Verifying if the size of memory allocation in ion_alloc() is aligned by PAGE_SIZE at least. If it is not, this change makes the size to be aligned by PAGE_SIZE. 2. Unmaps all mappings to the kernel and DMA address spaces when destroying ion_buffer in ion_buffer_destroy(). This prevents leaks in those virtual address spaces. 3. Makes the return value of ion_alloc() to be explicit Linux error code when it fails to allocate a buffer. 4. Makes ion_alloc() implementation simpler. Removes 'goto' statement and relavant call to ion_buffer_put(). 5. Checks if the task is valid before calling put_task_struct() due to failure on creating a ion client in ion_client_create(). 6. Returns error when buffer allocation requested by userspace is failed.

| * gxt4500: enable panningOndrej Zary2015-10-08
| | | | | | | | | | | | | | | | | | | | The driver implements pan_display but the corresponding flags are not set. Add FBINFO_HWACCEL_XPAN and FBINFO_HWACCEL_YPAN to flags to allow HW accelerated panning (for fast scrolling).

| * gxt4500: Use arch_phys_wc_* for framebufferOndrej Zary2015-10-08
| | | | | | | | | | | | | | Add arch_phys_wc_* calls to allow write-combining using MTRR. Signed-off-by: Ondrej Zary <linux@rainbow-software.org> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
| * gxt4500: fix color orderOndrej Zary2015-10-08
| | | | | | | | | | | | | | | | | | | | | | The color order in truecolor modes is wrong. This does not affect console but is visible e.g. in X11 which has wrong colors. Swap blue and red colors to fix the problem.

| * gxt4500: enable on non-PPC architecturesOndrej Zary2015-10-08
| | | | | | | | | | | | | | | | | | | | | | These chips can be present at least on x86 too - Fire GL2 AGP has GXT6000P but this driver is currently limited to PPC. Enable it for all architectures and add chip configuration for little-endian. Tested on x86 with Fire GL2 AGP.

| | | | | | | | | | | | | | | | | | | | i2c-algo-bit allows I2C adapters without SCL read capability to work but fb_ddc_read fails to work on them. Fix fb_ddc_read to work with I2C adapters not capable of reading SCL. Signed-off-by: Ondrej Zary <linux@rainbow-software.org> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
| * fbdev: ssd1307fb: add ssd1309 supportOlliver Schinagl2015-09-24
| | | | | | | | | | | | | | | | | | | | | | | | The ssd1307fb driver supports a lot of chips from the ssd130xfb series. This patch adds the ssd1309 chip, a 128x64 OLED driver chip. It is very similar to the other chips and only has some definitions added to support it.
