10-24Staging: xgifb: Replace udelay, mdelay functions with usleep_rangeNavya Sri Nizamkari
This patch fixes the checkpatch.pl check: CHECK: usleep_range is preferred over udelay. Replace mdelay with usleep_range function too. Add 1 millisecond to the delay time to get a reasonable upper limit which saves one wakeup call. Do same throughout the file.

2013-05-17staging/xgifb: Remove dead assignments/incrementsPeter Huewe
The code now contains several dead assignments which are shadowed by another assignment a few lines later. -> This patch removes them (and possibly associated code). Signed-off-by: Peter Huewe <peterhuewe@gmx.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-05-16staging/xgifb: Remove unnecessary binary calculation in GetXG27FPBitsPeter Huewe

2013-05-16staging/xgifb: Consolidate function almost identical calls in ↵Peter Huewe
XGINew_GetXG21Sense Instead of calling xgifb_reg_and_or with almost identical parameters in a simple if/else scenario, we assign the changing parameter to a temp variable and call xgifb_reg_and_or only from one location. -> Easier to read, easier to understand (especially wrt the line breaks) (For the if condition we don't need the Temp variable, so we can use the value directly).

2013-05-16staging/xgifb: Remove unnecessary cases in XGINew_SenseLCDPeter Huewe
The switch statement sets the temp value to zero for certain cases and leaves it untouched for other cases -> all these other cases can be combined in the default case. Since an empty case containing only a break, it can be removed. The patch also removes the if statement, as it uses the same value as the switch for comparison, and includes the code into the switch.

2013-05-16staging/xgifb: Remove uneccessary/simply if in XGINew_GetXG20DRAMTypePeter Huewe

MCLKData does not contain any 0x1C value for its field SR28 nor does XGI340_ECLKData contain any 0x1C or 0x22 value for its field SR2E. -> the statement always evaluates to false. -> remove Signed-off-by: Peter Huewe <peterhuewe@gmx.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2013-02-05staging/xgifb: Remove unused variablePeter Huewe
After the patch 'staging/xgifb: Don't write the same values x times' the local variable i is unused, which leads to the following warning: driverrs/staging/xgifb/vb_init.c: In function ‘XGINew_SetDRAMDefaultRegister340’: drivers/staging/xgifb/vb_init.c:433:43: warning: unused variable ‘i’ [-Wunused-variable] This patch fixes this Signed-off-by: Peter Huewe <peterhuewe@gmx.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-02-05staging/xgifb: Don't write the same values x timesPeter Huewe
With the previous patch 'Move duplicated code for dram to helper function' it becomes evident that the code is performing the same thing 4 or 8 times in a row without changing arguments to the function and thus writing the same values over and over again. It was tested that these repeats are unnecessary. -> we can safely remove them.

2013-02-05staging/xgifb: Replace XGI340_CR6B table with simple if/elsePeter Huewe
The XGI340_CR6B lookup table consists of the entries {0xaa, 0xaa, 0xaa, 0xaa} for an index <= 2 and {0x00, 0x00, 0x00, 0x00} for all other indices. The only user XGINew_SetDRAMDefaultRegister340 loops over these 4 values of a line with a for loop and since all entries are the same for each line we can simply replace the whole lookup table with a simple if/else assignment.

2012-09-13staging: xgifb: delete bogus video RAM configurationAaro Koskinen
The driver reconfigures DRAM size register to 8M (regardless what the actual size was) once the init has been completed, overwriting the correct value written during the early init. As a result if the driver is unloaded and reloaded, the user will be limited to 8M video memory and may lose some of the available video modes.
