Currently, the interrupt lines requested by Panfrost use unmeaningful names, which adds some obscurity to interrupt introspection (i.e. any tool based on procfs' interrupts file). In order to improve this, prefix each requested interrupt with the module name: panfrost-{gpu,job,mmu}. Signed-off-by:Ezequiel Garcia <ezequiel@collabora.com> Reviewed-by:

Explicit management of the GPU's core stacks is only necessary in the case of a broken integration with the PDC. Since there are no known platforms which have such a broken integration let's remove the explicit control from the driver since this apparently causes problems on other platforms and will have a small performance penality. The out of tree mali_kbase driver contains this text regarding controlling the core stack (CONFIGMALI_CORESTACK): Enabling this feature on supported GPUs will let the driver powering on/off the GPU core stack independently without involving the Power Domain Controller. This should only be enabled on platforms which integration of the PDC to the Mali GPU is known to be problematic. This feature is currently only supported on t-Six and t-HEx GPUs. If unsure, say N.

Add support for the Okaya RH128128T display to the st7735r driver on DT-enabled systems. The RH128128T is a 128x128 1.44" TFT display driven by a Sitronix ST7715R TFT Controller/Driver. The latter is very similar to the ST7735R, and can be handled by the existing st7735r driver. Signed-off-by:

Currently the st7735r driver supports only a single display panel. Prepare for adding support for other display panels by factoring out the display-specific parameters in struct st7735r_cfg. For now, the following parameters can be configured: - Display resolution, - Horizontal/vertical display offsets, - Read-write versus read-only controllers, - RGB versus BGR color component ordering. Rename jd_t18003_t01_pipe_enable() and jd_t18003_t01_pipe_funcs() to st7735r_pipe_enable() resp. st7735r_pipe_funcs(), as they are not really specific to the Jianda JD-T18003-T01 display anymore.

If the resolution of the TFT display is smaller than the maximum resolution supported by the display controller, the display may be connected to the driver output arrays with a horizontal and/or vertical offset, leading to a shifted image. Add support for specifying these offsets. Signed-off-by:

Document support for the Okaya RH128128T display, which is a 128x128 1.44" TFT display driven by a Sitronix ST7715R TFT Controller/Driver. It can be found on e.g. the Renesas YRSK-LCD-PMOD extension board, which comes with various Renesas development kits (e.g. Renesas Starter Kit+ for RZ/A1H[1]). ST7715R and ST7735R are very similar. Their major difference is that the former is restricted to displays of up to 132x132 pixels, while the latter supports displays up to 132x162 pixels.
