Starting from GM204, certain registers are no longer accessible by the host (or unsigned PMU firmware). This commit implements devinit on PMU, using a signed microcode image, and devinit data, from the VBIOS. Signed-off-by:Ben Skeggs <bskeggs@redhat.com>

We're about to need to be able to fetch additional chunks of data beyond the primary bios image, which makes fetching a lot more complicated. This splits out the verious shadowing routines to be nothing more than very dumb "fetch this much data from this offset" routines, and leaves the logic of what and how much to fetch in common code.

Some Tegra drivers might be compiled as kernel modules, and they need the fuse information for initialization. One example is the GK20A Nouveau driver. It needs the GPU speedo value to calculate frequency-voltage table. So export the tegra_sku_info. Signed-off-by:

The branch is based on a merge of drm-next and Simon's tags/renesas-dt-du-for- v3.19 available at git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas.git, the latter having been pulled in the ARM SoC tree for v3.19. Compared to v1, I've rebased my branch on a later drm-next, added Julia's error return code fix, and documented the "drm: Decouple EDID parsing from I2C adapter" patch properly. v1: Here's a pull request that adds HDMI support to the R-Car DU driver, including a new slave encoder driver for the adv7511. * 'drm/du/adv7511' of git://linuxtv.org/pinchartl/fbdev: drm: Add adv7511 encoder driver video: Add ADV751[13] DT bindings documentation drm: Decouple EDID parsing from I2C adapter drm: rcar-du: Add HDMI encoder and connector support drm: rcar-du: Replace drm_encoder with drm_slave_encoder drm: rcar-du: Replace direct DRM encoder access with cast macro drm: rcar-du: Pass the encoder DT node to rcar_du_encoder_init() drm: rcar-du: Remove platform data support drm: rcar-du: fix error return code ARM: shmobile: koelsch: Enable DU device in DT ARM: shmobile: koelsch-reference: Remove DU platform device ARM: shmobile: lager: Enable DU device in DT ARM: shmobile: lager-reference: Remove DU platform device ARM: shmobile: marzen: Enable DU device in DT ARM: shmobile: dts: Add common file for AA104XD12 panel ARM: shmobile: r8a7791: Add DU node to device tree ARM: shmobile: r8a7790: Add DU node to device tree ARM: shmobile: r8a7779: Add DU node to device tree ARM: shmobile: Remove FSF address from copyright headers

The drm_get_edid() function performs direct I2C accesses to read EDID blocks, assuming that the monitor DDC interface is directly connected to the I2C bus. It can't thus be used with HDMI encoders that control the DDC bus and expose EDID blocks through a different interface. Refactor drm_do_get_edid() to take a block read callback function instead of an I2C adapter, and export it for direct use by drivers. As in the general case the DDC bus is accessible by the kernel at the I2C level, drivers must make all reasonable efforts to expose it as an I2C adapter and use drm_get_edid() instead of abusing this function.

Laurent Pinchart authored
DRM slave encoders require their associated struct drm_encoder instance to be embedded in a struct drm_slave_encoder. This makes processing encoders regardless of their types needlessly and painfully complex in drivers that use a mix of slave encoders and custom encoders. Such a driver will need to either create drm_slave_encoder instances that fake their embedded encoder instance, or to turn all drm_encoder instances into drm_slave_encoder instances. Between the two evils, one must choose the lesser. Use drm_slave_encoder everywhere. Signed-off-by: -

The imx-drm driver was put into staging mostly for the following reasons, all of which have been addressed or superseded: - convert the irq driver to use linear irq domains - work out the device tree bindings, this lead to the common of_graph bindings being used - factor out common helper functions, this mostly resulted in the component framework and drm of_graph helpers. Before adding new fixes, and certainly before adding new features, move it into its proper place below drivers/gpu/drm. Signed-off-by:
