Hi Patrice, Alain, Could you help to take a look at this patchset, thanks. This series is the rebase to the newest kernel commit: 88b06399c9c766c283e070b022b5ceafa4f63f19 according to the request from: https://lore.kernel.org/lkml/ff2bc09d-1a17-50d4-d3ee-16fd3a86d7f1@foss.st.com/ The clk bug affects the kernel bootup on stm32f469-disco board in case display config(CONFIG_DRM_STM, CONFIG_DRM_STM_DSI, DRM_PANEL_ORISETECH_OTM8009A) enabled. If you want to test clk patch on stm32f429-disco board, the panel-ilitek-ili9341.c can be used for that purpose (CONFIG_DRM_STM, DRM_PANEL_ILITEK_ILI9341) i2c driver patch intent to fix the touch panel driver get data through i2c bus timeout issue. Best regards.

Could you post all the logs from u-boot startup to kernel log end. If possible, you can try my suggestion. - tar -jxf stm32_rootfs.tar.bz2 - add stm32_rootfs to your kernel config( enable initramfs) - make O=YOUR_KERNEL_OUT zImage dtbs LOADADDR=0x90008000 - create itb file (combine dtb and kernel, initramfs) by mkimage ./mkimage -f stm32.its stm32.itb (before above command, make sure you correct stm32.its adapt to your env) This process will make u-boot to load the kernel more simple. Thanks. Best Regards.

Yes, your log is ok. I tried to follow your way(dtb + uImage) to figure out why your kernel was hanging there, but no luck. You can find my log from [1] . (since my uImage is bigger than yours, i change the loadaddr to 0x90300000, 0x90306000) but there are some points we can check: - kernel config, you can find my config in [2], could you share yours to me as well, i can based on your configs to test. - uImage size (yours 1593664 bytes is quite smaller than mine, 2072864 bytes the difference based on kernel config and rootfs size) - cross tool chain (upload my toolchain to google drive [3]) - could you add initcall_debug to your bootargs, to see more log at kernel startup [1] kernel log based on dtb + uImage https://drive.google.com/file/d/1wnA5b3B_6MIb4PWZXn-3DlBbxpi41uSA/view?usp=sharing [2] kernel config https://drive.google.com/file/d/1oOJt3NRYor3-Uzjpzrujv3uvWguxYQQp/view?usp=sharing [3] arm-none-eabi- toolchain https://drive.google.com/file/d/1Aq0sF2Gi4y4qaDPnM2S0xCOowFSLZYJm/view?usp=sharing Best Regards Dillon > > > > > >> U-Boot > > >> U-Boot > > >> U-Boot > setenv loadaddr 0x90400000 > >> U-Boot > loady > >> ## Ready for binary (ymodem) download to 0x90400000 at 115200 bps... > >> CxyzModem - CRC mode, 156(SOH)/0(STX)/0(CAN) packets, 7 retries > >> ## Total Size = 0x00004cad = 19629 Bytes > >> U-Boot > setenv loadaddr 0x90406000 > >> U-Boot > loady > >> ## Ready for binary (ymodem) download to 0x90406000 at 115200 bps... > >> C- CRC mode, 12453(SOH)/0(STX)/0(CAN) packets, 4 retries > >> ## Total Size = 0x00185140 = 1593664 Bytes > >> U-Boot > bootm 0x90406000 - 0x90400000 > >> ## Booting kernel from Legacy Image at 90406000 ... > >> Image Name: Linux-5.13.0-rc1-00082-g9dbbd5cb > >> Image Type: ARM Linux Kernel Image (uncompressed) > >> Data Size: 1593600 Bytes = 1.5 MiB > >> Load Address: 90008000 > >> Entry Point: 90008000 > >> Verifying Checksum ...

From: Dillon Min <dillon.minfei@gmail.com> This seriese fix three i2c/clk bug for stm32 f4/f7 - kernel runing in sdram, i2c driver get data timeout - ltdc clk turn off after kernel console active - kernel hang in set ltdc clock rate clk bug found on stm32f429/f469-disco board Hi Patrice: below is the guide to verify the patch: setup test env with following files(link at below 'files link'): [1] u-boot-dtb.bin [2] rootfs zip file (used in kernel initramfs) [3] u-boot's mkimage to create itb file [4] kernel config file [5] my itb with-or-without i2c patch This patch based on kernel commit: 88b06399c9c766c283e070b022b5ceafa4f63f19 Note: panel-ilitek-ili9341.c is the driver which was submitted last year, but not get accepted. it's used to setup touch screen calibration, then test i2c. create itb file(please correct path of 'data'): ./mkimage -f stm32.its stm32.itb HW setup: console: PA9, PA10 usart0 serial@40011000 115200 8n1 -- flash u-boot.bin to stm32f429-disco on PC $ sudo openocd -f board/stm32f429discovery.cfg -c \ '{PATH-TO-YOUR-UBOOT}/u-boot-dtb.bin 0x08000000 exit reset' -- setup kernel load bootargs at u-boot U-Boot > setenv bootargs 'console=tty0 console=ttySTM0,115200 root=/dev/ram rdinit=/linuxrc loglevel=8 fbcon=rotate:2' U-Boot > loady;bootm (download stm32.dtb or your kernel with itb format, or download zImage, dtb) -- setup ts_calibrate running env on stm32f429-disco / # export TSLIB_CONFFILE=/etc/ts.conf / # export TSLIB_TSDEVICE=/dev/input/event0 / # export TSLIB_CONSOLEDEVICE=none / # export TSLIB_FBDEVICE=/dev/fb0 -- clear screen / # ./fb -- run ts_calibrate / # ts_calibrate (you can calibrate touchscreen now, and get below errors) [ 113.942087] stmpe-i2c0-0041: failed to read regs 0x52: -110 [ 114.063598] stmpe-i2c 0-0041: failed to read reg 0x4b: -16 [ 114.185629] stmpe-i2c 0-0041: failed to read reg 0x40: -16 [ 114.307257] stmpe-i2c 0-0041: failed to write reg 0xb: -16 ... with i2c patch applied, you will find below logs: RAW---------------------> 3164 908 183 118.110884 TS_READ_RAW----> x = 3164, y =908, pressure = 183 RAW---------------------> 3166 922 126 118.138946 TS_READ_RAW----> x = 3166, y = 922, pressure = 126 .... files link: https://drive.google.com/drive/folders/1qNbjChcB6UGtKzne2F5x9_WG_sZFyo3o?usp=sharing Dillon Min (4): drm/panel: Add ilitek ili9341 panel driver i2c: stm32f4: Fix stmpe811 get xyz data timeout issue clk: stm32: Fix stm32f429's ltdc driver hang in set clock rate clk: stm32: Fix ltdc's clock turn off by clk_disable_unused() after kernel startup drivers/clk/clk-stm32f4.c | 10 +- drivers/gpu/drm/panel/Kconfig | 12 + drivers/gpu/drm/panel/Makefile | 1 + drivers/gpu/drm/panel/panel-ilitek-ili9341.c | 1285 ++++++++++++++++++++++++++ drivers/i2c/busses/i2c-stm32f4.c | 12 +- 5 files changed, 1310 insertions(+), 10 deletions(-) create mode 100755 drivers/gpu/drm/panel/panel-ilitek-ili9341.c
