commit c92c108403b09f75f3393588c2326ecad49ee2e2 upstream.

This reverts commit 5f38ac54e60562323ea4abb1bfb37d043ee23357.
This causes issues with rebooting and the 7800XT.

[ Upstream commit 58fca355ad37dcb5f785d9095db5f748b79c5dc2 ]

'stream_enc_regs' array is an array of dcn10_stream_enc_registers
structures. The array is initialized with four elements, corresponding
to the four calls to stream_enc_regs() in the array initializer. This
means that valid indices for this array are 0, 1, 2, and 3.

The error message 'stream_enc_regs' 4 &lt;= 5 below, is indicating that
there is an attempt to access this array with an index of 5, which is
out of bounds. This could lead to undefined behavior

Here, eng_id is used as an index to access the stream_enc_regs array. If
eng_id is 5, this would result in an out-of-bounds access on the
stream_enc_regs array.

Thus fixing Buffer overflow error in dcn301_stream_encoder_create
reported by Smatch:

This code prints the wrong variable in the warning message.  It should
print "i" instead of "info-&gt;offset".  On the first iteration "info" is
uninitialized leading to a crash and on subsequent iterations it prints
the previous offset instead of the current one.

The commit 8b45a26f2ba9 ("drm/msm/dpu: reserve cdm blocks for writeback
in case of YUV output") introduced a smatch warning about another
conditional block in dpu_encoder_helper_phys_cleanup() which had assumed
hw_pp will always be valid which may not necessarily be true.

Lets fix the other conditional block by making sure hw_pp is valid
before dereferencing it.

[ Upstream commit fcccdafd91f8bdde568b86ff70848cf83f029add ]

MSA MISC0 bit 1 to 7 contains Colorimetry Indicator Field.
dp_link_get_colorimetry_config() returns wrong colorimetry value
in the DP_TEST_DYNAMIC_RANGE_CEA case in the current implementation.
Hence fix this problem by having dp_link_get_colorimetry_config()

DP_TEST_DYNAMIC_RANGE_CEA.

Changes in V2:
-- drop retrieving colorimetry from colorspace
-- drop dr = link-&gt;dp_link.test_video.test_dyn_range assignment

Changes in V3:
-- move defined MISCr0a Colorimetry vale to dp_reg.h

[ Upstream commit 77e8aad5519e04f6c1e132aaec1c5f8faf41844f ]

Since the value of DP_TEST_BIT_DEPTH_8 is already left shifted, in the
BPC unknown case, the additional shift causes spill over to the other
bits of the [DP_CONFIGURATION_CTRL] register.
Fix this by changing the return value of dp_link_get_test_bits_depth()
in the BPC unknown case to (DP_TEST_BIT_DEPTH_8 &gt;&gt; DP_TEST_BIT_DEPTH_SHIFT).

[ Upstream commit 77e8aad5519e04f6c1e132aaec1c5f8faf41844f ]

Since the value of DP_TEST_BIT_DEPTH_8 is already left shifted, in the
BPC unknown case, the additional shift causes spill over to the other
bits of the [DP_CONFIGURATION_CTRL] register.
Fix this by changing the return value of dp_link_get_test_bits_depth()
in the BPC unknown case to (DP_TEST_BIT_DEPTH_8 &gt;&gt; DP_TEST_BIT_DEPTH_SHIFT).

commit 6ab502bc1cf3147ea1d8540d04b83a7a4cb6d1f1 upstream.

Some devices power the DSI PHY/PLL through a power rail that we model
as a GENPD. Enable runtime PM to make it suspendable.
