drm: ast: remove dead code and pointless local lut storage

2017-08-04T09:35:39Z

The redundant fb helpers .load_lut, .gamma_set and .gamma_get are no longer used. Remove the dead code and hook up the crtc .gamma_set to use the crtc gamma_store directly instead of duplicating that info locally.

drm/ast: Actually load DP501 firmware when required

2017-08-02T02:13:16Z

The ast driver has a code to load the DP501 firmware, but it's never used. This patch implements its actual usage by requesting the firmware on demand, and release the firmware at exit as well. Also the path contains a few cleanups and makes relevant functions static. Signed-off-by: Egbert Eich Signed-off-by: Takashi Iwai Signed-off-by: Dave Airlie

drm/ast: Base support for AST2500

2017-02-28T03:15:14Z

Add detection and mode setting updates for AST2500 generation chip, code originally from Aspeed and slightly reworked for coding style mostly by Ben. This doesn't contain the BMC DRAM POST code which is in a separate patch. Signed-off-by: Y.C. Chen Signed-off-by: Benjamin Herrenschmidt Acked-by: Joel Stanley Signed-off-by: Dave Airlie

drm/ast: Handle configuration without P2A bridge

2017-02-28T03:09:50Z

The ast driver configures a window to enable access into BMC memory space in order to read some configuration registers. If this window is disabled, which it can be from the BMC side, the ast driver can't function. Closing this window is a necessity for security if a machine's host side and BMC side are controlled by different parties; i.e. a cloud provider offering machines "bare metal". A recent patch went in to try to check if that window is open but it does so by trying to access the registers in question and testing if the result is 0xffffffff. This method will trigger a PCIe error when the window is closed which on some systems will be fatal (it will trigger an EEH for example on POWER which will take out the device). This patch improves this in two ways: - First, if the firmware has put properties in the device-tree containing the relevant configuration information, we use these. - Otherwise, a bit in one of the SCU scratch registers (which are readable via the VGA register space and writeable by the BMC) will indicate if the BMC has closed the window. This bit has been defined by Y.C Chen from Aspeed. If the window is closed and the configuration isn't available from the device-tree, some sane defaults are used. Those defaults are hopefully sufficient for standard video modes used on a server.

Merge tag 'v4.10-rc8' into drm-next

Linux 4.10-rc8 Backmerge Linus rc8 to fix some conflicts, but also to avoid pulling it in via a fixes pull from someone.

drm/ast: Fixed system hanged if disable P2A

2017-01-27T00:40:03Z

The original ast driver will access some BMC configuration through P2A bridge that can be disabled since AST2300 and after. It will cause system hanged if P2A bridge is disabled. Here is the update to fix it. Signed-off-by: Y.C. Chen Signed-off-by: Dave Airlie

drm: Change the return type of the unload hook to void

2017-01-09T10:25:22Z

The integer returned by the unload hook is ignored by the drm core, so let's make it void. This patch was created using the following Coccinelle semantic script (except for the declaration and comment in drm_drv.h): Compile-tested only. // @ get_name @ struct drm_driver drv; identifier fn; @@ drv.unload = fn; @ replace_type @ identifier get_name.fn; @@ - int + void fn (...) { ... } @ remove_return_param @ identifier get_name.fn; @@ void fn (...) { <... if (...) return - ... ; ...> } @ drop_final_return @ identifier get_name.fn; @@ void fn (...) { ... - return 0; } // Suggested-by: Daniel Vetter Signed-off-by: Gabriel Krisman Bertazi Acked-by: Christian König .

drm: Don't include in

2016-12-18T10:59:29Z

used to define most of the in-kernel KMS API. It has now been split into separate files for each object type, but still includes most other KMS headers to avoid breaking driver compilation. As a step towards fixing that problem, remove the inclusion of from and include it instead where appropriate. Also remove the forward declarations of the drm_encoder and drm_encoder_helper_funcs structures from as they're not needed in the header. now has to include and contain a forward declaration of struct drm_encoder in order to allow including it as the first header in a compilation unit.
