[PATCH] video: simplefb: modernise DT parsing
by Caleb Connolly 21 Apr '24

21 Apr '24

simplefb was using old style FDT parsing which doesn't behave well in combination with livetree. Update it to use ofnode instead and add a missing null check for the "format" property. Standardise the error logging while we're here.

[PATCH 0/4] Simplefb and fb reservation related updates
by Devarsh Thakkar 21 Apr '24

21 Apr '24

This adds support for simple-framebuffer reservation using video handoff when splash is enabled at SPL stage. Also adds helper function to only enable framebuffer reservation without enabling simple-framebuffer in case user want to continue display bootloader splash without displaying anything else in between until kernel boots up. Lastly, it enables above support on AM62x.

[PATCH v6 00/18] Add T114 video support
by Svyatoslav Ryhel 21 Apr '24

21 Apr '24

T114 is not that different from T30 and all T30 drivers will work on T114 as well with some adjustments. Patches propose general improvements for existing Tegra DC and DSI drivers as well Tegra 114 video support (experimentl). Commits pass buildman for tegra. --- Changes from v5: - backlight enable moved to the last step of setup for DSI - parameterized V- and H-sync polarities - added framebuffer clearing on probe to avoid glitches - backlight enable moved after DC is fully configured - fixed printing framebuffer pointer instead of address - moved scdiv calculation to tegra DSI if it is used Changes from v4: - fixed typo in max rate to be divided (400KHz > 400MHz) Changes from v3: - fixed the clock divider calculation if PLLD/D2 is used - removed unnecessary pre-configuration - set correct video FIFO depth for DSI Changes from v2: - fixed image distortion on devices with 180deg rotation Changes from v1: - reworked patchset entirely - diverged DC configuration per-SOC - consolidated dc headers from different SOC gen - initial support of DC detection (tegra has 2 DC) - added PLLD2 support, resets and powergating - added T114+ MIPI calibration - added DSI detection (tegra has 2 DSI) and resets --- Jonas Schwöbel (6): video: tegra20: dc: fix printing of framebuffer address video: tegra20: dc: enable backlight after DC is configured video: tegra20: dc: clean framebuffer memory block video: tegra20: dsi: remove pre-configuration video: tegra20: dsi: set correct fifo depth video: tegra20: dsi: use set_backlight for backlight only Svyatoslav Ryhel (12): video: tegra20: dc: diverge DC per-SOC video: tegra20: dc: fix image shift on rotated panels video: tegra20: consolidate DC header video: tegra20: dc: pass DC id to internal devices video: tegra20: dc: add PLLD2 parent support video: tegra20: dc: add reset support video: tegra20: dc: add powergate video: tegra20: dc: configure behavior if PLLD/D2 is used video: tegra20: dc: parameterize V- and H-sync polarities video: tegra20: add MIPI calibration driver video: tegra20: dsi: add T114 support video: tegra20: dsi: add reset support arch/arm/dts/tegra114-u-boot.dtsi | 13 + arch/arm/dts/tegra114.dtsi | 4 +- arch/arm/dts/tegra30-u-boot.dtsi | 4 + arch/arm/dts/tegra30.dtsi | 2 +- arch/arm/include/asm/arch-tegra/dc.h | 13 +- arch/arm/include/asm/arch-tegra114/pwm.h | 13 + arch/arm/include/asm/arch-tegra20/display.h | 28 -- arch/arm/include/asm/arch-tegra30/display.h | 28 -- drivers/video/tegra20/Makefile | 2 +- drivers/video/tegra20/tegra-dc.c | 239 +++++++++++++----- drivers/video/tegra20/tegra-dc.h | 45 ++++ drivers/video/tegra20/tegra-dsi.c | 122 ++++++++- .../video/tegra20/tegra-dsi.h | 24 +- drivers/video/tegra20/tegra-mipi.c | 188 ++++++++++++++ drivers/video/tegra20/tegra-pwm-backlight.c | 3 +- 15 files changed, 583 insertions(+), 145 deletions(-) create mode 100644 arch/arm/include/asm/arch-tegra114/pwm.h delete mode 100644 arch/arm/include/asm/arch-tegra20/display.h delete mode 100644 arch/arm/include/asm/arch-tegra30/display.h create mode 100644 drivers/video/tegra20/tegra-dc.h rename arch/arm/include/asm/arch-tegra30/dsi.h => drivers/video/tegra20/tegra-dsi.h (90%) create mode 100644 drivers/video/tegra20/tegra-mipi.c -- 2.40.1

[PATCH v2 00/16] pxe: Allow extlinux booting without CMDLINE enabled
by Simon Glass 20 Apr '24

20 Apr '24

This series is the culmanation of the current line of refactoring series. It adjusts pxe to call the booting functionality directly rather than going through the command-line interface. With this is is possible to boot using the extlinux bootmeth without the command line enabled. It also updates fastboot to do a similar thing. This is cmdf (part f of CMDLINE refactoring) It depends on dm/cmde-working which depends on dm/cmdd-working which depends on dm/bootstda-working which depends on dm/cmdc-working Changes in v2: - Use unmap_sysmem() too - Drop check for NULL with env_set() - Avoid changing the logic when a command is not set - Split out the strlcpy() change into its own patch - Update commit message to mention booti - Use bootm_init() instead of memset() Simon Glass (16): boot: Reorder FIT and BOOTSTD to be first bootm: Add a Kconfig option for bootm functionality bootm: Make OS booting dependent on BOOTM treewide: Make arch-specific bootm code depend on BOOTM boot: Update SYS_BOOTM_LEN to depend on BOOTM fastboot: Change fastboot_buf_addr to an address bootm: Make cmdline optional with bootm_boot_start() fastboot: Remove dependencies on CMDLINE doc: Mention fastboot dependency on CMDLINE pxe: Use strlcpy() instead of strcpy() in label_boot() pxe: Refactor to reduce the size of label_boot() pxe: Refactor to avoid over-using bootm_argv pxe: Move calculation of FDT file into a function pxe: Allow booting without CMDLINE for bootm methods pxe: Allow booting without CMDLINE for the zboot method x86: Drop message about features being missing with 64-bit arch/arc/lib/Makefile | 2 +- arch/arm/lib/Makefile | 2 +- arch/m68k/lib/Makefile | 2 +- arch/microblaze/lib/Makefile | 2 +- arch/mips/lib/Makefile | 2 +- arch/nios2/lib/Makefile | 2 +- arch/powerpc/lib/Makefile | 2 +- arch/riscv/lib/Makefile | 2 +- arch/sandbox/lib/Makefile | 2 +- arch/sh/lib/Makefile | 2 +- arch/x86/lib/Makefile | 2 +- arch/x86/lib/spl.c | 2 +- arch/xtensa/lib/Makefile | 2 +- boot/Kconfig | 99 ++++- boot/Makefile | 2 +- boot/pxe_utils.c | 360 ++++++++++-------- cmd/Kconfig | 50 +-- cmd/fastboot.c | 2 +- configs/colibri_vf_defconfig | 2 +- configs/iot_devkit_defconfig | 2 +- configs/mx6memcal_defconfig | 2 +- configs/tools-only_defconfig | 2 +- configs/xilinx_versal_mini_defconfig | 2 +- configs/xilinx_versal_mini_emmc0_defconfig | 2 +- configs/xilinx_versal_mini_emmc1_defconfig | 2 +- configs/xilinx_versal_mini_ospi_defconfig | 2 +- configs/xilinx_versal_mini_qspi_defconfig | 2 +- configs/xilinx_versal_net_mini_defconfig | 2 +- configs/xilinx_versal_net_mini_emmc_defconfig | 2 +- configs/xilinx_versal_net_mini_ospi_defconfig | 2 +- configs/xilinx_versal_net_mini_qspi_defconfig | 2 +- configs/xilinx_zynqmp_mini_defconfig | 2 +- configs/xilinx_zynqmp_mini_emmc0_defconfig | 2 +- configs/xilinx_zynqmp_mini_emmc1_defconfig | 2 +- configs/xilinx_zynqmp_mini_nand_defconfig | 2 +- .../xilinx_zynqmp_mini_nand_single_defconfig | 2 +- configs/xilinx_zynqmp_mini_qspi_defconfig | 2 +- configs/zynq_cse_nand_defconfig | 2 +- configs/zynq_cse_nor_defconfig | 2 +- configs/zynq_cse_qspi_defconfig | 2 +- doc/android/fastboot.rst | 1 + doc/board/emulation/qemu-x86.rst | 2 +- drivers/fastboot/Kconfig | 1 - drivers/fastboot/fb_command.c | 17 +- drivers/fastboot/fb_common.c | 37 +- include/bootm.h | 2 +- include/fastboot-internal.h | 2 +- include/fastboot.h | 6 +- 48 files changed, 350 insertions(+), 301 deletions(-) -- 2.43.0.472.g3155946c3a-goog

[PATCH] efi_loader: use event callback for initrd deregistration

[PATCH] usb: musb-new: sunxi: support usage with DM_USB_GADGET
by Aren Moynihan 16 Apr '24

16 Apr '24

Add support for building the sunxi-musb driver with DM_USB_GADGET including adding a separate IRQ handling function and registering the driver with the musb system differently. The implementation of usb_gadget_register_driver from musb-new/musb_uboot.c only works when the gadget driver for the device has already been probed and has called musb_register. On the pinephone (using a allwinner a64 processor) this causes issues when trying to use usb gadget mode (such as from the ums command) and CONFIG_USB_ETHER is disabled. The implementation of usb_gadget_register_driver provided when DM_USB_GADGET is enabled will probe the necessary drivers when it's called. Without the patch, this is what the error condition looks like: => ums 0 mmc 1 UMS: LUN 0, dev mmc 1, hwpart 0, sector 0x0, count 0x3a3e000 Controller uninitialized g_dnl_register: failed!, error: -6 g_dnl_register failed based on: commit 2e4865bc6486 ("musb-new: omap2430: fix compiling in DM_USB_GADGET config") Signed-off-by: Aren Moynihan <aren(a)peacevolution.org> --- I don't fully understand what's going on here. Some gadget mode drivers, such as usb ether (in usb_ether_init) will initialize the usb gadget driver, but others (ums, fastboot) don't seem to do this, or don't do it early enough, so they don't work. drivers/usb/musb-new/sunxi.c | 20 ++++++++++++++++++++ 1 file changed, 20 insertions(+) diff --git a/drivers/usb/musb-new/sunxi.c b/drivers/usb/musb-new/sunxi.c index 91f082fe05e..9b06f49ce47 100644 --- a/drivers/usb/musb-new/sunxi.c +++ b/drivers/usb/musb-new/sunxi.c @@ -429,6 +429,17 @@ static struct musb_hdrc_config musb_config_h3 = { .ram_bits = SUNXI_MUSB_RAM_BITS, }; +#ifdef CONFIG_DM_USB_GADGET +int dm_usb_gadget_handle_interrupts(struct udevice *dev) +{ + int n = 0; + struct musb_host_data *host = dev_get_priv(dev); + + host->host->isr(0, host->host); + return 0; +} +#endif + static int musb_usb_probe(struct udevice *dev) { struct sunxi_glue *glue = dev_get_priv(dev); @@ -482,6 +493,15 @@ static int musb_usb_probe(struct udevice *dev) ret = musb_lowlevel_init(host); if (!ret) printf("Allwinner mUSB OTG (Host)\n"); +#elifdef CONFIG_DM_USB_GADGET + pdata.mode = MUSB_PERIPHERAL; + host->host = musb_init_controller(&pdata, &glue->dev, base); + if (!host->host) + return -EIO; + + ret = usb_add_gadget_udc(&glue->dev, &host->host->g); + if (!ret) + printf("Allwinner mUSB OTG (Peripheral)\n"); #else pdata.mode = MUSB_PERIPHERAL; host->host = musb_register(&pdata, &glue->dev, base); -- 2.43.0
