* drm/gma500: Make I2C terminology more inclusiveEaswar Hariharan2024-07-291-2/+2
| | | | | | | | | | | | I2C v7, SMBus 3.2, and I3C 1.1.1 specifications have replaced "master/slave" with more appropriate terms. Inspired by Wolfram's series to fix drivers/i2c/, fix the terminology for users of I2C_ALGOBIT bitbanging interface, now that the approved verbiage exists in the specification.

* drm/gma500/intel_bios.h: Replace zero-length array with flexible-array memberGustavo A. R. Silva2020-03-061-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.

* | drm/gma500: drop drmP.h from header filesSam Ravnborg2019-05-221-2/+1
|/ | | | | | | | | | | | | | | | Drop use of drmp.h from all header files in drm/gma500. Fix fallout in all files. In some cases moved include lines and sorted them too. With drmP.h removed from all header files it can now be removed from each .c file without any further dependencies Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Cc: Patrik Jakobsson <patrik.r.jakobsson@gmail.com> Cc: David Airlie <airlied@linux.ie> Cc: Daniel Vetter <daniel@ffwll.ch> Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Patrik Jakobsson <patrik.r.jakobsson@gmail.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190519195526.3422-3-sam@ravnborg.org

* gma500/cdv: Add eDP supportZhao Yakui2012-08-241-0/+46
| | | | | | | | | | | | | | | | Introduce the eDP support into the driver. This has been reworked a bit because kernel driver proper uses encoder/connectors while the legacy Intel driver uses the old output stuff. It also diverges on the backlight handling. The legacy Intel driver adds a panel abstraction based upon the i915 one. It's only really used for backlight bits and we have a perfectly good backlight abstraction which can extend instead.

| | | | | | | | | | These are unintuitive. These are type bool and return -1 casted to true on failure. Let's just make it return an int. The callers don't care, but let's change this as a cleanup.
