2023-10-09drm/msm/a6xx: Add missing regs for A7XXKonrad Dybcio2-0/+17

2023-10-09dt-bindings: display/msm/gmu: Allow passing QMP handleKonrad Dybcio1-0/+7
When booting the GMU, the QMP mailbox should be pinged about some tunables (e.g. adaptive clock distribution state). To achieve that, a reference to it is necessary. Allow it and require it with A730.

2023-10-09dt-bindings: display/msm/gmu: Add Adreno 7[34]0 GMUKonrad Dybcio1-1/+39
The GMU on the A7xx series is pretty much the same as on the A6xx parts. It's now "smarter", needs a bit less register writes and controls more things (like inter-frame power collapse) mostly internally (instead of us having to write to G[PM]U_[CG]X registers from APPS) The only difference worth mentioning is the now-required DEMET clock, which is strictly required for things like asserting reset lines, not turning it on results in GMU not being fully functional (all OOB requests would fail and HFI would hang after the first submitted OOB). Describe the A730 and A740 GMU.

2023-10-09drm/msm/dp: skip validity check for DP CTS EDID checksumJani Nikula1-19/+2
The DP CTS test for EDID last block checksum expects the checksum for the last block, invalid or not. Skip the validity check. For the most part (*), the EDIDs returned by drm_get_edid() will be valid anyway, and there's the CTS workaround to get the checksum for completely invalid EDIDs. See commit 7948fe12d47a ("drm/msm/dp: return correct edid checksum after corrupted edid checksum read"). This lets us remove one user of drm_edid_block_valid() with hopes the function can be removed altogether in the future. (*) drm_get_edid() ignores checksum errors on CTA extensions.

In preparation to reworking IRQ indcies, stop using raw IRQ indices in kernel output (both printk and debugfs). Instead use a pair of register index and bit. This corresponds closer to the values in HW catalog.

Currently, dpu_plane_atomic_check() does not check whether the plane can process the image without exceeding the per chipset limits for MDP clock. This leads to underflow issues because the SSPP is not able to complete the processing for the data rate of the display.

2023-09-21drm/msm/dsi: skip the wait for video mode done if not applicableAbhinav Kumar1-0/+12
dsi_wait4video_done() API waits for the DSI video mode engine to become idle so that we can transmit the DCS commands in the beginning of BLLP. However, with the current sequence, the MDP timing engine is turned on after the panel's pre_enable() callback which can send out the DCS commands needed to power up the panel. During those cases, this API will always timeout and print out the error spam leading to long bootup times and log flooding. Fix this by checking if the DSI video engine was actually busy before waiting for it to become idle otherwise this is a redundant wait. changes in v2: - move the reg read below the video mode check - minor fixes in commit text Closes: https://gitlab.freedesktop.org/drm/msm/-/issues/34 Fixes: a689554ba6ed ("drm/msm: Initial add DSI connector support") Signed-off-by: Abhinav Kumar <quic_abhinavk@quicinc.com> Reviewed-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> Patchwork: https://patchwork.freedesktop.org/patch/557853/ Link: https://lore.kernel.org/r/20230915204426.19011-1-quic_abhinavk@quicinc.com

2023-09-21drm/msm/dp: do not reinitialize phy unless retry during link trainingKuogee Hsieh1-7/+6
DP PHY re-initialization done using dp_ctrl_reinitialize_mainlink() will cause PLL unlocked initially and then PLL gets locked at the end of initialization. PLL_UNLOCKED interrupt will fire during this time if the interrupt mask is enabled. However currently DP driver link training implementation incorrectly re-initializes PHY unconditionally during link training as the PHY was already configured in dp_ctrl_enable_mainlink_clocks(). Fix this by re-initializing the PHY only if the previous link training failed.

2023-09-17stat: remove no-longer-used helper macrosLinus Torvalds1-6/+0
The choose_32_64() macros were added to deal with an odd inconsistency between the 32-bit and 64-bit layout of 'struct stat' way back when in commit a52dd971f947 ("vfs: de-crapify "cp_new_stat()" function"). Then a decade later Mikulas noticed that said inconsistency had been a mistake in the early x86-64 port, and shouldn't have existed in the first place. So commit 932aba1e1690 ("stat: fix inconsistency between struct stat and struct compat_stat") removed the uses of the helpers. But the helpers remained around, unused. Get rid of them.
