This patch parses MAX_FRL field to get the MAX rate in Gbps that
the HDMI 2.1 panel can support in FRL mode. Source need this
field to determine the optimal rate between the source and sink
during FRL training.

From: Swati Sharma
The HDMI2.1 extends HFVSDB (HDMI Forum Vendor Specific
Data block) to have fields related to newly defined methods of FRL
(Fixed Rate Link) levels, number of lanes supported, DSC Color bit
depth, VRR min/max, FVA (Fast Vactive), ALLM etc.
This patch adds the new HFVSDB fields
This patch parses HFVSDB fields for DSC1.2 capabilities of an
HDMI2.1 sink. These fields are required by a source to understand the
DSC capability of the sink, to set appropriate PPS parameters,
before transmitting compressed data stream.
v2: Addressed following issues as suggested by Uma Shankar:
This patch series attempts to add support for a DP-HDMI2.1 Protocol
Convertor. The VESA spec for the HDMI2.1 PCON are proposed in Errata

The details are mentioned in DP to HDMI2.1 PCON Enum/Con
When a source supporting DSC1.1 is connected to DSC1.2 HDMI2.1 sink
via DP HDMI2.1 PCON, the PCON can be configured to decode the
DSC1.1 compressed stream and encode to DSC1.2. It then sends the
DSC1.2 compressed stream to the HDMI2.1 sink.

HDMI2.1 PCON advertises Max FRL bandwidth supported by the PCON and
by the sink.
This patch captures these in dfp cap structure in intel_dp and uses
these to prune connector modes that cannot be supported by the PCON

v2: Addressed review comments from Uma Shankar:
-tweaked
The DP-HDMI2.1 PCON spec provides way for a source to set PPS
parameters: slice height, slice width and bits_per_pixel, based on
the HDMI2.1 sink capabilities. The DSC encoder of the PCON will

Replace printk() with pr_err(), pr_warn() and pr_info(). Do not split long
strings, for easier grepping. Use `__func__` whenever applicable.
fbcon_prepare_logo() has more than one callers, use "fbcon_prepare_logo:"

Some dongles, such as Apple, required link training done at irq_hpd
request instead of plugin request. This patch promote irq_hpd hanlder
to handle link training and setup hpd_state correctly.

Hi,
This patchset is for adding support for the Asia Better Technology (aka.

While being 320x480 it is actually 4:3 with non-square pixels, and
requires a specific bus format, as the pixel ordering changes each line

Introduce quirk QUIRK_RENDERCLEAR_REDUCED, which will be used

Reading VCO rate for this PLL can cause boot stalls, if it is not
enabled. Guard clk_hw_get_rate with a call to

Fix the checkpath.pl issue on fb_watterott.c. write_vmem and
write_vmem_8bit functions are within non-atomic context and can
safely use usleep_range.

Added function quirk_renderclear_reduced to set QUIRK_RENDERCLEAR_REDUCED
for designated platforms. Applying QUIRK_RENDERCLEAR_REDUCED for
the HP Pavilion Mini 300-020 prevents a GPU hang.

Some hardware variants contain a system cache or the last level
cache(llc). This cache is typically a large block which is shared
by multiple clients on the SOC. GPU uses the system cache to cache
both the GPU data buffers(like textures) as well the SMMU pagetables.
This helps with improved render
