I am coming into the conversation late but I am running into an issue with the Raspberry Pi 4 not booting on linux-next, which appears to be due to this patch now in mainline as commit d9765e41d8e9 ("dma-pool: do not allocate pool memory from CMA") combined with https://lore.kernel.org/lkml/20200725014529.1143208-2-jiaxun.yang@flygoat.com/ in -next: [ 1.423163] raspberrypi-firmware soc:firmware: Request 0x00000001 returned status 0x00000000 [ 1.431883] raspberrypi-firmware soc:firmware: Request 0x00030046 returned status 0x00000000 [ 1.443888] raspberrypi-firmware soc:firmware: Request 0x00030043 returned status 0x00000000 [ 1.452527] raspberrypi-exp-gpio soc:firmware:gpio: Failed to get GPIO 0 config (-22 80) [ 1.460836] raspberrypi-firmware soc:firmware: Request 0x00030043 returned status 0x00000000 [ 1.469445] raspberrypi-exp-gpio soc:firmware:gpio: Failed to get GPIO 1 config (-22 81) [ 1.477735] raspberrypi-firmware soc:firmware: Request 0x00030043 returned status 0x00000000 [ 1.486350] raspberrypi-exp-gpio soc:firmware:gpio: Failed to get GPIO 2 config (-22 82) [ 1.494639] raspberrypi-firmware soc:firmware: Request 0x00030043 returned status 0x00000000 [ 1.503246] raspberrypi-exp-gpio soc:firmware:gpio: Failed to get GPIO 3 config (-22 83) [ 1.511529] raspberrypi-firmware soc:firmware: Request 0x00030043 returned status 0x00000000 [ 1.520131] raspberrypi-exp-gpio soc:firmware:gpio: Failed to get GPIO 4 config (-22 84) [ 1.528414] raspberrypi-firmware soc:firmware: Request 0x00030043 returned status 0x00000000 [ 1.537017] raspberrypi-exp-gpio soc:firmware:gpio: Failed to get GPIO 5 config (-22 85) [ 1.545299] raspberrypi-firmware soc:firmware: Request 0x00030043 returned status 0x00000000 [ 1.553903] raspberrypi-exp-gpio soc:firmware:gpio: Failed to get GPIO 6 config (-22 86) [ 1.562184] raspberrypi-firmware soc:firmware: Request 0x00030043 returned status 0x00000000 [ 1.570787] raspberrypi-exp-gpio soc:firmware:gpio: Failed to get GPIO 7 config (-22 87) [ 1.579897] raspberrypi-firmware soc:firmware: Request 0x00030030 returned status 0x00000000 [ 1.589419] raspberrypi-firmware soc:firmware: Request 0x00028001 returned status 0x00000000 [ 1.599391] raspberrypi-firmware soc:firmware: Request 0x00030043 returned status 0x00000000 [ 1.608018] raspberrypi-exp-gpio soc:firmware:gpio: Failed to get GPIO 1 config (-22 81) [ 1.616313] raspberrypi-firmware soc:firmware: Request 0x00030043 returned status 0x00000000 [ 1.624932] raspberrypi-exp-gpio soc:firmware:gpio: Failed to get GPIO 1 config (-22 81) [ 1.633195] pwrseq_simple: probe of wifi-pwrseq failed with error -22 [ 1.643904] raspberrypi-firmware soc:firmware: Request 0x00030043 returned status 0x00000000 [ 1.652544] raspberrypi-exp-gpio soc:firmware:gpio: Failed to get GPIO 2 config (-22 82) [ 1.660839] raspberrypi-firmware soc:firmware: Request 0x00030041 returned status 0x00000000 [ 1.669446] raspberrypi-exp-gpio soc:firmware:gpio: Failed to get GPIO 2 state (-22 82) [ 1.677727] leds-gpio: probe of leds failed with error -22 [ 1.683735] raspberrypi-firmware soc:firmware: Request 0x00030043 returned status 0x00000000 [ 1.692346] raspberrypi-exp-gpio soc:firmware:gpio: Failed to get GPIO 6 config (-22 86) [ 1.700636] raspberrypi-firmware soc:firmware: Request 0x00030043 returned status 0x00000000 [ 1.709240] raspberrypi-exp-gpio soc:firmware:gpio: Failed to get GPIO 6 config (-22 86) [ 1.717496] reg-fixed-voltage: probe of sd_vcc_reg failed with error -22 [ 1.725546] raspberrypi-firmware soc:firmware: Request 0x00030043 returned status 0x00000000 [ 1.734176] raspberrypi-exp-gpio soc:firmware:gpio: Failed to get GPIO 4 config (-22 84) [ 1.742465] raspberrypi-firmware soc:firmware: Request 0x00030043 returned status 0x00000000 [ 1.751072] raspberrypi-exp-gpio soc:firmware:gpio: Failed to get GPIO 4 config (-22 84) [ 1.759332] gpio-regulator: probe of sd_io_1v8_reg failed with error -22 [ 1.768042] raspberrypi-firmware soc:firmware: Request 0x00028001 returned status 0x00000000 [ 1.780871] ALSA device list: [ 1.783960] No soundcards found.

I am coming into the conversation late but I am running into an issue with the Raspberry Pi 4 not booting on linux-next, which appears to be due to this patch now in mainline as commit d9765e41d8e9 ("dma-pool: do not allocate pool memory from CMA") combined with https://lore.kernel.org/lkml/20200725014529.1143208-2-jiaxun.yang@flygoat.com/ in -next: [ 1.423163] raspberrypi-firmware soc:firmware: Request 0x00000001 returned status 0x00000000 [ 1.431883] raspberrypi-firmware soc:firmware: Request 0x00030046 returned status 0x00000000 [ 1.443888] raspberrypi-firmware soc:firmware: Request 0x00030043 returned status 0x00000000 [ 1.452527] raspberrypi-exp-gpio soc:firmware:gpio: Failed to get GPIO 0 config (-22 80) [ 1.460836] raspberrypi-firmware soc:firmware: Request 0x00030043 returned status 0x00000000 [ 1.469445] raspberrypi-exp-gpio soc:firmware:gpio: Failed to get GPIO 1 config (-22 81) [ 1.477735] raspberrypi-firmware soc:firmware: Request 0x00030043 returned status 0x00000000 [ 1.486350] raspberrypi-exp-gpio soc:firmware:gpio: Failed to get GPIO 2 config (-22 82) [ 1.494639] raspberrypi-firmware soc:firmware: Request 0x00030043 returned status 0x00000000 [ 1.503246] raspberrypi-exp-gpio soc:firmware:gpio: Failed to get GPIO 3 config (-22 83) [ 1.511529] raspberrypi-firmware soc:firmware: Request 0x00030043 returned status 0x00000000 [ 1.520131] raspberrypi-exp-gpio soc:firmware:gpio: Failed to get GPIO 4 config (-22 84) [ 1.528414] raspberrypi-firmware soc:firmware: Request 0x00030043 returned status 0x00000000 [ 1.537017] raspberrypi-exp-gpio soc:firmware:gpio: Failed to get GPIO 5 config (-22 85) [ 1.545299] raspberrypi-firmware soc:firmware: Request 0x00030043 returned status 0x00000000 [ 1.553903] raspberrypi-exp-gpio soc:firmware:gpio: Failed to get GPIO 6 config (-22 86) [ 1.562184] raspberrypi-firmware soc:firmware: Request 0x00030043 returned status 0x00000000 [ 1.570787] raspberrypi-exp-gpio soc:firmware:gpio: Failed to get GPIO 7 config (-22 87) [ 1.579897] raspberrypi-firmware soc:firmware: Request 0x00030030 returned status 0x00000000 [ 1.589419] raspberrypi-firmware soc:firmware: Request 0x00028001 returned status 0x00000000 [ 1.599391] raspberrypi-firmware soc:firmware: Request 0x00030043 returned status 0x00000000 [ 1.608018] raspberrypi-exp-gpio soc:firmware:gpio: Failed to get GPIO 1 config (-22 81) [ 1.616313] raspberrypi-firmware soc:firmware: Request 0x00030043 returned status 0x00000000 [ 1.624932] raspberrypi-exp-gpio soc:firmware:gpio: Failed to get GPIO 1 config (-22 81) [ 1.633195] pwrseq_simple: probe of wifi-pwrseq failed with error -22 [ 1.643904] raspberrypi-firmware soc:firmware: Request 0x00030043 returned status 0x00000000 [ 1.652544] raspberrypi-exp-gpio soc:firmware:gpio: Failed to get GPIO 2 config (-22 82) [ 1.660839] raspberrypi-firmware soc:firmware: Request 0x00030041 returned status 0x00000000 [ 1.669446] raspberrypi-exp-gpio soc:firmware:gpio: Failed to get GPIO 2 state (-22 82) [ 1.677727] leds-gpio: probe of leds failed with error -22 [ 1.683735] raspberrypi-firmware soc:firmware: Request 0x00030043 returned status 0x00000000 [ 1.692346] raspberrypi-exp-gpio soc:firmware:gpio: Failed to get GPIO 6 config (-22 86) [ 1.700636] raspberrypi-firmware soc:firmware: Request 0x00030043 returned status 0x00000000 [ 1.709240] raspberrypi-exp-gpio soc:firmware:gpio: Failed to get GPIO 6 config (-22 86) [ 1.717496] reg-fixed-voltage: probe of sd_vcc_reg failed with error -22 [ 1.725546] raspberrypi-firmware soc:firmware: Request 0x00030043 returned status 0x00000000 [ 1.734176] raspberrypi-exp-gpio soc:firmware:gpio: Failed to get GPIO 4 config (-22 84) [ 1.742465] raspberrypi-firmware soc:firmware: Request 0x00030043 returned status 0x00000000 [ 1.751072] raspberrypi-exp-gpio soc:firmware:gpio: Failed to get GPIO 4 config (-22 84) [ 1.759332] gpio-regulator: probe of sd_io_1v8_reg failed with error -22 [ 1.768042] raspberrypi-firmware soc:firmware: Request 0x00028001 returned status 0x00000000 [ 1.780871] ALSA device list: [ 1.783960] No soundcards found.

I am unsure if it is related to the issue that Amit is having or if that makes sense at all but I can reliably reproduce it. v5.8-rc1: OK v5.8-rc1 + d9765e41d8e9e: OK v5.8-rc1 + "of_address: Add bus type match for pci ranges parser": OK v5.8-rc1 + both: BROKEN I wanted to test the series to see if this fixes anything. If you would prefer a different thread for this or further information, please let me know.
