[PATCH 1/2] ARC: [plat-axs10x]: use pgu pll instead of fixed clock

Use PLL driver instead of fixed-clock for PGU pixel clock. That allows us to support wider range of graphic modes. Signed-off-by: Eugeniy Paltsev --- arch/arc/boot/dts/axs10x_mb.dtsi | 11 ++- 1 file changed, 6 insertions(+), 5 deletions(-) diff --git a/arch/arc/boot/dts/axs10x_mb.dtsi

[PATCH 2/2] ARC: [plat-axs10x]: remove hardcoded video mode from bootargs

Now have pixel clock PLL driver and we can change pixel clock rate so we don't need to enforce one exact video mode. Moreover enforcing video mode is harmful in case of we enforce mode which isn't supported by the monitor we are using. Signed-off-by: Eugeniy Paltsev --- arch/arc/boot/dts/axs101.

[PATCH 3/4] DRM: ARC: PGU: replace unsupported by HW RGB888 format by XRGB888

ARC PGU doesn't support RGB888 (24 bit) format but supports XRGB888 (32 bit) format. Fix incorrect format list in a driver. Signed-off-by: Eugeniy Paltsev --- drivers/gpu/drm/arc/arcpgu_crtc.c | 6 +++--- drivers/gpu/drm/arc/arcpgu_regs.h | 2 +- 2 files changed, 4 insertions(+), 4 deletions(-)

Current implementation don't switch to RGB565 format if BGR888 was previously used. Fix that. Signed-off-by: Eugeniy Paltsev --- drivers/gpu/drm/arc/arcpgu_crtc.c | 12 +++- 1 file changed, 7 insertions(+), 5 deletions(-) diff --git a/drivers/gpu/drm/arc/arcpgu_crtc.c b/drivers/gpu/drm

[PATCH 4/4] DRM: ARC: PGU: add ARGB8888 format to supported format list

As we ignore first 8 bit of 32 bit pixel value we can add ARGB format as alias of XRGB. Signed-off-by: Eugeniy Paltsev --- drivers/gpu/drm/arc/arcpgu_crtc.c | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/gpu/drm/arc/arcpgu_crtc.c b/drivers/gpu/drm/arc/arcpgu_crtc.c index 98

[PATCH V10] mm/debug: Add tests validating architecture page table helpers

This adds tests which will validate architecture page table helpers and other accessors in their compliance with expected generic MM semantics. This will help various architectures in validating changes to existing page table helpers or addition of new ones. This test covers basic page table entry
