Just say which boards need it for which functionality/features. Three sentences are enough. Best regards, Krzysztof

The mediatek display driver fails to probe on mt8173 and mt8183 in v6.14-rc4, with the following errors: mt8173: platform 1401b000.dsi: deferred probe pending: mtk-dsi: Failed to get hs clock platform 14025000.hdmi: deferred probe pending: (reason unknown) i2c 1-0008: deferred probe pending: (reason unknown) mt8183: platform 14014000.dsi: deferred probe pending: mtk-dsi: Failed to get hs clock i2c 4-0058: deferred probe pending: anx7625: fail to find dsi host. Enabling CONFIG_PHY_MTK_MIPI_DSI=y in drm-ci resolves this error, but mt8173 still fails with, [drm:mtk_dsi_host_attach] *ERROR* failed to add dsi_host component: -517 panel-simple-dp-aux aux-1-0008: DP AUX done_probing() can't defer panel-simple-dp-aux aux-1-0008: probe with driver panel-simple-dp-aux failed with error -22 Enabling CONFIG_PHY_MTK_XSPHY=y and CONFIG_PHY_MTK_HDMI=y in drm-ci resolves this issue for mt8173. So enable these PHY configs for mediatek platforms. Signed-off-by: Vignesh Raman <vignesh.raman@collabora.com> --- arch/arm64/configs/defconfig | 3 +++ 1 file changed, 3 insertions(+)
